A handle lever steering device including a handle lever and a pair of knuckle arms pivotally supported by a frame and constituting the Ackermann mechanism has a rod end secured to a rotary shaft for supporting the handle lever and having a first support shaft and a second support shaft. The first support shaft is connected to a support shaft connected to an arm of one of the left and right knuckle arms, and the second support shaft is connected to a support shaft connected to an arm of the other knuckle arm. The first and second support shafts and the rotary shaft for supporting the handle lever are located on an imaginary straight line. The ratio of the distance Yl between the center of the rotary shaft for supporting the handle lever and the center of the first support shaft to the distance Xl between the center of the support shaft connected to the arm of one knuckle arm connected to the first support shaft and the center of a rotary shaft for supporting the one knuckle arm is substantially equal to the ratio of the distance Yr between the center of the rotary shaft for supporting the handle lever and the center of the second support shaft to the distance Xr between the center of the support shaft connected to the arm of the other knuckle arm connected to the second support shaft and the center of a rotary shaft for supporting the other knuckle arm. |
