と、該滑止めピンを装着した車両用タイヤに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip pin for preventing a vehicle tire from slipping on a snowy road or a frozen road in winter, and a vehicle tire provided with the non-slip pin.

タイヤとして使用していた。2. Description of the Related Art Heretofore, for example, a large number of metal spike pins have been implanted into the tires of automobiles by driving them into the tire surface and used as anti-slip tires on snowy roads or frozen roads in snowy countries. .

属製スパイクピンの使用が規制されるようになった。[0003] However, those in which a metal spike pin is driven into a vehicle tire exhibit excellent braking ability even on an icy road, but this only cuts the road surface and causes dust pollution. The use of the metal spike pins has been regulated.

いものである。Accordingly, snow tires having a deeper groove for vehicle tires have been used. However, although braking ability can be expected on snowy roads, braking on frozen roads is more difficult than with the metal spike pins. Inferior ability is inevitable.

ものが知られている（特公平６−６２８３６号）。[0005] Under such circumstances, a vulcanized rubber composition which acts as a sharp nail similar to metal on ice and snow surfaces is formed as a rubber non-slip pin, which is mounted on a vehicle tire. There is known a motor that obtains the same braking capability as a metal spike pin and does not cut the road surface (Japanese Patent Publication No. 6-62836).

となし、車両用タイヤ２の孔３に装着する。[0006] The vulcanized rubber composition is obtained by plasticizing polynorbornene with an aromatic oil, and adding a metal oxide fine particle to an improved polymer having a secondary transition point adjusted to a range of 0 ° C ± 5 ° C.
It is blended at a ratio of 50 parts or more to 100 parts of polynorbornene. This vulcanized rubber composition is shown in FIG.
As shown in FIG.
Then, it is mounted in the hole 3 of the vehicle tire 2.

軟に変形して路面５を削ることがない。As shown in FIGS. 6 (a) to 6 (c), the vehicle tire 2 equipped with the rubber anti-slip pins 10 is usually made of rubber on the road surface 5 (FIG. 6 (a)). The non-slip pin 10 has a low hardness and is flexibly deformed due to the characteristics of rubber, so that the road surface 5 is not shaved, and the anti-slip pin 10 on the icy and snowy road surface 6 (FIG. The tip portion responds and the hardness (Hs, JIS-A) hardens to about 84 °, and the tip portion protrudes from the tire surface and cuts into the ice and snow road surface 6 to exhibit the same braking ability as a metal spike pin. When the outside temperature is below the freezing point and there is no ice or snow (FIG. 6 (c)), the internal heat of the tire is conducted to the rubber non-slip pin 10 and the rubber non-slip pin 10 is flexibly deformed without hardening. And the road surface 5 is not cut.

有している。However, the rubber non-slip pin 10 has a sudden increase in hardness value on an icy and snowy road surface 6 and becomes hard and exerts a braking ability. On a normal road surface 5, it is soft and soft. However, the tip of the non-slip pin 10 is scraped off early due to contact and friction with the road surface 5, and the non-slip pin 10 is removed from the tire surface on the ice and snow road surface 6. There is a possibility that the tip of the protruding part 10 does not protrude and the braking ability is reduced. As described above, the conventional rubber non-slip pin has a problem to be solved in abrasion resistance.
