摘要： To be able to simply carry out an operation of repairing a punctured pneumatic tire, to be able to inject a necessary amount of a sealing agent firmly into the pneumatic tire even when the apparatus is used in an inclined state and to prevent clogging of the sealing agent and leakage of a liquid by being pressurized.
A pump up apparatus 30 is an apparatus for injecting a sealing agent in a liquid state into a punctured pneumatic tire 38, thereafter, supplying compressed air into the pneumatic tire 38 to elevate an inner pressure thereof. The pump up apparatus 30 includes a sealing agent vessel 34 accommodating the sealing agent, a sealing agent injecting pump 42 for sucking the sealing agent from the sealing agent vessel 34 to feed it to the pneumatic tire 38, and a compressor 44 for pressurizing and sending air to the pneumatic tire 38. When the pneumatic tire 38 is punctured, the sealing agent injecting pump 42 sucks the sealing agent in the liquid state from the sealing agent vessel 34 to inject it to the pneumatic tire 38, therefore, inside of the sealing agent vessel 34 is not pressurized.
