Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage device capable of massaging a scalp or the like by repeating an operation of compressing the skin in a plane direction (a direction along the plane direction).

[0002]

2. Description of the Related Art Conventionally, scalp massage has been effective for hair growth of hair. For this reason, various types of scalp massage devices have been proposed. The most common examples of these massage devices are so-called massage brushes, which are provided with rigid brushes or comb teeth on a rubber-elastic base formed in a convex shape with a transverse cross section. When the scalp is rubbed or beaten with this, the tip of the brush or the comb teeth moderately stimulates the scalp to increase the blood flow under the skin, thereby exhibiting a massage effect. Some brushes or comb teeth have rubber-elastic spheres formed at the tips to enhance the frictional effect and prevent damage to the scalp when struck.

As another example of a massage device, a spherical projection is formed on a surface that comes into contact with the skin, and this projection is manually pressed against the scalp or other skin, or is vibrated perpendicularly to the skin by electric power. There are also known those that stimulate the skin or those that embed a magnet in a spherical projection, press the projection to stimulate the skin, and enhance the subcutaneous blood circulation by magnetism to enhance the massage effect.

[0004]

The massage effect on the skin, such as the scalp, is generally said to rub or press against the skin to stimulate subcutaneous capillaries, thereby increasing blood circulation. In particular, in the case of the scalp and the like, the effect of preventing itching by massage is also expected. However, conventional massage devices merely rub the skin in one direction (not the action of compressing the skin in its surface direction) or press it perpendicularly to the skin surface, and the skin is Massage could not be performed by a movement that stretches in the direction of.

[0005] The present inventors have found that a very high exhilarating feeling can be obtained when a test is performed by giving a motion of compressing the scalp in the plane direction, and as a result of earnest research, the present invention has been reached. . Accordingly, an object of the present invention is to provide a massage device that can massage the skin while compressing the skin in the surface direction.

[0006]

According to a first aspect of the present invention, there is provided a massage device comprising a pair of massage members each having a projection surface having a plurality of projections for massaging in contact with the skin. The pair of massage members are arranged side by side, and the pair of massage members are swingable such that the respective projection surfaces alternately move in a direction facing each other and away from each other with respect to the intermediate line, and the projection main body is A projection main body made of a hard material, and a head made of a soft material provided at the tip of the projection main body. And a claw portion for preventing overhanging deformation is provided. Instead of providing the claw portion, at least the distal end portion of the projection main body has a flat shape, and a head made of a soft material is provided at least in the swinging inner direction of the flat portion.

Further, the pair of massage members are provided with rocking means having respective rocking axes, arranged in parallel with the base, and for rocking the pair of massage members symmetrically with respect to the rocking shaft. And the pair of massage members can be swingably connected by a connecting member that can be bent into a “U” shape or a “U” shape in a side view.

[0008] The connecting member is a spring member.
The pair of massage members are each provided with a substantially parallel handle, and the pair of handle portions are connected by a spring member that can be bent in a “U” shape or a “U” shape in side view. The protrusion main body of the protrusion is formed of any one of a comb tooth, a columnar protrusion, and a brush, and the head is a spherical member having rubber elasticity.

The operation of the present invention will be described below. For example, when used for massage of the scalp, the respective projection surfaces (the surfaces on which the projections are formed) of the pair of massage members are opposed to the scalp. In this state, the head (spherical member) of each projection is brought into contact with the scalp. In this state, the pair of massage members swing in synchronization with their intermediate line. At this time, if the projection surfaces of the pair of massage members move inward symmetrically so that they approach each other,
The protrusions protruding from the respective protrusion surfaces compress the scalp in the surface direction (rubbing operation). At this time, when the massage member rotates in the swinging inner direction, the claw supports and prevents the soft head (spherical member) from protruding outward and deforming. Good massage can be performed by ensuring contact. The skin grip force of the spherical member is enhanced, and the scalp can be moved strongly.

On the other hand, when the pair of massage members move symmetrically so that the protruding surfaces move away from each other, the compression along the surface direction of the scalp is released, and the scalp returns to the original state. When the massage device is moved (along the scalp) in the surface direction of the scalp while keeping the massage device in contact with the scalp, the entire scalp can be rubbed while performing the massaging operation, and a high massage effect can be obtained with a feeling of exhilaration. Can be. Instead of providing the claw portion, at least the distal end portion of the projection main body may have a flat shape, and a head portion made of a soft material may be provided at least in the swinging inner direction of the flat portion.

