Summary:PURPOSE:To heighten the sealing capacity of a shock absorber with an electroviscous fluid filled therein by providing a closed lubricating oil chamber, surrounding a piston rod, on the opposite side to a piston, with a bearing placed in between. CONSTITUTION:A lubricating oil chamber 30 between a main seal 15 and a sub-seal 16 is always filled with lubricating oil and held to the specified pressure by a bladder 31. Lubricating oil is always in contact with the respective oil lips 15A, 16A of the main seal 15 and sub-seal 16 so as to form an appropriate oil film on the sliding face. Micro grain is thus separated from an electroviscous fluid, leaking out from a cylinder 1 through a bearing 14, by a dust lip 16B most on the bearing 14 side. The micro grain of the electroviscous fluid can be thereby prevented from going over the bearing 14 to leak outside of a shock absorber, and the lubricating ability of a piston rod 13 to the bearing 14 is improved.
