ABSTRACT:
A mechanism for detecting stopping of rotation of a normally rotating member which mechanism can be minimized in its axial direction and reduced in production cost. The mechanism comprises a normally rotating member normally rotating in one direction around a fixed axis, and a detecting member for detecting stopping of rotation of the normally rotating member. One of the two members has a resilient contacting portion for resiliently contacting and fitting with the other member under a radially acting resilient force of the same thereby to produce a contact pressure between the two members. The detecting member is urged in a direction by the normally rotating member when the normally rotating member is rotating, and the detecting member detects stopping of rotation of the normally rotating member from disappearance of the urging force by the normally rotating member.
