ABSTRACT:
A reciprocating motor in which a plurality of eddy current preventing holes (26) are formed in the directions of circumference and shaft of a magnet frame (10) in a magnet mounting portion (12) of the magnet frame (10)connected between the magnet (8)and component part which will perform a reciprocating movement, for transmitting a reciprocating movement of the magnet (8) to a component part, to prevent deformation of the magnet frame (10)in molding the eddy current (26) and maintain roundness of the magnet frame precisely by improving the structure of the eddy current preventing holes which are molded in the magnet frame.
