<p>PROBLEM TO BE SOLVED: To permit stable fixing, even when no tension is being applied to a cable, and to easily perform fitting, performing adjustment to the angle of curvature or direction of drawing of the cable, in a guide roller when the cable led out from the end part of a pipe is curved and inserted into another pipe and so on, at a manhole, a junction site of another conduit line, and so on. SOLUTION: A guide roller 1 has a plurality of freely-rotatable rollers 3 arranged between two frames 2, 2, which curve and along the frames 2. and each one end of these frames 2 is fittable to the pipe mouth of an embedded pipe 14 freely attachably and detachably. This guide roller 1 is divided into a tip section 1b and a base section 1a to be fixed to the pipe mouth of the embedded pipe 14, and these base section 1a and tip sections 1b are mutually freely connectable. In addition, it is possible to make a trip section 1b front and back sides reversed and connectable to a base section 1a so as to be s- shaped. Moreover, the tip section 1b is constituted to be extendable from the base section 1a in this reverse connection.</p> |
