<p>PURPOSE:To provide a spacer whereby the generation of galloping vibrations is prevented and development of cylindrical ice or snow accretion having a circular section is suppressed. CONSTITUTION:Eelementary conductors 16, 16 are grasped fixedly at an even number of positions of which are situated axially symmetric with respect to the frames 12 by conductor grasping parts 14, 14 provided on one side of the symmetry axis of the frames 12, and other elementary conductors 16, 16 are so grasped by conductor loosely grasping parts 20, 20 provided on the other side of the symmetry axis as to be freely rockable within a predetermined angular range. In each conductor loosely grasping part 20, a loosely clamping main body 22 having a double structure comprising an inner tubular member 26 for grasping the elementary conductor 16 and an outer tubular member 30 which is openable around a pivot axis parallel with the elementary conductor 16 and wherein the inner tubular member 26 is fixed. Further, in this loosely clamping main body 22, a gap part 32 and a slit which reaches the gap 32 and can move around the pivot axis are provided respectively. moreover, in a coupling member 24, a T-shaped protrusion 24a whose head part is inserted into the gap part 32 and whose neck part is passed through the slit is so provided that it can pivot. Thereby, the loosely clamping main body 22 is so mounted on the coupling part 24 that it can pivot.</p> |
