PROBLEM TO BE SOLVED: To obtain an opening/closing device or a sheet glass, which does not require a large number of parts and provides a simple constitution and also which is small, light and low in cost and further, high in the transmission efficiency of the driving power. SOLUTION: A plurality of flexible driving rods 18 are provided to be oppositely arranged to the worm gear integrally formed with the rotary shaft of a motor 10. A gear to mesh with the worm gear is fixed to the driving rods 18 to slide a plurality of driving rods 18 by the rotation of the worm gear. The engaging motion of the worm and the driving rods 18 are guided by a plurality of guide members 16 to retain the condition. The driving rods 18 are guided from the position of respective guide members 1 6 to the connection position of the windglass by the outer case 20 The ends of these driving rods 18 are connected to the windglass to provide the opening/closing drive force at a plurality of positions. |
