Description
〔1〕 射出成形により得られる車両用灯具の樹脂成形部品であって、
第1の樹脂成形部と、
第2の樹脂成形部と、
前記第1の樹脂成形部と前記第2の樹脂成形部との間に溝部を有して屈曲成形された屈曲樹脂成形部と、
前記溝部の内側に位置して前記屈曲樹脂成形部の前記溝部を形成する一方の傾斜壁と他方の傾斜壁との間を連結するリブ壁とを備え、
前記リブ壁は、前記射出成形により前記一方の傾斜壁と前記他方の傾斜壁との何れかの傾斜壁の前記溝部を形成する面とは反対側の面に形成されるゲート痕と重なる位置に設けられていることを特徴とする車両用灯具の樹脂成形部品。
〔2〕 前記リブ壁は、前記溝部の底面から前記ゲート痕と重なる位置よりも上方に突出して設けられていることを特徴とする前記〔1〕に記載の車両用灯具の樹脂成形部品。
〔3〕 前記リブ壁は、前記溝部の底面から前記一方の傾斜壁と前記他方の傾斜壁との間に設けられた折り返し部よりも上方に突出して設けられていることを特徴とする前記〔1〕又は〔2〕に記載の車両用灯具の樹脂成形部品。
〔4〕 前記屈曲樹脂成形部は、前記一方の傾斜壁と前記他方の傾斜壁との前記リブ壁と連結される位置での開き角が少なくとも鋭角となる形状を有することを特徴とする前記〔1〕〜〔3〕の何れか一項に記載の車両用灯具の樹脂成形部品。
〔5〕 前記溝部は、前記リブ壁と交差する方向に延長して設けられていることを特徴とする前記〔1〕〜〔4〕の何れか一項に記載の車両用灯具の樹脂成形部品。
