Abstract: A small and compact rotation transmitter includes a torque limiter and an angular position holding apparatus. An outer race member is installed in a housing, and a coil spring is mounted on the outer peripheral surface thereof. Inside the outer race member, an internal space is formed, and an inner race member is installed concentrically with the outer race member. In the annular space between the outer and inner race members, a thin-plate elastic piece is pressed against the outer and inner race members, and either the outer or inner race member is connected to an input-side device while the other is connected to an output-side device. Even without rotation torque, the position of the output-side device is held by the coil spring. When the rotation torque from the input-side device becomes excessive, slippage occurs on the thin-plate elastic piece, whereby the outer and inner race members are disconnected.

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.
