In a hybrid drive device including a rotating electric machine, a transmission, and a case, a rotor support member that supports a rotor of the rotating electric machine includes an annular member that faces an end wall portion of the case; the end wall portion includes a first tubular portion axially protruding from the inner circumference toward the transmission, and a second tubular portion axially protruding toward the transmission so as to enclose the first tubular portion; the annular member includes a tubular portion axially protruding from the inner circumference toward an engine; an inner radial bearing is disposed between a first transmission shaft and the inner peripheral surface of the first tubular portion of the end wall portion; a gap is formed between the outer peripheral surface of the first tubular portion of the end wall portion and the inner peripheral surface of the tubular portion of the annular member; and an outer radial bearing is disposed between the outer peripheral surface of the tubular portion of the annular member and the inner periphery of the second tubular portion of the end wall portion. As a result, the durability of the bearing for supporting the rotor of the rotary electric machine in the radial direction can be further improved.

    在包含旋转电机、变速机以及罩的混合驱动装置中,支承旋转电机的转子的转子支承部件包含与罩的端壁部对置的环状部件,端壁部包含从内周朝向变速机在轴向上突出的第一筒状部、和以包围第一筒状部的方式朝向变速机在轴向上突出的第二筒状部,环状部件包含从内周朝向发动机在轴向上突出的筒状部,在第一传动轴与端壁部的第一筒状部的内周面之间配置内侧径向轴承,在端壁部的第一筒状部的外周面与环状部件的筒状部的内周面之间形成间隙,在环状部件的筒状部的外周面与端壁部的第二筒状部的内周面之间配置外侧径向轴承。由此,能够进一步提高用于在径向上支承旋转电机的转子的轴承的耐久性。
