Claim:
A production method for a stabilizer link, comprising: a subassembly forming step in which a subassembly having a stud ball, a main body of a ball seat, and a housing is formed, wherein in the subassembly forming step, a space is formed between a bottom side of a side surface of the main body and a bottom side of an inner surface of the housing; a cavity forming step in which a die is provided to an outer surface of a bottom side of the housing in the subassembly and a cavity is thereby formed; and an injection molding step in which injection molding is performed such that a reinforced resin is injected into the cavity and the space, and a fixing portion of the ball seat is thereby found so as to cover the bottom side of the side surface of the main body, wherein in formation of the main body of the ball seat, a first fit shape including at least one of a recess and a protrusion is formed at the bottom side of the side surface of the main body, and in formation of the fixing portion of the ball seat, a resin including a reinforcing agent is used as the reinforced resin, the reinforced resin is flowed to an outer surface of the side surface of the main body through a hole of the housing, so that a second fit shape fitted to the first fit shape is formed at the fixing portion, a projection projecting from the hole of the housing to an external is formed at a bottom of the fixing portion, and the projection is formed to have a shape engaging with the outer surface of the bottom of the housing.
