PROBLEM TO BE SOLVED: To prevent generation of looseness by constituting the subject structure of a main body having a plurality of push buttons. a positioning part integrally molded with the main body and has a round hole with a cut portion at its end, a cylindrical positioning pin, and a slip-off prevention part arranged at a tip of the pin so as to prevent slipping of the positioning part. SOLUTION: In fixing a main body 1 provided with a plurality of push buttons 2, a cylindrical positioning pin 4 at a lower part of a slip-off prevention part 5 is fitted to a cut portion at a tip of a positioning part 3 integrally molded with the main body 1. The pin 4 can be inserted into the cut portion of the part 3 without looseness by the aid of spring characteristic of the cut portion. Accordingly, positioning of push buttons can be made surely in terms of outer looking, and additional man-hours for molding adjustment, fusing operation and screwing operation can be reduced. This structure can be applicable to the structure of connection for two or more parts.
