发明名称 STEERING DEVICE
摘要 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.

主权项 1. A steering device comprising: an inner column having a cylindrical shape and rotatably supporting an input shaft connected to a steering wheel; an outer column having a cylindrical shape into which at least a part of the inner column is inserted, and having a slit formed by notching one end thereof at which the inner column is inserted; a column bracket fixed to a vehicle body side member and tightening the outer column by a pressing bracket squeezing 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 causing the inner column to be detachable when the inner column changes a relative position with respect to the pressing bracket, in a state where the first tightening mechanism tightens the outer column and the second tightening mechanism biases the lock member to the pressed portion in the tilt direction.
