<p>[PROBLEMS] To provide a cam shaft phase variable device of an engine in which the attachment angle of a crankshaft and a cam shaft is maintained surely without being shifted by disturbance torque. [MEANS FOR SOLVING PROBLEMS] The cam shaft phase variable device of an engine for automobile comprises a drive body of revolution (71) having a tubular section (71b) and a guide groove (79) of reducing diameter and rotating relatively to the cam shaft and being driven by a crankshaft, a control body of revolution (74) rotating relatively to the drive body of revolution (71) through a rotary operating force imparting means (100) and having the outer circumferential surface (74b) supported by the inner circumferential surface (71d) of the tubular section (71b), an eccentric circular cam (76) rotating synchronously with the control body of revolution (74), a movable member (81) for displacing the guide groove (79), a cam guide (77) intersecting the central axis (L1) perpendicularly and being displaced by the eccentric circular cam, and an intermediate body of revolution (84) displacing in the direction intersecting the cam guide (77) perpendicularly while being supported on the cam shaft and rotating integrally with the camshaft.</p> |
