<p>PROBLEM TO BE SOLVED: To provide a detent structure for a bushing wherein rotation of the bushing can be prevented even by small pressing force. SOLUTION: In this constitution, a flange part 15 formed in a peripheral surface of a bushing 12 is pressed to a side of a switch case 11 by a retaining cover 17, also so that the flange parts 15 of the adjacent bushings 12 are brought into contact each other. That is, the flange part 15 is interposed by the switch case 11 and the retaining cover 17, in addition, brought into contact with the flange part 15 of the adjacent other bushings 12, so as to increase resistance, given to the bushing 12 in the case of rotating relating to the switch case 11, larger than in the past. In this way, the bushing 12 is markedly prevented from easily rotating relating to the switch case 11. As a result, rotation relating to the switch case 11 can be prevented sufficiently even by tightening force of a small nut 22, in its turn, assembly workability of a switch is improved, deformation of the retaining cover 17 can be prevented.</p> |
