[Issues of background technology]
In the anti-slip device as described above, the anti-slip body determines the size in accordance with the size of the tire of the automobile.
When the car becomes large, the tire becomes large. Large tires have a large outer diameter and a wide width. Further, when the automobile becomes large, the tire is not a single wheel but a double wheel in which two tires are concentrically connected. Multi-wheel tires have a very wide overall width.

  In the anti-slip device, the anti-slip body wound around the large-diameter tire has a long tire circumferential direction. The anti-slip body fitted into the wide tire has a wide width. The anti-slip body that covers both tires of a compound wheel is very wide. When the tire becomes large, the anti-slip body becomes large. The non-slip body is made of steel, and when it becomes large, the mass becomes several tens of kg.

  The anti-slip device stores a predetermined number of anti-slip bodies in a fixed position of an automobile or a garage when not in use. This storage position is away from the tire position of the automobile. When attaching or detaching the non-slip device, the operator carries the anti-slip body by hand. The antiskid device is often attached and detached outdoors under snow.

  However, if the anti-slip body is large and has a mass of several tens of kilograms, it is not easy for an operator to carry it alone. It is difficult for an operator to carry a large heavy slipper in the snowy outdoors.
