An end portion on a side of a deep groove ball bearing portionof a second one-way clutchis disposed in an annular recess, which is provided at an end portion in an inner peripheral surface of a first inner ring, so that the dimension in an axial direction of a one-way clutch unit is reduced. Further, an outer peripheral diameter on a side of the deep groove ball bearing portionis made smaller than that on the side of a one-way clutch portionof a second outer ringso as to reduce a diameter of the recessand the outer peripheral diameter of the first outer ringof the first one-way clutch
