摘要： An excessive torque releasing type clutch apparatus which can release torque when an excessive torque is input thereto, comprises an outer ring 3, an inner ring 5 arranged radially inside and in coaxial with the center axis of the outer ring 3 and rotatably relative to the outer ring 3, a torque transmitting portion that is capable of transmitting torque having the center axis as the center between the outer ring 3 and the inner ring 5, and a restricting mechanism for restricting a torque that exceeds a predetermined torque from being input from an input torque transmitting member to a driving ring of the outer ring 3 and the inner ring 5 and an inverse torque that is input to a driven ring of the outer ring 3 and the inner ring 5 and exceeds the predetermined torque from being input to the input torque transmitting member. Treatment step for securing strength of constituent members of the clutch apparatus in manufacturing process can be simplified or omitted.

摘要： A one-way clutch apparatus of torque input-switching type in which torque capacity can be secured without increasing an axial dimension. The one-way clutch apparatus of drive input-switching type, includes a plurality of first torque transmitting members interposed between a shaft 3 and an intermediate ring 7 at circumferential predetermined intervals, and provided for transmitting torque between the shaft 3 and the intermediate ring 7, and a plurality of second torque transmitting members interposed between the intermediate ring 7 and an outer ring 5 at circumferential predetermined intervals, and provided for transmitting torque between the intermediate ring 7 and the outer ring 5, in which either the torque input into the shaft 3 or the torque input into the outer ring 5 is transmitted to the intermediate ring 7, in which the first torque transmitting member is a sprag 23 and the second torque transmitting member is a roller 29.

摘要： An object is to provide a one-way clutch that allows unlocking torque input to the movable retainer to be made low, thereby enabling downsizing of an external apparatus that inputs unlocking torque to the movable retainer. A one-way clutch 1 includes an inner ring 5, an outer ring 3, first rollers 19 used to transmit torque between the inner ring and the outer ring provided in an annular space A between the inner ring 5 and the outer ring 3, and fixed retaining portions 31 of a fixed retainer 27 and a movable retaining portions 37 of a movable retainer 33 that are arranged alternately. The one-way clutch 1 also includes second rollers 23 provided between the movable retaining portions 37 and the first rollers 19 adapted to transmit unlocking torque from the movable retaining portions 37 to the first rollers 19 and the inner ring 5 as the movable retaining portions 37 move in the clockwise direction.
