Document Type and Number:

WIPO Patent Application WO/2014/147844

Kind Code:

A1

Abstract:

The engagement device (10) is provided with: a piece (11); a sleeve (12), which is disposed on the same shaft as the piece (11) and engages with the piece (11) by moving in the axial direction; an actuator (13) for applying a thrust on the sleeve (12) in the axial direction; and a hub member (16) for connecting the sleeve (12) to a support member (32a) of a housing (32) that accepts the torque transmitted from the piece (11) during engagement of the piece (11) with the sleeve (12). The piece (11), sleeve (12) and actuator (13) are housed in a closed space. The hub member (16) serves as at least a portion of the outer wall forming the closed space that houses the engagement device (10). As a result of said configuration, even when a foreign body is generated in association with the engaging action of the engagement device (10), it is possible to keep the foreign body in the closed space and expulsion of the foreign body generated from the engagement device (10) to the outside can be prevented.
