Title:
CLUTCH UNIT AND MOTOR
Document Type and Number:
Japanese Patent JP2015163803
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a clutch unit which prevents an output shaft from unnecessarily rotating at high speed.SOLUTION: A clutch unit 8 includes: an input member (a rotation transmission shaft 7); a driven rotary shaft (an output shaft 9); a cylindrical fixing member (a clutch ring 88) provided at the outer peripheral side of the driven rotary shaft 9; engagement elements (cylindrical members 86) provided between the cylindrical fixing member and the driven rotary shaft; a retainer 87 which integrally rotates with the input member and retains the engagement elements; and engagement parts 9c and 82c which abut on and engage with each other when the input member and the driven rotary shalt are rotated relatively by a prescribed angle. When the driven rotary shaft is rotated with respect to the input member at a relatively fast rotational speed, the engagement elements are positioned in a wedge-shaped space comprising an inclined part provided in an outer periphery of the driven rotary shaft and an inner periphery of the cylindrical fixing member, and the input member and the driven rotary shaft are synchronously rotated by locking the cylindrical fixing member and the driven rotary shaft by the engagement elements 86.
