摘要：
A valve timing control apparatus for an internal combustion engine has a lock pin that is movably provided in an accommodation hole of one of vanes of a rotor. A screw portion is formed along part of the outer circumference of the lock pin, which is fixed to a shaft of a motor. When hydraulic pressure control is performed to maintain a housing and the rotor in a predetermined intermediate phase, the lock pin moves in the axial direction of a cam shaft in response to rotation of the motor independently of the hydraulic pressure control, and engages a lock recess portion formed in a sprocket.
