When the middle frame 9 is mounted on the plate frame 1, the locking claws 10 of the middle frame 9 are fixed to the locking recesses 11 of the plate frame 1 so as to be mounted. The positions of the locking claws 10 to the locking recesses 11 are shifted so that the center of the middle frame 9 is slightly shifted from the center toward the rotation fulcrum of the handle 22. By attaching the middle frame 9 in this manner, the handle 22 is attached such that the center of the handle 22 is shifted from the center of the decorative frame 28. That is, as shown in FIG. 1, the center line b of the handle 22 is displaced from the center line a of the decorative frame 28, and the gap S between the decorative frame 28 and the handle 22 is located on the rotation fulcrum side of the handle 22. It is narrow and wide on the operation mark 23 side of the handle 22. The width A of the gap S on the rotation fulcrum side of the handle 22 is narrow, and the width B of the gap on the operation mark 23 side is wide.
As a result, when operating the handle 22 by pressing the operation mark 23 of the handle 22, the handle 22 is
The handle 22 can be smoothly operated without being caught on the handle 8.

As shown in FIG. 5, the refractory panel 16 is formed by bending claws 21 at four locations on the outer peripheral portion of the refractory panel.
The outer surface of the claw 21 is formed by cutting and raising the claw portion 54. Accordingly, when the refractory panel 16 is mounted on the front surface of the plate frame 1 and the claws 21 are inserted into the holes 20, the claws 54 are locked on the inner side surfaces of the holes 20, so that the refractory panels 16 are securely attached to the plate frame 1. Can be fixed.

On the outer peripheral portion of the fireproof panel 16, square holes 51 are formed at four places for escape for inserting the locking claws 29 of the decorative frame 28. Therefore, the decorative frame 28 can be attached to the plate frame 1 without the fire panel 16 being in the way.
Can be fixed. Further, a square hole 17 is formed in the center of the refractory panel 16 as described above, so that the front surface of the switch 14 is exposed from the hole 17 to facilitate operation. Further, the shape of the hole 17 can be processed according to the shape of the instrument used.

Further, the size of the hole 18 through which the screw 5 is inserted is larger than the head of the screw 5, so that there is a possibility that the fireproof panel 16 alone may fall off. Therefore, a convex portion 52 is provided so as to project inward from both sides of the inner edge of the hole 18. Convex part 52
Since the distance between them is smaller than the head of the screw 5, the head of the screw 5 is hooked on the projection 52, so that the fireproof panel 16 alone can be prevented from falling off.

On the other hand, when the plate frame 1 is directly attached to the construction surface, the holes 19 of the fireproof panel 16 through which screws are inserted also have the same convex portions 53 as those described above. Also in this case, the single fireproof panel 16 can be prevented from falling off.

[0024]

According to the present invention, as described above, the gap formed between the outer periphery of the handle and the decorative frame is such that the side serving as the pivot point of the handle is narrowed and the side on which the handle is pressed is widened. Because the inner frame is displaced, the piano handle touches even if the gap between the decorative frame and the handle does not deteriorate the appearance.
Thus, the handle can be prevented from being caught on the decorative frame when the handle is pushed, and there is no danger of operating failure when operating the handle.
