The present invention improves the openability of a suction valve and achieves miniaturization. A suction valve (6) is opened by a pressure difference between a brake hydraulic pressure on a master cylinder (M) side and a brake hydraulic pressure on a suction inlet side which becomes negative pressure through actions of pumps (5a, 5b). The suction valve (6) is provided with a normally-closed one-way valve (61), a plunger (62) that abuts against a valve body of the one-way valve (61) to be opened, and a diaphragm (64) that pushes the plunger (62) when the suction inlet side becomes negative pressure through the actions of the pumps (5a, 5b), and biases the one-way valve (61) in an opening direction. The one-way valve (61) is housed in a housing part provided to a base body (100). The effective diameter of the diaphragm (64) is larger than the inner diameter of the housing part.
