Claims

[Scope of Claim for Utility Model Registration] (1) A horizontal rail 2 is fixed to the storage body 1 above the door 3, and two left and right wheels 4 and 5 installed at the upper end of the door 3 are mounted on the rail 2. The rail 2 is provided with two left and right recesses 6 and 7 formed diagonally downward so as to approach the storage body 1 side, and when the door 3 is in the fully closed position, the wheels 4 on one side are dropped into the recesses 6 on one side. At the same time, in a self-weight sealing device such as a refrigerator door, in which the wheel 5 on the other side is dropped into the recess 7 on the other side to bring the door 3 closer to the refrigerator main body 1, the wheel 5 on the one side comes into contact with the circumferential surface of the body of the wheel 4 on the one side. A self-weight sealing device for a refrigerator door or the like, in which a support wall portion 8 for preventing the recess 4 from falling is provided adjacent to the edge of the other recess 7. (2) The wheel mounting part of the rail 2 is placed on the front and rear inclined surfaces 9,
10 to have a chevron-shaped longitudinal section, and recesses 6 and 7 having an arc-shaped longitudinal section are provided in the front inclined surface 9.
, 10, the front and rear large diameter flange portions 11 of the wheel 4,
A medium-diameter trunk 13 and a small-diameter trunk 14 are provided front and rear between 12, and the medium-diameter trunk 13 is brought into contact with the front inclined surface 9. A small-diameter body part 17 and a medium-diameter body part 18 are provided front and back between the diameter flanges 15 and 16, and the medium-diameter body part 17 is brought into contact with the rear inclined surface 10, and the support wall part 8 is connected to the other concave part 7. Claim (1) wherein the upper edge of the recess is provided so as to project in the transverse direction of the recessed portion 7 so as to match the surface position with the inclined surface 9, and the medium-diameter body portion 13 of the wheel 4 is brought into contact with the support wall portion 8. Dead weight sealing device as described. (3) The self-weight sealing device according to claim (1), wherein the wheels 4 and 5 are formed to have the same dimensions, and are attached to the axle 19 by being reversed left and right.
