PROBLEM TO BE SOLVED: To restrain the looseness of a push-button member of a push-button switch. SOLUTION: A rib 22 extended in a pressing direction is fitted to a retainer of the push-button member pressing the switch, and a guide groove 24 is fitted to a housing member 12 for the rib 22 to be inserted into the groove in free sliding movement. The rib 22 is structured of free-fitting rib parts 22a, 22b sliding into the guide groove 24, and an insertion-coupling rib part 22c formed in a tapered shape so as to couple their side faces, and the guide groove 24 is formed in correspondence with the shape of the rib 22. At resetting of the switch, the insertion-coupling rib part 22c of the rib 22 is pressed to and insertion-coupled with an insertion-coupling guide groove 24c of the guide groove 24 by biasing force of the switch. With this, the looseness of the push-button member can be restrained at the resetting of the switch. COPYRIGHT: (C)2005,JPO&NCIPI
