<p><P>PROBLEM TO BE SOLVED: To securely plug the inside of a pipe without requiring time and labor in mounting work even if another pipe is provided in close proximity on an outer peripheral side of a pipe end part. <P>SOLUTION: This plugging device in the pipe is provided with an elastic plugging member 1 plugging the inside of the pipe by compression deformation operation from the direction of a pipe shaft center, a pair of pressing members 2 pressing the elastic plugging member from the front and rear in the direction of pipe shaft center, a fixing part 3 fixing a pressing member 2a on one side to a pipe end part, and an operation part 4 moving a pressing member 2b on the other side toward a pressing member side on one side to compress, deform, and operate the elastic plugging member. The fixing part is constituted in such a way that a plurality of pressure-contact pins 9 provided with a pressure-contact face 9a coming into pressure-contact with an inner face of the pipe on a tip side are held on the pressing member on one side radially across substantially equal interval in the peripheral direction of the pipe so as to come out and retract freely in the direction of pipe diameter and a cylindrical movable member 11 provided with a tapered face 13 capable of pushing out these contact-pressure pins to an outward side in the direction of pipe diameter by pushing-in operation from the direction of pipe shaft center to a terminal side of the pressure-contact pin is provided so as to perform pushing-in operation freely. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
