Abstract: The present invention provides an impeller formed from a resin composition having high tensile strength and specific strength in a high-temperature environment, and having high dimensional accuracy and excellent fire resistance. The impeller according to the present invention is formed from a resin composition containing (A) an aromatic polycarbonate-based resin (component A) and (B) a liquid crystal polyester resin (component B), and containing, on the basis of a total of 100 parts by weight of component A and component B, (C) 3-40 parts by weight of a halogenated carbonate compound (component C), (D) 0.1-3 parts by weight of a drip inhibitor (component D), (E) 25-150 parts by weight of glass fibers and/or carbon fibers (component E), (F) 0.1-8 parts by weight of an epoxy resin (component F), and (G) 0.01-3 parts by weight of a phosphorus-based stabilizer (component G), wherein the weight ratio of component A and component B [(A)/(B)] is 98/2 to 60/40.

Abstract: A resin composition which comprises polylactic acid, does not release an isocyanate group at the time of production and has excellent hydrolysis resistance and a low environmental burden. The resin composition comprises: (A) 100 parts by weight of a resin component (component A) containing polylactic acid (component A-?); (B) 0.001 to 10 parts by weight of a compound (component B) having one carbodiimide group and a cyclic structure in which first nitrogen and second nitrogen are bonded to each other via a bonding group, the cyclic structure consisting of 8 to 50 atoms; and (C) 0.001 to 2 parts by weight of at least one antioxidant (component C) selected from the group consisting of a hindered phenol-based compound, a phosphite-based compound, a phosphonite-based compound and a thioether-based compound.
