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, a predetermined portion of the chain that slackens when the sprocket rotates in a predetermined direction from a neutral position and the door opens inward, and a predetermined direction when the sprocket rotates from the neutral position to the predetermined direction. One end and the other end of a wire, the middle part of which is wound around a guide member provided at a predetermined location, are connected to a predetermined part of the chain that becomes slack when the door is opened outward by rotating in the opposite direction. A door opening device that operates both inside and outside, characterized by being fixed to each other.
