Abstract

A drive force transmission device is provided with a motor shaft, a transmission input shaft, a drive side sprocket, a resolver rotor and a cylindrical resolver retainer. The motor shaft is configured to be connected to a motor rotor of a motor. The driving force transmission shaft is coaxially connected to the motor shaft. The oil pump sprocket is provided on the driving force transmission shaft for rotating an oil pump. The resolver rotor is disposed on the motor shaft adjacent the oil pump sprocket for detecting a rotational position of the motor. The cylindrical resolver retainer is coaxially disposed on the motor shaft to fix the resolver rotor to the motor shaft. The resolver retainer includes a stopper that forms an axial positioning surface for the resolver rotor by contacting an end portion of the motor shaft, and an axial position limiting surface of the oil pump sprocket.
