Abstract
A sealing member is supported by a holding surface of a vane rotor and slides on a sealing surface formed by an inner surface of a housing rotor, so as to seal an advancing chamber and a retarding chamber from each other. The sealing member has a pressure-receiving surface and a diffuser surface. The pressure-receiving surface receives pressure of working fluid from a working chamber in a direction to the sealing surface. The diffuser surface forms a sealing gap between the diffuser surface and the sealing surface, so that the sealing surface becomes larger as the sealing surface is more separated from the working chamber in a circumferential direction. The sealing member has a deformable portion forming the pressure-receiving surface and the diffuser surface. The deformable portion is elastically deformed, so that the diffuser surface is more strongly pushed to the sealing surface, when the pressure of the working fluid is increased.
