The present invention relates to a cleaner for both sides of window glass. In particular, the cleaner for both sides of window glass of the present invention comprises: rotational shafts composed of an outer rotational shaft part and an inner rotational shaft, the outer rotational shaft including a through hole formed therein in the longitudinal direction and upper shaft portions on one side and on the other side positioned respectively on the front and rear sides of a window, the inner rotational shaft part being inserted into the through hole of the outer rotational shaft and including lower shaft portions on one side and on the other side positioned respectively on the front and rear sides of the window; a fixing member axially coupled to the outer rotational shaft part of the rotational shafts and fixed to the other side of the window; a link member composed of a plurality of foldable links on one side and on the other side axially coupled to the upper shaft portions on one side and on the other side and to the lower shaft portions on one side and on the other side in a vertically foldable manner when positioned respectively on the front and rear sides of the window, upper links on one side and on the other side positioned respectively on the front and rear sides of the window by having the other end axially coupled to an upper side of the foldable links on one side and on the other side, and lower links on one side and on the other side positioned respectively on the front and rear sides of the window by being axially coupled to a lower side of the foldable links on the one side and on the other side; and a cleaning member having the other end axially coupled to one end of the upper links on one side and on the other side and to one end of the lower links on one side and on the other side, to thus move horizontally as the link member is being folded and open vertically for cleaning the front and rear surfaces of the window, while being in contact with the front and rear surfaces of the window respectively. With the cleaning member for cleaning both the front and rear surfaces of the window while moving horizontally as the link member is folded and open vertically, the present invention with such configuration makes it possible for a worker to clean the front and rear surfaces of the window more easily from the inside of a building without necessarily putting part of his body outside of the building for cleaning the rear surface of the window that is exposed to the outside of the building, and to thereby help prevent falling accidents in advance. |
