Description

The present invention relates to a fishing reel and a reciprocating mechanism for a fishing reel, and particularly to a reciprocating mechanism that is driven in conjunction with a spool of a fishing reel.

A typical fishing reel is equipped with a reciprocating mechanism (level wind mechanism) for evenly winding the fishing line around the spool. A typical reciprocating mechanism includes a worm shaft having a spiral groove, an engaging member, and a sliding member. The engagement member engages with the helical groove of the worm shaft. As the worm shaft rotates, the engaging member reciprocates along the worm shaft. The sliding member holds the engagement member and moves back and forth integrally with the engagement member (for example, see Patent Document 1).

In such a mechanism, fishing line guided by a reciprocating sliding member is wound uniformly onto a spool. Therefore, it is necessary to suppress rattling when the engaging member reciprocates along the worm shaft.

In the reciprocating mechanism described in Patent Document 1, a holding portion 92 of a lid member 9 having a lid main body portion 91 and a holding portion 92 is connected to the inner circumferential surface of the first through hole 81 and the shaft portion 71 of the engaging member 7. The engaging member 7 is disposed between the first through hole 81 and the outer circumferential surface, and holds the engaging member 7 slidably and rotatably within the first through hole 81.

At this time, by further including the outer cylinder part 922 and the inner cylinder part 923, the holding part 92 can smoothly rotate the inner cylinder part 923 with respect to the outer cylinder part 922, and the engagement member 7 It is said that this suppresses rattling that occurs between the engaging member 7 and the sliding member 8 when they reciprocate along the worm shaft.

However, in the conventional reciprocating mechanism described above, a female screw portion 811 is provided on at least a portion of the inner peripheral surface of the first through hole 81 of the sliding member 8, and at least one portion of the outer peripheral surface of the holding portion 92 of the lid portion 9 is provided with a female screw portion 811. A male threaded portion 921 is provided at the portion. In order to maintain the strength of the threaded part between the male threaded part and the female threaded part, it is necessary to ensure the strength of the male threaded part, but it is necessary to increase the strength of the holding part 92, which is originally preferable to have a thin wall.

Further, in Patent Document 1, the holding part 92 includes an outer cylindrical part 922 and an inner cylindrical part 923, and a male screw part 921 is arranged on the outer peripheral surface of the outer cylindrical part 922. A bearing member has also been proposed. However, in the case of such a structure, when the inner cylinder part 923 is used as a bearing member, the tightening force necessary for fitting is applied to the bearing member while the spiral groove 51 and the engaging claw part 72 are engaged when assembling the reel. It is difficult to apply it to the outer ring, and there is a possibility that it will not result in suitable rattling suppression.

Furthermore, in the case of a reciprocating mechanism linked to a line winding section in which the sliding member is reciprocated not only when winding the fishing line but also when discharging the fishing line, the amount of reciprocating movement of the engaging member relative to the worm shaft also becomes large. Therefore, it is also necessary to reduce the frictional resistance when the engaging member rotates when the engaging member changes direction at the end of the worm shaft.

The present invention has been made in view of the above circumstances, and it suppresses rattling while the engaging member reciprocates along the worm shaft, and also allows the engaging member to change direction at the end of the worm shaft. An object of the present invention is to provide a fishing reel and a reciprocating mechanism for the fishing reel, which can reduce frictional resistance when rotating.

In order to solve the above problems, the present invention employs the following means.
A reciprocating mechanism for a fishing reel according to the present invention includes a worm shaft having a spiral groove on its outer peripheral surface and extending in the axial direction, an engaging member that engages with the spiral groove, and a reciprocating mechanism that accommodates the engaging member.

The guide member 60 is arranged on the outer circumferential side in a state where the worm shaft 51 is accommodated.

The guide member 60 is provided with a window 61 for engaging the engaging member 70 and the spiral groove 52. The window portion 61 is formed along the longitudinal direction of the guide member 60.

The engagement member 70 includes a cylindrical shaft portion 71 and an engagement claw portion 72 that is screwed into the spiral groove 52 . The shaft portion 71 is arranged to extend from the outside of the guide member 60 through the window portion 61 and into the inside of the guide member 60 . The shaft portion 71 further includes a small diameter portion 711 and a large diameter portion 712. An engagement claw portion 72 is connected to an end of the large diameter portion 712 . The engaging claw portion 72 is formed in a substantially C-shape.

The sliding member 80 includes a main body 81 that reciprocates in the axial direction of the worm shaft 51, and a fishing line guide section 82 connected to the main body 81 and from which the fishing line S is let out.

Next, the operation of the fishing reel 1 and the level wind mechanism 50 according to this embodiment will be explained.
First, when winding the fishing line S around the spool 8, the handle 20 of the fishing reel 1 is operated in one direction. At this time, the worm shaft 51 rotates in one direction around the axis via the rotation transmission mechanism 30. With this rotation, the sliding member 80 moves in the axial direction of the worm shaft 51 via the engaging member 70 engaged with the spiral groove 52 .

When the engaging member 70 reaches the end of the worm shaft 51, the engaging member 70 is reversed around the shaft portion 71 in accordance with the spiral groove 52, and moves in the opposite direction along the worm shaft 51. As the sliding member 80 reciprocates along the worm shaft 51, the fishing line S is threaded uniformly over the surface of the spool 8.

When releasing the fishing line S, a clutch (not shown) is operated to disconnect the rotation transmission mechanism 30 and the worm shaft 51 and release the fishing line S. At this time, the worm shaft 51 rotates around the axis in a direction opposite to that during winding. With this rotation, the sliding member 80 moves in the axial direction of the worm shaft 51 via the engaging member 70 engaged with the spiral groove 52 .

When the engaging member 70 reaches the end of the worm shaft 51, the engaging member 70 is reversed around the shaft portion 71 in line with the spiral groove 52, as in the case of winding, and moves in the opposite direction along the worm shaft 51. do. As the sliding member 80 reciprocates along the worm shaft 51, the fishing line S is released from the spool 8.

According to this fishing reel 1 and level wind mechanism 50, since the bearing member 100 is arranged, when the engaging member 70 reaches the end of the worm shaft 51, it can be reversed with less frictional resistance. . Therefore, the fishing line S can be wound and let out smoothly.

At this time, the male threaded portion 87 is disposed on the outer circumferential surface of the housing portion 85, and the female threaded portion 93 is disposed on the inner circumferential surface of the cylindrical portion 92 of the lid member 90. Therefore, the tightening force necessary for fitting the bearing member 100 can be applied after the spiral groove 52 and the engaging claw portion 72 are screwed together. Therefore, rattling when the engaging member 70 moves along the worm shaft 51 can be suppressed, and when the engaging member 70 changes direction at the end of the worm shaft 51, the engaging member 70 Frictional resistance when rotating around the portion 71 can be reduced.

In particular, the bearing member 100 includes two bearings 101 arranged in the axial direction of the shaft portion 71. Therefore, the wobbling of the shaft portion 71 relative to the first through hole 83 can be suppressed more suitably than when the number of bearings 101 is one, and the frictional resistance can be reduced more suitably.

Note that the technical scope of the present invention is not limited to the above-described embodiments, and various changes can be made without departing from the spirit of the present invention.
For example, in this embodiment, the bearing member 100 includes two bearings 101, but the number is not limited to two.
