The following describes in detail the embodiments of the in-hat ventilation device and the hat with ventilation device according to the present invention with reference to the drawings. However, the embodiments described below are subject to various limitations that are technically preferable for implementing the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples.

[Hat body]
First, a hat or helmet, which is a hat body on which the in-hat ventilation device 100 is attached, will be described.
For example, the subject of the in-cap ventilation device 100 is a cap C. For example, as shown in Fig. 12, the cap-type cap C includes a cap body 1 which is the cap body, a brim 2 provided on the front side of the cap body 1, an adjuster 3 provided on the rear side of the cap body 1, and the like.

The subject of the helmet internal ventilation device 100 is a helmet H. For example, as shown in Fig. 13(a) and (b), the helmet H includes a helmet body 1 which is the helmet main body, a brim 2 provided around the helmet body 1, a hammock 4, a headband 5, a chin strap 6, and the like.
The hammock 4 is provided to ensure a certain distance between the hat body 1 and the wearer's head.
The headband 5 and the chin strap 6 are for fixing the helmet H to the head of the wearer. The helmet H is fixed to the head by adjusting the length of the headband 5 and the chin strap 6. The headband 5 is adapted to come into contact with the back of the wearer's head.

(Embodiment 1)
[Hat interior ventilation device]
The inner-cap ventilation device 100 of the first embodiment is used by being attached to a cap-type hat C (see FIG. 12) worn by a user.
1(a), (b), (c), 2 and 3, this cap ventilation device 100 includes a bag-shaped body 10 having an opening 10a that is open at the top, a spacer 20 that is a spacing means at least a part of which is housed in the bag-shaped body 10, mounting means 30 for mounting the bag-shaped body 10 to the cap body 1 so that the opening 10a is located inside the cap body 1, a fan 40 that is a blowing means that is attached to the bag-shaped body 10 and takes in outside air into the bag-shaped body 10 and sends it out to the opening 10a side, and a power supply unit (not shown) that is a power supply means for driving the fan (blower means) 40. Here, a power cable 51 that is a part of the power supply means is illustrated.

[Bag-shaped body]
The bag-like body 10 is a member formed into a bag shape by sewing together two sheets, that is, a first sheet 11 and a second sheet 12 .
The first sheet 11 and the second sheet 12 have, for example, an approximately trapezoidal or triangular shape whose width narrows toward the bottom, and by overlapping these sheets and sewing the peripheral edges of the sheets together without sewing the upper ends of the sheets together, a bag-like body 10 having an opening 10a at the top is formed.
It is preferable to use a fabric material with no or low air permeability for the sheet constituting the bag-shaped body 10. This makes it possible to efficiently blow the air taken into the bag-shaped body 10 by the fan 40 to the opening 10a side without letting it leak out.
In this example, the bag-like body 10 is a member formed by sewing together two sheets, the first sheet 11 and the second sheet 12, but it may be a member formed by folding one long sheet, stacking it, and then sewing together the surface on the side of the first sheet 11 and the surface on the side of the second sheet 12 to form a bag-like body. Also, depending on the sewing method, three or more sheets may be used to form the bag-like body.
When a user wears the hat C to which this bag-like body 10 is attached, the second sheet 12 is located on the side that contacts the human body, and the first sheet 11 is located on the outside with a part of it contacting the inner surface of the hat body 1.
The first sheet 11 is provided with a mounting hole (not shown) for mounting the fan 40, and the fan 40 is attached to the mounting hole.

[fan]
The fan 40 is a blower that blows air into the bag-shaped body 10 .
The fan 40 has a function of taking in air into the bag-shaped body 10 and sending the air out through the opening 10a.
A power supply unit (not shown) is connected to the fan 40 via a power cable 51. The power supply unit may be attached to a desired location by the user, for example, attached to a belt or carried in a pocket. The power supply unit has a built-in battery (e.g., a rechargeable battery).

[spacer]
The spacer 20 is a member for forming a predetermined space between the first sheet 11 and the second sheet 12 .
The spacer 20 is a member having a space formed inside its three-dimensional structure through which air can circulate, for example, as shown in Figures 4(a) to (d), and is housed within the bag-shaped body 10 so as to be approximately 10 cm inside the opening 10a, for example, as shown in Figure 1.
The spacer 20 may be sewn or glued inside the bag 10, but is preferably removable from the bag 10. If the spacer 20 is removable from the bag 10, the bag 10 can be easily washed and kept clean. Of course, when washing the bag 10, the fan 40 is removed from the bag 10.

