Thus, in the state shown in FIG. 7, the substrate
The mounting is completed by abutting the peripheral edge portion 101 of the peripheral portion 100 on the outer periphery of the mounting hole h of the top plate 12U and screwing a screw S or a nail into the hole 102 formed in the peripheral edge of the substrate.

The other end of the connecting shaft 24 extends to the upper surface of the top plate 12U and is rotatably supported by the bearing 26 fixed to the top plate 12U as described above and as shown in FIG. The other end of the connecting shaft 24 is connected to the rotating shaft 210 of the sprocket wheel 200 of the hanging endless chain type rotational force imparting device according to the present invention. Each tooth of the gears 21U and 21L is set to a size that meshes with a recess of the connecting portion 17c of the vertical slat 17 of the shutter. The bearings 23U and 23L also function as stoppers that stop the terminal slat 17e when the horizontal pull shutter ST is moved to the open position.

And, the window with the shutter opening / closing device, which is formed by connecting and connecting the transmission unit B, pulls down one predetermined side of the hanging portion of the endless chain 300, and thereby the connecting shaft 24, the conversion mechanism 25, the drive shaft 22, and the operation. Gear 21U,
The shutter ST can be closed via 21L,
Further, by pulling down the other side of the hanging portion of the endless churn, the lateral pulling shutter ST can be similarly opened.

It should be noted that, in order to easily determine which side of the endless chain is pulled down to open or close the shutter, both ends of the chain insertion hole on the lower surface of the substrate are respectively separated. Affixing a seal or the like printed with the characters "open" and "closed" has an advantage that it is possible to prevent unreasonable force from being applied to the endless chain.

The horizontal pulling shutter can be held at any position of fully open, fully closed, and half open, and the hanging portion of the endless chain 300 can hold the hanging portion of the vertical frame 3 or 4 even in the displaced state.
It can be pulled to the side and locked to the hook F. Since the hook is attached to the vertical frame, the locked endless chain hangs along the vertical frame without hanging in the bay window space,
It does not spoil the appearance of the bay window. Also, if horizontal pull shutters are provided separately on the left and right sides, the endless chains are locked to the hooks on the left and right sides of the bay window,
It becomes an accessory and improves the appearance of the bay window. Also, since the hook is attached to the vertical frame, when a curtain is provided in the bay window, it usually moves along the rail provided along the shape of the bay window and is opened and closed. The endless chain is also prevented from obstructing the opening and closing of the curtain.
