Abstract
To provide a hybrid drive speed change device in which a rotation sensor can be disposed appropriately from the viewpoint of reducing the axial dimension of the device. A rotary electric machine MG is disposed coaxially with an input shaft M, and includes a stator St and a rotor Ro provided radially inwardly of the stator St. An oil pumpincludes a pump casein which a pump chamberis formed, and a pump rotorrotatably housed in the pump chamber. The pump rotoris disposed coaxially with the input shaft M. A rotation sensoris disposed radially outwardly of the pump chamberand radially inwardly of the stator St of the rotary electric machine MG, and disposed to overlap the oil pumpas seen from the radial direction of the input shaft M.
