It can be moved back and forth along.

Next, the engaging pin 28 and the traverse cam shaft 2
A description will be given of a configuration for improving the operability of the oscillating mechanism 20 by increasing the amount of engagement with the second and simultaneously reducing the size of the entire reel.

As shown in FIGS. 2 (a) and 2 (b), the sliding member 24 is integrally formed with a retaining member at the opposite portion 24a. This retaining support portion is provided with an engaging pin 2
When the engaging member 8 is engaged with the traverse camshaft 22, the engaging pin 28 can be supported between the sliding body 24 and the traverse camshaft so as to prevent the engaging pin 28 from coming off.

The retaining support portion applied to the present embodiment accommodates the cylindrical base portion 28a of the engaging pin 28, and is capable of retaining and supporting the base portion 28a.
A receiving hole 40 having a blind hole shape and a circular cross section is formed integrally with the facing portion 24a of the sliding member 24.

More specifically, the receiving hole 40 as a retaining support is formed so as to open only on the side of the facing portion 24a of the sliding member 24. The anti-opposing portion 24b is integrally closed.
In this case, the facing portion 24 a of the sliding body 24 is

When the sliding body 24 is moved back and forth along the traverse camshaft 22, the engaging pin 28 moves along the spiral cam groove 22a formed on the traverse camshaft 22 in the forward and backward paths. The inclination angle changes, and at that time, the engagement pin 28 rotates by a predetermined amount. Therefore, the inner diameter of the housing hole 40 and the engagement pin 2 are set so that the engagement pin 28 can rotate smoothly.
It is preferable that the outer diameters of the base portions 28a of the eighth section 8 are mutually adjusted.

In this embodiment, the outer diameter of the traverse cam shaft 22 is increased in order to increase the amount of engagement between the engagement pin 28 and the traverse cam shaft 22 to improve the operability of the oscillating mechanism 20. The dimensions of the spiral cam groove 2 of the traverse cam shaft 22 are increased in accordance with the enlargement ratio.
The tooth width W1 of the tooth portion 28b of the engaging pin 28 engaging with 2a is enlarged. In this case, in order to maintain the strength and durability of the sliding body 24 in which the accommodation hole 40 for accommodating the base 28a of the engaging pin 28 is formed, and to prevent the overall size of the sliding body 24 from being enlarged, the present embodiment is used. At the engagement pin 28
The tooth width W1 of the tooth portion 28b and the inner peripheral diameter W2 of the housing hole 40 of the sliding member 24 are set so as to satisfy the relationship of W1> W2.

Here, an example of a method of incorporating the oscillating mechanism 20 into the reel body 2 will be described.

First, before inserting the spool shaft 10 into the reel body 2, the sliding member 24 must be
After the base 28a of the engaging pin 28 is inserted into the receiving hole 40 and applied, the teeth 28b of the engaging pin 28 are lightly engaged with the spiral cam groove 22a of the traverse cam shaft 22. At this time, the guide surface 32a of the guide support portion 32 projecting laterally from the sliding member 24 is applied to the contact surface 36a of the main body side support portion 36 projecting from the reel body 2, and is projected downward from the sliding member 24. The fitting groove 34a of the fitting guide 34 is fitted to a guide shaft 38 provided on the reel body 2.

Next, the spool shaft 10 is inserted into the reel body 2. At this time, the rear end of the spool shaft 10 is
By inserting a set screw 30 from the opposite side 24b of the sliding body 24 in this state, the sliding body 24 is fixed to the rear end of the spool shaft 10.

As a result of this process, the engagement pin 28
The helical cam groove 2 of the traverse cam shaft 22 is held in a state where the base 28a is supported by the accommodation hole 40 so as not to come off.
2a is firmly engaged.

Thereafter, the cover 44 (FIG.
By mounting the oscillating mechanism 20, the oscillating mechanism 20 is housed in the reel body 2 while being shielded from the outside by the cover 44.

Then, actually, the oscillating mechanism 20
Is operated, the sliding body 24 moves back and forth along the traverse cam shaft 22 while being guided by the two portions of the main body side support portion 36 and the guide shaft 38. As a result, the slide 24
Can be moved back and forth without rattling.

As described above, according to the present embodiment, the tooth width W1 of the tooth portion 28b of the engaging pin 28 is enlarged in accordance with the enlargement ratio of the outer diameter of the traverse cam shaft 22, so that the engaging pin 28
The operability of the oscillating mechanism 20 can be improved by increasing the amount of engagement between the oscillating mechanism 20 and the traverse cam shaft 22. At the same time, the tooth width W1 of the tooth portion 28b of the engagement pin 28 and the inner peripheral diameter W2 of the accommodation hole 40 that accommodates the base 28a of the engagement pin 28 are set so as to satisfy the relationship of W1> W2. The strength and durability of the sliding body 24 can be maintained without increasing the size of the entire sliding body 24, and as a result, the whole reel can be reduced in size.

That is, in the limited space in the reel body 2, the size of the oscillating mechanism 20 (particularly, the size of the sliding body 24) is reduced while the engagement pin 28 and the traverse cam shaft 22 are simultaneously connected. Since the engagement amount (the radius of curvature of the tooth portion 28b of the engagement pin 28 engaged with the traverse camshaft 22) can be increased, both the rotation of the traverse camshaft 22 and the slidability of the engagement pin 28 are improved. It can be improved. As a result, it is possible to stably and smoothly move the sliding body 24 back and forth along the traverse cam shaft 22 while preventing the engagement pin 28 and the traverse cam shaft 22 from being hit one side or generating abnormal noise. It becomes.

According to the present embodiment, the sliding member 24
Is not formed so as to cover the entire circumference of the traverse cam shaft 22, but is formed integrally with an opposing portion 24 a that faces a part of the entire circumference of the traverse cam shaft 22. That is, since the sliding body 24 has a wide opening facing the traverse camshaft 22, the weight of the sliding body 24 can be reduced, and as a result, the operability of fishing can be further improved. It becomes possible.

The present invention is not limited to the configuration of the above-described embodiment, but can be variously modified as follows.
