Zusammenfassung:	PURPOSE:To insert guiding bodies by just pushing them in by fixing guiding bodies planted with elastic wires on their outer peripheries at the tip section of a wire guiding tool for an underground conduit having less bending rigidity toward the tip section from the base section. CONSTITUTION:An intra-tube wire guiding tool has a spiral flexible tube 2 consisting of respective flexible portions 5-8 and the first and second guiding members 3, 4 fixed at the tip section 2b and the middle section so that its bending rigidity is gradually decreased toward the tip section 2b from the base section 2a. Both guiding members 3, 4 are constituted with spherical guiding bodies 13 made of synthetic resin or the like and elastic wire trains 11, 12 planted on their outer peripheries 10a, 13a and are held in the axial center of a buried tube 9. Accordingly, the guiding bodies 3, 4 can be entered into the pipe 9 by just pushing the flexible tube 2 in without twisting it, thus a fiber scope 15 or a liquid injecting pipe to be held inside can be prevented from being damaged by twisting.
