ABSTRACT:
A backlash preventing structure for a steering column is provided for reducing the cost by reducing the number of parts and improving the ease of assembly, and for preventing hammering noise. The steering column has a cylindrical movable jacket slidably fitted into an outer cylindrical housing, the outer cylindrical housing having three holes formed therethrough in an axial direction, a steering shaft swingably disposed within the movable jacket, and a steering wheel secured to one end of the steering shaft. The backlash preventing structure, which prevents backlash of the movable jacket against the outer cylindrical housing, comprises a pair of press members each fitted into a left or a right side hole of the outer cylindrical housing, and a leaf spring fixed to the outer cylindrical housing with a screw screwed into a central hole of the outer cylindrical housing for urging the press members onto an outer peripheral surface of the movable jacket.
