To prevent impulsive sound from being produced in locking, while assuring durability of a one-way clutch.
The one-way clutch is supported in the manner that either one race of an outer race 1 and an inner race 2 is fit to a stationary member 8, and the other race is fit to a rotary member 9. Play in the fitting part of the one race to the stationary member is made smaller than that in the fitting part of the other race to the rotary member. An axial load providing means 7 is placed between the other race and the rotary member in order to control their relative rotation. Thus, while whirling of the rotary member to the other race is allowed, relative rotation caused by drag is inhibited, and impulsive sound caused in a fitting part by relative rotation in locking the one-way clutch is controlled.
