Claims

[Scope of utility model registration request]

an endless transmission member that is hooked between the drive source and the transmission rotation member; a drive shaft that fixes the transmission rotation member and transmits the rotation of the drive source; a joint cylinder provided on the shaft end side of the drive shaft; A spring bearing provided in the joint cylinder and transmitting the rotation of the drive shaft to the joint cylinder is provided in the joint cylinder so as to face the member via the spring, and is opposite to the end surface on the spring side. A retaining disk having a plurality of guide pieces formed in the circumferential direction of the side end face, and a driven shaft provided with a pin that is pushed along the guide pieces and engages in a groove between the guide pieces, The guiding piece is formed with an inclined surface that slopes only in one direction toward the groove, and when the pin is pushed along the inclined surface, the pressing force of the pin acts as a component force in a rotating direction, A rotation transmission device characterized in that a portion of the endless transmission member on the upstream side of the transmission rotation member with respect to the rotational direction of the transmission rotation member is slackened so that the locking disk can rotate together with the drive shaft.
