Abstract
A phase variable device for use with a car engine, capable of preventing the phase angle of the camshaft from varying relative to the first circular rotational body. The device includes: a first rotational body, an intermediate rotational bode integral with the camshaft of an engine, a second rotational body, all rotatably arranged on the same camshaft, the device adapted to control phase angle of the second rotational body, thereby varying the phase angle of the intermediate rotational body. The second rotational body is placed in substantial contact with the inside of the hollow cylindrical section of the intermediate rotational body. A circular eccentric cam, integral with the second rotational body and adapted to rotate about an eccentric center thereof, causes a cam guide plate to reciprocate in the direction perpendicular to the rotational axis.
