By engaging the temporary fixing portion of the temporary fixing pin with both the rotor-side engaging portion and the stator-side engaging portion, the rotor and the stator can be temporarily fixed at the neutral position. Further, by engaging the wiring connector for connecting to the vehicle connected to the rotor with the cap portion of the temporary fixing pin, the wiring connector can be dust-proof.

[0010] Therefore, the temporary fixing pin and the vehicle are connected.
Compared with the conventional temporary fixing device of a roll connector, which separately manufactures the dustproof cap of the wiring connector for the wiring connector and removes both after attaching to the vehicle, the temporary fixing pin and the dustproof cap are integrated, The number of points can be reduced and cost increase can be suppressed.

According to the second aspect of the present invention, the stator and the rotor are temporarily fixed to the neutral position by the fixing means until the roll connector for connecting to the vehicle is attached to the vehicle. The wiring connector is fixed at a position where at least one of the stator and the rotor closes the opening of the wiring connector.

Therefore, both the temporary fixing pin used in the conventional roll connector temporary fixing device and the dustproof cap of the wiring connector for connecting to the vehicle can be eliminated, thereby reducing the number of parts and increasing the cost. Can be suppressed.
