Summary:PROBLEM TO BE SOLVED: To prevent snow from remaining in a snow trap without using a thawer, and enable the long spells of operation of the thawer, by equipping a snowfall device with a snow trap where plural pieces of line materials are stretched in parallel, and a snow shaker which shakes down the snow by touching and vibrating the plural pieces of line materials. SOLUTION: Cold air is taken in a snowfall device 1 by fan 2, and fine waterdrops 4 atomized by two-fluid nozzle 3 are frozen into ice particles by cold air, and these ice particles are trapped in a snow trap 5. At the point of time when the trapped ice particles have grown to not much larger snow, the snow shaker 6 shakes down the snow 7 in the snow trap 5 to accumulate it on a slope or the like. The snow trap 5 consists of a snow trapping frame 9 and an electrode frame 10 laid thereupon, and plural pieces of line materials 11 are stretched in parallel on the snow trapping frame 9. Moreover, the snow shaker 6 is equipped with a finger 13 for touching the line material 11 of the snow trap 5, supported by a mover 14.