As the main body of the protrusion, any one of a comb tooth, a columnar protrusion, and a brush can be used, and a head having a rubber elasticity can be used.
As a result, since the coefficient of friction is larger than that of polyethylene or the like, the head of the projection can grip the scalp well and can rub the entire scalp while repeatedly compressing in the surface direction,
A high massage effect can be obtained with a refreshing feeling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The present invention is not limited to the embodiments described below, but includes modifications such as design changes without departing from the scope of the claims. (First Embodiment) FIGS. 1A and 1B show a first embodiment of a massage device according to the present invention. FIG.
In (a) and (b), this massage device 10
A handle 2 extends from one side of the base 1 having a substantially rectangular box shape, and a pair of two massage members 1 is provided inside the opening of the base 1.
1a and 11b are stored in a parallel state. Further, between the massage members 11a and 11b and the handle portion 2, a swinging means 15 described later is provided.

Two pairs of massage members 11a and 11b
Are oscillating shafts 16 and 1 passing through the center in the respective longitudinal directions.
6 and these swing shafts 16 are arranged in parallel so as to be parallel to each other. Both ends of the swing shafts 16 are rotatably supported on the side walls of the base 1, respectively.

The respective massage members 11a, 11b
Has rectangular projection surfaces 12a and 12b that face the skin when used. The protruding surfaces 12a, 12
b protrude from the b. Each of the protrusions 13, 13,... is made of a hard polyethylene main body 13a and a silicone rubber attached to the tip of the main body 13a. (Soft material) head (spherical member) 1
4 In addition, the protrusion main body is not limited to the comb teeth,
The brush may be provided radially, or a columnar projection whose diameter gradually decreases toward the tip may be integrally provided on the projection surface.

[0015] When a brush is used, the hair can be combed and trimmed for purposes other than massage, and there is an advantage that one hair can be used for multiple purposes by applying various hair materials. When using columnar projections, the tip of the columnar projections is made of polyethylene, so the coefficient of friction is small and it is slippery, but because it has a small diameter and the contact area with the scalp is small,
The bite into the scalp becomes deep for a certain pressing force, and an appropriate grip force is obtained. Therefore, when the massage member is rocked, the amount of compression movement and the amount of slip in the plane direction of the scalp are balanced, and a so-called kneading effect appears. In addition, since the tip of the scalp slides deeply into the scalp, a scratching effect appears and itching can be eliminated.

As a feature of this embodiment, as shown in FIGS. 2 and 3A, the tip of the projection main body 13a of the projection 13 is moved when the paired massage members 11a and 11b are swung with each other. The claws 13b are formed in the outward directions. The spherical member 14 is mounted in the concave portion formed by the claw portion 13b. As a result, the spherical member 14 is biased toward the tip of the projection main body 13a in the swinging inner direction (the direction of arrows A and B in FIG. 2). Is provided. Note that, in this example, the claw portion 13b is substantially 90 degrees in the circumferential direction of the spherical member 14.
It is provided every degree, but it is not limited to this, 45 degrees ~
A range of 100 degrees is preferred. In FIGS. 1 and 2, reference symbol C indicates an intermediate line between the pair of massage members 11a and 11b.

The projection body 13a has a claw portion 13b and a head 14 for increasing a contact area with the head 14.
It has a biting portion 13c that cuts into the hole. In addition, as an example of a method of attaching the head 14 to the projection main body 13a, the following method is exemplified. First, the projection body 13a
After the injection molding, the spherical member 14 is continuously injection-molded. As shown in FIG.
After the protrusion main body 13a and the spherical member 14 are separately injection-molded, they are physically connected. That is, a ring-shaped groove 13d (locking portion) is formed at the tip of the projection main body 13, while a concave portion is formed in the spherical member 14 so as to fit into the locking portion, and these are fitted. Undercut fitting that joins by mating. Further, a method of fixing the spherical member to the protrusion main body using an adhesive such as an epoxy-based, urethane-based, or rubber-based cyanoacrylate-based adhesive. Then, the tip of the projection main body is immersed in a resin dissolved in a solvent and pulled up, thereby adhering the resin to be a spherical member to the tip of the projection main body and evaporating the solvent of the resin.

