Abstract
Two-step protruding portions are provided in a cover of a pulley for hooking the cover on the pulley. When a bridging part is broken, a driving-unit-side portion of the bridging part is outwardly displaced in a rotation axis direction of the pulley. The first-step protruding portion of the cover thereby slips out from a hooking state. However, after the driving-unit-side portion mounts on the driven-unit-side portion, no further force acts outwardly in the rotation axis direction. As a result, the second-step protruding portion of the cover is hooked on the pulley, so that the cover can be fixed to the pulley. This results in inhibiting broken bridging parts or dampers from dispersing.
