A gasket provided in a gasket groove, receives the force that acts in the direction in which two pressure-adjusting oil passages are aligned in line, and the magnitude and direction of this force change as the difference between the hydraulic pressures in the pressure-adjusting oil passages varies. However, because the opening of a hydraulic oil supply passage is located on an imaginary line extending through between the openings of the two pressure-adjusting oil passages, pressure is applied from the hydraulic oil supply passage to the gasket, whereby constant and large frictional force occurs between the gasket and the side wall of the gasket groove. Thus, the gasket is firmly retained in the gasket groove, whereby the vibration of the gasket is suppressed.
