ABSTRACT:
A reduction mechanism for a tape recorder is disclosed, and the mechanism includes a lower gear box, an upper gear box and a main chassis. The lower gear box contains a plurality of reduction gears, and the upper gear box covers the lower gear box, with the upper gear box being secured to the lower gear box in an integral form by being microwave-welded. The lower and upper gear boxes constitute a reduction mechanism, and the reduction mechanism is secured to the main chassis by means of screw members. According to the present invention, the displacements of the components are prevented so as for the reducing function to become wholesome, and the productivity is improved.
