PURPOSE:To accurately assemble an outer plate by providing a connecting hole and a connecting protrusion to be engaged with the hole at opposite positions of the plate and a body. CONSTITUTION:An engaging protrusion 3 of an outer plate 1 is formed and a connecting hole 4 is opened at an opposite position at a frame of a body 2 side. The relationship between the protrusion 3 and the hole 4 can be variously considered. As one example, the protrusion 3 is formed in an arrow tail state formed at its end with a hook piece 3a, which is engaged with a rear side edge of a body side connecting hole not to be disengaged when the protrusion 3 is strongly pressed into the hole by utilizing elasticity, etc., of the protrusion 3 when the piece 3a is inserted to the slit-shaped hole 4 smaller in width than the piece 3a, thereby mounting the plate 1. Thus, the plate can be accurately, precisely mounted at its mounting position. |
