PROBLEM TO BE SOLVED: To provide a sealing pumping-up device capable of suppressing the leak amount of a sealant during repairing. SOLUTION: First, the compressed air formed by a compressor is supplied to a pneumatic tire 32 through piping 14, a branch part 16, piping 20, a changeover valve 28 and a joint hose 30. When the pneumatic tire 32 becomes the set pressure P<SB>1</SB>of internal pressure P≥releaf valve 22, the releaf valve 22 is operated, the compressed air is supplied into a solvent container 26 through the releaf valve 22, the sealant of the liquid container 26 is pushed to the changeover valve 28 by inflow air, a flow is changed over in the changeover valve 28 and the sealant is supplied into a tire through the changeover valve 28 and a joint hose 30. Since the liquid container 26 is filled with the sealant after the filling with air, the time from the filling with the sealant to preparatory running is shortened and the leak amount of the sealant from a puncture hole is reduced.
