Abstract

A positioning structure having a positioning projection on attaching surface is provided. The attaching surface is inclined within an acute angle with respect to a direction orthogonal to an opening and closing direction of a mold for forming the surface. The positioning projection formed on the attaching surface is molded simultaneously by the metallic molding into a truncated right circular conical shape with a tapered trapezoid section that has a tapered surface inclined within an acute angle with respect to a direction perpendicular to the attaching surface on the outer circumference, and has a tapered front end extending in the perpendicular direction. When the angle of inclination of the attaching surface with respect to the direction orthogonal to the opening and closing direction of the mold is defined as 'α', and the angle of inclination of the tapered surface with respect to the direction perpendicular to the attaching surface is defined as 'β', β−α>0 is satisfied.
