[Object] An object of the present invention is to provide a molded product which retains an excellent characteristic of a crystalline polyamide-type resin composition and which has a durability against sliding where the change in appearance on the slid surface is small upon the tens of thousands of repeated sliding under high-load, as well as an excellent mechanical strength and moldability. [Constitution] A crystalline polyamide-type resin composition, characterized in that , to 100 parts by weight of a crystalline polyamide resin composition comprising 50 to 90% by weight of crystalline polyamide resin (A) where relative viscosity of said resin dissolved in 96% sulfuric acid is not less than 3.5 and 50 to 10% by weight of a crystalline polyamide resin (B) where melting point is lower than melting point of the above crystalline polyamide resin (A) by 20°C or more and relative viscosity of said resin dissolved in 96% sulfuric acid is not more than 3.6, 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 is contained. A door checker for automobiles, characterized in that , said door checker is prepared from said crystalline polyamide-type resin composition.
