The present invention relates to a damper which can perform a stable operation with an excellent damping effect using a more simple structure, and has improved durability. According to embodiments of the present invention, the damper comprises: a main body having one or more supply holes for supplying vacuum pressure in one side; one or more covers having one or more opened through-holes formed in one side, and forming one or more receiving spaces when the cover is coupled to the main body; and one or more rods of which one end is exposed to the outside through the through-holes, and the other end is installed to be movable back and forth inside each of the receiving spaces. Each of the rods absorbs vibration of external force by vacuum pressure supplied to the inside of the receiving space from the supply holes when the external force is transferred through the one end exposed to the outside. |
