<P>PROBLEM TO BE SOLVED: To provide a snow-resistant ring capable of adjusting an inner diameter according to variation in the diameter of a power transmission line, and capable of surely gripping the power transmission line. <P>SOLUTION: A snow-resistant ring is made of a spiral body 2 having spring elasticity which is formed to be a length of almost one cycle of a spiral, and at both ends of the spiral body 2, slide engagement parts 3A and 3B which diagonally slide and engage with both side edges are formed. The spiral body 2 becomes a ring-shape when both ends are slid-engaged. By holding the engagement state of both ends at different positions in sliding direction, the inner diameter of the ring can be adjusted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
