シリンダ装置。 A cylinder body in which a cylinder hole into which a piston is slidably fitted is formed, an annular groove formed in the outer periphery of the cylinder hole opening of the cylinder body, one end of which fits into this groove and the other end of which fits into the piston. In the cylinder device, the cylinder device includes a boot that has been worn, and a retaining ring that is fitted onto the outer periphery of the one end of the boot to prevent it from coming out of the groove, the one end of the boot having:
The outer peripheral surface shape of a portion that fits into the groove and a portion that extends from this portion along the cylinder body are made to match, and the retaining ring has an inner periphery that is continuous in the circumferential direction and substantially matches the outer peripheral surface shape of the boot. A cylinder device having a surface shape, and provided with a protrusion that rides over the retaining ring when the boot is attached to the boot and engages in the opposite direction.
