Abstract

A torque limiting device includes a first rotating member, a second rotating member, an engagement member, and a biasing member. The biasing member biases the engagement member from a first rotating member toward a second rotating member. The biasing member biases the engagement member in a direction inclined relative to a radial direction of the first rotating member.

Claims

1. A torque limiting device for a fishing reel, comprising:

a first rotating member disposed so as to be rotatable relative to a reel body;

a second rotating member disposed so as to be rotatable relative to the first rotating member radially outside of the first rotating member, and having a recess on an inner circumferential portion thereof;

an engagement member disposed on the first rotating member and configured to cause the second rotating member to rotate integrally with the first rotating member when engaged with the recess; and

a biasing member configured to bias the engagement member from the first rotating member to the second rotating member,

the biasing member biasing the engagement member in a direction inclined relative to a radial direction of the first rotating member.

2. The torque limiting device for a fishing reel according to claim 1, wherein

when one of the first rotating member or the second rotating member rotates in a line winding direction, and an other of the second rotating member or the first rotating member limits the rotation of the one of the first rotating member or the second rotating member, the biasing member biases the engagement member so as to be inclined relative to the radial direction to increase the limiting torque.

3. The torque limiting device for a fishing reel according to claim 1, wherein

the recess includes a pressing surface that is pressed by the engagement member when the first rotating member and the second rotating member integrally rotate, and a sliding surface on which the engagement member slides when the first rotating member and the second rotating member rotate relative to each other.

4. A spinning reel, comprising:

a reel body including a rotatable handle;

a spool around which a fishing line is configured to be wound by rotation of the handle;

a reciprocating mechanism having a slider configured to move the spool back and forth in a spool shaft direction to evenly wind the fishing line around the spool; and

the torque limiting device according to claim 1 disposed between the handle and the slider.

5. The spinning reel according to claim 4, wherein

the first rotating member of the torque limiting device has an engagement portion that engages with the slider, and

the second rotating member of the torque limiting device has a gear portion to which torque from a drive shaft is transmitted.

6. The torque limiting device for a fishing reel according to claim 1, wherein

the second rotating member includes teeth to mesh with a gear portion of a drive shaft.

7. The torque limiting device for a fishing reel according to claim 1, wherein

the biasing member is disposed in the first rotating member.
