Abstract
A bidirectional torque limier, which allows setting a slip torque for a case of inputting rotation from a driving part to be smaller than a slip torque for a case of inputting rotation from a driven part. The force of an external coil spring (42) to clamp an outer race (8) is set smaller than the force of an internal coil spring (48) to clamp an inner race (10), so that the external coil spring (42) increases its diameter to slip with respect to the outer race (8) when a rotation torque is applied from the driving part, while the internal coil spring (48) increases its diameter to slip with respect to the inner race (10) when a rotation torque is applied from the driven part.
