FIG. 3 is a plan view schematically showing an example of the film member driving unit 30. In FIG. 3, a state in which the roof device 100 is open is shown as an example. Further, in FIG. 3, in order to make it easy to distinguish the configuration of each part, the first cable 21 is shown by a chain double-dashed line, and the second cable 22 is not shown.

As shown in FIG. 3, two leading carriages 33 are arranged for each set of first cables 21. Each leading carriage 33 may have a position sensor (not shown) that detects the position of the first direction D1. One of the two leading bogies 33, the leading bogie (hereinafter referred to as the first leading bogie) 33a, is arranged on the inner peripheral surface 103a side. Further, the other traveling carriage (hereinafter, referred to as a second leading carriage) 33b is arranged on the inner peripheral surface 103b side.

The first leading carriage 33a moves in the section of the first cable 21 from the inner peripheral surface 103a to the central portion of the opening 103. Of the film members 10 arranged on the inner peripheral surface 103a side, the end portion on the center side of the first direction D1 (hereinafter, referred to as the front end side end portion 11) is fixed to the first leading carriage 33a.

The first leading carriage 33a moves the leading end portion 11 of the film member 10 in the traveling direction by traveling in the first direction D1. For example, when the first leading carriage 33a moves from the inner peripheral surface 103a side to the center side of the opening 103, the leading end portion 11 of the film member 10 moves to the center side of the opening 103 according to the first leading carriage 33a. .. Therefore, the film member 10 extends and spreads in the first direction D1. Further, for example, when the first leading carriage 33a moves from the center side of the opening 103 to the inner peripheral surface 103a side, the leading end portion 11 of the film member 10 moves to the inner peripheral surface 103a side according to the first leading carriage 33a.

Of the film members 10 arranged on the inner peripheral surface 103b side, the end portion on the center side of the first direction D1 (hereinafter, referred to as the front end side end portion 12) is fixed to the second leading carriage 33b.

The second leading carriage 33b moves the leading end portion 12 of the film member 10 in the traveling direction by traveling in the first direction D1. For example, when the second leading carriage 33b moves from the inner peripheral surface 103b side to the center side of the opening 103, the leading end portion 12 of the film member 10 moves to the center side of the opening 103 according to the second leading carriage 33b. .. Therefore, the film member 10 extends and spreads in the first direction D1. Further, for example, when the second leading carriage 33b moves from the center side of the opening 103 to the inner peripheral surface 103b side, the leading end portion 12 of the film member 10 moves to the inner peripheral surface 103b side according to the second leading carriage 33b. To do. Therefore, the film member 10 is folded in the first direction D1 and contracts.

The first leading carriage 33a and the second leading carriage 33b are connected by one wire 35. The wire 35 is formed, for example, in an endless shape, and is bridged between a wire driving unit 36 arranged on the inner peripheral surface 103a side and a pulley 37 arranged on the inner peripheral surface 103b side. The wire drive unit 36 may be arranged on the inner peripheral surface 103b side, and the pulley 37 may be arranged on the inner peripheral surface 103a side.

The wire 35 is moved in the circumferential direction by the wire driving unit 36. As the wire 35 moves in the circumferential direction, the first leading carriage 33a and the second leading carriage 33b move in conjunction with each other. When one of the wires 35 is arranged at the center of the first direction D1 of the opening 103, the first leading carriage 33a and the second leading carriage 33b are in contact with the first direction D1 at the central portion. They are connected in a different positional relationship. In such a positional relationship, for example, in a state where the endless wire 35 is extended in one direction, the first leading carriage 33a is connected to one end and the second leading carriage 33b is connected to the other end. Is feasible. By connecting the wires 35 in this way, when the wire 35 is moved around, for example, the first leading carriage 33a and the second leading carriage 33b are brought into contact with the first direction D1 at the center of the first direction D1 of the opening 103. It can be in a state of being.

A plurality of intermediate carriages 34 are provided on the inner peripheral surface 103a side and the inner peripheral surface 103b side in one set of the first cables 21. The intermediate carriage 34 provided on the inner peripheral surface 103a side is arranged between the inner peripheral surface 103a and the first leading carriage 33a, and travels in the section between the inner peripheral surface 103a and the first leading carriage 33a. Further, the intermediate carriage 34 provided on the inner peripheral surface 103b side is arranged between the inner peripheral surface 103b and the second leading carriage 33b, and travels in the section between the inner peripheral surface 103b and the second leading carriage 33b. .. A part of the film member 10 is fixed to the intermediate carriage 34.

The number of intermediate carriages 34 is set for each first cable 21, for example, according to the length of the first cable 21 in the first direction D1. For example, in the first cable 21 arranged at the center of the second direction D2 and its vicinity thereof, since the length of the first direction D1 is relatively long, a large number of intermediate carriages 34 are arranged. On the other hand, in the first cable 21 arranged at the end of the second direction D2 and its vicinity, the length of the first direction D1 is relatively short, so that the number of intermediate carriages 34 is small.

The intermediate carriages 34 arranged on the different first cables 21 are connected by the ridge cable 38. The ridge cable 38 is stretched over both ends of the opening 103 in the second direction D2. A plurality of ridge cables 38 are arranged in the first direction D1. One intermediate carriage 34 arranged in each first cable 21 is connected by one ridge cable 38. A part of the film member 10 may be fixed to the ridge cable 38.

The ridge cable 38 is moved in the first direction D1 by the ridge cable drive unit 39, or the length of the portion stretched over the opening 103 is adjusted (hereinafter, these operations are combined to drive the ridge cable 38. It is possible to write "to do"). By driving the ridge cable 38, the ridge cable drive unit 39 moves each intermediate carriage 34 connected to the ridge cable 38 in the first direction D1. Therefore, by driving one ridge cable 38, it is possible to synchronize the intermediate carriages 34 arranged on the different first cables 21 and move them in the first direction D1.

FIG. 4 is a diagram showing a state in which the film member 10 is in the process of opening and closing. As shown in FIG. 4, for example, when the roof device 100 is closed, the wire driving unit 36 orbits the wire 35 so that the first leading carriage 33a is moved from the position on the inner peripheral surface 103a side to the center of the opening 103. Move to the side. Further, the second leading carriage 33b moves from the position on the inner peripheral surface 103b side to the center side of the opening 103.
