[0003] [Patent Document 1] JP 2017-047796 A Summary of the Invention [Problem to be solved by the invention]

[0004] In such a multi-purpose vehicle, when an optional item that requires power supply from the battery is installed, power is conducted from the battery to the optional device via the bus bar. In this case, wiring from the battery to the bus bar is required. However, in conventional multi-purpose vehicles, the wiring can become complicated depending on the positional relationship from the battery to the bus bar.

[0005] Also, there are cases where the installation of an optional item that requires a supply of power from a battery is not required, and in such cases, there is the inconvenience of an unnecessary bus bar remaining installed.

[0006] An object of the present invention is to provide a multi-purpose vehicle that can be configured without a bus bar when there is no need to supply power from the battery, and that avoids complicated wiring between the battery and the bus bar. [Means for solving the problem]

[0007] The multi-purpose vehicle of the present invention comprises a vehicle body, left and right body frames that constitute the vehicle body, a battery that supplies power to optional equipment that can be retrofitted to the vehicle body, and a mounting portion to which a bus bar for conducting current from the battery to the optional equipment is detachably attached, and the bus bar attached to the mounting portion is located above the battery.

[0008] According to this invention, since the bus bar is detachably attached to the mounting portion, when power supply from the battery is not required, the configuration can be such that the bus bar is not provided. Also, since the bus bar attached to the mounting portion is located above the battery, the wiring between the battery and the bus bar can be simplified, and it is possible to avoid the wiring between the battery and the bus bar becoming complicated.

[0009] In the present invention, it is preferable that a seat on which a passenger can sit is provided, the battery is positioned below the seat, and the attachment portion is positioned behind the seat.

[0010] According to this configuration, the wiring between the battery and the bus bar is arranged in the space below and behind the seat, which makes it possible to utilize the space below and behind the seat for wiring between the battery and the bus bar.

[0011] In the present invention, it is preferable that upper and lower frames are provided which are supported by the body frame and extend in the vertical direction, and the mounting portion is provided on the upper and lower frames.

[0012] According to this configuration, the bus bar attached to the mounting portion is supported by the vehicle body frame via the upper and lower frames, making it possible to provide a configuration in which the bus bar is firmly supported.

[0013] In the present invention, it is preferable that the battery and the upper and lower frames are supported by one of the left and right vehicle body frames.

[0014] With this configuration, the upper and lower frames that support the battery and the mounting part are disposed on one side of the left or right body frame, so that the battery and the mounting part are disposed closer to each other, and as a result, the wiring between the battery and the bus bar can be made more compact.

[0015] In the present invention, it is preferable that the bus bar is attached to the attachment portion via a stay.

[0016] According to this configuration, the bus bar is attached to the mounting portion via the stay, and since the bus bar is attached to the mounting portion without directly tightening a bolt to the bus bar, damage to the bus bar that may accompany such an attachment operation can be reduced.

[0017] In the present invention, it is preferable that the stay is provided with a flat portion covering the bus bar from above.

[0018] According to this configuration, the flat portion can protect the bus bar from raindrops, flying debris, and the like from above. Also, the stay is configured to have a flat portion at a location different from the location where the bus bar is attached. This configuration can increase the strength of the stay.

[0019] In the present invention, it is preferable that the stay is fastened to the mounting portion by using a fastening member.

[0020] According to this configuration, the stay can be easily attached to and detached from the mounting portion by using a fastening member such as a bolt. [Brief description of the drawings]
