Abstract

Abstract A polyamide resin molding composition having excellent antivibration property comprising a polyamide resin obtained from xylylenediamine and an alpha,omega-­straight-chain aliphatic dibasic acid and optionally, mica having an average particle diameter of not more than 200 micrometers and glass fibers, the proportion of mica being 20 to 55 % by weight, the proportion of the glass fibers being 15 to 55 % by weight, and the total pro­portion of the mica and glass fibers being 30 to 70 % by weight.
