摘要： PROBLEM TO BE SOLVED: To provide a compact one-way clutch unit for performing on-off operation of the power of two systems and a one-way clutch to be used for the one-way clutch unit. SOLUTION: The end of a second one-way clutch 2 at on the side of a deep groove ball bearing portion 65 is placed in an annular recessed portion 67 provided on the inner peripheral face at the end of an first inner ring 7. Thereby, the axial size of the one-way clutch unit is shortened. The outer diameter of the outer peripheral face of a second outer ring 14 at the side of the deep groove ball bearing portion 65 is made smaller than the outer diameter of the outer peripheral face of the second outer ring 14 at the side of a one-way clutch portion 60. Thereby, the diameter of the recessed portion 67 and the outer diameter of the outer peripheral face of a first outer ring 5 of a first one-way clutch 1 are made smaller.

摘要： PROBLEM TO BE SOLVED: To provide a power transmission device with first and second one-way clutches, having simple and compact construction. SOLUTION: The power transmission device comprises the first one-way clutch 1 for transmitting the rotating power of a pulley 3 to a rotating shaft 6 and the second one-way clutch 2 for transmitting the rotating power of a rotor 11 of a motor 10 to the rotating shaft 6. The first one-way clutch 1 is of an internal cam type and a first inner ring 7 has an engagement cam face formed on the outer periphery, while the second one-way clutch 2 is of an external cam type and an second outer ring 14 has an engagement face formed on the inner periphery. Thus, the meshing performance of the first one-way clutch 1 is improved and the heating of the second one-way clutch 2 is suppressed, which provides a longer service life of grease.

摘要： PROBLEM TO BE SOLVED: To provide a one-way clutch unit capable of reducing the number of part items, shortening axial size, reducing cost, and realizing compactness.
SOLUTION: In this one-way clutch unit, a first outer ring part 6 for a one- way clutch 1 is integrated with a second outer ring part 7 for a deep groove bearing 2 to be an integrated outer ring 3, and a first inner ring part 8 for the one-way clutch is integrated with a second inner ring part 10 for the deep groove bearing to be an integrated inner ring 5. The number of part items can be reduced, and the axial size can be shortened, so that cost reduction and compactness can be achieved. Between a taper surface 18 existing between a decagonal outer circumferential cam surface 8A of the first inner ring part 8 and an outer circumferential surface of the second inner ring part 10, and an inner circumferential surface of the integrated outer ring 3, a circular part 17A of a crown-shaped holder 17 is disposed. The increase of the axial size caused by the crown-shaped holder 17 can thus be restricted, thereby the axial size can be shortened.

摘要： PROBLEM TO BE SOLVED: To provide a pulley unit with a cover member hard to come-off even when gas inside the cover member thermally expands.
SOLUTION: A bearing 100 is fixed to the inside of a pulley 1 and the cover member 15 is fixed to the inner periphery of the pulley 1. The cover member 15 consists of a core metal portion 16 and an elastic portion 17 covering an opening portion 16f of the core metal portion 16. The elastic portion 17 has a slit 17c in a portion covering the opening portion 16f of the core metal portion 16. Even when gas inside the cover member 15 thermally expands to increase the pressure inside the cover member 15, the slit 17c is elastically deformed in the expanding direction to cause the flow of the gas inside the cover member 15 to the outside to relax a difference in pressure between the inside and the outside of the cover member 15.

摘要： PROBLEM TO BE SOLVED: To provide a one-way clutch unit having simple and compact construction. SOLUTION: An annular recessed portion 67 is provided on the inner periphery of a first inner ring 7 of a first one-way clutch 1 at the side of a deep groove ball bearing portion 55, and the end of a second one-way clutch 2 at the side of a deep groove ball bearing portion 65 is placed in the annular recessed portion 67. Thus, the axial size of the one-way clutch unit is shortened by the axial size of the one-way clutch 2 arranged in the annular recessed portion 67. The thicknesses of the first inner ring 7 and a second outer ring 14 at the sides of the deep groove ball bearing portions 55, 65 are greater than those at the sides of one-way clutch portions 50, 60, preventing the degradation of the radial load strength of the one-way clutch unit due to the annular recessed portion 67 provided on the inner periphery of the first inner ring 7 at the side of the deep groove ball bearing portion 55.

摘要： PROBLEM TO BE SOLVED: To provide a compact power transmission simplified in structure and a one-way clutch unit usable for the power transmission. SOLUTION: The small diameter cylindrical part 62 of a power transmission shaft 6 is loosely fitted to the cylindrical surface 29 of the second inner ring 15 of a second one-way clutch 2 and the thread part 20 of the first inner ring 7 of the first one-way clutch 1 is threaded to the screw part 63 of the power transmission shaft 6. The screw part 20 of the first inner ring 7 of a first one-way clutch 1 is strongly fastened to the second one-way clutch 2 to strongly press, from both sides, the second inner ring 15 by the end face 71 of the first inner ring 7 and the step part 72 of the power transmission shaft 6. Accordingly, a frictional force is generated between the end face 71 and the step part 72. Thus, the rotational power of the motor 10 transmitted to the second inner ring 15 can be transmitted to the power transmission shaft 6 through the end face 71 and the step part 72.
