PROBLEM TO BE SOLVED: To make it possible to easily and neatly mount a corner bumper to the corner part of a casing and to prevent the difficulty in mounting of the bumper by dimensional errors by fitting and fixing an outward engaging piece to the outer flank of the corner part of the casing and detaining an inward engaging piece thereto. SOLUTION: The upper edge of the corner bumper 30 is aligned to the position slightly lower than the upper edge of a notched part 25 of a fixture 23 and the engaging piece 31 at the left side edge of the corner bumper 30 is inserted into the spacing between the lower outward engaging piece 26 and a front plate 10 from the left side, following which the engaging piece is lifted until the piece comes into contact with the rear surface of the corner bumper 30. The engaging piece 31 on the left side of the corner bumper 30 is then detained by the outward engaging pieces 26 and 26 on the left side of the fixture 23 and the upper and lower inward engaging pieces 32 and 32 on the rear side of the corner bumper 30 have the height equal to the height of the upper and lower outward engaging pieces 26 and 26 of the fixture 23 to detain the upper and lower engaging pieces 32 and 32 on the rear side.
