Abstract: <P>PROBLEM TO BE SOLVED: To provide a sealed tubular body whose insertion hole has excellent sealability without subjecting a sealing member to striking, and to provide a method for manufacturing a sealed tubular body.  <P>SOLUTION: The sealed tubular body comprises a tubular member 20 with a insertion hole 21 and a sealing member 30 positioned inside the insertion hole 21. A tube expansion punch is struck and pressed to a protruding part 25 protruding from the inner-wall surface of the insertion hole 21. Thereby, a tube expanded part where the outer diameter of the insertion hole 21 in which the tube expansion punch is inserted is formed. Further, a receiving part 27 having steps is formed at a strike stop region of the tube expansion punch by inserting a tube expansion punch of a prescribed shape. The diameter of the tube expanded part is reduced, by inserting the expanded part into a reduced-diameter working hole whose inner diameter is smaller than the outer diameter of the expanded part after making the receiving part 27 to receive the sealing member 30. By the diameter-reducing, the outer circumferential edge part of the sealing member 30 bites into the inner wall surface of the insertion hole 21.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
