<p>The present invention relates to a door damper for shock absorption, and includes: a damper housing (12) having a fluid storage (14) which stores the oil inside; a piston rod (40) sliding inside the damper housing (12) according to an opening and closing of a door (D); a cover member (22) installed on an opening (24) of the damper housing (12) to prevent the oil from leaking outside; a gasket cover (32) sealing an opening of the fluid storage (14) to prevent the oil leakage; a piston (42) controlling a sliding speed of the piston rod (40) according to the movement of the oil; elastic members (60) applying an elastic force to the piston rod (40) to return the piston rod (40); and a piston guide (16) guiding to allow the oil to move in a constant amount. According to the present invention, the door damper for shock absorption installs an extra metallic piston guide inside the fluid storage to improve the precision of the fluid storage. Accordingly, the precision of the door damper for shock absorption is improved and the defect rate of the door damper for shock absorption is reduced to increase the productivity of the product.</p> |
