However, in the conventional device as described above, in order to connect the runner to the moving body, a part of the runner is caulked, the caulked part is engaged with the belt, or the screw is used. Or, it is a general technique to sandwich a part of the moving body with a sandwiching plate, but the number of parts is large, and the work of connecting the belt and runner is troublesome. To open and close the
It is necessary to perform an adjustment work to apply a predetermined tension so that the moving body does not loosen in the rail, but after the moving body is assembled in the rail, the adjustment work is troublesome and adjustment is easy. There are problems such as not being able to do so.

In view of the above-mentioned conventional problems, the present invention provides an opening / closing device for an opening / closing body, which can adjust the tension of the belt and connect the runner and the belt easily and reliably. With the goal.

[0005]

In order to achieve the above-mentioned object, the device of the present invention comprises a rail having a generally downward U-shaped cross-section opening downward, and a motor pivotally attached to one end in the longitudinal direction of the rail. Drive pulley that is connected to the output shaft of the motor and rotates, and an adjustment plate that is movably supported at the other end of the rail in the rail longitudinal direction and that can be positionally adjusted in the rail longitudinal direction by a screw member whose axial direction faces the rail longitudinal direction. A driven pulley that is pivotally attached to the adjusting plate, and a loop that is formed on one side surface with uneven portions and that is looped between the drive pulley and the driven pulley and that moves along the longitudinal direction of the rail when the drive pulley rotates. -Shaped belt, slidably supported in the rail, connected with an opening / closing member, and has a connecting portion having an engaging portion that engages with the uneven portion of the belt. Engagement part In a state of being, by fitting the connecting portion connecting portion and the belt from the direction along the surrounding member which surrounds the belt moving direction, it is characterized by comprising a top runner coupled to the belt.

[0006]

[Operation] Fit the belt to the top runner connecting part,
By engaging the concavo-convex portion of the belt with the engaging portion, and then fitting the surrounding member to the connecting portion along the moving direction of the belt, and engaging the belt with the connecting portion of the top runner, the top runner is The belt is easily and reliably coupled to the belt without dislodging in the moving direction or the vertical direction.

The curtain can be opened and closed by rotating the drive pulley clockwise to circulate the belt.
