In a vehicle configured such that the speed increasing device 9 can be switched from a constant speed operating state to a speed increasing operating state by a speed ratio switching mechanism 19 interlocked with the steering wheel 8, the front axle supporting the front wheels 7 is provided. The case 36 is pivoted so as to be tiltable left and right around a swing axis 39 in the longitudinal direction, and a detection mechanism N is provided to detect the relative left and right tilt angle between the body and the case 36. N
and the speed ratio switching mechanism 19 are interlocked so that when the left and right tilt angle becomes larger than a preset angle, the steering wheel speed increasing device 9 is forced to maintain a constant speed operating state. A vehicle safety device having a steering wheel speed increasing device comprising:
