開昭６４−６７４０６号）。FIG. 16 shows a different conventional example. The difference from the above conventional example is that the outer flexible cord 5 is a substantially non-stretchable rope, and the circumference can be adjusted. In order to adjust the circumference, one end of the flexible cord 5 is hooked to the hook 7 as a ring portion 8, and the other end of the flexible cord 5 is inserted into the ring portion 8 and then passed through the loosening stopper 9, It is hooked on the hook 7 via the hook 10. Thereby, the flexible cord 5 is attached to the main body 3
The main body 3 is tightened by changing the circumference in the tightening direction and locking it by friction with the locking device 9. Then, there is also one in which a tightening tool having a ratchet mechanism and a booster mechanism is attached to the rope so that the rope can be tightened with a small force (Japanese Patent Laid-Open No. 64-67406).

装着困難なものである。(Problems to be Solved by the Invention) If the outer flexible cord 5 is composed of a plurality of rubber cords, the main body 3
Takes time to engage. Further, in order to prevent the main body 3 from moving radially outward and colliding with the vehicle body due to the centrifugal force due to the rotation of the tire, it is necessary to increase the spring constant of the rubber cord, and therefore a large force is required for mounting. It is difficult for a weak person to wear.

するという問題がある。If the outer flexible cord 5 is a substantially non-stretchable rope, the main body 3 cannot be sufficiently tightened by a person pulling it by hand, and the main body 3 is loosened while the vehicle is traveling and needs to be tightened again. Becomes Therefore, it is conceivable to use the rope to which the above-described conventional fastening tool having a ratchet mechanism and a booster mechanism is attached, but the conventional fastening tool cannot be removed from the rope, and the fastening tool cannot be removed. Both ends of the rope are connected by themselves. Therefore, the centrifugal force for moving the main body 3 radially outward becomes large due to the weight of the fastener, and there is a problem that the main body 3 collides with the vehicle body.

本考案は上記従来の問題点を解決することを目的とす

る。(Means for Solving the Problem) A feature of the present invention is that a substantially mesh-shaped non-slip device body 3 is wound around an outer peripheral surface of a tire 2, and a tire inner end of the non-slip device body 3 is tightened. The flexible cord 4 is engaged in a ring shape, the end flexible cord 5 for tightening is engaged in an annular shape with the tire outer end of the anti-slip body 3, and the flexible cord 5 is closed. In a mounting structure of a tire anti-slip device that connects both ends of the holder, holders 11 and 12 are detachably attached to both ends of the endless flexible cord 5, and one holder 11 is the other holder. A rack 3 which is inserted into the cord 12 so that it can be freely inserted and removed in the tightening direction.
4, the other holding body 12 has a ratchet wheel 35 that can mesh with the rack 34, a lever 38 that rotates the ratchet wheel 35, and a claw 40 that can regulate the return rotation of the ratchet wheel 35. In point.

The first holding member 11 is rotated in the opposite direction to the rope 5
The attachment of the anti-skid device 1 is completed by removing it from a, rotating the pressing piece 28 in the direction opposite to the arrow B direction, and removing the second holding body 12 from the rope 5b. In addition, by providing the rubber body 50, it is possible to prevent the main body 3 from getting loose with the tire 2 while running or growing and growing.

る。FIG. 5 and FIG. 6 relate to different embodiments. The difference from the first embodiment is that the entire flexible cord 5 is a substantially non-stretchable rope. The hook 7 to be engaged is attached to the main body 3 via a rubber body 50 having a larger elasticity than the main body 3. That is, the rubber body 50 is fixed to the main body 3, and the hook 7 is inserted into the through hole 51 formed in the rubber body 50. As a result, even if the flexible cord 5 itself is non-stretchable, as shown in FIGS. 7 and 8, the hook 7 is directly attached to the less elastic body 3 in which the core material 53 is embedded.
It is possible to prevent the main body 3 from running in conformity with the tire 2 and loosening due to elongation due to growth, as compared with those in which the vehicle is mounted.

The difference from the first embodiment is that the entire flexible cord 5 is a substantially non-stretchable rope, and the hook for engaging this flexible cord 5 is used. By using 7 itself as a spring, the same effect as that of the embodiment shown in FIGS. 5 and 6 can be obtained. The shape of the hook 7 used as a spring may be as shown in each of FIGS. 10 to 12.

遠心力を大きくする。Further, FIG. 13 relates to a comparative example, and is different from the conventional example shown in FIG. 16 in that the flexible cord 5 is formed of a rope 5a, a rope 5b and an elastic body 5c, and the rope 5a and the rope 5b are different from each other. Each end is connected via an elastic body 5c, the other end of the rope 5a is looped and hooked on the hook 7, and the other end of the rope 5b is connected to the moving pulley 5
After being wound around 5, it is inserted into the loosening stopper 9 and hooked on the hook 7 via the hook 10, and its moving pulley 55 is hooked on the hook 7 via the hook 56. As a result, when the flexible cord 5 is tightened by a person's hand, the force required for the tightening can be reduced by the action of the moving pulley 55, and the elastic body 5c acts to fit the tire 2 of the main body 3 during traveling. Therefore, it is possible to prevent loosening due to growth due to growth. However, the weight of the movable pulley 55 increases the centrifugal force that moves the main body 3 in the radial direction as compared with the present application.

1 and 12 are detachably attached to one holding body 11
Has a rack 34 that can be inserted into and removed from the other holding body 12 in the tightening direction of the rope body 5, and the other holding body 12 has the rack 34.
Since it has the ratchet wheel 35 that can be engaged with 4, the lever 38 that rotates the ratchet wheel 35, and the claw 40 that can regulate the return rotation of the ratchet wheel 35, both ends of the endless flexible cord 5 are provided. On the holder 11,1
2 is attached, the rack 34 of one holding body 11 is inserted into the other holding body 12, and is engaged with the ratchet wheel 35.
By rotating the lever 38 with the lever 38, one holding body 11 can be drawn to the other holding body 12 via the rack 34 to move both ends of the endless flexible cord 5 in the tightening direction.
Since the flexible cord 5 can be easily attached with a small force and both the holding bodies 11 and 12 can be removed from the flexible cord, the centrifugal force for moving the main body radially outward is small. Therefore, it is possible to prevent the main body from colliding with the vehicle body.
