Since it is a simple configuration provided with the tilting angle restricting means, it is possible to mount the rail to the front and rear columns so as to be tiltable within a certain tilting angle range with much less trouble than before. In addition, the elastic body and the hinge mechanism
It is detachably mounted using bolt mounting grooves and bolts and nuts provided on the rail, making it easy to use the elastic body or hinge mechanism when the elastic body has deteriorated over time or the hinge mechanism has failed. It has the advantage that it can be replaced quickly. Further, since the mounting table is constituted by rails having a bolt mounting groove and a tire fitting groove, it can be manufactured inexpensively by mass production, and can efficiently assemble a parking device. Furthermore, since it has a tire fitting groove, the bicycle tire mounted on the rail is fitted into the tire fitting groove, and by holding the wheels by the supporter, the bicycle can be tilted or standing up. , And can be maintained with high stability. further,
When the tire fitting groove is formed by laminating a large diameter tire for thick tires and a small diameter for thin tires in two layers vertically, a single minimum width rail can be used for a bicycle with a thick tire. The bicycle can be parked on any of the bicycles with thin tires, and the user can easily use the bicycle without selecting a parking position in consideration of the diameter of the tire of his own bicycle, which is convenient.

The above-mentioned elastic body is supported by the support 13 and the rail 1.
The structure to be detachably attached to 5 and the shape and structure of the elastic body are not limited to those described above. That is, for example, the installation position of the bolt insertion groove of the rail is not limited to the one that opens to the bottom surface of the rail. It is good also as what opens on the side of a rail. The bolt of the elastic body is not limited to being screwed into the upper surface of the column. The stabilizer 25c is formed in a U-shape, and a bolt that horizontally penetrates the side surface and the side surface of the column 13 and a nut that is fastened to the bolt. Can also be used.
