扉枢支装置。A door having a frame-shaped sealing member disposed on the inner peripheral edge thereof is pivotally supported to be openable and closable at an opening in a storage main body, which includes a pivot body attached to the storage body and a pivoted body attached to the door. A shaft and a guide pin are formed on one side, and a long groove shape extending in the front-rear direction is formed on the other side, and the pivoted body is moved forward in order to fit with the shaft and move it forward when the door is opened. In addition to forming a shaft fitting groove to be moved, the groove is shaped like a cutout and is fitted with the guide pin to prevent rotation of the pivoted body about the shaft when the pivoted body is moved. A guide groove is formed that allows the rotation when the guide pin is disengaged, an arcuate guide surface is formed on one of the pivot body and the pivoted body, and this guide surface is slidably contacted with the other. A rotation guide is formed that holds the fitting position of the shaft in the shaft fitting groove after the pivoted body has moved and guides the rotation of the pivoted body about the shaft, and further A storage door pivoting device characterized in that a toggle mechanism is provided between the body and the pivoted body to apply a door opening force when the door is separated from the storage original 4 and to apply a door closing force when approaching the storage original 4.
