A string type air damper includes a cylinder formed in a tubular shape, defining a guide hole at one end portion thereof, a piston, which moves in the cylinder, a helical spring for biasing the piston toward the other end portion of the cylinder, and a string member guided from inside of the cylinder to outside thereof through the guide hole. The piston and the string member are integrally formed. Since the string member is formed integrally with the piston, unlike a method according to a related art, it becomes unnecessary to form a loop at the base end portion of the string member with a complicated work and form a hook portion at the piston and hook the base end portion of the string member at the hook portion of the piston. Therefore, the string type air damper can be very easily assembled. |
