PROBLEM TO BE SOLVED: To improve operability of securing a switch device by screws, and to makes the switch device hard to become deformed even if a switch attachment cover is pushed from the outside. SOLUTION: Projections 22 are formed on both the right and left sides of a switch device 7 to project from the sides respectively, and projection inserting apertures 9 are formed on both the right and left sides of the upper portion of an insertion aperture in a lower cover 4. The back of the switch device 7 is inserted into the insertion aperture from the front, both projections 22 on the right and left are inserted into the projection inserting apertures 9 respectively, and the switch device 7 is sifted downward. Corresponding to this, respective projections 22 are located on the reverse of the lower cover 4, the periphery of the insertion aperture in the lower cover 4 is sandwiched between respective projection 22 and an overhanging section 17 of the front of the switch device 7, and the switch device 7 is temporarily fixed.
