INJECTION MOLDED ARTICLE AND PRODUCTION METHOD THEREOF

摘要

Provided is an injection molded article having a junction surface where side end surfaces of two thermoplastic resin members are bonded by injection molding one of the members onto the side end surface of the other member, wherein (a) a junction line where a longitudinal cross sectional surface of the molded article cross crosses with the junction surface is defined by a first junction line segment extending from the front surface toward the inside of the molded article and having a terminal on the inside, a second junction line segment extending from the back surface toward the inside of the molded article and having a terminal on the inside, and a third junction line segment connecting the terminal of the first junction line segment and the terminal of the second junction line segment, as well as (b-1) directions (A) of the respective junction line segments with respect to the normal line of the front surface or the back surface of the one thermoplastic resin member are different and the direction (B) of the third junction line segment is inclined with respect to the normal line, or (b-2) the directions (A) are the same in the first junction line segment and the second junction line segment and are different between the first junction line segment and the third junction line segment and the direction (B) is inclined with respect to the normal line.
