摘要： A power transmission device includes a first one-way clutch (1) that transmits a rotational power of a pulley (3) to a rotating shaft (6), and a second one-way clutch (2) that transmits a rotational power of a rotor (11) of a motor (10) to the rotating shaft (6). The first one-way clutch (1) is of inner cam type in which an engagement cam-surface is formed in an outer periphery of a first inner ring (7), while the second one-way clutch (2) is of outer cam type in which an engagement cam-surface is formed in an inner periphery of a second outer ring (14). This arrangement improves engagement performance of the first one-way clutch (1) as well as reducing heat generation of the second one-way clutch (2), so that the lifetime of grease is prolonged.

摘要： There is provided a one-way clutch unit that is simple in structure and compact. An annular recess 67 is provided in an inner periphery of a side of a deep groove ball bearing portion 55 of a first inner ring 7 of a first one-way clutch 1, and an end portion on the side of a deep groove ball bearing portion 65 of a second one-way clutch 2 is disposed in the annular recess 67. Thereby, the dimension in an axial direction of the one-way clutch unit is reduced by a dimension in the axial direction of the second one-way clutch 2 that is disposed in the annular recess 67. The thicknesses on the sides of the deep groove ball bearing portions 55, 65 of the first inner ring 7 and the second outer ring 14 are set larger than those on the sides of the one-way clutch portions 50, 60, whereby deterioration of strength of the one-way clutch unit against radial loads, which is attributable to provision of the annular recess 67 in the inner periphery of the side of the deep groove ball bearing portion 55 of the first inner ring 7, is prevented.

摘要： There is provided a compact one-way clutch unit that can perform connection and disconnection of power in two systems. An end portion on a side of a deep groove ball bearing portion 65 of a second one-way clutch 2 is disposed in an annular recess 67, which is provided at an end portion in an inner peripheral surface of a first inner ring 7, 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 portion 65 is made smaller than that on the side of a one-way clutch portion 60 of a second outer ring 14 so as to reduce a diameter of the recess 67 and the outer peripheral diameter of the first outer ring 5 of the first one-way clutch 1.
