In the gaps 11r, 11r formed by
Mounting holes 11p, 11p and locking holes 7
The locking mechanism 11 is temporarily fixed by combining f and 7f. After the temporary fixing, the locking mechanism 11 is screwed and fixed to the front frame 4 using the screws 13 and 13. After a while, the mounting hole 11h ~
The mounting piece 11b of the locking mechanism 11 is screwed and fixed to the front frame 4 using 11h.

FIG. 7 shows a part of the completed assembly state after the above-described manufacturing process and further after the subsequent process, and FIG. 8 which is a partial sectional view taken along the line Y--Y shows an attached state. It is. In this embodiment, a gap 11 between the embossed portions 11m and 11m is provided.
Since the locking pieces 7e, 7e are housed in r, 11r, the stepped portions 4c, 4c of the above embodiment become unnecessary, and the man-hour for manufacturing the front frame 4 is reduced.

In this embodiment, the locking pieces 7e, 7e are made of a synthetic resin material. However, if they are made of a metal plate insert-molded on the mounting frame 7, it is advantageous in terms of strength. Similarly, the positioning piece 7 shown in FIGS.
The metal plates b and 7b may also be metal plate materials insert-molded in the mounting frame 7. Also, locking holes 7f, 7e of locking pieces 7e, 7e.
Instead of the portion f, a positioning pin fitted into the mounting holes 11p, 11p may be provided vertically.

In the above embodiment, the front frame is made of wood, and the mounting frame is screwed using screws.
By embedding a metal female screw member or nut body into the front frame by insert molding using the front frame as a synthetic resin material,
The mounting frame may be screwed and mounted using a male screw through a mounting hole of the locking mechanism. Similarly, a metal external thread member or bolt body is inserted into the front frame by insert molding using the front frame as a synthetic resin material and is vertically installed, and the mounting frame is inserted through the mounting hole of the locking mechanism using a nut. Then, it may be attached by screwing to a male screw member or a bolt body.

[0024]

According to the present invention, after the mounting frame is screwed and fixed to the front frame via the positioning fixing hole of the mounting frame, the positioning engaging member of the locking mechanism of the mounting frame is replaced with the locking member of the locking mechanism. Since it is decided to engage with the positioning part, the relative positions of the mounting frame, the locking mechanism, and the front frame are uniquely determined, and the positioning step using a conventional jig is not required, thereby significantly reducing the number of manufacturing steps. be able to.