The projection body 13a and the spherical member 14 are formed of a hard material and a soft material, respectively. As a specific combination, in addition to the hard plastic (polyethylene, polyester, etc.) and silicone rubber of the present example, a metal and a soft plastic are used. , Hard plastics and elastomers, wood and soft plastics, and the like.

The swing means 15 is configured as follows. That is, the adjacent massage members 11a, 11
Gears 17 and 17 are coaxially mounted on the handle portions of the swing shafts 16 and 16 of b. A rod-shaped rack member 18a having teeth engaged with the gears 17 and 17 carved on both sides is inserted between the gears 17, 17. The rack member 18a can reciprocate in a direction perpendicular to the plane including the swing shafts 16, 16, and the gears 17, 17 and the rack member 18a form a so-called rack and pinion mechanism. doing.

A bar-shaped spring member 3 extends in the direction of the base 1 from the terminal portion 2a of the handle portion 2 with a gap from the handle portion 2, and its tip end is connected to one end of the rack member 18a via a pin. Are linked. A finger pad 3 is provided at an intermediate portion of the spring member 3.
a is formed.

The massage device 10 is shown in FIG.
As shown in (b), it can be used for scalp massage. First, grip the handle 2 with your hand, and place your thumb on the spring
And the projection surfaces 12a and 12b are opposed to the scalp. In this state, the spherical member 14 at the tip of each comb tooth 13 is brought into contact with the scalp S, and the finger rest 3a is pressed toward the handle 2 with the thumb.

By this operation, the rack member 18a is
The gears 17 are moved in the depth direction of the base 1 perpendicularly to the plane including both the swing shafts 16, and the gears 17 engaged therewith are rotated in opposite directions. As a result, as shown in FIG. 4A, the protruding surfaces 12a and 12b of the adjacent massage members 11a and 11b swing symmetrically so as to be inward with each other. If the projection surfaces 12a, 12b swing symmetrically inward, the spherical members 14, 14,... At the tips of the comb teeth 13 projecting from the respective projection surfaces 12a, 12b compress the scalp in the surface direction. It becomes (rubbing operation).

Next, when the pressing by the thumb is released, the spring member 3 returns to the original position, and accordingly the rack member 1 is moved.
8a is lifted, and the gears 17 and 17 rotate in opposite directions to each other, and as shown in FIG.
The projection surfaces 12a and 12b of the a and 11b swing symmetrically so that they face outward. When the projection surfaces 12a and 12b swing symmetrically outward, the compression along the surface direction of the scalp is released, and the scalp returns to the original state. At this time, the projection body 1
Since the claw portion 13b of 3a is configured to support only a part of the height of the head 14, the projection body 13b is attached to the scalp S.
a does not touch and does not scratch.

When the massage device 10 is moved while repeatedly pressing and relaxing with the thumb, preferably while keeping the massage device 10 in contact with the scalp, the spherical member 14 is a rubber elastic body,
Since the coefficient of friction is larger than that of polyethylene or the like, the scalp can be gripped well and the entire scalp can be rubbed while repeatedly compressing in the surface direction, so that a refreshing feeling and a high massage effect can be obtained.

When this massage device is used, a spherical member 14, which is a rubber elastic body and has a relatively large friction coefficient, is attached to the tip of the comb teeth 13, and the massage members 11a and 11b are swung. When the comb teeth 13 are turned inward, the claw portions 13b support and prevent the soft spherical member 14 from overhanging and deforming outward, so that the skin grip force of the spherical member 14 is enhanced, With this massage device, scalp movement can be strongly caused. Further, the tip (bite portion) 13c of the projection body 13a
Bite into the spherical member 14 to increase the contact area between them, so that the spherical member 14 is less likely to fall off.

In each of the following embodiments including this embodiment, the tips of the comb teeth 13 are not limited to those shown in FIG. 3 (a) but may be formed as shown in FIG. 3 (b). 13a
Only the claw 13b is formed at the tip of the projection body 13a.
3C, a ring-shaped groove 13d is formed in the biting portion 13c of the projection main body 13a, while a portion other than the claw portion 13b does not bite into the spherical member 14, or as shown in FIG. 14 side, the link-shaped groove 13d
A ring-shaped projection that fits into the projection may be formed. Further, as shown in FIG. 3D, instead of providing a claw portion,
The tip portion 130 of the projection main body may have a flat shape, and a substantially spherical head 140 made of a soft material may be provided in the flattened portion in the swinging inner direction (the direction of arrow A).
In FIG. 3D, a spherical head may be provided so as to be located on both sides of the flat portion in the swing direction.

