Claims

[Scope of utility model registration request]

A rotating shaft, a rotating arm rotatably fitted to the rotating shaft, a transmission member fixed to the rotating shaft, and a rotating arm rotatably fitted to the rotating shaft between the transmission member and the rotating arm. an intermediate member; a first torsion coil spring that connects the intermediate member and the rotary arm; a second torsion coil spring that connects the intermediate member and the transmission member by winding in a reverse manner with respect to the first torsion coil spring; a first stopper provided on one of the rotary arm and the intermediate member to stop relative rotation between them due to a first torsion coil spring;
An escape mechanism for a rotary power transmission device, comprising a second stopper that is provided on one of the intermediate member and the transmission member to prevent relative rotation between the intermediate member and the transmission member by a second torsion coil spring.
