PURPOSE:To hold exactly a metallic block by a connecting part by packing a part of a plastic material for forming the connecting part into upper and lower through-holes of an aperture for prescribing an image size, provided on the metallic block for reinforcing a camera body. CONSTITUTION:When a metallic block 2 is fitted to a rear mold 6 from the front, and subsequently, a front mold 7 is fitted, an injecting gate 8a of a spool 8 fitted to the front mold 7 is fitted into a through-hole 2a. When a thermoplastic material containing a glass fiber is made to flow into the spool 8, and injected into a space corresponding to connecting parts 1a, 1b of a containing body 1 through the injecting gate 8a and the through-hole 2a, it is packed to spaces 9, 10 corresponding to box-like parts 1c, 1d of the body 1. After said material is solidified, it is taken out and a burr is removed. The plastic material is packed in the through-hole 2a, too, therefore, the metallic block 2 is held exactly. |
