Abstract
A torque limiter is configured from a ring body and a spring-form part provided in the ring body. The ring body includes a band-form metal plate and is bent approximately into a C-shape along the circumferential direction of a motor shaft and a lock holder. The spring-form part is formed so as to be capable of radial elastic deformation. The spring-form part is configured from main protrusions arranged in a compressed state between the motor shaft and the lock holder, and from sub-protrusions arranged in a non-compressed state. Further, grease is stored in a part or all of the concavities formed by the main protrusions and the sub-protrusions.
