Abstract:
1. A steering device comprising: a first lower column; a second lower column, wherein an inner circumferential surface of the second lower column is secured to an outer circumferential surface of the first lower column by a caulking process; an upper column that engages with the first lower column by a relative sliding axial movement; a female steering shaft axially supported on an upper side of the upper column, and on which a steering wheel facing a rear of a vehicle is mounted; a male steering shaft axially supported on the second lower column to allow rotation by way of a rolling bearing installed on a lower side of the second lower column, and latching with the female steering shaft for movement along an axis relative to the female steering shaft and for transmitting rotational torque, and conveying rotation of the steering wheel to vehicle wheels; a hollow cylindrical bushing with a slit formed along an entire axial length of the bushing and inserted between an inner circumferential surface of the first lower column and an outer circumferential surface of the female steering shaft; and an elastic member inserted between an outer circumferential surface of the bushing and the inner circumferential surface of the first lower column, and that applies a force to reduce a diameter of the bushing, and press an inner circumferential surface of the bushing towards the outer circumferential surface of the female steering shaft.
