摘要： A steering column (10) includes: a cylindrical member (20) that holds a steering shaft (15) in such a manner as to allow extension and contraction of the steering shaft; a holding member that holds the cylindrical member; a fixture member (40; 40a) that is fixed to a vehicle body (120); a coupling member (60) that couples the fixture member and the holding member; and an energy absorbing member (50; 50a; 50b) that is partially fixed to the holding member. The coupling member uncouples the fixture member and the holding member when the holding member moves forward for a specified distance in an axial direction. The fixture member has an engaging section (45; 46; 49) arranged at a position where the engaging section is engaged with an engaged section of the energy absorbing member when the holding member moves forward for the specified distance or longer in the axial direction.

摘要： A steering column device includes: an outer tube in which a high rigidity portion and a low rigidity portion are formed; an inner tube disposed in the outer tube; a tubular retainer disposed between the outer tube and the inner tube; at least three protruding portions formed on an outer peripheral surface of the retainer; and a fastening mechanism that regulates relative movement of the outer tube and the inner tube in an axial direction. The at least three protruding portions include: a first protruding portion and a second protruding portion that are disposed so that a midpoint between the first protruding portion and the second protruding portion in a circumferential direction is offset to the high rigidity portion side from a vertical line; and a third protruding portion that is disposed in a region of the low rigidity portion.

摘要： An upper bracket (4) for mounting a column (2) to a vehicle body (6) includes a column support portion (4a) which is press-fitted on an outer periphery of the column through axial press-fitting action with a predetermined interference between the column and the column support portion. Hence, the column (2) is in relative press-fit relation to the bracket (4) and is normally in pressure contact with the column support portion (4a). Therefore, if a secondary collision exerts an impact force on the column (2) pushing the column in the axial direction, the column (2) is moved as generating strong friction with the column support portion (4a). Accordingly, the impact energy of the secondary collision is attenuated by the friction. Thus, a shock absorbing steering apparatus featuring a simple structure ensuring a stable operation can be provided.
摘要翻译： 用于将列（2）安装到车体（6）上的上支架（4）包括柱支撑部分（4a），其通过轴向压配动作以预定的干涉压配合在柱的外周 在柱和柱支撑部之间。 因此，柱（2）与支架（4）处于相对的压配关系，并且通常与柱支撑部分（4a）压力接触。 因此，如果二次碰撞对柱（2）沿轴向推动柱施加冲击力，则柱（2）随着柱支撑部（4a）产生强烈的摩擦而移动。 因此，二次碰撞的冲击能量被摩擦减弱。 因此，可以提供具有确保稳定操作的简单结构的减震转向装置。
