<P>PROBLEM TO BE SOLVED: To mount a cylindrical flexible membrane onto an insertion part, a cylinder for its mounting or the like without being substantially slid only by expanding fastening parts at both ends of a balloon to be retained on outer and inner cylinders. <P>SOLUTION: The balloon mounting device is constituted of the outer cylinder 20 comprising a cylindrical member and the inner cylinder 21 which is disposed in the outer cylinder 20 and has an inner cylinder part 24 and a piston part 25 successively installed at the base end part of the inner cylinder part 24. The first holding part 34 on which is retained one ring-like fastening part 11a of the balloon 10 is provided on the outer surface of the tip of the outer cylinder 20 and the second holding part 35 on which is retained the other ring-like fastening part 11b is provided on the tip of the outer surface of the inner cylinder 21. The inner cylinder 21 has a moving stroke from a position protruding by a prescribed length from the outer cylinder 20 at which the insertion part 1 is inserted into an insertion part receptacle part 28 formed in the inner cylinder part 24 of the inner cylinder 21 to a position at which a fastening groove 3b on its base end side almost faces the first holding part 34. <P>COPYRIGHT: (C)2007,JPO&INPIT |
