PROBLEM TO BE SOLVED: To miniaturize a solenoid pump while reducing magnetic loss.SOLUTION: A solenoid pump 40 is applied to a brake hydraulic pressure control device of a bar handle vehicle such as a motor cycle. In the solenoid pump 40, a pump housing 41 is composed of a first member 46 including a through hole 45 to which a piston 51 is inserted, and used as a fixed core, and a second member 47 provided with a suction valve 70 and a discharge valve 80. An inner peripheral portion of the first member 46 is provided with a return spring 64, and a seal member 56 for sealing between the second member 47 and the piston 51 is disposed on a position out of an inner diameter direction of a coil 44 in a space 45d formed between the first member 46 and the second member 47.EFFECT: A part between the pump housing and the piston can be sealed, and the solenoid pump can be miniaturized while reducing magnetic loss.SELECTED DRAWING: Figure 2 |
