PROBLEM TO BE SOLVED: To easily and quickly inject a suitable amount of tire-life extending agent by providing a feed machine for feeding out the tire-life extending agent in a tank, and an operating machine for injecting the tire-life extending agent into a tire. SOLUTION: A tire-life extending agent in a tank 2 is passed through a suction hose 8 to be introduced into a gear pump in a feed machine 3. The tire-life extending agent sent out from the pump is introduced into an operating machine 4 through a feed hose 7. Then, the tire-life extending agent passes through an injector connected to the tip of the operating machine 4 and is then injected from a tire valve into a tire. An injection device 1 uses a battery 6 as a driving power source, and is excellent in its portability, since there is no need for laying a power cable. A battery charger 5 and the battery 6 can be stored in a rack. Thus, a suitable amount of the tire-life extending agent can be easily and quickly injected. |