The structure of the spacer 20 may be any structure that can secure a space between the first sheet 11 and the second sheet 12 for directing the air taken into the bag-shaped body 10 by the fan 40 through the opening 10a into the hat body 1. For example, a spacer structure S as shown in Figures 4(c) and (d) disclosed in Japanese Patent Publication No. 4,067,034 can be used.
Specifically, as shown in Figures 4(c) and (d), the spacer structure S includes a frame-shaped portion S11, four pillar portions S12 each having one end connected to the frame-shaped portion S11 and formed to stand up from the frame-shaped portion S11, a convex portion S1 having a connecting surface portion S13 connecting the other ends of the four pillar portions S12, and a flexible connecting portion S2 connecting the frame-shaped portions S11 of adjacent convex portions S1.
This spacer structure S is configured to have a certain degree of flexibility by forming the flexible connecting portion S2 in a strip shape thinner than the frame portion S11, making it easier to bend at the flexible connecting portion S2.
With such a spacer structure S, the number of convex portions S1 connected by the flexible connecting portions S2 can be changed to form a spacer 20 of any size and shape.
The material for forming the spacer 20 may be any material that has sufficient strength to prevent the spacer structure S from losing its three-dimensional structure, such as by being crushed. It is preferable to use a material that has a certain degree of strength but is not too hard. For example, polyethylene (PE) or a more flexible elastomer (TPE) can be used, but there is no particular limitation.

[Attachment Means]
The attachment means 30 in the first embodiment is composed of a pair of loop portions 31 provided on both the left and right sides of the bag-shaped body 10, and a belt member 32 that is passed through each of the loop portions 31 when in use.
The loop portion 31 is formed, for example, by sewing both ends of a string or a thin string-like sheet material to the bag-like body 10. The loop portion 31 is provided at a position near the center of the bag-like body 10 in the up-down direction.
The belt member 32 is, for example, a long, thin sheet-like member having a length of about 6 to 10 cm, and both ends thereof are provided with fastening parts 32a for joining the ends together.
For example, one fastening portion 32a of the belt member 32 is a male hook-and-loop fastener (side A of the hook-and-loop fastener), and the other fastening portion 32a is a female hook-and-loop fastener (side B of the hook-and-loop fastener).
Then, by overlapping and joining the hook-and-loop fasteners at both ends of the belt member 32, the belt member 32 takes on a ring shape.
Alternatively, one fastening portion 32a of the belt member 32 may be a male snap button, and the other fastening portion 32a may be a female snap button.

[Hat with ventilation system]
When attaching such an in-hat ventilation device 100 to the hat body 1 of the hat C, for example, as shown in Figures 2 and 3, the belt member 32 passed through the loop portion 31 is passed through the adjuster 3 of the hat C, and the fastening portions 32a at both ends of the belt member 32 are joined together to form the belt member 32 into a ring shape, thereby connecting the belt member 32 to the adjuster 3.
In this way, the bag-shaped body 10 is attached so as to be positioned on the back side of the head of the user wearing the hat body 1 (hat C).
At this time, the upper part of the bag-like body 10 is inserted into the cap body 1 so that the opening 10a of the bag-like body 10 is located inside the cap body 1. It is preferable that the length by which the upper part of the bag-like body 10 is inserted into the cap body 1 is 5 cm or more.
In this manner, the in-cap ventilation device 100 can be attached to the cap body 1 of the cap C.
The hat C to which this hat body ventilation device 100 is attached is used as a hat body with a ventilation device.

When a user wears the hat body 1 (hat C) to which the bag-shaped body 10 is attached by the attachment means 30 (loop portion 31, belt member 32), the spacer 20 ensures that a space A is created for air taken into the bag-shaped body 10 by the fan 40 to be sent into the hat body 1 from the opening 10a.
In particular, the lower end of the spacer 20 housed in the bag-like body 10 is designed to be at least at the lower end of the rear surface of the hat body 1 when the user wears the hat C equipped with the in-hat ventilation device 100, so that the bag-like body 10 is not crushed by the edge of the hat body 1, and the spacer 20 suitably secures a space A for the fan 40 on the outside of the hat body 1 to send the air taken into the bag-like body 10 into the hat body 1. Here, the spacer 20 is designed to be at the outer side of the hat body 1 when the user wears the hat C equipped with the in-hat ventilation device 100.
When the bag-shaped body 10 is viewed in cross section in the range from the attachment position of the fan 40 to the opening 10a, the opening area of the internal space is preferably 3 ^cm2 or more.

