Claims

[Scope of utility model registration request]

A shaft rod equipped with a movable body made of a permanent magnet is arranged between opposing magnetic poles of an electromagnet, and the shaft rod is arranged so as to be able to reciprocate in a direction perpendicular to the direction connecting the opposing magnetic poles, and a diaphragm is attached to both ends of the shaft rod. In a diaphragm pump that vibrates the shaft rod back and forth by energizing an electromagnet, the shaft rod is fixed approximately perpendicularly to the center of a band-shaped leaf spring, and its longitudinal direction is perpendicular to the direction connecting the opposing magnetic poles. A diaphragm pump in which a plate spring is arranged so as to face in the same direction, and is held by a holder that holds both ends of the plate spring substantially fixed in the width direction but movable in the longitudinal direction.
