Abstract

PURPOSE:To prevent a piston from being fastened with rust, by making the inside diameter of a lip part between a dust boot fitting groove and a piston seal fitting groove larger than that of a cylinder chamber to provide a step part at the cylinder chamber. CONSTITUTION:A groove 14 for fitting a dust boot 13 and another groove 16 for fitting a piaton seal 15 are provided at the mouth of the cylinder chamber 10. The lip part 17 is provided between the grooves 14, 16. The outsides diameter of the lip part 17 is made by 2l larger than that of the cylinder chamber 11. Since there is a relatively large gap between the piston 11 and the lip part 17, the piston is prevented from being fastened with rust when the waterproof function of the dust boot 13 deteriorates and the lip part 17 rusts.
