Patent number: 9409591Abstract: A steering device which slides when an impulse load is applied. A steering device includes an inner column having a cylindrical shape, an outer column into which at least a part of the inner column is inserted, a column bracket tightening the outer column, a pressed portion provided on the outer periphery of the inner column, a first tightening mechanism tightening the outer column in response to a rotation of a manipulation lever, a second tightening mechanism biasing a lock member to the pressed portion in a tilt direction in response to the rotation of the manipulation lever, and a separation mechanism. The separation mechanism causes the inner column detachable by changing a relative position between the inner column and the pressing bracket, when the impulse load is applied in a state where the first tightening mechanism and the second tightening mechanism are in work.Type: GrantFiled: October 17, 2014Date of Patent: August 9, 2016Assignee: NSK LTD.Inventors: Masaya Johta, Hideki Kojima, Wataru Hagiwara, Daiki Orihara
