Purpose: the present invention provides the polyamide resin compositions for vehicle chair, have a low toxicity and inhibit in smog and improve in flame retardancy. Construction: polyamide resin composition includes a polyamide; By the 4-30 wt% for the fire retardant based on melamine cyanurate that formula 1 represents; The 0-20 wt% of reinforcing, with 200 or less one specific optical densities (Ds), 35 or less one fire propagation index (YES), 28 or more a limit oxygen index (LOI), 3.0 or less one toxicity (R values), 4 kgcm/ centimetres or more of impact strengths and 1, a flexural strength of 000 kilogram/cm2 or more. Preferably polyamide is at least one selected from polyamide 6 or polyamide 66, has 1.5-3.0 (20 deg.The solution of the polymer of C, 1 g in 100 ml, 96% sulfuric acid) a relative viscosity; Reinforcing is glass fibre, an inorganic material or their mixture. Inorganic material is preferably at least one and is selected from group comprising clay, talcum, wollastonite, synthetic mica and graphite.
