A piston is configured by a piston body and a support such that the piston is divided, along a direction of axis line, into the piston body, which is formed integrally with a valve element, and the support, which is provided separately from the valve element. A piston ring, which slides along a body, is held between the piston body and the support. The piston body is constantly in contact with one side face of the piston ring, and the support is constantly in contact with the other side face of the piston ring.
