Abstract
To prevent a burr, produced from the joint portion by welding between a liquid agent container and an injection unit, from interfering with a boring member inserted into a jig communication passage when the boring member is inserted into the jig communication passage to prevent the obstruction of the piercing action through a sealing member by the edge of the boring member. In the sealing pump-up device, a tubular inner annular memberis integrally formed on the inner peripheral side of a joined portionin an injection unitso as to surround, from an outer peripheral side, a boring memberheld in a jig insertion hole, and a burr housing unitconsisting of an almost cylindrical space is formed between the outer annular memberof a liquid containerand the tubular inner annular member, whereby it is possible to guide the tip end side of a burr, extending from the joint portion between the outer annular memberand a joined portiontoward the inner peripheral side, from moving toward the boring memberside of the burrby means of the tubular inner annular member
