摘要：
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).
