Abstract

PURPOSE: To prevent the movable element of a reciprocatingly driving device from lowering its characteristics by interposing the movable element reciprocatingly moving by an electromagnetic action such as magnetic poles at both end surfaces of a permanent magnet and forming a magnetic element in ring shape at the outside fixedly.
CONSTITUTION: A movable element 4 is inserted into a shaft 5 of a reciprocatingly driving device. The element 4 reciprocatingly moves by the external magnetic field, and attracts magnetic poles 7 at both end surfaces of a hollow cylindrical permanent magnet 3. the element fixedly form a magnetic element 8 in ring shape at the outer periphery thereof. Thus, the magnetic path is shorted by the permanent magnet to thereby reduce the decrease of the magnetism when the element 4 is removed out of a yoke so as to eliminate the deterioration of the characteristics even when reassembling the element 4.
