ABSTRACT:
A locking structure of a steering column. A main housing is provided around a steering shaft and fixed to a car body. An insert pipe protrudes from the main housing. A sliding housing has an arc portion surrounding the insert pipe, a tightening block at each end, and a variable inner cross-section that changes with distance between the tightening blocks. An upper housing is tiltable relative to the sliding housing. A tilt plate is fixed to the upper housing, extends to the tightening block, and has an arc-shaped slot corresponding to a rotation distance of the tilt plate. A locking bolt passes through the arc-shaped slot of the tilt plate and through the tightening blocks. An operation lever is rotatably fitted on the locking bolt. A cam assembly variably applies a force to the tilt plates and the tightening blocks according to a rotation distance of the operation lever.
