Abstract
A first opposing portion of the coupling includes first ratchet hook and a second opposing portion of the second rotary body includes a second ratchet hook. One of the third opposing portion of the coupling and the fourth opposing portion of the first rotary body has a cam on an end face thereof and the other one has a cam face on an end face thereof. When the first rotary body rotates in a forward direction, a camming action turns on the transmission of torque. When the first rotary body rotates in a backward direction, the transmission of torque is turned off. A protrusion provided on a portion other than the cam or the cam face of the end face of one of the third opposing portion of the coupling and the fourth opposing portion of the first rotary body comes into contact with a portion other than the cam or the cam face of the end face of the other one of the third opposing portion and the fourth opposing portion while the transmission of torque is turned off.
