ることを特徴とする全旋回式車両の警報装置。 Direction detection for detecting the relationship between the forward and backward movement direction of the lower traveling body and the forward direction of a driver's seat attached to the upper rotating body in a fully rotating vehicle in which an upper rotating body is rotatably supported on the lower traveling body. a first switch that becomes conductive when the forward/reverse switching lever provided on the driver's seat is operated in the backward direction of the undercarriage; and the forward/reverse switching lever is operated in the forward direction of the undercarriage. A second switch is provided which conducts when the direction detector detects that the forward direction of the driver's seat and the forward direction of the lower traveling body match, the power supply voltage is supplied to the alarm device via the first switch. By providing a changeover switch that applies the power supply voltage to the alarm device via a second switch when it is detected that the forward direction of the driver's seat matches the backward direction of the lower traveling body,
A warning device for a full-swing type vehicle, characterized in that it operates only when the vehicle travels toward the rear of the driver's seat, regardless of the orientation of the driver's seat with respect to the lower traveling body.
