A steering gear mechanism has in combination a housing, a pinion shaft rotatably in the interior of the housing and provided with a pinion thereon; a slidable rack bar guided the housing and formed on one surface thereof with a rack adapted to operatively engage with the pinion, and a friction device adapted to give rise to a relatively large frictional force in the directions of sliding motion of the rack bar in the neutral steering position, while giving rise to a relatively small frictational force in the same direction of sliding motion within the normal range of the steering operation of the rack bar. |
