  • the electric brake device is provided with multiple connectors having the above-mentioned functions, but the detailed positional relationship of each connector is unknown.

In addition, since the positions of each connector differ on the left and right sides of the vehicle body, it is necessary to design an outline that can be mounted on either of the pair of left and right wheels. Furthermore, if an outline is designed for each of the pair of left and right wheels to maximize the use of mounting space on the vehicle, unique parts will be required for each pair of left and right wheels, which may increase costs.
