an alarm releasing instruction device that receives an input for releasing the alarm; and
an alarm releasing device that releases the alarm in accordance with a releasing order which is prioritized and predetermined regarding relations between a plurality of regions around the work vehicle and a plurality of running modes of the work vehicle based on an alarm releasing signal from the alarm releasing instruction device,wherein in a case in which;
a highest priority is put on a first alarm region;
alarm sound in the first alarm region is set as high level;
the alarm sound in the first alarm region is notified as the second alarm; and
an operator operates the alarm releasing device, the second alarm is released, the first alarm may be also released along with a release of the second alarm, and the second alarm corresponding to an existence of the mark in the first alarm region is first released.
