Claim Text:
1. A steering device by comprising: a steering shaft having one end connected to a steering member, the steering shaft being extendable in an axial direction; a steering column that has an upper column provided on a side of the steering member and a lower column provided on a side opposite to the side of the steering member, the steering column rotatably supporting the steering shaft with the upper column and the lower column and allowing for telescopic adjustment of the steering member by relative displacement of the upper column in the axial direction with respect to the lower column; a support bracket that is provided with an insertion hole elongated in the axial direction, the insertion hole extending in an orthogonal direction that is a lateral direction orthogonal to the axial direction, and the support bracket being fixed to the upper column; a movable tooth member that has a first tooth composed of a plurality of teeth aligned along the axial direction in a rack-shape, and that is inserted into the insertion hole with play in the axial direction to be elastically displaceable to both sides in the axial direction from a predetermined neutral position; a stationary tooth member that has a second tooth provided with teeth engageable with the first tooth, and that is arranged so as to face the movable tooth member in the orthogonal direction; and a lock and release mechanism that moves the stationary tooth member in the orthogonal direction to allow the stationary tooth member to be brought into contact with the movable tooth member or to be separated from the movable tooth member, thereby allowing the second tooth to engage with the first tooth to lock the upper column in the axial direction, or releasing engagement between the first tooth and the second tooth to release lock of the upper column.
