Since the top surface of the member 14 and the bottom surface of the inner panel box 12 are always engaged when the front door 2 is opened and closed, the inner panel box 12 is supported without wobbling, and the inner panel box 12 is supported. Can be held in an accurate position in a stable state.

  The opening stop position at which the inner panel box 12 swings and opens is set by the concave and convex cam surfaces 14a and 12a '. By changing the shape of the cam surfaces, the opening stop position at the specified angle of the front door is set. Thus, the inner panel box 12 can be held at any open stop position. When setting the opening stop position of the inner panel box 12, it is designed so as to be held at an angle that can be easily taken out in consideration of an object (for example, a kitchen knife) accommodated in the inner panel box 12. .

  Next, when the front door 2 is closed again, the lower end frame member 14 is moved together with the front door 2 by swinging the upper end of the front door 2 toward the front frame plate 1a via the first pivotally attached portion. The convex cam surface 14a of the lower end frame member 14 that swings and engages the bottom surface of the inner panel box 12 pushes up the concave cam surface 12a ', and the convex cam surface 14a supports the load of the inner panel box 12. However, the inner panel box 12 is also closed in the state shown in FIG. 3 together with the swinging motion of closing the front door 2 with the locking shaft 15 as a fulcrum.
