As shown in FIG. 5, the wire 53 can be moved relative to the handle 56 in the line direction of the wire 53. That is, the wire 53 is inserted through the coupling portion 56b of the handle.
With this configuration, the wire 53 passed through the opening 13 of the wheel 10 is moved in the linear direction so that both ends of the wire 53 reach the left and right sides of the outer periphery of the tire 14 respectively. The hook 21f at one end and the link 21r at the other end can be easily brought close to the tip hook 54 and the tip ring 55 at both ends of the wire 53 (see FIG. 6).

  As the wires 2 and 53, appropriate ones can be adopted. For example, a wire, a piano wire, a wire rope, etc. can be adopted. Moreover, if it has appropriate intensity | strength and rigidity, a synthetic resin wire can also be employ | adopted. It is desirable that the wire has rigidity and elasticity that can push the hook 3 (54) at the tip or both ends and the tip ring 55 toward the outer periphery (work areas P1, P2) of the tire 14. . Within that range, the thickness and length can be set. For example, in the case shown in FIG. 1, a metal wire rope having a thickness of about 2 to 6 mm and a length of about 50 to 70 cm can be employed. In the case shown in FIG. 5, a metal wire rope having a thickness of about 2 to 6 mm and a length (full length) of about 80 to 100 cm can be adopted.

  The tip hooks 3 and 54 may each have an appropriate configuration. In this embodiment, a snap hook is used.

The handle 4 shown in FIG. 1 is formed by fixing the other end of the wire 2 in a loop shape and fixing with a caulking metal fitting 5, but a T-shaped handle 56 can also be adopted as in the case of FIG. 5.
The T-shaped handle 56 may be of a size that does not easily pass through the normal opening 13 and can easily pull the wire 53. For example, the grip portions 56c and 56c have a total length of about 10 to 20 cm, and the connection portion 56b has a length of 3 to 7 cm. To the extent. The grip portion 56c is preferably cylindrical.
In this embodiment, a pulley 57 is provided in the connecting portion 56b in order to facilitate the movement and drawing work of the wire 53 in the linear direction.

  The tip ring 55 shown in FIG. 5 is formed by forming the other end of the wire 53 in a loop shape and fixing with a caulking metal fitting 55c, but a ring member which is a separate member may be provided.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately modified within the scope of the gist of the present invention.
For example,
When a hook is provided instead of the link 21r on the other end side of the chain, a tip ring can be provided instead of the tip hook 3 (54) provided at the wire tip. When a ring is provided instead of the hook on one end side of the chain, a tip hook is provided instead of the tip ring 55 at the wire tip. That is, the tip hook and the tip ring at the tip of the wire can be appropriately selected depending on whether the end of the tire chain to be attached is a hook or a ring.
