A bottom hole 4b through which a screw is inserted is formed on the side, and the bottom hole 4b has a depth corresponding to the depth of the recessed portion 3 and has an outer diameter dimension corresponding to the inner diameter of the recessed portion 3. There is.

The washer 4 is fitted into the washer part 3, and the screw 5 is inserted from the front side into the bottom hole 4b of the washer 4 and further into the screw insertion hole 2 as shown in FIG. The cabinet can be fixed to the wall surface by screwing it into the wall surface W. At this time, the head 5a of the screw 5 is attached to the washer 4
In this contact state, the head 5a of the screw 5 is in a state of being embedded in the countersunk portion 3, and the head 5a of the screw 5 does not project to the front side of the back plate 1 and is refreshing. It is possible to obtain a mounted state with excellent design.

Further, even if the screw 5 is strongly screwed in, the head 5a comes into contact with the washer 4, so that the head 5a of the screw 5 is attached to the back plate 1.
You won't be caught in it. When the screw 5 is tightened, the flange 4a of the washer 4 is in contact with the front side of the cabinet back plate 1, and the washer 4 is firmly fitted into the excavated portion 3. Since the screw 5 protrudes toward the wall surface W by the depth of the countersunk portion 3, the effective length of the screw 5 with respect to the wall surface W is longer than in the conventional case, the effect of the screw 5 is improved, and the cabinet is strengthened. It becomes possible to fix it to the wall surface W.

Next, FIG. 4 shows a mounting state of the second embodiment. In FIG. 4, a through hole 3 is formed in the back plate 1 of the cabinet in a penetrating manner. Hole 3
A washer 4 made of resin is fitted into the inside of the washer 4
Is formed in a dish shape, has a flange 4a protruding outward on the front side, and a screw insertion hole 4 through which a screw 5 is inserted on the bottom side.
b is formed, and is formed in a dish shape deeper than the washer 4 shown in FIGS. 1 and 2, and the height of the washer 4 is slightly shorter than the depth of the countersunk hole 3. Has been done.

A washer 4 is fitted into the countersunk hole 3 of the back plate 1 from the front side, and a screw 5 is inserted into the screw insertion hole 4b from the front side of the washer 4, and the screw 5 is attached to the mounting tree 6 outside the wall surface W. It can be effectively screwed in, and the head 5a of the screw 5 pushes the washer 4 into the backside of the countersunk hole 3 when screwing in, so that the collar portion 4a of the washer 4 comes into contact with the front side of the back plate 1 and the washer 4
Is tightly fitted into the countersunk hole 3, and in this state, the head 5a of the screw 5 is prevented from entering the wall surface W side, and the screw 5 can be prevented from being excessively screwed.

Since the head 5a of the screw 5 penetrates almost to the wall surface W side, the effective length of the screw 5 with respect to the mounting tree 6 and the wall surface W is extremely long, and the screw 5 can be effectively used. The cabinet can be firmly fixed to the wall surface W. Also, in the fixed state, the head 5 of the screw 5
Since a is buried in the countersunk hole 3, only the collar portion 4a of the washer 4 is exposed on the front side of the back plate 1, and a very neat mounting state can be obtained.
