  FIG. 3 shows the roof 10 in a folded state. The roof 10 is connected to the vehicle body 101 via an arm 104. The proximal end of the arm 104 is rotatably supported by the vehicle body 101. The tip of the arm 104 is connected to the link mechanism of the roof 10. The link mechanism operates in conjunction with the rotation of the arm 104. The link mechanism extends or bends the respective bending portions 13, 14 and 15 of the hood 11 according to the rotation direction of the arm 104.

  The end of the printed wiring 2 is connected to the connector 4. The connector portion 4 is, for example, a connector device having an insulating main body and a terminal held by the main body. The connector portion 4 engages with, for example, a connector provided in the circuit 16 on the vehicle body side. The vehicle circuit 1 of the present embodiment has two connector portions 4. One connector portion 4 is connected to one first wiring portion 21, and the other connector portion 4 is connected to the other first wiring portion 22. One connector portion 4 is connected to the power supply 103 via the circuit 16 on the vehicle body side. The other connector 4 is grounded, for example, on the side of the vehicle body 101.

  The power supply 103 is mounted on the vehicle body 101, and is, for example, a secondary battery such as a battery. The circuit 16 on the vehicle body side includes, for example, a wire, a switch, a transformer, and the like. Power is supplied from the power source 103 to the lighting 3 in response to the switch operation by the user. The electric wire of the circuit 16 on the vehicle body side is, for example, routed along the arm 104. The connector portion 4 is disposed in the vicinity of the arm 104. As described above, in the vehicle circuit 1 of the present embodiment, the connector portion 4 is disposed at the connecting portion between the roof 10 and the vehicle body 101. That is, the connector portion 4 is connected to the circuit 16 on the vehicle body side at the connecting portion between the roof 10 and the vehicle body 101.

  As described above, the vehicle circuit 1 of the present embodiment has the printed wiring 2 and the connector portion 4. The printed wiring 2 is formed on a foldable openable roof 10 provided on the vehicle 100. The connector unit 4 is connected to one end of the printed wiring 2. The connector portion 4 is connected to the circuit 16 on the vehicle body side at a connecting portion between the roof 10 and the vehicle body 101 of the vehicle 100. In the circuit for vehicle 1 of the present embodiment, the printed wiring 2 is formed on the foldable openable roof 10.

  According to the printed wiring 2, it is possible to properly route the circuit also to the roof 10 which is folded when it is opened. As a comparative example, it is conceivable to arrange a circuit by a wire, a flexible flat cable (FFC), or a flexible printed circuit (FPC). It is difficult to arrange a circuit by electric wire, FFC, FPC, etc. to the roof 10 folded at the time of opening. On the other hand, the printed wiring 2 can properly arrange a circuit with respect to the roof 10 and does not disturb the opening and closing of the roof 10. Therefore, it is possible to open and close the roof 10 on which the printed wiring 2 is formed without requiring a special opening and closing method. For example, it is possible to add the circuit 1 for vehicles to the roof 10, without requiring the design change of a link mechanism.

  The vehicle circuit 1 of the present embodiment further includes the lighting 3 mounted on the roof 10 and connected to the printed wiring 2. The printed wiring 2 is connected to the power supply 103 via the circuit 16 on the vehicle body side. The illumination 3 is arranged, for example, as a room lamp. According to the circuit for vehicle 1 of the present embodiment, the degree of freedom in the arrangement of the room lamps is improved. For example, as compared with the case where the room lamp is arranged on the vehicle body 101, the degree of freedom in the arrangement of the room lamp in the vehicle longitudinal direction X is improved. Further, since the path of the printed wiring 2 and the mounting of the illumination 3 as an electronic component can be set at an arbitrary place, the brightness / illumination place can be adjusted by the pattern. As a result, the convenience of the user in the car is improved.

  The printed wiring 2 of the present embodiment includes first wiring portions 21 and 22 extending in the vehicle longitudinal direction X in a closed state where the roof 10 covers the compartment of the vehicle 100. In the first wiring portions 21 and 22, a portion located on the vehicle front side of the bending portion 14 (or bending portion 15) of the roof 10, and a portion located on the vehicle rear side of the bending portion 14 (or bending portion 15) Are arranged to be shifted in the vehicle width direction Y. For example, the third extending portion 21c located on the front side of the bending portion 14 and the second extending portion 21b located on the rear side of the bending portion 14 are arranged to be shifted in the vehicle width direction Y.

  With such an arrangement, the second extension portion 21 b and the third extension portion 21 c are prevented from coming into contact when the roof 10 is folded. As a result, the occurrence of a short circuit in the printed wiring 2 is suppressed.

  The roof module 20 of the present embodiment has a roof 10, printed wiring 2, and a connector portion 4. The roof 10 is a foldable openable roof provided on the vehicle 100. The printed wiring 2 is formed on the roof 10. The connector portion 4 is connected to one end of the printed wiring 2, and is connected to the circuit 16 on the vehicle body side at a connecting portion between the roof 10 and the vehicle body 101 of the vehicle 100. According to the roof module 20 of the present embodiment, it is possible to appropriately arrange the circuit on the foldable openable roof 10.

  In addition, in the circuit 1 for vehicles of this embodiment, the connector part 4 may be one. In this case, one of the pair of first wiring portions 21 and 22 may be omitted. The printed wiring 2 may have a plurality of wirings extending in parallel. For example, the printed wiring 2 may have a power supply line and a ground line extending parallel to the power supply line. The printed wiring 2 may further have a communication line extending in parallel to the power supply line and the ground line.

One of the first layer 11A, the second layer 11B, and the third layer 11C may be a heat insulating layer.

  The printed wiring 2 may be formed on a surface different from the inner surface 11a. For example, as shown in FIG. 4, the printed wiring 2 may be formed on the surface of the second layer 11B on the third layer 11C side. The illumination 3 is mounted on the inner surface 11a, for example. In this case, the vehicle circuit 1 preferably has a conductor portion that connects the printed wiring 2 and the light source of the illumination 3.
