摘要：
An oil drain structure of a valve timing adjusting device for an internal combustion engine is provided to adjust a valve timing of at least one of an intake valve and an exhaust valve by a torque of a cam shaft and a pressure of a working fluid. The oil drain structure of the valve timing adjusting device includes a rotation preventing means to suppress a position change between a rotor and a housing by regulating a relative rotation of the rotor with respect to the housing.
