Claim Text:
1. A fuel-resistant resin plastic body comprising: a polyacetal resin composition comprising a polyacetal resin, a hindered phenol antioxidant and a fatty acid calcium salt, wherein the polyacetal resin is a copolymer containing a monomer having an oxymethylene group as a constitutional unit and an additional constitutional unit, the additional constitutional unit is an oxy C2-6 alkylene unit selected from the group consisting of an oxyethylene group, an oxypropylene group and an oxytetramethylene group, the hindered phenol antioxidant is tris-(3,5-di-t-butyl-4-hydroxybenzyl)-isocyanurate or 1,3,5-tris(4-t-butyl-3-hydroxy-2,6,-dimethylbenzyl)isocyanuric acid, the fatty acid calcium salt is a stearate or stearic acid derivative, in the polyacetal resin composition, the content of the hindered phenol antioxidant is from 0.1 parts by weight to 0.6 parts weight with respect to 100 parts by weight of the polyacetal resin, and in the polyacetal resin composition, the content of the fatty acid calcium salt is from 0.01 parts by weight to 2.0 parts by weight with respect to 100 parts by weight of the polyacetal resin.
