Patent ID: 7700177

Claim:
A resin molded component for an internal combustion engine comprising: a single flange having a through-hole, wherein a concave portion is formed on a surface of the flange that faces a component used in the internal combustion engine on which the flange is fitted; the concave portion is formed upstream of an area in the periphery of the through-hole where, during a molding process of the resin molded component, a greater amount of molten resin material flows from a bottom portion of the concave portion into an area around the through-hole, than an amount of molten resin material that flows from a thickness of the resin material in a thinnest portion of a wall portion of the concave portion into a meeting portion of the flange to minimize formation of a weld line; and a thickness of the resin material in the bottom of the concave portion is greater than the thickness of the resin material in the thinnest portion of the wall of the concave portion.
