Abstract

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