PROBLEM TO BE SOLVED: To allow a heat insulating door of a vending machine locked in closed state to turn into open state smoothly. SOLUTION: When a heat insulting door is in a closed state, a rotating bent arm 12 contacts a closing direction pressurizing part 23 and presses the insulating door in the closing direction. While the heat insulating door is pressed in the closing direction, an axis part 11 is raised upward along the tilted surface 22a and guides the heat insulating door to the position where it is moved up and down and fixes the position. When a heat insulating door is in an open state, the rotating bent arm 12 contacts an open direction pressurizing part 24 and presses the insulating door in the open direction. While the heat insulating door is pressed in the open direction, the axis part 11 is lowered downward along the tilted surface 22a and releases the fixation of the position. By this arrangement, when the heat insulting door is in a closed state, the operation of opening the heat insulating door is executed smoothly since the weight generated when the edge for opening and closing the heat insulating door is raised is not transferred from the axis part 11 to a handle 13 through the bent arm 12.
