徴とするスイングドア用ステーダンパ。 A piston is slidably housed in a cylinder filled with gas, the piston is supported by the tip of a piston rod that is slidably inserted into the cylinder in the axial direction, and one of the base ends of the piston rod and cylinder is connected to a swing door. In a stay damper for a swing door that assists in opening and closing the swing door by locking the other end to the surrounding frame, a through hole is formed through the piston rod vertically to communicate the inside and outside of the cylinder, and the push rod is inserted into this through hole. A seal is applied to the outer periphery of the push rod that slides into contact with the through hole to shut off gas flow within the through hole, and a seal that is larger than the seal diameter is attached to the through hole behind this seal. A stay damper for a swing door characterized by forming a large-diameter portion.
