STEERING SYSTEM

摘要

A steering system includes an upper bracket having a first tooth row, a rigid tooth member, a second tooth row provided on the tooth member, a first moving member, and an elastic member disposed between the tooth member and the first moving member. The first tooth row includes a plurality of first teeth. The second tooth row includes a plurality of second teeth. The elastic member exerts a constant restoration force. The second tooth row meshes with the first tooth row when the first teeth and the second teeth are alternately arranged in a tilt direction.

主权项

1. A steering system comprising:
a steering member; a column jacket that holds a steering shaft with the steering member coupled to one end of the steering shaft and that is movable in a tilt direction intersecting an axial direction of the steering shaft in an up-down direction in order to position the steering member in the tilt direction; a bracket that has a first tooth row including a plurality of first teeth arranged along the tilt direction, and that is fixed to a vehicle body to support the column jacket; an operation member that is operated for the positioning; a rigid tooth member that is provided adjacent to the bracket in a direction orthogonal to both the axial direction and the tilt direction and that is movable in the tilt direction along with the column jacket and movable in the orthogonal direction; a second tooth row that is provided on a surface of the tooth member facing the first tooth row in the orthogonal direction and that includes a plurality of second teeth arranged along the tilt direction, the second tooth row meshing with the first tooth row when the first teeth and the second teeth are alternately arranged in the tilt direction; a moving member that is disposed on the opposite side of the tooth member from the bracket in the orthogonal direction and that is movable in the orthogonal direction in accordance with an operation of the operation member; and an elastic member disposed between the tooth member and the moving member, and within a predetermined range where the moving member moves toward the bracket, exerting a constant restoration force while being compressed in the orthogonal direction.
