Tire puncture repair kit

A puncture repair kit comprising:

• a compressor device, and
• a bottle unit comprising a bottle container containing a puncture repair liquid, and an extraction cap fitted to a mouth portion of the bottle container, wherein the extraction cap has an intake port portion for feeding compressed air from the compressor device into the bottle container, and an outlet port portion for taking out the puncture repair liquid and the compressed air in succession from the bottle container by the feeding of the compressed air, and
• wherein the compressor device comprises
• a compressor main body having a cylinder having a main cylinder part forming a pump chamber for compressing the air, and a sub-cylinder part forming a surge chamber being contiguous to the main cylinder part and receiving the compressed air from the pump chamber, and
• a pressure gauge for measuring the pressure of the compressed air in the surge chamber, the pressure gauge comprising
• a tubular body portion which is provided in a front end portion with a communicating hole communicating with the surge chamber, and in which a cap is attached to a rear end portion,
• a piston having a seal ring sealing between the piston and the inner peripheral surface of the tubular body portion, and being movable together with the seal ring within the tubular body portion in the longitudinal direction by the compressed air from the communicating hole,
• a spring disposed between the piston and the cap so as to bias the piston toward the front end portion, and changing displacement of the spring by the magnitude of the pressure of the compressed air,
• an indicator portion disposed on a peripheral wall of the tubular body portion and indicating the amount of movement of the piston, wherein at least a part of the tubular body portion where the indicator portion is formed is transparent, and the seal ring is a pointer of the indicator portion and visible through the transparent part to indicate the moved position of the piston, and
• an exhaust port formed on the peripheral wall of the tubular body portion,
• wherein, when the compressed air reaches to a prescribed pressure and the seal ring moves beyond the exhaust port, the exhaust port communicates with the communicating hole, and exhausts the compressed air.
