Abstract: Providing a damper which can prevent leak of the fluid filling a cylinder and can maintain a proper reaction force and damping characteristic.
A damper includes a piston (20) reciprocally movable in a cylinder (10) thereby dividing an interior of the cylinder (10) into a first chamber (A) located at an open end (11) side and a second chamber (B) located at a closed end (12) side, a piston rod (30) having a distal end (31) to which the piston (20) is connected and a rear end (33) side protruding outward from the open end (11) of the cylinder (10), a rod guide (40) fixed to the open end (11) of the cylinder (10) and having a through hole (44) through which the piston rod (30) is reciprocally movable, and a seal (49) which is provided in the rod guide (40) so as to be located at a position spaced away from an outer end (Z) of a sliding surface (47) of the through hole (44) to the first chamber (A) side by a distance longer than a maximum stroke width (S) of the piston rod (30).

Abstract: Provided is a damper capable of reducing cost and eliminating a problem of liquid leakage.
A damper (D1) of the present invention includes: a damping portion (A1) that exerts a damping force by using a granular material at a time of extension and contraction; and an elastic portion (E1) that exerts an elastic force at the time of extension and contraction, wherein the damping portion (A1) is coupled to the elastic portion (E1) such that the damping force and the elastic force are exerted in parallel.

Abstract: Provided is a damper that exerts a damping force with a simple structure using elastically deformable granular bodies.
The damper includes a cylinder (10), a piston (30), a rod (50), a rod guide (70), and a plurality of granular bodies (90). The piston (30) is housed in the cylinder (10) and reciprocates in the central axis direction of the cylinder (10). The rod (50) is connected to the piston (30). The rod (50) extends in the central axis direction of the cylinder (10) and protrudes to an outside from an open end (11) side of the cylinder (10). The rod guide (70) is fixed to the open end (11) of the cylinder (10). The rod guide (70) has a through hole (70A) which penetrates in the central axis direction of the cylinder (10) and through which the rod (50) is reciprocably inserted. The granular bodies (90) are elastic bodies each having a spherical shape. The granular bodies (90) are filled in the cylinder (10).
