PROBLEM TO BE SOLVED: To provide an electric elevating window device for greatly reducing a serial construction time at a site by applying serial construction to a plurality of window units while easily and efficiently arranging and positioning the mutual window units. SOLUTION: The electric elevating window device comprises a pair of guide rails 1, an elevated window 3 to be elevated up and down between the guide rails 1, and a winder unit 7 arranged above both guide rails 1 for driving the elevated window 3 to be elevated. The winder unit 7 is stored in an outer size space between both guide rails 1 to form the window unit U1 with the guide rail 1 and the winder unit 7 integrated. To serially mount the plurality of window units U1, the guide rail 1 for each window unit U1 has positioning portions 1b, 1c, 1d on the outside face for positioning the guide rails 1 in the adjacent state in a predetermined direction.
