[Prior art]
2. Description of the Related Art A spinning reel reduction gear type oscillating mechanism (an example of a reciprocating device) is known that includes a drive gear that rotates in conjunction with the rotation of a handle, a stepped gear, and a moving means. The stepped gear includes a large-diameter gear that meshes with the drive gear, and a small-diameter gear that is disposed concentrically with the large-diameter gear and rotates integrally with the large-diameter gear. The large-diameter gear and the small-diameter gear are arranged concentrically and are attached to a gear shaft provided on the reel body. The moving means is means for reciprocating the spool by rotation of the driven gear (for example, see Patent Document 1).

In this reciprocating device, when the handle rotates, the drive gear rotates in conjunction with it. When the drive gear rotates, the rotation is transmitted to the large diameter gear of the stepped gear, and the small diameter gear rotates together with the large diameter gear. When the small-diameter gear rotates, the rotation is transmitted to the driven gear, and the spool reciprocates by the moving means.

[Problems to be solved by the invention]
In the conventional reciprocating device, the stepped gear has a large force acting particularly on the large-diameter gear. Therefore, in order to maintain the large-diameter gear with a high support strength, the gear shaft provided on the reel body is formed thick. It is possible. However, when the gear shaft is formed thick, the gear shaft of the small diameter gear arranged concentrically with the large diameter gear is also formed thick. If the gear shaft of the small-diameter gear is formed thick, there is a risk that the root diameter of the small-diameter gear will be insufficient.
[0006]
An object of the present invention is to sufficiently secure the root diameter of a small-diameter gear while maintaining high support strength of the large-diameter gear in a spinning reel reciprocating mechanism.
[0007]
[Means for Solving the Problems]
A spinning reel reciprocating device according to a first aspect of the present invention is a spinning reel reciprocating device that reciprocally moves a spool back and forth in conjunction with rotation of a handle provided on a reel body of the spinning reel. With a gear and a moving means. The drive gear is a gear that rotates in conjunction with the rotation of the handle. The stepped gear includes a large-diameter gear that is at least partially mounted on a large-diameter gear shaft provided on the reel body and meshes with the drive gear, and a small-diameter gear shaft that is provided at the tip of the large-diameter gear shaft and has a smaller diameter than the large-diameter gear shaft. And a small-diameter gear that is disposed concentrically with the large-diameter gear and rotates integrally with the large-diameter gear. The moving means has a driven gear that meshes with the small-diameter gear, and is a means for reciprocating the spool by the rotation of the driven gear. The large-diameter gear shaft is integrally formed with the small-diameter gear shaft and is formed to project inside the rear side wall of the reel body. The axial length of the large-diameter gear shaft is smaller than the axial length of the small-diameter gear shaft and has a large diameter. Less than the axial length of the gear.
[0008]
In this reciprocating device, when the handle rotates, the drive gear rotates in conjunction with it. When the drive gear rotates, the rotation is transmitted to the large diameter gear of the stepped gear, and the small diameter gear rotates together with the large diameter gear. When the small-diameter gear rotates, the rotation is transmitted to the driven gear, and the spool reciprocates by the moving means. The large-diameter gear is attached to the large-diameter gear shaft, and the small-diameter gear is attached to the small-diameter gear shaft having a smaller diameter than the large-diameter gear shaft. Here, since the large-diameter gear is at least partially mounted on the large-diameter gear shaft, the support strength of the large-diameter gear can be maintained high. Furthermore, since the small-diameter gear is mounted on the small-diameter gear shaft having a smaller diameter than that of the large-diameter gear shaft, the root diameter of the small-diameter gear can be sufficiently secured. Further, it is easy to form the large diameter gear shaft and the small diameter gear shaft, and the strength can be maintained relatively high. Furthermore, it becomes easy to mount the small-diameter gear.

The axial length C of the large diameter gear shaft 18a is smaller than the axial length D of the small diameter gear shaft 18b. The large diameter gear 19 is attached to the entire large diameter gear shaft 18a and a part of the small diameter gear shaft 18b with a margin of length E. For this reason, since the small diameter gear 20 is attached to a portion excluding the length E of the small diameter gear shaft 18b, the bottom surface of the small diameter gear 20 can be lengthened outward in the axial direction by the length E. Therefore, since the root diameter of the small diameter gear 20 can be sufficiently secured, the strength of the small diameter gear 20 can be maintained high.
[0033]
A separate cam pin 16 a protruding toward the slider 22 is caulked and fixed to the side surface of the driven gear 16 as shown in an enlarged view in FIGS. 7 and 8. As shown in FIG. 7, the tip of the cam pin 16a is disposed so as to protrude outward from the root circle 16b, so that the sliding stroke can be increased while maintaining the gear diameter 16c. The driven gear 16 includes a boss portion 16d having a shaft support hole provided at the center of the driven gear 16, and a main body portion 16e having a plurality of tooth portions provided on the outer periphery of the boss portion 16d. Have. The axial length F of the boss portion 16d is longer than the axial length G (the tooth width of the driven gear 16) of the main body portion 16e, as shown in FIG.
[0034]
The slider 22 is supported by the main body member 2a so as to be movable back and forth. The slider 22 is connected to the rear end of the spool shaft 15 so as not to rotate but to move in the axial direction. A long cam groove 22a is formed on the side surface of the slider 22 facing the driven gear 16 in the vertical direction. A cam pin 16a is engaged with the cam groove 22a. The length of the cam groove 22a is slightly larger than the rotation diameter of the cam pin 16a.
[0035]
In the reduction gear type oscillating mechanism 6 having such a configuration, when the master gear shaft 10 rotates, the driven gear 16 rotates through the stepped gear 13 and the cam pin 16a rotates. When the cam pin 16a rotates, the slider 22 with the cam pin 16a engaged with the cam groove 22a moves back and forth to move the spool 4 back and forth.
[0036]
In the spinning reel having such a configuration, the large-diameter gear 19 is mounted on the large-diameter gear shaft 18a having a larger diameter than the small-diameter gear shaft 18b, so that the support strength of the large-diameter gear 19 can be maintained high. Further, since the small diameter gear 20 is mounted on the small diameter gear shaft 18b having a smaller diameter than the large diameter gear shaft 18a, the root diameter of the small diameter gear 20 can be sufficiently secured.
