RESIN MOLDED BODY AND METHOD FOR MANUFACTURING RESIN MOLDED BODY

Provided is a resin molded body formed by injection molding. The resin molded body has a weld line provided in a resin-joint portion (weld), and has excellent strength and reliability. The resin molded body is formed with a single weld connecting: a first bent portion; a second bent portion bent in a direction opposite to a bend direction of the first bent portion; a first linear portion connecting the first bent portion and the second bent portion; a third bent portion bent in a direction opposite to a bend direction of the second bent portion; a second linear portion connecting the second bent portion and the third bent portion; a fourth bent portion bent in a direction opposite to a bend direction of the third bent portion; and a third linear portion connecting the third bent portion and the fourth bent portion. 本发明针对通过射出成型的树脂成型体，提供一种在树脂的接合部(熔接部)具有熔接线的强度和可靠性优异的树脂成型体。本发明的树脂成型体中形成1个熔接部(线)，该熔接部具有第一弯曲部、与所述第一弯曲部的弯曲方向相反地弯曲的第二弯曲部、连接所述第一弯曲部和所述第二弯曲部的第一直线部、与所述第二弯曲部的弯曲方向相反地弯曲的第三弯曲部、连接所述第二弯曲部和所述第三弯曲部的第二直线部、与所述第三弯曲部的弯曲
