TO LAY OUT A PLURALITY OF TUMBLE DETECTING SENSORS SO THAT A TUMBLE CAN BE ACCURATELY DETECTED, IN AN ATV.[SOLVING MEANS] TUMBLE SENSORS 46 AND 47 ARE BOTH PROVIDED ON THE FRONT LOWER SIDE OF A FUEL TANK 3 AND IN THE VICINITY OF A COLUMN 9 FOR SUPPORTING A STEERING HANDLE. THE TUMBLE SENSOR 46 GENERATES AN OUTPUT CORRESPONDING TO THE INCLINATION IN THE LEFT-RIGHT DIRECTION OF A VEHICLE BODY, WHILE THE TUMBLE SENSOR 47 GENERATES AN OUTPUT CORRESPONDING TO THE INCLINATION IN THE FRONT-REAR DIRECTION OF THE VEHICLE BODY. SPECIFICALLY, THE TUMBLE SENSORS 46 AND 47 ARE LAID OUT SUCH THAT THE EXTENSION LINES OF THE INCLINATION DIRECTIONS TO WHICH THE TUMBLE SENSORS 46 AND 47 RESPOND WITH THEIR MAXIMUM SENSITIVITIES INTERSECT EACH OTHER. IN ADDITION, THE TUMBLE SENSORS 46 AND 47 ARE DISPOSED SUCH THAT THE EXTENSION LINE CONCERNING ONE OF THE SENSORS CROSSES THE OTHER SENSOR; NAMELY, THE TUMBLE SENSORS 46 AND 47 ARE DISPOSED ROUGHLY AT THE SAME POSITION IN THE VEHICLE WIDTH DIRECTION OR IN THE VEHICLE LENGTH DIRECTION.(FIG.1)