(Second Embodiment) A massage device 20 according to a second embodiment shown in FIG. 5 has a handle 2 extending from one side of a substantially rectangular box-shaped base 1. A pair of two massage members 41a and 41b are housed inside the opening of. Further, between the massage members 41a and 41b and the handle portion 2, a swinging means 42 described later is provided.

Two massage members 41a, 41b
Are provided in the opening of the base 1 with swing shafts 43, 43 parallel to each other.
Are arranged in parallel. The swing shaft 43 is provided eccentrically inward from the center line of each of the massage members 41a and 41b, and is rotatably supported on the side wall of the base 1.

Each massage member 41a, 41b
Has rectangular projection surfaces 12a and 12b that face the skin when used. The protruding surfaces 12a, 12
b is formed into a convex shape with a convex cross section (see FIG. 6 described later), and a large number of polyethylene comb teeth (projections) 13 are implanted on its surface. Then, in the second to eighth embodiments to be described later, the comb teeth 1
The structure of the third embodiment is the same as that of the first embodiment, and a spherical member 14 made of silicone rubber is mounted on the tip of the comb tooth 13.

The swing means 42 is configured as follows. That is, two adjacent massage members 41
Gears 44, 44 are coaxially mounted on the handle portions of the swing shafts 43, 43 of a and 41b. The teeth engaged with the respective gears 44, 44 are formed on the outer sides of the respective gears 44, 44 so that the gears 44, 44 can reciprocate in a direction perpendicular to the plane including the swing shafts 43, 43. The rack members 45, 45 are provided upright, and a set of the gear 44 and the rack member 45 respectively forms a rack and pinion mechanism. These rack members 45, 45
Are connected to each other by a bar 46 to form a U-shaped member.

From the terminal 2a of the handle 2, a bar-shaped spring member 3 extends in the direction of the base 1 with a gap from the handle 2, and the tip end thereof is turned to a bar 46 connecting the rack member. It is movably connected. A finger contact portion 3a is formed at an intermediate portion of the spring member 3.

When using this massage device 40,
The handle portion 2 is grasped by hand, and the thumb is applied to the finger contact portion 3a of the spring member 3 so that the protruding surfaces 12a and 12b face the scalp.
In this state, the spherical member 14 at the tip of the comb tooth 13 is brought into contact with the scalp, and the finger rest 3a is pressed toward the handle 2 with the thumb.

By this operation, the respective rack members 45, 45 are moved in the depth direction of the base 1 perpendicularly to the plane including both the swing shafts 43, 43, and the gears 4 engaging with the rack members 45, 45 are engaged.
4 and 44 rotate outward from each other. As a result, the protrusion surfaces 1 of the adjacent massage members 41a and 41b
2a, 12b swing symmetrically so that they face outward, and the spherical members 14, 14,... At the tips of the comb teeth 13 projecting from the respective protruding surfaces 12a, 12b extend the scalp in the surface direction. Will be. At this time, since the oscillating shafts 43, 43 are eccentric inward from each other, the projecting surfaces 12a, 12
The amount of movement of the tip of the comb teeth 13 implanted outside b is larger than that of the comb teeth 13 inside.

Next, when the pressing of the thumb is released, the spring member 3
Is restored to the original position, and accordingly, the rack members 45, 4
5, the gears 44, 44 rotate inward each other, and the protruding surfaces 12a,
12b swing symmetrically so that they face each other.
If the protruding surfaces 12a and 12b swing symmetrically inward,
Comb teeth 13 protruding from the respective protruding surfaces 12a, 12b
The spherical members 14, 14,... At the distal end move in the direction of compressing the scalp. Also at this time, the tip 13 of the comb teeth 13 implanted outside the protruding surfaces 12a and 12b has a larger movement amount at the tip end than the inner one.

When the massage device 20 is moved while repeatedly pressing and relaxing with the thumb, preferably while keeping the massage device 20 in contact with the scalp, the amount of movement of the spherical member 14 disposed outside the protruding surfaces 12a and 12b is increased in the first embodiment. Because it is larger than in the case of the form example, the stroke rubbing the scalp becomes longer,
An efficient massage can be performed.

