Abstract

A utility vehicle includes traveling devices 11, 12 that support a travel body on a ground surface; a motive power unit provided on the travel body; a power transmission device 20 that transmits motive power from the motive power unit to the traveling devices 11, 12 as travel power; a speed change operation tool 18 that changes a vehicle speed, which is the speed of the travel power, a vehicle speed limiting operation tool 34 that sets an upper limit of the vehicle speed, and a vehicle speed limiting operation prohibition unit 35 that prohibits operation of the vehicle speed limiting operation tool.

Claims (16)

1 . A utility vehicle comprising:

a travel body;

a travel device configured to support the travel body on a ground surface;

a motive power unit provided on the travel body;

a power transmission device configured to transmit motive power from the motive power unit to the travel device as travel power;

a speed change operation tool configured to change a vehicle speed, which is a speed of the travel power;

a vehicle speed limiting operation tool comprising a dial-type operation tool configured to set an upper limit of the vehicle speed;

a vehicle speed limiting operation prohibition unit configured to selectively prohibit operation of the vehicle speed limiting operation tool; and

a vehicle speed upper limit display section configured to indicate the upper limit set by the vehicle speed limiting operation tool,

wherein the vehicle speed limiting operation prohibition unit is configured as an attachment and detachment mechanism for attaching and detaching the vehicle speed limiting operation tool to and from a member included in the travel body,

wherein even after the vehicle speed limiting operation tool is detached from the travel body, the vehicle speed upper limit display section is held in the travel body,

wherein the vehicle speed upper limit display section has a vehicle speed upper limit indicator mechanically linked to operation of the vehicle speed limiting operation tool, and

wherein the vehicle speed limiting operation tool, the vehicle speed limiting operation prohibition unit, and the vehicle speed upper limit indicator are integral.

2 . The utility vehicle according to claim 1 ,

further comprising a gear shift control system, wherein the gear shift control system comprises a power control unit and a gear shift control unit, and the gear shift control unit comprises a vehicle speed limit management unit,

wherein the vehicle speed limit management unit generates a vehicle speed limit command based on a vehicle speed control command generated through an operation on the vehicle speed limit operation tool, the vehicle speed limit command is recorded by the vehicle speed limit management unit, and when a new vehicle speed limit command is input, the recorded vehicle speed limit command is overwritten with the new vehicle speed limit command.
