  • Tire stem assembly
    Patent number: 5299614
    Abstract: The present invention concerns an improvement in securing a tire stem assembly. Specifically, a rubber packing piece, washer and securing nut-containing rubber packing piece are employed in this assembly, which cause the tire stem to bind tightly to the hub when the inner tube is inflated. The merit is that air cannot escape quickly from the space between the stem and the hub when the inner tube of a tire is punctured by a sharp object, thereby allowing the motor-driven vehicle to continue to operate.
