Abstract
A vehicle steering column is comprised of a lower column mounted to undergo angular displacement around one end portion thereof and an upper column telescopically connected to the other end portion of the lower column to undergo angular displacement together with the lower column and linear displacement relative to the lower column along a column axis. A plurality of ball members are disposed between the lower and upper columns for restraining free linear displacement of the upper column to thereby allow the upper column to undergo frictional linear displacement in response to the application of a given amount of force to the upper column. A support member is engaged with the upper column for restraining free angular displacement of the upper column to thereby allow the upper column to undergo stepwise angular displacement in response to the application of a given amount of force to the upper column.
