てあることを特徴とするボールクラツチの構造。 A driven shaft 13 is attached to the cylindrical boss portion 12a of the drive rotary body 12.
A transmission ball 12c is inserted into the shaft so as to be freely rotatable, and a transmission ball 12c is engaged and held between a recess 13a formed on the outer circumferential surface of the driven shaft 13 and a ball hole 12b formed in the cylindrical boss portion 12a so as to penetrate inside and outside. Then, a ball presser cylinder 14 that can be artificially shifted in the axial direction is fitted around the outer periphery of the cylinder boss portion 12a, and the ball presser cylinder 14 is
A contact surface 14b for abutting and supporting the ball 12c at a position where the ball 12c is inserted between the recess 13a and the ball hole 12b is provided on the inner peripheral portion of the contact surface 14b, and a contact surface 14b for the ball 12c to move outward in the radial direction and come out of the recess 13a. In the structure of the ball clutch, the recessed portions 14a are arranged in parallel in the axial direction, and the transmission state via the balls 12c and the transmission release state are switched by shifting the ball presser cylinder 14. For now 1
4b is formed with a tapered surface 19 that is spaced apart from the axis of the ball presser cylinder 14 toward the recessed portion 14a.