With such an internal hat ventilation device 100 or a hat body with a ventilation device in which the internal hat ventilation device 100 is attached to a hat C, the air taken into the bag-shaped body 10 by the fan 40 can be sent into the hat body 1, generating an air flow on the surface of the user's head, thereby replacing the air inside the hat body 1 and eliminating stuffiness, allowing the user to feel cool.
In particular, this in-cap ventilation device 100 can be attached to any cap C that is equipped with an adjuster 3, making it possible for the user to use any cap C that the user desires, such as any cap C that the user owns, as a cap body with a ventilation device.
In other words, by using this hat body ventilation device 100, the hat C that the user likes to wear can be used as a hat body with a ventilation device, so that even users who have been hesitant to wear special hats with fans like those in the prior art can easily use it to feel cool.

The present invention is not limited to the above-described embodiment.
For example, as shown in Figures 5(a) and (b), when a user wears the hat body 1 (hat C) to which the bag-shaped body 10 is attached by attachment means 30 (loop portion 31, belt member 32), the upper end of the spacer 20 may be configured to be located outside the opening 10a of the bag-shaped body 10, for example, by 3 cm or more.
With this type of in-hat ventilation device 100, the space A for discharging the air drawn into the bag-shaped body 10 by the fan 40 into the hat body 1 is secured up to near the top of the user's head by the spacer 20, so that an air flow can be generated deep inside the hat body 1, eliminating stuffiness over a wider area.

Furthermore, as shown in Figures 5 (a) and (b), the bag-shaped body 10 may be formed with an outlet hole 12a through which the fan 40 blows out the air taken into the bag-shaped body 10 toward a user wearing the hat body 1 (hat C).
The second sheet 12 of the bag-shaped body 10 is positioned to cover the back of the head and neck of the user wearing the hat body 1 (hat C). Therefore, if an outlet hole 12a is formed in the second sheet 12, the air blown out from the outlet hole 12a can be blown onto the back of the head and neck of the user.
In other words, air is blown onto the back of the head and neck of the user wearing the hat body 1 (hat C), giving the user a feeling of coolness.

Furthermore, the present invention is not limited to the above-described embodiment.
For example, as shown in Figures 6(a) (b) and 7, the in-hat ventilation device 100 may be configured so that when a user wears a hat body 1 (hat C) to which a bag-like body 10 is attached by attachment means 30 (loop portion 31, belt member 32), the bag-like body 10 covers at least the back of the user's head and the opening 10a of the bag-like body 10 is located on the forehead side of the user.
Also, as shown in Figures 6 (a) (b) and 7, the bag-like body 10 may be configured to cover at least the back of the user's head and also cover the sides of the user's head when the user wears the hat body 1 (hat C) to which the bag-like body 10 is attached by attachment means 30 (loop portion 31, belt member 32).
Specifically, the ventilation device 100 may include a bag-shaped body 10 formed to have an approximately cross shape, and a spacer 20 formed for the bag-shaped body 10 and having an approximately cross shape.
The bag-shaped body 10 here has a pair of wing-like portions 10b extending laterally, and the spacer 20 has a protruding portion 21 that is received in the wing-like portions 10b.
The bag-like body 10 having such a shape is arranged so as to cover a wide range of the inner surface of the hat body 1, and can widely cover the user's head.

Here, the substantially cross-shaped spacer 20 will be described.
As shown in FIGS. 8( a ), 8 ( b ), 8 ( c ), and 8 ( d ), the spacer 20 has a protruding portion 21 that is received in the wing-like portion 10 b of the bag-shaped body 10 .
The spacer 20 body and the protruding portion 21 of the spacer 20 have different shapes of the convex portion S1 and the flexible connecting portion S2.

