PROBLEM TO BE SOLVED: To resolve a problem found in the prior art that an L-shaped wall fixing bracket can be engaged in thread only with a long hole slit of a cover opened in its horizontal direction and a mounting distance between a casing and a wall surface is limited by a width of the long hole slit.SOLUTION: An arm part 5 is set in such a way that a substantial diagonal line and a length of the substantial same length as that of diagonal line are combined to enable a wall fixing bracket 4 and the arm part 5 to be turned around a rotation center of a fixture 7, a rear surface cover 2 and the arm part 5 can be turned around the rotation center of an adjustable fixture 6 and at the same time when a setting distance is a far distance, the wall fixing bracket 4 and the arm part 5 are set in horizontal orientation to fix a casing 1 against a wall 3 and in turn when the setting distance is near, the arm part 5 and the wall fixing bracket 4 are angled to enable them to be fixed, so that it is possible to expand a range that can be mounted by a simple configuration without replacing a long bracket and a short bracket to each other depending on the setting distance.SELECTED DRAWING: Figure 2 |
