作動式開戸装置。[Claim for Utility Model Registration] A chain is wound around a sprocket fixed to a drive shaft for opening and closing a door, and separate rods that can move forward and backward are connected to one end and the other end of this chain, respectively. In addition, a stopper is provided to restrict the retracted position of each of these rods, and when the rod is moving forward from the retracted position, the advancing rod is always elastically biased in the backward direction. In the constructed door opening device with both internal and external operation, torsion coil springs are provided at one end and the other end of the chain, and these torsion coil springs cause the links at one end and the other end of the chain to move in the bending direction. A door opening device that can operate both inside and outside.