Specifically, the convex portion S1b of the protruding portion 21 of the spacer 20 is formed to be lower than the convex portion S1a of the spacer 20 body.
When a user wears the hat body 1 (hat C) to which the bag-like body 10 is attached by the attachment means 30 (loop portion 31, belt member 32), the convex portion S1b of the protruding portion 21 of the spacer 20, which corresponds to the portion where the bag-like body 10 covers the side of the head, is formed in a relatively low shape, making it possible to make the space on the side of the head narrower than the space formed by the spacer 20 from the occipital side to the forehead side.
In this way, by making the height of the convex portion S1 of the spacer 20 vary in parts, it is possible to adjust the fit between the user's head and the hat body 1 and to adjust the air flow within the hat body 1 depending on the height of the convex portion S1.

In addition, the flexible connection portion S2b of the protruding portion 21 of the spacer 20 and the flexible connection portion S2a of the spacer 20 body are also formed in a greatly curved shape.
When a user wears the hat body 1 (hat C) to which the bag-shaped body 10 is attached by the attachment means 30 (loop portion 31, belt member 32), the flexible connecting portion S2b of the protruding portion 21 of the spacer 20, which corresponds to the portion where the bag-shaped body 10 covers the side of the head, is formed into a relatively large curved shape, making the protruding portion 21 of the spacer 20 more flexible than the main body of the spacer 20 and making it easier to fit the protruding portion 21 of the spacer 20 to the surface of the head.
On the other hand, the spacer 20 body is relatively difficult to bend, but is designed to stabilize its overall shape.
In other words, the portion where the flexible connecting portion S2b is formed in a relatively large curved shape is relatively easy to bend, whereas the portion where the flexible connecting portion S2b is formed in a relatively small curved shape is relatively difficult to bend.
In this way, by making the curved shape of the flexible connecting portion S2 of the spacer 20 partially different, the ease of bending of the spacer 20 can be adjusted according to the curved shape of the flexible connecting portion S2, and the essential parts of the bag-like body 10 in which the spacer 20 is housed can be maintained in a predetermined shape, and the bag-like body 10 in which the spacer 20 is housed can be positioned to fit against the inner surface of the hat body 1.

Note that, here, the spacer 20 having two types of convex portions S1 with different heights and two types of flexible connecting portions S2 with different curved shapes has been described as an example, but it is also possible to design a spacer 20 having three or more types of convex portions S1 with different heights and three or more types of flexible connecting portions S2 with different curved shapes.

At least a portion of the second sheet 12 of the generally cross-shaped bag 10 is made of a breathable sheet material.
In particular, it is preferable that the area of the second sheet 12 that is arranged inside the hat body 1 is formed of a breathable sheet material.
As the breathable sheet material, for example, woven fabric or knitted fabric having fine holes in the weave or stitches of the fabric can be used, and also non-breathable or low-breathable cloth material having countless fine holes formed therein can be used.

In this way, with the in-hat ventilation device 100 having the bag-shaped body 10 having an approximately cross shape that can cover a wide area of the user's head, and the area of the second sheet 12 that is placed within the hat body 1 being formed from a breathable sheet material, the air taken into the inside of the bag-shaped body 10 by the fan 40 can be released toward the user's head through the fine holes in the second sheet 12, thereby generating an air flow on the surface of the user's head and eliminating stuffiness over a wider area.
The breathability of the second sheet 12 is not limited to being the same in each part, and it may be designed so that the breathability varies in parts. For example, a second sheet 12 designed to have higher breathability on the frontal and temporal sides than on the occipital side may be used.
Furthermore, the side of the second sheet 12 on the side of the head may be made of a mesh member, or may be left open in some cases.

In this embodiment, the bag-shaped body 10 is attached to the hat body 1 (hat C) by the attachment means 30 (loop portion 31, belt member 32), but the method of attaching the bag-shaped body 10 is not limited to this.
For example, when attaching the bag-shaped body 10 to a hat C called a simple helmet or the like in which a plastic protective plate (inner cap) is attached to the inside of the hat body 1, the first sheet 11 may be adhered to the protective plate, so that the inside hat ventilation device 100 is attached to the hat C. In this case, the first sheet 11 is made of a material that can be adhered to the protective plate.
When adopting such an adhesive attachment method, it is of course not necessary for the bag-shaped body 10 to have a loop portion 31 or a belt member 32, and adhesive or heat fusion technology can be used as the attachment means.

(Embodiment 2)
Next, a description will be given of a second embodiment of the in-hat ventilation device and the ventilated hat body according to the present invention. Note that the same parts as those in the first embodiment are given the same reference numerals, and only the different parts will be described.

