た。 In recent years, the demand for wagon cars has increased significantly.
Most wagons are equipped with curtains on the rear window and both side windows. In that case, it would be very convenient if it were possible to open the curtains when backing up, or close the curtains to shade the cabin from the sun, from the driver's seat, in order to maintain visibility while driving. Therefore, a device has been developed in which a loop-shaped perforated belt is provided in the curtain rail, a curtain hanging tool is engaged with the belt, and the curtain hanging tool moves as the belt moves. However, this method had the disadvantage that even if the curtains were to be opened or closed by hand when the belt was not moving, the hanging tools would get caught on the belt and the curtains could not be opened or closed. Therefore, one way to manually open and close such curtains was to lift the curtain hanger and disengage it from the belt, but this was time-consuming and required skill to operate. The drawback was that it could not be opened and closed like regular manual curtains.

As shown in FIG. 7 and FIG. 7, a single straight spiral body 25 can also be used. In this case, the spiral body 25 in the rail 24 is rotated by a motor, and the worm wheel 29 engages with the spiral body 25 in the hanging tool.
A ring 30 for supporting the hook 2 is provided on the hanging tool, and a friction clutch is similarly configured by a spring 31. In addition, as shown in FIG.
The rotating friction plate 39a of the hanger 3' where the ring 40 is located and the fixed friction part 40a of the ring 40 should be fitted with spring properties, or a surface condition should be formed to increase the frictional resistance therebetween. For example, a friction clutch can be constructed without using a spring. Furthermore, when a spring is not used, as shown in FIGS. 9 and 10, the rotating friction plate 3 of the hanging tool
9' and the fixed friction plate 40' of the ring may be polygonal so that they engage at the corners, or as shown in FIG. An engagement protrusion may be provided on the fixed friction plate 40''.
