Abstract
PURPOSE:To reduce noise or damaged due to vibration considerably, by applying critical condition to a gap between a wire and a spiral rod. CONSTITUTION:A spiral rod 2 has an inner diameter longer than the outer diameter D of a wire 1 so as to form a gap (delta) between them. Consequently, snow adhered to the wire 1 can be removed by moving the spiral rod 2 on the outer circumference of the wire 1. A critical point for causing vibration exists at a point where delta/D=0.2. When the gap (delta) is selected to satisfy a condition 0<delta/D=0.2, vibration and accompanying trouble can be prevented sufficiently, and noise or damage of wire can be reduced considerably even if the spiral rod 2 is mounted movably.