The oscillating means 42 using the rack and pinion mechanism is not limited to the one shown in each of the above-described embodiments, but may be biased inward from the center line of the massage members 41a and 41b as shown in FIG. Oscillating shafts 43 provided centrally
Gears 48, 48 are engaged with each other, and the rack member 49 can reciprocate in a direction perpendicular to a plane including the two swing shafts 43, 43 by engaging with one of the gears 48. It may be attached to the device. Also in this case, if the rack member 49 is reciprocated, the gears 48, 48 rotate in opposite directions, and the massage members 41a, 41b can swing in symmetrical directions.

In the massage apparatus of each of the above embodiments, if the head 14 of the comb teeth 13 is made of polyethylene, the coefficient of friction of polyethylene is smaller than that of silicone rubber and it is slippery, but the diameter is small. In addition, since the contact area with the scalp is small, the bite into the scalp becomes deep for a certain pressing force, and an appropriate grip force can be obtained. Therefore, when swinging the massage member, the amount of compression movement and the amount of slip in the plane direction of the scalp are balanced, so that a so-called kneading effect is obtained. In addition, since the head slides on the scalp in a state of deep penetration into the scalp, a scratching effect appears, and itching can be eliminated.

Next, an experimental example will be described.

[Table 1] First, Table 1 shows the form of the projection (brissle).
As shown in Table 1, the form of the integral hair refers to a hair in which the projection main body and the head are made of the same material, or a hair made of only the projection body (having a diameter of, for example, 1.2 mm). Say. The form of the material for each head means that a spherical member (head) made of a material softer than the protrusion main body is provided at the tip of the protrusion main body without being eccentric. The form of the nail structure is that of each of the above embodiments. That is, a claw portion at the tip of the protruding main body for preventing the soft spherical member from projecting outward and deforming when the massage member swings and the comb teeth rotate inward (FIG. 3A) Reference). As described above, since the claw portion 13b supports the head portion 14 to prevent its deformation, the gripping force of the spherical member 14 on the skin is enhanced, and the scalp can be moved strongly. The diameter of the head 14 is, for example, 2.5 mm.
And 4.0 mm.

[0039]

[Table 2] Table 2 is a table showing the elastic modulus of each part and the skin of the massage device of the present embodiment and the coefficient of friction (static friction) between the head and the skin. The cap-shaped aponeurosis is located between the periosteum and the skin, and the resistance between the spherical member and the periosteum is extremely small.

[Table 3] Table 3 shows each form of the above-mentioned integral hair, material for each head, material for each head and a claw structure, and various diameters of the tip member (φ1.2
mm, φ2.5mm, φ4.0mm)
It is the table | surface which showed the local distortion and the scalp movement amount. That is,
The results of a simulation test performed to examine the relationship between the diameter of the head, the strain into the scalp (local strain), and the amount of scalp expansion and contraction movement (scalp movement) are shown.

As shown in Table 3, the head 14 of the comb teeth 13
The smaller the curvature, the deeper the bite into the scalp when pressed at a constant pressure, the greater the gripping force, and the amount of compression movement in the plane direction of the scalp when the massage member swings (scalp movement ) Increases.

In this test, as shown in FIG. 10, instead of the scalp, a rubber (pseudo scalp) having an elastic modulus (0.1 kg / mm ² ) similar to that of the skin was placed on a metal spherical surface (pseudo skull) 4. 5 was applied to a thickness of 6 mm, and the radius of curvature of the surface was 90 mm. Several kinds of massage instruments having different curvatures of the heads 14 of the comb teeth 13 were pressed against the pseudo scalp 5 with a constant pressure to perform a massage operation. At this time, the spherical diameter of the head 14 (unit: mm), the strain into the scalp (local strain, × 10 ^-2 ), and the amount of compression movement of the scalp (× 1)
0 ^-1 mm) measured with the results shown in Table 3. The measurement point of the amount of compression movement of the scalp is indicated by the symbol M. In FIG. 10, the radius of curvature R ₁ of the massage members 41a, 41b surface of 30 mm, the distance L rocking shaft 43, 43 20 m
m, the radius of curvature L ₂ of the rubber 5 is 90 mm, the length of the comb teeth 13 is 18 mm.

