A force (direction c) is applied to the pawl 6 to elastically deform the pawl 6 beyond the end surface of the idle lever shaft 3. At this time, the idle lever shaft 3 prevents the U-shaped bearing portion from coming off from the groove portion (d.
Direction), the idle lever shaft 3 can be removed from the bearing portion (direction d).
