PROBLEM TO BE SOLVED: To provide a snow removing labor saving device capable of saving labor of single elderly persons and physically handicapped persons required to remove snow from the roofs of their houses and preventing the occurrence of collapse of the houses and accidents of such persons falling down from the roofs and resulting in death while removing the snow from the roofs in a heavy snowfall area. SOLUTION: In this snow removing labor saving device, its shaft is formed by a pipe as much as possible, and this device is driven by one pipe. Its frame structure is formed by pipes, an upper part of its inside rotates in idling, a lower part of its inside is driven, and a chain is fixed by welding. A pipe impeller is driven by a biaxial motor in two pairs of frames to prevent swing and prevent a wire from being broken. Right and left sides or either of them of a motor side frame must be curved and extended to supplement projecting parts other than the rectangular roof so that an extending and contracting part with a wire becomes necessary depending on roof structure. The motor is rotated back and forth by a limit switch in an end part of the pipe frame. COPYRIGHT: (C)2009,JPO&INPIT
