PROBLEM TO BE SOLVED: To provide a rolling prevention device of a stop vehicle capable of surely eliminating rolling travel when the vehicle stops on a sloping road and reducing the time and labor required by works of rolling prevention and its release. SOLUTION: A front horizontal hydraulic cylinder 2 and a rear horizontal hydraulic cylinder 3 are arranged in the lower part of a vehicle body 11 between a front tire 9 and a rear tire 10 of a truck 1. Each hydraulic cylinder 2, 3 is connected by a cylinder connection member 4. The cylinder connection member 4 is lifted and lowered freely by hydraulic cylinders 5, 6 for elevation. Triangular wedge bodies 7a, 8a are attached to tips of each cylinder rod 2a, 3a of the front horizontal hydraulic cylinder 2 and the rear horizontal hydraulic cylinder 3. The front and rear horizontal hydraulic cylinders 2, 3 are lowered down to the vicinity of the ground by the hydraulic cylinders 5, 6 when the vehicle stops. The cylinder rods 2a, 3a are elongated to insert the wedge bodies 7a, 8a at the tips between the tires 9, 10 and the ground surface. COPYRIGHT: (C)2004,JPO
