Abstract

PURPOSE:To diminish a transmission of friction heat of a brake shoe of a vehicle in order to prevent boiling of brake liquid and breakage of a seal by molding synthetic resin and bonding it to steel in a sliding part or the like which need not to be strong of a piston for expanding the brake shoe. CONSTITUTION:A brake shoe engaging member A consisting of a cylinder 6 with an opening end 4, the inlaid groove 5 of a boot 45 and an internal thread 3 is partially thickened to form a piston, with a sliding part 7, the inlaid groove 2' of a seal 46 and an opposite end 8 simultaneously with synthetic resin or fiber reinforced plastics. A washer 9 is set at a terminal 3' of the internal thread part so that molding material M does not enter the internal thread 3 then. Also, one or more lines of a groove 6' is formed in order to bond molding material M tightly.
