PURPOSE: To install an automatic opening-closing device for a window capable of being mounted or dismounted onto or from an existing window at low cost by a method wherein a pair of bearers capable of being simply fixed onto the window by suckers are mounted on an opening-closing guide, a sensor, a control means and an electric motor are set up to one of the bearers, the opening-closing guide is driven, and both bearers are opened and closed. CONSTITUTION: A pair of bearers 3a, 3b are mounted on an opening-closing guide 2, to which a rack gear 1 extending over the opening-closing stroke of a window is installed. The bearer 3a is fixed onto a part of the opening-closing guide 2, while a bearer-driving means 16 forwardly moving the opening-closing guide 2 is set up to another bearer 3b, and suckers 7 are fitted to both bearers 3a, 3b. The inside of the box body 18 of the bearer 3b is filled with a circuit board, on which a pinion gear 4, with which the rack gear 1 is engaged, an electric motor 5 for rotating the pinion gear 4, and a control means 6 for controlling the electric motor 5 are built. An input switch for setting a temperature and a display means 21 are attached onto the surface on the box body 18, and a sensor is connected to the circuit board through a connector. The opening-closing guide 2 is held by the pinion gear 4 and a press roller 23, and an auxiliary gear 24 is mounted on the side of the pinion gear 4 along the opening-closing guide. |
