By tightening 7), the inner and outer ends of each of the required number of anti-slip members arranged in parallel at appropriate intervals in the circumferential direction of the tire are directed toward the center of rotation of the tire, and each anti-slip member is attached to the tire. The outer peripheral surface of the tire was kept in close contact with each other so that each of the non-slip members did not float up from the outer peripheral surface of the tire during traveling.

However, the tightening operation described above when connecting the ends of the outer connecting rope of the conventional anti-slip device is performed by the wearer directly gripping the end of the outer connecting rope. Since the connecting force is not enough, the connecting rope loosens during running and the anti-slip device floats above the tire, noise is generated due to vibration, and the tire, anti-slip device,
There was a risk that the car body would be damaged.

<Technical problem to be solved by the invention> The present invention has been made in view of such conventional circumstances, and by utilizing the lever principle, a tightening operation with a sufficient tightening force can be performed even by the force of a person. An object is to provide a tightening device for a tire slip stopper.

The anti-slip device in which the tightening devices (A ₁ ) to (A ₄ ) are used is
As shown in FIG. 10, it may have a structure in which a hook portion (14'b) is projectingly provided at one end of a support portion (14'e) formed with a connector (14 ') in a shape, and in this case, an operating portion ( The belt-shaped part (17'a) of 17 ') is engaged with the support part (14'e) and folded back to be used. The hook part (14') of the connector (14 ') is used.
b) The connecting loop (1 ') on one end of the outer connecting rope (11')
6 ') is hooked, and the hook portion (21) provided at the tip of the operating portion (17) can be hooked on the hooking protrusion (3) of the tightening device (A ₁ ).

The anti-slip device to which the fastening device of the present invention is applied is not limited to the ladder type described above, and may be a net type, a metal chain type, or the like.

<Effects of the Invention> Since the tightening device of the present invention is configured as described above, the following operational effects are obtained.

When attaching the anti-slip device to the tire, after winding the anti-slip member around the outer surface of the tire in the circumferential direction, hook one end of the connecting rope to the hooking protrusion on the surface of the rotating operation rod to keep that state. Meanwhile, the hooking metal fitting at the end of the anti-slip member is locked in the locking groove of the rotation operating rod, and the locking position of this locking groove is used as the fulcrum of the lever movement to set the rotation operating rod in the tightening direction of the connecting rope. The anti-slip member can be tightened and mounted on the outer circumferential surface of the tire by rotating the tire. Further, when the tightening amount is required, the hooking position of the turning operation rod on one end side of the connecting rope with respect to the hooking protrusion is changed, or the hook at the end of the non-slip member of the locking groove on the one end side is changed. By changing the locking position with respect to the metal fittings, that is, by changing the locking position that serves as the fulcrum of the lever movement of the rotating operation rod, the connecting rope can be retightened, and the non-slip member can be more firmly attached to the outer circumferential surface of the tire. The anti-slip device can be tightened and attached to the tire.

Moreover, the hooking protrusion has a protrusion height such that one end side of the connecting rope is not likely to come off, that is, a protruding height at which one end side of the connecting rope can be hooked in a state where the one end side of the connecting rope is completely immersed in the protruding height. Since it is formed, the connecting rope does not accidentally come off from the hooking protrusion during the tightening operation in the tightening direction by the rotating operation rod, and the connecting rope is pulled in the tightening direction to ensure Can be tightened to.

Therefore, according to the tightening device of the present invention, there is no fear that the connecting rope will come off from the latching protrusion during the tightening operation, and the lever principle is used to obtain a sufficient tightening force even by the force of a person. A certain tightening operation is possible, and moreover, the connecting rope can be retightened by changing the hooking position of the connecting rope with respect to the hooking protrusion, and the fulcrum of the lever of the rotating operation rod. Outer surface in the circumferential direction The anti-slip device can be firmly and firmly attached to the tire in a state of being firmly adhered to the so-called road surface installation surface, which is caused by the non-slip member being lifted from the outer surface in the circumferential direction of the tire as in the past. vibration,
It is possible to prevent noise and damage to the tire body, the slip stopper, and the vehicle body.
