Description

本開示に係る樹脂成形体は、一部に穴（３１）が形成されている樹脂成形体であって、成形時においてゲートから溶融樹脂が流入した部分であるゲート部（ＧＰ）と、穴において、対向する内壁面同士を繋ぐように形成された内柱部（６０Ｂ）と、を備える。内柱部は、ゲート部から穴に向かう方向である樹脂流れ方向、に沿って伸びるように形成されている。内柱部は、樹脂流れ方向に対し垂直な断面の断面形状が、当該断面の位置によって変化する一方、樹脂流れ方向に対し垂直な断面における断面積が、当該断面の位置によって変化しない形状となっている。 Molded resin according to the present disclosure is a resin molded body bore (31) in a portion is formed, a gate portion (GP) is a portion melted from the gate resin has flowed during molding, in the hole And an inner column portion ( 60B) formed to connect the opposing inner wall surfaces. The inner pillar portion is formed to extend along the resin flow direction which is a direction from the gate portion toward the hole. In the inner column, the cross-sectional shape of the cross section perpendicular to the resin flow direction changes with the position of the cross section, while the cross-sectional area in the cross section perpendicular to the resin flow direction does not change with the position of the cross section ing.
