<P>PROBLEM TO BE SOLVED: To facilitate manufacturing and working, and to easily conduct inspection before use for maintaining a plugging function. <P>SOLUTION: A plugging plug 20 for a heat-conducting pipe, which is used to plug the heat-conducing pipe and thus block off the heat-conducting pipe, is equipped with: a plug body 21, which is formed so as to be capable of being inserted into the heat-conducting pipe, and is formed with a closed cylindrical end and other open cylindrical end; a column component 22, which is capable of being inserted into and removed from the plug body 21 from the cylindrical open end of the plug body 21, and has at its outer perimeter a tapered surface 22a the outer diameter of which decreases gradually in the direction of the open end side of the plug body 21 while the column component is inserted into the plug body 21; and a wedge member 23, which is formed so as to be capable of being inserted into and removed from the plug body 21 from the cylindrical open end side of the plug body 21, and has at its inner perimeter a tapered surface 23a, the inner diameter of which gradually decreases in the direction of the open end side of the plug body 21 and which opposes the tapered surface 22a of the column component 22 while the wedge member is inserted into the plug body 21. <P>COPYRIGHT: (C)2013,JPO&INPIT |
