Abstract
When a rotor and a case are formed from different materials, deformation and early wear due to insufficient strength of an engagement hole of a lock means which locks the relative rotation of the rotor and the case can be prevented. Furthermore it is possible to maintain a clearance between the sliding faces of the rotor and the case in response to temperature variations. A second rotating body,is formed from a material with a smaller linear expansion coefficient than a first rotating body,and an engagement hole,is provided in the second rotating body,and which engages and disengages the lock mechanism.
