PROBLEM TO BE SOLVED: To provide a door opening/closing mechanism capable of opening/closing a door with ease and which is stable in the opened/closed state of the door and easily usable. SOLUTION: The door opening/closing mechanism 60a is chiefly composed of an arm 61 in which the front end is rotationally fitted to the back face of a sliding door 19 through an axis 62 and a weight member 64 which is rotationally fitted through an axis 65 in a support plate 6 of a containing case 3 and rotationally fitted through an axis member 63. The arm 61 is opened/closed so as to hold up the sliding door 19 around the center of the hinge 7 by receiving an external force added in order to move a vertically moving shelf through a rear support link 14a and the weight member 64. According to it, as the position of the gravity center G of the arm 61 is rotated so as to be changed around the axis 65, with regard to the weight member 64, the urging direction and magnitude for the sliding door 19 by the rotary force of the weight member 64 change.
