When the door 2 is light, the door 2 is supported at a relatively upper position. That is, even if the bearing a is mounted at a required height position, the supported position changes according to the weight of the door 2. When removing the door 2 from the cabinet body 1, the door 2 is supported from below,
For example, it is necessary to forcibly insert the tip of a screwdriver between the bearing member d of the bearing member a and the shaft support 5, and when the door 2 is heavy, the workability is reduced.

In view of such a conventional problem, a bearing device according to the present invention has been devised. In particular, the upper and lower sides of one side of a cabinet body or the like having a laterally opened opening are directed vertically. When a door with a pivot that has a pivot at the end is detachably mounted, the lower pivot can always be supported at the same height regardless of the weight of the door. It is an object of the present invention to be able to remove without having to support from below.

In order to achieve the above object, according to the first aspect of the present invention, a pivot shaft protruding from a side end of a door at an axial center inside a cylindrical body having a bottom is provided. In addition to the support shafts facing each other, the bearing tube forming the bearing port of the pivot between the end of the support shaft and the periphery of the support shaft inside the cylindrical body is detachably protruded from the open end of the cylindrical body. Thus, a bearing was provided which was elastically biased toward the other side. The second embodiment exemplifies that the open end of the tubular main body and the tip of the support shaft are located on the same plane.

[0009]

Thus, such a bearing device is mounted by fitting a shaft support projecting a pivot to one end of one side of a door formed of, for example, a sheet glass or the like, and a cabinet body or the like. Attach this to the mounting opening established at the position corresponding to the pivot of the door at the opening of the opening, and push the bearing of the shaft support into the inside of the cylindrical body by pushing the bearing cylinder, thereby The door is forcibly inserted into a bearing opening formed between the distal end and the elastically restored bearing cylinder, and the door is detachably attached to the cabinet body or the like. When the cabinet body or the like has an opening that opens to the side and a vertically oriented door that opens and closes the opening is detachably attached to this opening, it is necessary to attach such a bearing at least to the lower part. Since the distal end of the lower pivot is supported by being supported on the distal end of the support shaft, the lower pivot can always be supported at the same height regardless of the weight of the door.
