Abstract

PURPOSE:To cancel a clearance between a case main body and a window, by making the formation of the window part for inside looking through metallic mold movement. CONSTITUTION:A space of an upper case main body 2' is formed with metallic molds 13, 14 and 15, a resin 17 is filled in through a gate 16 to mold the case main body 2'. After solidifying the main body 2', a metallic mold 15 is moved toward the E by the thickness's share F of a window 3' and a resin material 18 which is molten and transparent is filled in from a gate 19, allowing to bond the main body 2' and the window 3' at a boundary plane 20. Thus, the boundary between the upper case main body and the window is completely adhered, allowing to eliminate dust and dirt on the gap as conventional devices.
