Document Type and Number:
Japanese Patent JP2763811
Kind Code:
B2
Abstract:
PURPOSE:To improve durability by setting a slippage-preventive pin through engagement of plural uneven stripes extending in the axial direction in a cylinder buried inside a tire, and energizing it with a spring, and preventing slip-out with engagement between the slip-out preventing part of a slippage-preventive pin rear end and the inner stage part of a cylinder. CONSTITUTION:Slippage-preventive pin units 10, which are respectively buried in many holes 15 being bored in proper positions at the whole circumference of the tred part 11d of a tire 11, are constituted by setting slippage-preventive pins 32 in cylindrical cylinders 12 where flange parts 14 are formed integrally at the ends. In this case, at the slippage preventive pins 32, uneven stripes 33 extending in the axial direction are formed at several places (three places) of the periphery and also a hard chip 24 is fixed to the end. While, at the cylinder 12, a diameter reduced cylinder part 12A, where uneven stripes 13 almost in accordance with the shapes of the uneven stripes 33 of the slippage-preventive pin 32 are provided at the inner face, is formed on the top side of the inwall, and a step part 16, Where the slip-out preventing part 20 of the slippage-preventive pin 32 engages, is formed at the boundary part between the said part 12A and the diameter-expanded cylinder part 12B on the rear end side of the cylinder 12.