From the analysis results in Table 3, the following matters can be understood. The smaller the bristle tip, the greater the local strain that occurs on the scalp. Even if the single hair has a large hair diameter, the local strain generated on the scalp is large. The fact that the material for each head has a greater kneading effect than that of the unitary hair is related to the friction coefficient of the head (rubber). Regarding the size of the bristle tip diameter, the smaller the diameter, the greater the bite distortion (local distortion) into the scalp, the easier it is to grip, and the greater the amount of scalp movement (rubbing effect). Regarding the comparison between the nail structure and the head-specific material, it is considered that, for example, even with the same hair diameter, the nail structure has a larger local stress on the scalp, easily grips the scalp, and has a larger scalp movement (rubbing effect). From the analysis results up to now, it is effective for the brush form to have a proper grip feeling when rubbing and a nail structure having a large scalp movement (rubbing effect).

More specifically, from the results in Table 3, the smaller the curvature of the head of the protrusion, the deeper the bite into the scalp when pressed at a constant pressure, the greater the gripping force, and the more the massage member is moved. It can be seen that the amount of compression movement in the plane direction of the scalp when swinging is increased, and the massage effect is enhanced. However, if the curvature is extremely small, the user will feel pain during use. It is preferable that the local distortion is appropriate and the scalp movement amount (rubbing effect) is large. From this viewpoint, it is preferable that the curvature of the head 14 be in the range of 1.2 mm to 4.0 mm. If the curvature exceeds 4.0 mm, the bite into the scalp becomes shallow and slips easily on the scalp, and the compression effect of the scalp becomes thin.

As described above, from the results in Table 3, the head 14
It can be seen that, when the diameter of the increases, the bite distortion into the skin decreases and the amount of scalp compression movement decreases. Also, when the diameter of the tip spherical surface is 2.5 mm or 4.0 mm, when the claw portion 13b is formed on the comb teeth 13, the amount of scalp compression movement becomes larger, that is, the claw in FIG. It can be seen that the structure of the structure has a further improved massage effect than that of FIG.

(Third Embodiment) A massage device 40 according to a third embodiment shown in FIG. 7 is the same as that shown in the first embodiment except that the swinging means is a U-shaped coupling device. Is the same as A pair of two massage members 11a and 11b in the massage device 40 are arranged side by side inside the opening of the base 1 with swing shafts 16 and 16 parallel to each other.
The oscillating shafts 16 and 16 are respectively
a, side wall of base 1 through central part of 11b (not shown)
It is rotatably supported by the shaft.

On the opposite sides of the massage members 11a and 11b, the wing tips 51b of a connecting plate 51 made of, for example, polypropylene and formed into a U-shape in a side view are formed.
51b are respectively joined. In addition, as a material of the connecting plate 51, besides polypropylene, plastic such as U polymer (polyarylate) or steel can be used. A central portion 51a of the connecting plate 51 is joined to one end of a swinging rod 52 which can reciprocate in a direction perpendicular to a plane including both the swinging shafts 16 and 16. This swinging rod 5
The other end of 2 is joined to the tip of a rod-shaped spring member 3 extending from the terminal of the handle (not shown) toward the base 1 with a gap from the handle.

When the massage device 50 is used, the handle is gripped by hand, the spherical member 14 at the tip of the comb tooth 13 is brought into contact with the scalp, and the spring member 3 is pressed toward the handle 2 to swing the rocking rod. The reference numeral 52 moves in the depth direction of the base 1, and accordingly, the connecting plate 51 also moves in the same direction. Then, the sides of the massage members 11a, 11b are simultaneously pulled in the depth direction of the base 1, and as a result, the massage members 11a, 11b
b swing symmetrically in a direction in which they face inward. Along with this, the spherical members 14, 14,... At the tips of the comb teeth 13 protruding from the respective protruding surfaces 12a, 12b compress the scalp in the surface direction.

Next, when the pressing of the spring member 3 is released, the spring member 3 returns to the original position, and the swinging rod 52
Is lifted up, and the connecting plate 51 also returns to its original position, so that the massage members 11a and 11b oscillate symmetrically outward, and the compression in the plane direction of the scalp is released, and the scalp returns to the original state. Return.

The curvature of the connecting plate 51 changes with the reciprocating movement of the swinging rod 52. However, since the connecting plate 51 is made of polypropylene and has flexibility, it does not break even if it is repeatedly bent. The swinging means of this embodiment has an advantage that the mechanism is simple and an inexpensive massage device can be obtained.

In each of the above embodiments, the swinging means is driven by manually pressing the spring member 3 extending from the handle 2. However, the method of driving the swinging means is not limited to this. For example,
