Abstract
An overload release clutch to be mounted between rotary drive and driven members includes a recess formed on one member and a hole formed on the other member at a position axially corresponding to the recess, the recess being arcuate in the circumferential direction and extending in the axial direction. A transmission roller having a crowned peripheral surface, extending in the axial direction and having a tapered surface at least one end, is fitted in the hole so as to be rotatable on its axis and movable along the radial direction. The roller is normally urged by pressure means radially inward and engages with the recess for transmitting the rotational movement of the drive member to the driven member. When an overload torque is applied, the pressure means permits the roller to move radially outward to disengage from the recess.
