Abstract
A support structure for supporting a brake, as a frictional coupling device, includes a snap ring, a friction plate, and a back plate. The snap ring fits in a groove that extends in a circle. The back plate is disposed between the friction plate and the snap ring. The back plate is pressed against the snap ring. The snap ring has a first end face that faces the back plate and a second end face that faces the opposite side from the first end face and is in contact with a sidewall of the groove. The back plate has an end face that is in contact with the first end face. The static friction coefficient between the first end face of the snap ring and the end face of the back plate is smaller than that between the second end face of the snap ring and the sidewall of the groove.
