<p>A discharge valve (80) is provided in a discharge section (70) integrally formed with a housing main body (11). A spring seat member (81) of the discharge valve is accommodated inside a discharge passage (23) defined by the discharge section. Movement of the spring seat member accommodated in the housing main body is restricted by a ring (85), and the spring seat member is held by the housing main body. Thus, binding between the housing main body and the discharge section is unnecessary, and a sealing member to be provided between the housing main body and the discharge section for preventing fuel leak is unnecessary. The spring seat member is formed in a cylindrical shape with a first passage (91) and a second passage (92). Thus, a passage, through which the fuel pressurized in the pressurization chamber flows, is ensured.</p> |
