The present invention relates to a device for preventing snow from being laid on various kinds of cultivation facilities, stables, and mud huts in farming and fishing villages. A large amount of snow causes huge damage when a large amount of snow is laid on vinyl greenhouses or stables. The device for preventing snow from being laid includes a driving wheel unit composed of a circular driving wheel engaged with a driving gear connected to an output shaft of a driving motor and a guider rotating according to the rotation of the driving wheel a driven wheel unit composed of a driven guider which rotates according to the rotation of tracks connected to the driving wheel by a form of a caterpillar a wire track unit which continuously induces the rotation of snow-laying preventing rods by being joined to the upper parts of the snow-laying preventing rods simultaneously with rotating by a form of a caterpillar while being hung on between the guider of the driving wheel unit and the driven guider of the driven wheel unit the snow-laying preventing rods of which the upper parts are joined to the wire track unit and which apply impact on snow being laid on the top of a roof while moving according to the rotation of the wire track unit a distance controlling unit capable of optimally adjusts the distance between the driving wheel unit and the driven wheel unit and a fixing unit composed of a position setting unit which is formed on the lower side of the distance controlling unit and joined to a framework of the top of the roof. Therefore, the present invention prevents snow from being laid as the snow-laying preventing rods apply impact on snow laying on the top of the roof according the rotation of the tracks of the wire track unit in case it heavily snows, thereby preventing the collapse of stables and greenhouses caused by the weight of snow being laid.COPYRIGHT KIPO 2014본 발명은 농어촌의 각종 재배사, 축사, 움막 등지에 쌓이는 눈을 적체하지 못하도록 방지하는 눈 쌓임 방지장치에 관한 것이다.눈이 일시에 다량 축적될 경우 비닐하우스나 축사 등이 붕괴하
