Claims

[Scope of Claim for Utility Model Registration] (1) An electromagnet section that generates magnetic flux in an air gap section by a current flowing through a coil, a mover disposed in the air gap section of the electromagnet section and incorporating a permanent magnet, and a mover that vibrates back and forth. The pump has a diaphragm supported at both ends by a center plate provided approximately in the center, and sucks in and discharges fluid by reciprocating vibration of a mover driven by an electromagnet when power is turned on. A pump characterized in that at least two or more pairs of protrusions are formed close to the outer peripheral edge of the plate, and a protrusion that fits between the pair of protrusions is formed at the end of the mover. Mover stop structure. (2) A stopping structure for a pump mover according to claim 1 of the utility model registration claim, characterized in that an arm piece that fits between the convex portions is formed to protrude from an end of the mover. .
