Forced extraction molded article, polyarylene sulfide resin composition, and method for producing forced extraction molded article

Abstract

A forced extraction molded article that can prevent damage during forced extraction is provided. The force extraction molded article (1) is formed of a polyarylene sulfide resin composition so as to include a cylindrical portion, wherein the cylindrical portion (10) has at a forward end portion a bulge (11), and an inner surface including a step in the outer diameter direction at the forward end portion, a portion excluding the step has a gradient such that the inner diameter of the cylindrical portion increases toward the forward end portion, and equation (a) below using a thickness D2 between a connection portion at the step on the inner surface of the cylindrical portion and the outer surface excluding the bulge, a height D4 of the step, and a height Dt of the gradient excluding the step on the inner surface of the cylindrical portion is satisfied.
