Since the pump chamber (32a), the valve chambers (33a and 33b), the discharge holes (33e and 33f), and the flow paths (34 and 35) are integrally provided to each other in the housing (30), in the case where these are formed of separate members, a step or the like that inhibits the flow of the cleaning liquid "W" is not formed in the flow path of the cleaning liquid "W", so that the pressure loss of the cleaning liquid "W" can be reduced. In addition, since the valve chambers (33a and 33b) of the flow paths (34 and 35) extend to the discharge holes (33e and 33f), the cleaning liquid "W" flowing out of the flow paths (34 and 35) can be discharged at a portion closer to the central of the valve chambers (33a and 33b). As a result, the outlet portions of the flow paths (34 and 35) and the inlet portions of the discharge holes (33e and 33f) is brought closer to each other, and the turbulent of the cleaning liquid "W" in the valve chambers (33a and 33b) can be suppressed, thereby reducing the pressure loss.
