A steering system includes a steering column, a column bracket, a distance bracket, a rod, and an elastic member. The steering column supports an input shaft coupled to the steering wheel. The column bracket has a long hole therethrough and supports the steering column. The distance bracket includes: two vertical plates provided on an outer circumferential surface of the steering column and extending along the column bracket; and a horizontal plate coupling together the two vertical plates. The rod penetrates the long hole and the vertical plates. The elastic member is positioned between the horizontal plate and the rod and presses the rod toward the steering column.

Steering system

Construction of a tilt steering apparatus is provided that is capable of preventing the occurrence of unpleasant noise during height adjustment of a steering wheel, and maintains sufficient durability and smooth operation. The tilt steering apparatus of the present invention is provided with stoppersin at least two locations in a buffer memberc that are rotationally symmetric about the center axis of an adjustment rod, and that when a driven-side camis rotated as the axial dimension of a cam apparatusis expanded or contracted, controls rotation of the driven-side camso that a convex engaging portiondoes not collide with the front-side edge or rear-side edge of a vertically long hole

Tilt steering apparatus

Construction is achieved wherein the front-end section of an outer columncan be assembled in the rear-end section of a housingthat houses an electric power steering apparatusfrom below. At least the front-end section of the outer columnis formed into a U shape that is open on the top end. A connection and fastening sectionthat can be inserted inside the front-end section of the outer columnthrough an opening on the top end of the front-end section is provided on the rear-end section of the housing. After the connection and fastening sectionhas been inserted inside the front-end section of the outer columnthrough the opening at the top end of the front-end section, fastening nutsare screwed onto the tip end sections of fastening boltsthat are inserted in the left-right direction through portions near the top ends of the connection and fasting sectionand the front-end section of the outer column, and by tightening the nuts, the connection and fastening sectionand front-end section of the outer columnare connected and fastened together.

Steering apparatus for an automobile

Construction is achieved wherein the front-end section of an outer columnis assembled in the rear-end section of a housingthat houses an electric power steering apparatusfrom below. A block shaped connection and fastening sectionis provided on the rear-end section of the housingA pair of slitsis formed in portions of the connection and fastening sectionnear the left and right ends, and are open on the bottom end surface and rear end surface of the connection and fastening sectionAt least the front-end section of the outer columnhas a pair of side plate sectionsand a bottom plate sectionthat is formed in a U shape that is open at the top. The side plate sectionsare inserted inside the slitsfrom below. In this state, the connection and fastening sectionand the front-end section of the outer columnare connected and fastened by a bolt

In a steering apparatus configured by including: a steering shaft to which a steering wheel can be fitted; a steering column supported on a vehicle body and supporting the steering shaft rotatably; and a combination switch fixedly fitted to the steering column and constructed by combining a plurality of switches having different functions into one integral unit, the improvement comprises: a spacer having an inner peripheral surface that is fixedly fitted onto an outer peripheral surface of an end portion of the steering column on a rear side with respect to a vehicle body and an outer peripheral surface that is formed to have a dimension of an outer diameter enabling an inner peripheral surface of a fitting portion provided in the combination switch to be fitted onto the outer peripheral surface; and a rotation preventive mechanism preventing the spacer from rotating about the steering column. With this configuration, the same combination switch can be fitted to plural types of columns having different dimensions of outer diameters.
