    • PURPOSE: To provide a one-way clutch unit capable of reducing the number of part items, shortening axial size, reducing cost, and realizing compactness. CONSTITUTION: 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.
    • 目的:提供能够减少零件数量,缩短轴向尺寸,降低成本,实现紧凑性的单向离合器单元。 构成:在该单向离合器单元中,用于单向离合器1的第一外圈部6与用于深沟槽轴承2的第二外圈部7一体地形成为一体的外圈3,并且第一内圈 用于单向离合器的环形部分8与用于深沟槽轴承的第二内圈部分10集成为一体的内环5.可以减少零件的数量,并且可以缩短轴向尺寸,使得 可以实现成本降低和紧凑性。 在第一内圈部8的十字形外周凸轮面8A与第二内圈部10的外周面之间存在的锥形面18与一体的外圈3的内周面之间形成有圆形的部分17A 设置有冠状保持件17。 因此,可以限制由冠形保持件17引起的轴向尺寸的增加,从而可以缩短轴向尺寸。

    • PURPOSE: To prevent intrusion of foreign matter such as muddy water, even under a strict environment such as high speed car washing, in a pulley unit A equipped on auxiliary machines of an automobile. CONSTITUTION: This pulley unit is constituted of a pulley 1, a shaft body 2 disposed relatively rotatably with the pulley 1 and concentrically on the inside of the pulley 1, a one-way clutch 3 interposed into an annular space S between the pulley 1 and the shaft body 2, rolling bearings 4 and 5 adjacently provided in a shaft direction of the one-way clutch 3 in the annular space S, inside annular seals 61 and 62 provided on the outside of the rolling bearings 4 and 5 to seal the annular space S, and an outside annular seal 8 provided on the outside of the inside annular seals 61 and 62 to seal the annular space S. In the outside annular seal 8, a lip 8b in provided at a tip, a base end part 8a is fixed to either one of an inner peripheral surface of the pulley 1 or an outer peripheral surface of the shaft body 2, and the lip 8b is brought into contact with the other.
    • 目的:即使在高速洗车等严格环境下,也可以在配备有汽车辅机的滑轮单元A中,防止异物如泥水等的侵入。 构成:该滑轮单元由滑轮1,与滑轮1相对旋转地配置并同心地配置在滑轮1的内侧的轴体2构成,该单向离合器3插入在滑轮1与滑轮1之间的环状空间S中 轴体2,在环状空间S中沿单向离合器3的轴向相邻设置的滚动轴承4和5,设置在滚动轴承4和5的外侧的环形密封件61和62内部,以密封环形 空间S和设置在内部环形密封件61和62的外侧上以密封环形空间S的外部环形密封件8.在外部环形密封件8中,设置在尖端处的唇部8b,基部端部8a是 固定在滑轮1的内周面或轴体2的外周面中的任一个上,并且唇部8b与另一个接触。
