HYBRID DRIVE DEVICE

摘要

The purpose of the present invention is to suppress elongation in the axial direction of a hybrid drive device, in cases such as when a vehicle is driven by drive force from an internal combustion engine without the use of drive force from a rotating electrical machine, and even if provided is a mechanism that enables the rotating electrical machine to not rotate with the internal combustion engine. A second engagement device (C2) connects or separates a rotor support member (3) and a second input member (2). A first engagement device (C1) and the second engagement device (C2) are disposed further radially inward than a support cylindrical part (31) of the rotor support member (3). The second input member (2) comprises a cylindrical input cylindrical part (22) that is disposed on the radially outward side of a case boss section (52) and the input cylindrical section (22) supports a first oil chamber forming member of the first engagement device (C1) and a second oil chamber forming member of the second engagement device (C2).
