The housing side convex portion 172 is provided in the direction of the lower side when attached to the display device 1, and the base plate side convex portion 22 is provided on the upper side of the engaging shape 21, and the lower portion of the display device 1 and the lower portion of the base plate 20 are provided. The display device 1 is hooked on the base plate 20 by the housing-side convex portion 172 and the base plate-side convex portion 22 when they are engaged with each other.

Next, with reference to FIG. 14, the length of the base plate side convex portion 22 in the longitudinal direction will be described. FIG. 14 is a diagram for explaining the length of the base plate side convex portion 22 in the longitudinal direction. As shown in FIG. 14, the width (length in the X direction) D of the recess 170 is slightly longer (D> d) than the width (length in the X direction) d of the engaging shape 21. Therefore, when the display device 1 is attached to the base plate 20, even if the display device 1 is temporarily placed on the base plate 20, the display device 1 moves in the X direction by the length of Dd (so-called). "Play"). The length of the base plate side convex portion 22 of the present embodiment in the longitudinal direction is substantially the same as that of this "play", that is, Dd, or slightly longer than Dd. As a result, even if the display device 1 is displaced in the X direction by the amount of "play", the display device 1 is surely not caught by the housing side convex portion 172 and the base plate side convex portion 22. It is possible to prevent slipping in the direction away from the base plate 20.
