Pressed by the bar 510 is moved to the lower side of the receiving member 520 and consequently pulls the wire 30 as a whole.

As the wire 30 is pulled as described above, the pad part 10 to which the wire 30 is connected at regular intervals also acts as a force to be pulled in the lateral direction of the tire 1 to be in close contact with the outer circumferential surface of the tire 1, Finally, the snow chain temporarily fastened to the tire 1 by the fastening part 40 is mounted on the tire 1.

After mounting of the snow chain is completed, the fixing part 540 of the contact means 50 is rotated so that the fixing teeth 541 are engaged with the teeth 511 of the elevating bar 510 so that the elevating bar 510 is engaged. By fixing the, the lifting bar 510 pulling the wire 30 does not flow to prevent the pad portion 10 from being spaced apart from the outer circumferential surface of the tire 1.

Meanwhile, in the detachment method of the snow chain, first, the tire 1 is rotated so that the contact means 50 is located on the upper side of the tire 1.

Thereafter, the lifting portion 540 is rotated to separate the engaged teeth 511 and the fixed teeth 541 to allow the lifting bar 510 to rise. At this time, the wire 30 pulled by the contact means 50 by the tension force generated in the return spring 580 described above is returned to its original state, the lifting bar 510 is raised and the pressing plate 500 connected thereto. It is also spaced apart from the upper surface of the pad portion 10.

Accordingly, the pad portion 10 which is in close contact with the outer circumferential surface of the tire 1 has a play with the outer circumferential surface of the tire 1 due to the loosened wire 30, and the first fastening portion 41 which is fastened and The play between the second fastening portions 42 also occurs.

Since the position of the second fastening portion 42 is relatively lower than that of the first fastening portion 41, the coupling member 421 of the second fastening portion 42 is the same as when snow chain is mounted. It is automatically separated from the locking bar 411 of the first fastening portion 41 by.

Thereafter, the detachment of the final snow chain is completed by separating the fixing means 20 fixed to a portion of the outer surface of the tire 1 from the tire 1.

As described above, the snow chain according to the present invention can be easily mounted and detached, and since most operations can be made automatically and quickly, the snow chain can be shortened and provide convenience to the user.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided.
