Claims

[Claims for Utility Model Registration] (1) An outer column and an inner column, each formed in a cylindrical shape and combined with each other in a telescopic manner, and a portion of which protrudes to the side of the outer column to serve as a protrusion. , a lock housing fixed to the intermediate portion of the outer column, a cylinder space provided inside the protrusion, a communication opening that communicates the cylinder space with the inside of the outer column, and a communication opening in the cylinder space. a lock member that is housed and comes into contact with the outer peripheral surface of the inner column exposed toward the cylinder space at the communication opening portion, a male screw on the outer peripheral surface and a female screw on the inner peripheral surface;
By screwing the male screw into a screw hole formed in a partition wall that partitions the outer surface of the cylinder space, a cylindrical adjustment nut supported on the partition wall and a cylindrical adjuster nut supported on the partition wall are connected to each other on the outside of the partition wall. , a lock nut screwed onto the male thread on the outer circumferential surface of the adjusting nut, a lock screw screwed onto the female thread on the inner circumferential surface of the adjusting nut and whose tip end is engaged with the lock member, and a base end portion of the lock screw. A telescoping steering column device consisting of an adjustment lever fixed to the (2) A screw hole is formed in the center of the locking member in the opposite direction to the female screw formed on the inner circumferential surface of the adjusting nut, and the first male screw formed in the middle portion of the locking screw is inserted into the female screw hole on the inner circumferential surface of the adjusting nut. 2. The telescoping steering column device according to claim 1, wherein the second male screw portion formed at the tip of the lock screw is screwed into the screw hole, respectively. (3) A claim in which, instead of omitting the female screw formed on the inner circumferential surface of the adjusting nut and the first male screw formed at the intermediate portion of the locking screw, the locking screw is supported inside the adjusting nut so that it can only rotate freely. 2
