Abstract

A telescopic device includes an inner tube; an outer tube having an opening formed on an end so that the opening partially extends in a longitudinal direction; upper mounting brackets; a lever; and a protruding distance member fixed to an outer peripheral surface of the outer tube and provided with a protrusion inserted into the opening and fasteners to be mounted on the upper mounting brackets. The protrusion is adapted to compress the inner tube when the lever is fastened so that the inner and outer tubes are fixed to each other. By replacing the conventional telescopic bush with the distance member, the telescopic force is reduced when the lever is unfastened. In addition, when the lever is fastened, the inner peripheral surface and the protruding surface of the distance member strongly compress both the outer and inner tubes. This increases the rigidity of the steering device during driving.

Description

technical field [0001] The present invention relates to a telescoping device with protruding spacer members. In particular, the present invention relates to a telescoping device having a protruding spacer member that can replace a conventional injection-molded plastic telescoping bushing, the protruding spacer member having a protrusion formed at a predetermined position on a portion of its inner exterior surface, where the adjustment lever After being fastened, the protruding part penetrates the outer cylinder and presses the inner cylinder to enhance the joint strength of the outer cylinder and the inner cylinder. Background technique [0002] Those who are familiar with the field of automobiles know that a car includes a steering column installed in front of the driver's seat for transmitting the rotational force of the steering wheel to the wheels through the gearbox, and a tilting and telescopic device that adjusts the position of the steering wheel according to the dri...
