Abstract
A steering apparatus for a four-wheeled vehicle transmits a steering force through a steering shaft, a reduction gear, a steering lever and right and left tie rods to right and left knuckles. The reduction gear includes a pinion gear turned by the steering shaft, a steering gear engaged with the pinion gear and fixedly mounted on a lever shaft, which is combined with the steering lever, and a gear case housing the pinion gear and the steering gear. The lever shaft has a first end portion supported in a bearing held on the gear case. The bearing permits the lever shaft to be turned therein. The lever has a second end portion supported in a bearing hole that permits the second end portion to be shifted in the back-and-forth direction. The second end portion of the lever shaft is biased by a spring so as to press the steering gear against the pinion gear so that no backlash is formed between the pinion gear and the steering gear.
