Patent number: 11427244Abstract: A support bracket is arranged inside a slit of an outer column and joined to the inner column so as to be able to detach due to an impact load applied to the inner column at the time of a secondary collision. A base portion of an impact absorbing member is attached to the inner column so as to displace together with the inner column when the inner column displaces toward the front, and a folded portion of the impact absorbing member is made to face a jerking portion of the support bracket in the front-rear direction.Type: GrantFiled: October 24, 2019Date of Patent: August 30, 2022Assignee: NSK LTD.Inventors: Nobuhiro Kojiya, Arata Urimoto, Masaya Johta, Seiichi Moriyama

Patent number: 9623895Abstract: A steering device includes a cylindrical inner column, a cylindrical outer column, a column bracket, a tilt bolt, a lock member attached to the outer periphery of the tilt bolt, a first fixing mechanism, and a second fixing mechanism. The first fixing mechanism clamps the outer column by a pressing bracket in response to the rotation of an operation lever. The second fixing mechanism urges the lock member to the inner column in the tilt direction in response to the rotation of the operation lever. When the inner column moves toward a front side of a vehicle body in a state where the first fixing mechanism and the second fixing mechanism are fixed, the lock member separates from the tilt bolt.Type: GrantFiled: February 27, 2015Date of Patent: April 18, 2017Assignee: NSK LTD.Inventors: Masaya Johta, Daiki Orihara, Ryoichi Suzuki
