装したことを特徴するドアクローザ用ダンパ。 A piston rod has a push rod extending through the shaft center and protruding from one end for operating a damping force adjustment mechanism inside the damper, and a spring is disposed at one end of the piston rod to allow the push rod to be inserted therein and to hold the push rod. Has a stepped insertion hole,
An adjusting screw that engages with the push rod to operate it is attached to one end of the insertion hole, and a bracket having a threaded portion that engages with one end of the piston rod is attached to the other end. Between the tip of the inserted piston rod and the spring, one end comes into contact with the step in the insertion hole and forms a seat for the spring, and the other end comes into contact with the tip of the piston rod to form an oil seal. A damper for a door closer characterized by a collar that forms part of the housing.
