The invention provides a crystalline polyamide-type resin composition comprises (a) a crystalline polyamide resin composition comprising (i) 50 to 90% by weight of crystalline polyamide resin (A) having a relative viscosity in 96% sulfuric acid of not less than 3.5 and (ii) 50 to 10% by weight of a crystalline polyamide resin (B) having a melting point lower than the melting point of polyamide resin (A) by 20&#xb0; C. or more and a relative viscosity dissolved in 96% sulfuric acid of not more than 3.6, and (b) 1 to 10 part(s) by weight of a modified polyolefin resin (C) having a reactive functional group being able to react with the terminal group and/or main-chain amide group of the polyamide resin. The invention also provides a door checker for automobiles prepared from the crystalline polyamide-type resin composition.

Crystalline polyamide-type resin composition

An electrically conductive resin composition of a polyamide type, characterized in that, (A) 95 to 40% by mass of polyamide resin, (B) 5 to 30% by mass of electrically conductive carbon black, (C) 10 to 40% by mass of an ethylene-&#x3b1;-olefin copolymer having a reactive functional group which is able to react with a terminal group of the polyamide resin and/or an amide group of the main chain and (D) 1 to 10% by mass of a high-density polyethylene resin are compounded; the polyamide resin (A) forms a continuous phase; the ethylene-&#x3b1;-olefin copolymer (C) in particles having an average particle diameter of not more than 2 &#x3bc;m is present by being dispersed in the continuous phase of the polyamide resin (A); and not less than 80% by mass of the electrically conductive carbon black (B) is present by being dispersed in the polyamide resin phase (A) which is a continuous phase, as well as a cap for fuel tank comprising it.
