PROBLEM TO BE SOLVED: To provide a gear made of a resin which excels in dimensional accuracy and long-term strength. SOLUTION: The gear is obtained by molding a resin composition to be obtained by compounding 10 pts.wt. resin component comprising (A) 80-96 wt.% polyamide obtained by polymerizing a diamine containing≥70 mol% m- xylylenediamine and a carboxylic acid containing≥70 mol% 6-12Cα,ω-aliphatic dicarboxylic acid, (B) 2-10 wt.% unsaturated organic acid-modified polyolefin, and (C) 2-10 wt.% ultra-high-molecular-weight polyethylene with (D) 40-250 pts.wt. glass fibers.