[Hat interior ventilation device]
The internal helmet ventilation device 100 of the second embodiment is used by being attached to a helmet H (see FIG. 13) worn by a user.
As shown in Figures 9(a), (b), (c) and 10(a) and (b), for example, this helmet ventilation device 100 comprises a bag-shaped body 10 having an opening 10a that is open at the top, a spacer 20 which is a spacing means at least a portion of which is contained within the bag-shaped body 10, an attachment means 30 for attaching the bag-shaped body 10 to the helmet body 1 so that the opening 10a is located within the helmet body 1, a fan 40 which is attached to the bag-shaped body 10 and is a blowing means that takes in outside air into the bag-shaped body 10 and sends it out toward the opening 10a, and a power supply unit 50 which is a power supply means for driving the fan (blower means) 40 (see Figure 10(a)).

The power supply fixing clip 52 here is configured to clamp the brim 2 of the helmet H and install the power supply unit 50 at the boundary between the brim 2 of the helmet H and the shell 1.

[spacer]
The spacer 20 is a member for forming a predetermined space between the first sheet 11 and the second sheet 12 .
The spacer 20 is a long rod-shaped member made of a material having a certain degree of flexibility and strength, such as foamed polyethylene, and is housed in the bag-shaped body 10, arranged in a direction extending from the opening 10a toward the mounting position of the fan 40, as shown in Figures 9(a) to 9(c). This long spacer 20 has a length of, for example, about 10 cm, and a thickness of about 5 to 10 mm.
In this embodiment, four spacers 20 are housed within the bag-like body 10 at a predetermined interval, but the number and thickness of the spacers can be arbitrary as long as a predetermined space can be formed within the bag-like body 10.
The spacer 20 may be sewn or glued inside the bag 10, but is preferably removable from the bag 10. If the spacer 20 is removable from the bag 10, the bag 10 can be easily washed and kept clean.

[Attachment Means]
The attachment means 30 in embodiment 2 is composed of a pair of belt-shaped portions 33 provided at the opening 10a (here, on the first sheet 11 side) of the bag-shaped body 10, and a clip portion 34 arranged at the end of the belt-shaped portion 33.
The belt-like portion 33 is, for example, a long and narrow sheet-like member having a length of about 3 to 6 cm, one end of which is sewn to the opening 10 a (first sheet 11 ) of the bag-like body 10 .
The clip portion 34 is a hook- or pinch-shaped member fixed to the other end of the belt-like portion 33, and serves to attach the end of the belt-like portion 33 to any desired location.

[Hat with ventilation system]
When attaching such an in-cap ventilation device 100 to the cap body 1 of the helmet H, for example, as shown in Figures 10(a) and (b), the clip portion 34 at the end of the belt-like portion 33 is attached to the hammock 4 of the helmet H.
At this time, the upper part of the bag-like body 10 is passed between the headband 5 and the hammock 5, and the opening 10a of the bag-like body 10 is positioned inside the hat body 1. It is preferable that the length by which the upper part of the bag-like body 10 is inserted into the hat body 1 is 2 cm or more.
In this way, the bag-shaped body 10 is attached so as to be positioned on the back side of the head of a user wearing the hat body 1 (helmet H).
In this manner, the inner cap ventilation device 100 can be attached to the cap body 1 of the helmet H.
The helmet H equipped with this inner helmet ventilation device 100 is used as a helmet body with a ventilation device.
It is preferable that the upper part of the bag-like body 10 be inserted between the hammock 5 and the hat body 1.

When a user wears the hat body 1 (helmet H) to which the bag-shaped body 10 is attached by the attachment means 30 (strap portion 33, clip portion 34), the spacer 20 ensures that space is provided for the air drawn into the bag-shaped body 10 by the fan 40 to be sent into the hat body 1.
In particular, the lower end of the spacer 20 housed in the bag-like body 10 is designed to be at least at the rear lower end of the cap body 1 when the user wears the helmet H equipped with the internal cap ventilation device 100, so that the bag-like body 10 is not crushed by the edge of the cap body 1, and the spacer 20 is designed to appropriately secure a space for the fan 40 on the outside of the cap body 1 to send the air taken into the bag-like body 10 into the cap body 1. When the bag-like body 10 is viewed in cross section in a range from the mounting position of the fan 40 in the bag-like body 10 to the opening 10a, the opening area of the internal space is preferably ³ cm2 or more. Here, the lower end of the spacer 20 housed in the bag-like body 10 is designed to be at the outer side of the cap body 1 when the user wears the helmet H equipped with the internal cap ventilation device 100.

