PURPOSE:To improve setting strength in a spike device as well as to prevent this spike device from jumping off, by attaching the spike device to a core material forming an antiskid device body and its covering material both, respectively. CONSTITUTION:An antiskid device 8 consists of an antiskid device body 9 and a lot of spike devices 10. And the antiskid device body 9 is provided with a central part 11 to be situated on top of a tire tread part and a side edge part 12 to be situated on top of both shoulder parts and both sidewall parts likewise. And, the antiskid device body 9 is formed in this way that the core material 13 formed reticulately is covered with a covering material 14. In this constitution, each of axial lug parts 15 and 16 is formed in the central part of the antiskid device body 9 and the side parts 12. And both ends of the spike device 10 are inserted into holes 22 formed at both sides of one side of the axial lug part 15. That is to say, these spike devices 10 are attached to the core material 13 and the covering material 14 in the antiskid device body 9 either. |
