PROBLEM TO BE SOLVED: To solve the problem that it needs tremendous labor, time and expense mostly for pipework etc. with no extractor to extract a broken or snapped part at a screw or the neck of a set-in part. SOLUTION: This tool is constituted such that: an object incorporated with a main body 1, a taper rod 2 and a nut 3 is inserted in a broken object a that is broken and left in tubing b; the incorporated object bites in the broken object a and is integrated therewith since a slit of the main body 1 is expanded by the taper rod 2 by turning the nut 3; and the main body 1 is turned by a spanner or the like. By this, the broken object can be easily taken out, and the labor, time and expense can be reduced. COPYRIGHT: (C)2005,JPO&NCIPI
