PROBLEM TO BE SOLVED: To provide a sealing pumping up device improving separation performance of a cap member when pressed by pressurized air. SOLUTION: The sealing device 10 includes: an injection unit 30 having an insertion part to which an opening 22 of a container 20 is inserted, a gas sending-in port 54A for sending pressurized air to inside of the container 20 and a gas liquid sending-out port 46A sending out a sealing agent 16 and pressurized air to a pneumatic tire 14; the cap member 70 having an engagement projection 76 fitted to an engagement recess 43 of the injection unit 30 and covering and closing the gas sending-in port 54A and the gas liquid sending-out port 46A; a release lever member 80 releasing the engagement state of the engagement recess 43 with the engagement projection 76 cooperated with the insertion operation of the container 20 when the opening 22 is inserted to the back side of the insertion part. This configuration improves separation performance of the cap member 70 when pressed by pressurized air. COPYRIGHT: (C)2011,JPO&INPIT
