リンダ型エアダンパ。 A piston rod is attached to the cylinder body so as to be slidable in the axial direction, and a first air chamber and a second air chamber are formed in the cylinder body, and both air chambers are provided in the piston rod. A cylindrical air damper having a communication passage that opens in the axial direction with one end facing the head side and communicates with the communication passage through a porous member having a large number of ventilated pores interposed in the communication passage. A cover having a shielding part that covers an opening at one end and a wall surface around the opening, a communication hole provided in the shielding part so as not to face the opening at one end of the communicating path, and a mounting part provided integrally with the shielding part. is attached to the piston at the mounting portion such that a predetermined gap is formed between the shielding portion and the opening at one end of the communication path and the wall surface around the same, and the wall surface facing the communication hole. A cylinder type air damper characterized in that a required recess is formed in the cylindrical air damper.
