A throttle operating device includes a fixing member, a throttle lever, and a detection sensor. A drive source of the transport is configured to be controlled based on the rotational operation angle of the throttle lever detected by the detection sensor. The throttle lever is configured to be rotated in a forward direction and a reverse direction. When the throttle lever is rotated in the forward direction, the drive source of the transport can be controlled. When the throttle lever is rotated in the reverse direction, a predetermined device mounted on the transport can be operated or an operation of the predetermined device can be stopped.
