ステーダンパ。 A piston is slidably housed inside a cylinder filled with gas, a piston rod connected to the piston is slidably protruded from the cylinder, and the protruding end and the base end of the cylinder are connected to one another through a bracket. In a stay damper for a swing door that supports the opening and closing of the swing door by locking one side to the swing door and the other side to the surrounding frame, the piston rod is supported so that it can slide freely, and when the tip of the piston rod collides with the bracket, the piston rod is locked inside the cylinder. A bushing that is displaced in the axial direction toward the piston rod is held at the tip of the cylinder, and a gas passage is formed by passing through this bushing vertically, and a sealing member that is deformed and separated from the piston rod as the bushing is displaced in the axial direction is attached adjacent to the bushing. A stay damper for a swing door, characterized in that the stay damper is interposed between a cylinder and a piston rod.
