Abstract

The invention provides a torque limiting device of a fishing reel and the fishing reel. The torque limiting device (70) is used for limiting the torque between the driving shaft (30) (one example of the 1 st rotating component) and the rotating component (52) (one example of the 2 nd rotating component). The torque limiting device (70) has an engagement recess (72), an engagement member (73), and a biasing member (74). The engagement recess (72) is formed in the inner peripheral surface of the rotary member (52). The engagement member (73) is disposed on the drive shaft (30) so as to advance and retreat toward the rotation member. The engagement member has a head portion (73 a) engageable with the engagement recess. The urging member (74) urges the engagement member (73) toward the rotation member (52). The head part (73 a) of the engagement member has a linear part (73 c) extending linearly along the rotation axis direction of the drive shaft at the tip end. Accordingly, the durability of the torque limiter device is improved in the torque limiter device of the fishing reel and the fishing reel.

Description

Torque limiting device for fishing reel and fishing reel Technical Field The present invention relates to a torque limiter for a fishing reel and a fishing reel. Background Conventionally, a fishing reel having a torque limiter is known. For example, the torque limiter disclosed in patent document 1 is used to limit torque between a handle shaft and a gear supported by the handle shaft. The torque limiter has an engagement member and a biasing member. The tip of the engaging member engages with the inner peripheral surface of the gear. The urging member urges the engagement member toward the inner peripheral surface of the gear. [ Prior Art literature ] [ Patent literature ] Patent document 1 Japanese patent application laid-open No. 5912371 Disclosure of Invention [ Problem to be solved by the invention ] With respect to such torque limiting devices, it is desirable to improve durability (durability) thereof. The invention aims to improve the durability of a torque limiting device in a fishing reel and the durability of the torque limiting device in the fishing reel. [ Solution for solving the problems ] The torque limiter for fishing reel according to the present invention is for limiting the torque between a 1 st rotation member and a2 nd rotation member, wherein the 1 st rotation member is rotatably disposed on a reel body, and the 2 nd rotation member is rotatably disposed on the outer peripheral side of the 1 st rotation member about a rotation axis (axis of rotation) of the 1 st rotation member. The torque limiter has an engagement recess, an engagement member, and a biasing member. The engagement recess is formed in the inner peripheral surface of the 2 nd rotary member. The engaging member is disposed on the 1 st rotation member so as to advance and retract toward the 2 nd rotation member. The engagement member has a head portion engageable with the engagement recess. The urging member urges the engagement member toward the 2 nd rotation member. The head of the engaging member has a linear portion at a distal end thereof, the linear portion extending linearly along the rotation axis direction of the 1 st rotation member. In this torque limiter for a fishing reel, since the head portion has a straight portion at the tip end, the engaging member is in line contact with the engaging recess. Accordingly, the stress can be dispersed as compared with the case where the engaging member is in point contact with the engaging recess, and thus the durability of the engaging member and the engaging recess is improved. As a result, the durability of the torque limiter device can be improved. In the engaging member, at least the head portion may be made of resin. In this case, the durability of the engaging member and the engaging recess is improved as compared with the case where the engaging member is in point contact with the engaging recess, and therefore, at least a part of the engaging member can be made into a resin, and the torque limiter can be made lightweight. The head portion may have a pair of inclined portions connected to the straight portion, and at least a portion of the inclined portions may be in contact with the engagement recess. The pair of inclined portions may be formed so as to expand in the rotation axis direction of the 1 st rotation member as approaching the linear portion. In this case, both improvement in durability and weight reduction of the engaging member can be achieved. A fishing reel according to another aspect of the present invention includes a reel body, a 1 st rotational member rotatably disposed on the reel body, a 2 nd rotational member rotatably disposed on an outer peripheral side of the 1 st rotational member about a rotational axis of the 1 st rotational member, and the torque limiter for limiting torque between the 1 st rotational member and the 2 nd rotational member. In this fishing reel, since the head portion of the engaging member has a straight portion at the tip end, the engaging member is in line contact with the engaging recess. Accordingly, the stress can be dispersed as compared with the case where the engaging member is in point contact with the engaging recess, and thus the durability of the engaging member and the engaging recess is improved. As a result, the durability of the torque limiter device can be improved. [ Effect of the invention ] According to the present invention, in a torque limiter for a fishing reel and a fishing reel, durability of the torque limiter can be improved.
