PURPOSE:To make an angle of each slat adjustable with the same phase, by pivoting both ends of a supporting body for flats fitted in a multistep way, on a vertical frame which is relatively moved up and down by means of a driving device, in case of a blind to be set to a rear window of automobiles. CONSTITUTION:In a state that each of slat 3 opens a blind in a horizontal position, when a control switch is operated to close a blind 1, rotation in a motor 17 is brought into a deceleration state 18 and transmitted to an output shaft 19. At this time, an engaging body 20 is forcibly pressed down to an adapter plate 15 by dint of a spring 26 via a pressing plate 25 and a clutch plate 24 so that the engaging body 20 and the adapter plate 15 both are rotated in the same direction due to rotation of the output shaft 19. If so, both 20 and 15 are turned round upward with a base end part of a supporting rod 22 as a fulcrum and with this, vertical frames 5a and 5b belonging to a supporting member 4 are relatively moved up and down, making the blind 1 come into a state of being closed. Afterward the transmission of turning force to the side of the adapter plate 15 of the output shaft 19 is cut by no-load running between the pressing plate 25 and the clutch plate 24. |
