PROBLEM TO BE SOLVED: To enable the same tire to be easily attached and detached and have a slip prevention function which meets statutory requirements of our country.SOLUTION: A tire slip prevention mechanism includes: a wheel 3 which includes a wheel disc 3a attached to a vehicle body B and holds a tire 2; at least one blade 10 including a spike base 11 disposed in the tire 2, a spike pin 12 fixed onto the spike base 11, and arms 14, 114, 214 which extend from the spike base 11 to the radial inner side of the tire 2 along an outer surface of the tire 2 within a vehicle width W of the vehicle body B, the blade 10 disposed in the tire 2; holders 20 provided at the wheel disc 3a for each blade 10 and serving as holding means which detachably hold the blades 10 on the wheel disc 3a; and coil springs 30 disposed between the blade 10 and the holder 20 and serving as damper members. Each holder 20 detachably holds the blade 10 through the coil spring 30.SELECTED DRAWING: Figure 1

    【課題】着脱が容易であり、しかも我が国の法定要件を充足する滑止機能を同一タイヤに担わせること。【解決手段】車体Bに装着されるホイールディスク3aを含み、タイヤ2を担持するホイール3と、タイヤ2に配置されるスパイクベース11と、スパイクベース11上に固定されるスパイクピン12と、スパイクベース11から車体Bの車幅W内で当該タイヤ2の外側面に沿ってタイヤ2の径方向内方に延びるアーム14、114、214と、を含み、当該タイヤ2に少なくとも1個配置されるブレード10と、ブレード10ごとにホイールディスク3aに設けられ、かつ当該ブレード10を着脱可能にホイールディスク3aに保持する保持手段としてのホルダ20と、ブレード10とホルダ20との間に介装されるダンパ部材としてのコイルばね30と、を備えている。ホルダ20は、コイルばね30を介してブレード10を着脱可能に保持している。【選択図】図1
