PURPOSE:To prevent the mutual effect of the flexture of engaging parts due to flexibly-pressing forces by a constitution wherein the axes of two pinions engaging with one rack are arranged at different angles. CONSTITUTION:A pinion 13a provided on a steering shaft 13 engages with a steering rack 17 for front wheels, and an elastic pressing means 68 is provided on the opposite side to the pinion. Moreover, a connecting shaft 19 for steering rear wheels is engaged with the rack 17 by a pinion 19a, and an elastic pressing means 69 is provided in the same way. These pinions and flexibly-pressing means are provided with the difference in an angle from each other. By this constitution, the flexture of the rack due to the elastic-pressing means 68 and 69 is prevented from affecting the state of engagement of other pinions. |
