<P>PROBLEM TO BE SOLVED: To provide a live-line distributing tool for securely whirl-stopping a cylindrical section and a contraction cylinder, which mutually slide, and contract and slide in an axial direction by rotation of a screw shaft receiving a rotary operation from outside for distributing a live-line, with the small number of components and less assembly man-hour. <P>SOLUTION: In whirl stop means 5 of a cylindrical section 1 and a contraction cylinder 2, which mutually slide and contract and slide in the axial direction by the rotation of a screw shaft 4 receiving the rotary operation from outside, a plane section 51 in a state where a circular face of an outer periphery of a nut 3 installed on the contraction cylinder 2 is shaved off to convert the rotation of the screw shaft 4 into the slide of the contraction cylinder 2, and a plane section 52 which is in a padding state from the circular face of an inner periphery of the cylindrical section 1 to an inner diameter side so that it mutually slides with the plane section 51 in a contraction/slide direction are arranged at least in one place in a circumferential direction, and the plane sections are made into a pair of planes integrating the contraction cylinder 2 and the cylindrical section 1 in the circumferential direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
