When an engine speed of an engine is low, a force by a spring to bias a low speed lock pin in the direction in which the pin is to be inserted into a low speed pin introduction hole is greater than a centrifugal force acting on a weight. This causes the low speed lock pin to be inserted into the low speed pin introduction hole, so that the phase of an intake camshaft relative to an exhaust camshaft is fixed. When the engine speed of the engine is high, a force to bias a high speed lock pin in the direction in which the pin is to be inserted in a high speed pin introduction hole by a centrifugal force acting on a weight is greater than a force by a spring to bias the high speed lock pin in the direction in which the pin is pulled out from the high speed lock pin introduction hole. This causes the high speed lock pin to be inserted into the high speed pin introduction hole, so that the phase of the intake camshaft relative to the exhaust camshaft is fixed.
