摘要： There is provided a processing method of a tube body comprising the steps of: a tube-expanding step wherein a base tube is partially retained with a chuck unit having a rotational function, and a mandrel is pressed in to an end portion of the base tube so as to expand the end portion of the base tube; and a rotation ironing step wherein the chuck unit rotates the base tube together with the mandrel, a roller die is pressed against an outer-periphery surface of the end portion of the base tube and the roller die is moved with respect to the base tube and in an axial direction thereof so as to deform an inner-periphery surface of the end portion of the base tube into a shape corresponding to an external shape of the mandrel.

摘要： A piston connected with a piston rod is fitted in an outer tube having a hydraulic fluid sealed therein, with the piston rod projecting out of the outer tube. A seal part for the piston rod includes a rod guide, a seal case, an oil seal, a dust seal and a securing member, which are inserted into an end portion of the outer tube and secured by first and second staked portions. The sliding part of the piston rod is sealed with the rod seal and a seal lip of the oil seal. The area between the seal case and the outer tube is sealed with an O-ring and a seal member. The pressure resistance of the seal part can be increased to a considerable extent by two-point staking by the first and second staked portions and two-stage sealing by the rod seal and the oil seal.
