    摘要： A reverse-input blocking clutch, comprising a pressed member, an input member, an output member, and an engaging element, the pressed member including a first pressed member element having a pressed surface around an inner peripheral surface thereof and a second pressed member element having a mounting portion fixed to a portion that does not rotate during use, the engaging element configured to transmit rotational torque input to the input member to the output member by moving in a direction away from the pressed surface and to completely block rotational torque reversely input to the output member or transmit a part of the rotational torque reversely input to the output member to the input member and block a remaining part thereof.

    摘要： A torque transmission mechanism transmits a torque produced by a rotation of a driving shaft to an output shaft. A clutch mechanism is provided between a motor and the torque transmission mechanism. The torque transmission mechanism includes a magnet coupling including a driving magnet member coupled to the driving shaft side and a driven magnet member coupled to the output shaft side. The driving magnet member and the driven magnet member are arranged such that magnetic surfaces on each of which S-pole magnets and N-pole magnets are alternately arranged face other. The clutch mechanism transmits the torque produced by the rotation of the driving shaft to the driving magnet member but does not transmit a torque the driving magnet member receives from the driven magnet member to the driving shaft.

    摘要： A clutch unit includes a lever-side clutch part to control transmission of rotational torque input through a lever operation, and a brake-side clutch part to transmit the rotational torque from the lever-side clutch part to an output side, and interrupt rotational torque from the output side. The brake-side clutch part includes an outer ring constrained in rotation, an output shaft configured to output the rotation, a cage arranged between the outer ring and the output shaft to receive the rotational torque from the lever-side clutch part, and a cylindrical roller to control the interruption of the rotational torque from the output shaft and the transmission of the rotational torque input from the cage through engagement and disengagement between the outer ring and the output shaft.

    摘要： A clutch is configured, when a driving-side rotor is in a non-driven-rotated state, to prevent rotation of a driven-side rotor by setting a rolling element in a lock state in which the rolling element is held by a control surface and a collar. The clutch is configured so that when the driving-side rotor is driven and rotated in the lock state, the driving-side rotor pushes the rolling element via two circumferential holders in a rotation direction to release the rolling element from the lock state. Each of the two circumferential holders includes a guide portion configured to guide the rolling element toward a radially inner side of the collar when the rolling element is released from the lock state.

    摘要： A transaxle includes a transaxle casing, a bi-directional overrunning clutch in the transaxle casing, a friction mechanism, and a clutch-off biasing mechanism. The bi-directional overrunning clutch includes coaxial input and output members journalled by the transaxle casing, and includes a cage disposed between the input member and the output member. Rollers carried by the cage are rotatable to follow rotation of the output member. The cage is rotatable relative to the input member according to the rotation of the rollers following the output member until the rollers contact the input member to engage the bi-directional overrunning clutch. The friction mechanism applies a friction resistance to the cage to rotate the cage relative to the input member. The clutch-off biasing mechanism biases the cage to the initial position. The friction mechanism and the clutch-off biasing mechanism are distributed in the transaxle casing at first and second end portions of the cage.
