The first and second parts 12 and 13 of the plastic chassis 11, which together with the part 13 form an L shape, are provided with relatively large holes 14 and 15, respectively. Furthermore, first and second portions 1 are provided near the holes 14 and 15.
A pair of ribs 16 and 17 are provided perpendicular to both of the ribs 2 and 13, and engagement protrusions 18 and 19 and locking recesses 20 and 21 are formed in the ribs 16 and 17. On the other hand, the holes 1 in the first and second parts 12 and 13
4, 15, said first and second parts 12, 1
A metal fitting 22 is prepared which includes flat portions 23 and 24 that are substantially flush with the metal fitting 3, and an L-shaped portion 25 that connects the flat portions 23 and 24. It is assumed that the flat parts 23 and 24 of the metal fitting 22 are provided with screw holes 26 and 27. Further, the L-shaped portion 25 has small holes 28 and 29 that fit into the engagement protrusions 18 and 19, and engagement portions 30 and 31 that engage with the locking recesses 20 and 21.
will be established. A recess 32 recessed by the thickness of the flat portion 23 of the metal fitting 22 is provided above the hole 14 formed in the first portion 12 . When attaching the metal fitting 22 to the plastic chassis 11, insert it as shown by the dashed line 33 in FIG. 2, and then rotate it in the direction A to fix it in place. In this state, the metal cabinet 34 is applied from the direction of arrow B and fixed to the flat portion 23 with screws 36. Similarly, the bottom mold 36 is fixed to the other flat part 24 from the bottom side with screws 37.
