Claims

[Scope of utility model registration request]

A fixed iron core into which the main shaft is inserted so that it can move freely, and a fixed core that is fixed to the above main shaft! An electromagnetically driven reciprocating pump comprising a movable core that is attracted to the fixed core, and a hard elastic material that is fitted onto the outer periphery of the main shaft and is in contact with the movable core; An electromagnetically driven reciprocating pump characterized in that a cushion made of a soft elastic material that receives and stops an end surface on the opposite side of the movable core is fitted into a recess provided at the end of the fixed core on the movable core side.
