摘要： The present invention addresses the problem of minimizing the difference between the pressure-receiving surface areas of two gas chambers that are demarcated by a piston unit in a damper device which uses a piston cylinder mechanism. This damper device (20) is equipped with: a cylinder unit (22) having a sliding inner wall surface; a piston unit (26), having a piston head (28), which has an outer diameter part that slides on the sliding inner wall surface of the cylinder unit (22), and divides the interior space of the cylinder unit (22) into a first gas chamber (38) and a second gas chamber (40), a rod (32) extending from the second gas chamber (40) side of the piston head (28), and a closed-end hole (34) which opens toward the first air chamber (38) side of the piston head (28) and extends through the interior of the rod (32) in the direction of the second air chamber (40); and a guide shaft (42) affixed to the first gas chamber (38) side of the cylinder unit (22) and equipped with a tip part (48) having an outer circumferential surface that slides on the inner wall surface of the closed-end hole (34) of the piston unit (26).
