摘要： 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 1, and maintains sufficient durability and smooth operation. The tilt steering apparatus of the present invention is provided with stoppers 65 in at least two locations in a buffer member 21 c that are rotationally symmetric about the center axis of an adjustment rod 14, and that when a driven-side cam 15b is rotated as the axial dimension of a cam apparatus 47 is expanded or contracted, controls rotation of the driven-side cam 15b so that a convex engaging portion 39c does not collide with the front-side edge or rear-side edge of a vertically long hole 35b.

摘要： 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.
