PROBLEM TO BE SOLVED: To automatically decelerate the traveling speed even when a steering wheel is largely operated while traveling at a high speed by changing the change gear ratio of a continuously variable transmission for traveling to a lower speed side as the operation angle of the steering wheel is increased. SOLUTION: A forward end of a third bell crank 125 is interlockingly connected to a thirteenth lever 128 through an eleventh connecting rod 129. A forward end of a fourteenth lever 130 projected on a rear end of a longitudinal torsion bar 127 is interlockingly connected to a left end of a fourth bell crank 131 through a twelfth connecting rod 132. A lower end of a thirteenth connecting rod 133 is interlockingly connected to a right end of the fourth bell crank 131, and an upper end of the thirteenth connecting rod 133 is interlockingly connected to a right end part of a base end block 72. When the operation angle of a steering wheel exceeds a range set by an oblong hole 123, the operation of the steering wheel is transmitted to the base end block 72 to tilt the base end block 72, and the change gear ratio of a continuously variable transmission 21 is moved to a lower speed side. |
