PROBLEM TO BE SOLVED: To provide a blind driving device for double glazing with a blind capable of smoothly performing the rotary motion of magnets while maintaining transmission force of blind driving force. SOLUTION: The double glazing 10 with the blind is mainly provided with two panes of plate glass 11, 12, a spacer 14 fittingly inserted between the plate glass 11, 12 to specify an internal space layer 13, and the blind 15 disposed in the internal space layer 13. The blind 15 is operated by the blind driving device 100. The blind driving device 100 has a cylindrical magnet 31 mounted to one end of a support operating shaft 35 through a speed reducer 32, and a cylindrical magnet 40 connected to the rotational operating shaft 37 and disposed facing the cylindrical magnet 31. A distance between the cylindrical magnets 31, 40 is 6 mm. COPYRIGHT: (C)2005,JPO&NCIPI
