ABSTRACT:
In an overload clutch for shutting off torque transmission when an overload is encountered in an driven part, a pressure member is formed with a tapered surface so that a ball may be held by the tapered surface, the outer surface of the driving member and the end surface of a ring member axially urged by a spring while torque is transmitted. An annular groove is formed on the outer surface of the driving member such that the ball falls into the groove when torque transmission is shut off due to an overload such that the urging force will not act on the pressure member. Restoration to the torque-transmitting operation may be effected by moving the pressure member in the reverse direction.