With such an in-hat ventilation device 100 or a hat body with a ventilation device in which the in-hat ventilation device 100 is attached to a helmet H, the air taken into the bag-shaped body 10 by the fan 40 can be sent into the hat body 1, generating an air flow on the surface of the user's head, thereby replacing the air inside the hat body 1 and eliminating stuffiness, allowing the user to feel cool.
In particular, this helmet body ventilation device 100 can be attached to and used on any ordinary helmet H that is equipped with a hammock 4, making it possible for the user to use the helmet H that he or she normally wears as a helmet body equipped with a ventilation device.
In other words, by using this helmet inner ventilation device 100, the user can use the helmet H of their choice as a helmet body with a ventilation device without having to prepare a new helmet with special specifications, making it easy to use for feeling cool.

In the above embodiment, a long rod-shaped spacer 20 is used as a spacer for the helmet-mounted internal ventilation device 100, but a spacer 20 having the spacer structure S described in embodiment 1 may also be used.
Furthermore, when the upper part of the bag-like body 10 is inserted between the hammock 5 and the hat body 1, if the bag-like body 10 is not crushed by the edge of the hat body 1, it is not necessary to accommodate the spacer 20 in the bag-like body 10. In this case, the first sheet 11 and the second sheet 12 are connected together using a thread having a predetermined length as a spacing means. By connecting the first sheet 11 and the second sheet 12 together with a thread having a predetermined length, it is possible to prevent the opening 10a of the bag-like body 10 from widening too much when the air taken into the bag-like body 10 by the fan 40 is sent into the hat body 1.

The present invention is not limited to the above-described embodiment.
For example, as shown in Figures 11(a) and (b), when an in-cap ventilation device 100 for wearing a helmet is attached to the cap body 1 of a helmet H, the upper part of the bag-shaped body 10 may not be passed between the headband 5 and the hammock 5, but the opening 10a of the bag-shaped body 10 may be positioned inside the cap body 1, and the clip portion 34 at the end of the belt-shaped portion 33 may be attached to the hammock 4 of the helmet H.
When a user wears the helmet H equipped with the in-shell ventilation device 100, the lower end of the spacer 20 contained in the bag-like body 10 is designed to be located at least at the lower end of the rear surface of the shell 1, and the spacer 20 prevents the bag-like body 10 from being crushed by the headband 5, so that space is appropriately secured for the fan 40 on the outside of the shell 1 to send the air it has taken in into the bag-like body 10 into the shell 1.
Even if the in-cap ventilation device 100 is attached to the helmet H in this manner, the air taken into the bag-shaped body 10 by the fan 40 can be sent into the cap body 1, generating an air flow on the surface of the user's head, thereby replacing the air inside the cap body 1 and eliminating stuffiness, allowing the user to feel cool.

As described above, with the in-cap ventilation device 100 of this embodiment and the cap body with ventilation device in which the in-cap ventilation device 100 is attached to the cap body 1, the air taken into the bag-shaped body 10 by the fan 40 can be sent into the cap body 1, generating an air flow on the surface of the user's head, which eliminates stuffiness by replacing the air inside the cap body 1, allowing the user to feel cool.

In the above embodiment, the internal cap ventilation device 100 is described as being attached to a cap-type hat C or helmet H, but the present invention is not limited to this, and the device may be attached to other hats or caps, such as hat-type hats.

In addition, to attach the internal cap ventilation device 100 to the cap C, the attachment means 30 (loop portion 31, belt member 32) is attached to the adjuster 3 of the cap C, and to attach the internal cap ventilation device 100 to the helmet H, the attachment means 30 (belt portion 33, clip portion 34) is attached to the hammock 4 of the helmet H, but the present invention is not limited to this, and the attachment means 30 can be attached to any location on the cap C or helmet H, and the attachment means 30 can be designed according to the attachment location.

In addition, in the above embodiment, the position of the lower end of the spacer 20 is at least at the lower end of the rear surface of the cap body 1, but the position of the lower end of the spacer 20 may be on the outside or inside of the cap body 1 and can be changed as appropriate.

Of course, other specific details of the structure can also be changed as appropriate.
