PURPOSE:To obtain a styrene resin injection molded article with an abrasion-resisting slide surface by specifying specific abrasion loss. CONSTITUTION:The specific abrasive loss of this article is given by 3mm.<3>/kg.km or less, preferably, 1mm.<3>/kg.km or less. Therefore, this article is made of more inexpensive styrene resin than polyacetal resin or nylon resin, can be molded into one body with the slide surface, even though it is complicated in shape, and is an inexpensive injection molded article with a slide surface excellent in abrasion resistance. For the molding material of this injection molded article is used polyamide copolymer containing 95-10pts.wt., preferably, 90-20pts.wt., further preferably 80-30pts.wt. of aminocarboxylic acid with six or more carbons or lactam or nylon mn salt of m+n>=12 to 10pts.wt. of styrene resin. |
