DAMPER

摘要

A damper that includes a piston reciprocally movable in a cylinder thereby dividing an interior of the cylinder into a first chamber located at an open end side and a second chamber located at a closed end side, a piston rod having a distal end to which the piston is connected and a rear end side protruding outward from the open end of the cylinder, a rod guide fixed to the open end of the cylinder and having a through hole through which the piston rod is reciprocally movable, and a seal which is provided in the rod guide so as to be located at a position spaced away from an outer end of a sliding surface of the through hole to the first chamber side by a distance longer than a maximum stroke width of the piston rod.

1. A damper comprising:
a cylinder which is bottomed and has an open end and a closed end, the cylinder being filled with a fluid; a piston reciprocally movable in the cylinder thereby dividing an interior of the cylinder into a first chamber located at the open end side and a second chamber located at the closed end side; a piston rod having a distal end and a rear end, the piston being connected to the distal end, the rear end side protruding out of the open end of the cylinder; a rod guide fixed to the open end of the cylinder and having a through hole through which the piston rod is reciprocally movable; and a seal which is provided in the rod guide so as to be located at a position spaced away from an outer end of a sliding surface of the through hole to the first chamber side by a distance longer than a maximum stroke width of the piston rod, the sliding surface contacting an outer periphery of the piston rod.
