<p>A rear wheel steering system includes: a rear rack shaft (40) that slides in a vehicle-width direction to steer a pair of rear wheels (7); a recess (61) formed in the rear rack shaft (40); and a pin member (63) that is advanced to be fitted into the recess (61) from the outer side of the rear rack shaft (40) and that is retracted to be disengaged from the recess (61). The pin member (63) placed in an advanced state is fitted into the recess (61) to lock sliding of the rear rack shaft (40) in a neutral position, and the pin member (63) placed in a retracted state is disengaged from the recess (61) to cancel slide lock on the rear rack shaft (40). The rear rack shaft (40) has guide grooves (62) formed on respective sides of the recess (61) in a longitudinal direction of the rear rack shaft (40) so as to be contiguous with the recess (61), and used to guide the pin member (63), placed in the advanced state, toward the recess (61).</p> |
