Abstract

Provided is a two-way clutch of which the size in the axial direction can be made compact. A first engaging piece (5) and a second engaging piece (6) are disposed in a first wedge-shaped space (S1) and a second wedge-shaped space (S2) between an outer member (2) and an inner member (3). The first engaging piece (5) is held by a first holder (7), and the first holder (7) is enabled to oscillate within the outer member (2). The second engaging piece (6) is held in a second holder (8), and the second holder (8) is enabled to oscillate within the outer member (2). In a side surface view orthogonal to the axial direction of the first engaging piece (5) and the second engaging piece (6), at least part of the first engaging piece (5) and at least part of the second engaging piece (6) overlap in the axial direction. The first holder (7) is configured so as to allow the second engaging piece (6) to oscillate along with the second holder (8). The second holder (8) is configured so as to allow the first engaging piece (5) to oscillate along with the first holder (7).

Description

technical field [0001] The present invention relates to a two-way clutch for locking and unlocking two-way (clockwise and counterclockwise) rotation. Background technique [0002] As such a two-way clutch, that described in JP-A-2008-057566 is known. This conventional two-way clutch includes an outer member, an inner member arranged inside the outer member, and first and second engaging members arranged between the outer member and the inner member. A plurality of cam surfaces forming a plurality of wedge-shaped cavities between the inner member and the inner member are formed on the inner face of the outer member. The first engaging parts and the second engaging parts are arranged in the plurality of wedge-shaped cavities. The first engaging piece is held by the first holder. The first retainer swings relative to the outer member, so that the first engaging member engages and disengages with the cam surface. The second engaging piece is held by the second holder. The s...
