Abstract:
An apparatus for transmitting rotational power from a driving body to a driven body, said apparatus comprising:a resilient member coupled to one of the driving body and the driven body;a deformable member coupled to the other one of the driving body and the driven body, said deformable member being deformable by heat; anda contact member interposed between the resilient member and the deformable member, said contact member having a rigidity greater than that of the deformable member,said resilient member and said contact member being in forcible abutment with each other by means of force exerted by the resilient member, said deformable member and said contact member being in abutment with each other, andsaid resilient member and said contact member frictionally contacting one another to generate the heat that deforms the deformable member when load generated in the driven body is in excess of a predetermined value.
