Claims

[Scope of utility model registration request]

A first rotating shaft and a second rotating shaft are arranged inside the case in parallel with each other, a gear is fixed to the first rotating shaft, and a sliding gear is meshed with the gear to transmit rotation. is fitted into the second rotating shaft so as to be slidable in the axial direction, and a spline is formed on the inner circumferential surface of the fitting hole of the sliding gear and the outer circumferential surface of the second rotating shaft;
A pressing spring is attached to one end surface of the sliding gear to constantly press the splines in a direction in which they fit together, a camshaft is rotatably inserted into the case, and a rotary arm is attached to the inner end of the case of the camshaft. a rotating grip is provided at the outer end of the case of the camshaft, and rotation of the rotating grip causes the rotating arm to press the sliding gear against the spring to disengage the spline. A clutch mechanism in a gear transmission characterized by:
