  • Sealant for prevention of blowout, tubeless tire, and tire tube
    Patent number: 7316253
    Abstract: The viscosity of a puncture-preventing sealant (7) is set in a range of 25 to 35 dPa·s, and a thixotropy index is set in a range of 6.5 to 11.0, the sealant (7) being filled in a sealant chamber (6) defined to extend along an outer periphery of an air chamber (5) in a tire (T). When the tire (T) is being rotated by traveling of a vehicle, the viscosity of the sealant (7) is reduced by a stirring action provided by a vibration or a centrifugal force of the sealant (7), whereby the sealant (7) can be diffused uniformly in the sealant chamber (6). When the vehicle has been stopped and the stirring action has been extinguished, the viscosity of the sealant (7) is increased, whereby the sealant (7) is maintained in a state in which it has been diffused uniformly in the sealant chamber (6) without flowing downwards in the sealant chamber (6) by gravitation. Therefore, even when the vehicle is travelling at a high speed, the generation of a vibration and a noise can be prevented.

  • Compound sheet gasket
    Patent number: 7048278
    Abstract: A compound sheet gasket which exhibits superior sealing durability to fretting is provided. The compound sheet gasket is mounted between a housing and a cover provided at an opening of the housing, and the friction coefficient of any one surface of a front surface adhered to the housing by the flexibility thereof and a rear surface adhered to the cover by the flexibility thereof, is set to be 1.15 times or more that of the other.
