<P>PROBLEM TO BE SOLVED: To provide a motor-driven elevating window device, finely adjusting a pair of chains with a length shorter than the length of one piece to easily prevent uneven slant lowering of an elevating window while the elevating window is suspended by the paired right and left chains independent from each other. <P>SOLUTION: This motor-driven window device includes: a pair of guide rails 1; a pair of sprockets 10 synchronously driven to rotate by a switch 8 of a window elevating driving system; right and left window suspending chains 11 engaged with the sprockets 10 to be suspended in the guide rails 1; an elevating window 3 suspended by the window suspending chains 11 to be elevated between both guide rails 1; the lowermost chain piece 15A removably connected to the suspended lower end part of the window suspending chain 11; and a chain connecting plate 17 fitted to both sides of the upper part of the elevating window 3, wherein the device further includes a chain connecting means for selectively connecting the chain connecting plate 17 and the lowermost chain piece 15A to the height direction of the chain connecting plate 17 at every pitch shorter than the link pin pitch of the window suspending chain 11. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
