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.
