PURPOSE: To prevent movement in a housing of operation members of a display device and easily recognize switch operation display by using at least one part of a locking piece of the display device as a positioning member so that the display device does not move in the specified direction. CONSTITUTION: First locking pieces 6, 6 and second locking pieces 7, 7 are formed on both end surfaces 5a, 5b in the parallel direction to a major axis, an elliptic convex-shaped lense part 8 is formed in almost the central part of an upper surface 5c, and a lower surface 5d is recessed in almost the same shape as the lense part 8. The pieces 6, 6 and the pieces 7, 7 are engaged with engaging holes 14, 14, 15, 15 of a housing 13, and especially the pieces 6, 6 act as a positioning member for positioning a display device 5 so as not to move in the direction connecting the end surfaces 5a, 5b within the housing 13. Since the display device 5 does not move within the housing 13 in the direction connecting both end surfaces of the device by the pieces 6, 6 serving as the positioning member, display of switching operation is easy to see, appearance is enhanced, coming off from the housing 13 is suppressed, and reliability is enhanced. |
