    • A clutch mechanism comprises a planetary gear unit including input transmission, output transmission, and transmission stopping members. Torque entering the input transmission member is outputted downstream of the planetary gear unit by the output transmission member when the transmission stopping member is fixed and is not outputted downstream when the transmission stopping member is unfixed and entering a rotatable state. A rotation prohibiting target has an engaging target and is integral with the transmission stopping member. A rotation prohibiting member has a supporting shaft, a swingable portion at its one end and an engaging portion at its other end to engage the engaging target to enable the transmission stopping member to exert the stopping function. The engaging portion disengages the engaging target to bring the transmission stopping member into an unfixed state. A damper unit absorbs vibration caused in the rotation prohibiting member during a switching operation.
    • 离合器机构包括行星齿轮单元,其包括输入变速器,输出变速器和变速器止动构件。 当传动阻挡件固定时,进入输入传动件的扭矩由输出传动件输出到行星齿轮单元的下游,并且当传动阻挡件未固定并进入可转动状态时不会向下游输出。 旋转禁止目标具有接合目标并且与传动停止构件成一体。 旋转禁止构件具有支撑轴,其一端的可摆动部分和在其另一端的接合部分接合接合目标,以使得变速器止动构件能够发挥停止功能。 接合部分使接合目标脱开,使传动阻止件处于未固定状态。 阻尼器单元吸收在切换操作期间在旋转禁止构件中产生的振动。

    • A clutch mechanism includes a transmission element rotatable in a first direction and a second direction opposite to the first direction, integrally including a plurality of projections including a first planar surface and a second planar surface at each side of the projections in the direction of rotation of the transmission element, a rotation restriction device including a first restriction surface and a second restriction surface to contact the first planar surface and the second planar surface, to lock rotation of the transmission element, and a moving device including an actuator to move the rotation restriction device to contact and separate from the transmission element. The first restriction surface contacts the first planar surface while the transmission element rotates in the first direction, and the second restriction surface contacts the second planar surface while the transmission element rotates in the second direction.
