The plural pawl-side cam surfaces or the cam surface is configured in a manner that the plural pawl-side cam surfaces and the cam surface are in contact with each other when the external teeth and the internal teeth are in an engaged state and in a manner that clearances generated between each of the plural pawl-side cam surfaces and the cam surface in the radial direction are all uniform.
