ELBOW MEMBER

To provide an elbow member made of a metallic resin and improved in appearance quality while suppressing cost increase.SOLUTION: An elbow member such as a second elbow member 22 has two cylindrical receiving ports to which rain gutter structural members are connected and an elbow body to which the two receiving ports are connected, and is made of a metallic resin. The elbow member has a thickness of 1.5 to 5.0 mm, and gate traces are formed on a plane including the central axes of the two receiving ports in an elbow body. When seeing the inner surface of the elbow body from one receiving port side of the two receiving ports, a thin wall region 35 having a thickness of 1.5-2.9 mm is provided in a range including a circular region having a diameter of 20 mm with the gate trace 34 as a center. In a cross-sectional shape cut in a plane, the inclination angle of the inner surface of a thickness-varying part to the inner surface of the thick wall part in a part where the thickness is varied toward a thick wall part 31 from the outer edge of a thin wall part 33 is 45 degrees or less.SELECTED DRAWING: Figure 4 【課題】メタリック樹脂で形成され、かつ、コスト増大を抑制しながら、外観品質を向上できるエルボ部材を提供する。【解決手段】第２エルボ部材２２等のエルボ部材は、雨樋構成部材が接続される２つの筒状の受け口と、２つの受け口を接続するエルボ本体とを有するメタリック樹脂製である。エルボ部材は、厚さが１．５ｍｍ以上、５．０ｍｍ以下であり、ゲート痕が、エルボ本体において、２つの受け口の中心軸を含む平面上に設けられ、２つの受け口の一方の受け口側からエルボ本体の内面を見た場合に、ゲート痕３４を中心として直径２０ｍｍ以上の円形領域を含む範囲に、厚さが１．５ｍｍ以上、２．９ｍｍ以下である薄肉領域３５が設けられ、平面で切断した断面形状において、薄肉部３３の外端から厚肉部３１に向かって厚さが変化する部分における、厚肉部の内面に対する厚さ変化部分の内面の傾斜角度が４５度以下である。【選択図】図４
