1. An arm stopper mechanism comprising:
a steering arm which turns about an output shaft of a steering apparatus, and to which two tie rods respectively connected to wheels are attached; and a stopper that is provided around the output shaft, and restricts a turning angle of the steering arm, wherein when a center line refers to an imaginary straight line that passes through the output shaft and extends in a longitudinal direction of a vehicle, the steering arm comprises, in a neutral state: an output shaft hole which is provided on the center line, and into which the output shaft is fitted; two tie rod holes which are respectively provided to be positioned rightward and leftward from the center line and rearward from the output shaft hole, and to which the tie rods are respectively attached; and two striking surfaces which are respectively provided to be positioned rightward and leftward from the center line and rearward from the output shaft hole, and which strike against the stopper, wherein the stopper comprises two contact surfaces that are respectively provided to be positioned rightward and leftward from the center line and in a turning direction of the striking surfaces of the steering arm, and are respectively brought into contact with the striking surfaces, and wherein an angle formed by the two contact surfaces of the stopper is greater than an angle formed by the two striking surfaces of the steering arm, and is greater than or equal to 90°. |
