By forging a metal material, there is formed a dustproof bootin which a side of an opening end portionformed with a groovefor a dustproof boot is provided with a diameter smaller than that of a side of a piston main body, and a total thereof is provided with a substantially uniform wall thickness, thereafter, by carrying out ironing from a front end of the opening end portionto the piston main body side, the recess groovefor the dustproof boot can be formed by providing a build-up portionat the opening end portion.

A dust-proof boot comprising an internal engaging ring extended from one end of an expansible bellows portion and an external engaging ring provided upwardly thereof and capable of being spread is provided at an extended base of the internal engaging ring with an air flow port for guiding pressure from the inside of the bellows portion into the internal engaging ring. In mounting the dust-proof boot on a support provided with a guide hole, the internal engaging ring of the dust-proof boot is fitted into an internal groove of the support, after which compressed air is supplied from the interior of the bellows whereby the compressed air spreads the external engaging ring via the air flow port and the external engaging ring is fitted into an external groove.
