PROBLEM TO BE SOLVED: To provide an energy absorption steering column provided with a mechanism that can be configured into a unit and easily attached to two cylindrical members as an energy absorption mechanism that absorbs energy when the two cylindrical members move relatively to each other in the axial direction.SOLUTION: An energy absorption steering column configures an energy absorption unit that comprises a plate member 30 formed to be bent into a U-shape and a support member 40 having a holding section 41 which holds one free end portion of the plate member at a predetermined position and a guide part 43 guiding the other free end portion thereof to be slidable, the support member is locked to an opening end portion of a second cylindrical member and the plate member is fixed to a first cylindrical member in a state where the plate member is held by the support member. When a load exceeding a predetermined amount is applied to a steering shaft, the holding state of the plate member is cancelled.SELECTED DRAWING: Figure 3
【課題】二つの筒状部材の軸方向相対移動時のエネルギーを吸収するエネルギー吸収機構として、ユニット構成が可能で、当該筒状部材に容易に取り付け得る機構を備えたエネルギー吸収ステアリングコラムを提供する。【解決手段】U字状に屈曲形成された板状部材30と、その一方の自由端部を所定位置に保持する保持部41及び他方の自由端部を摺動可能に案内する案内部43を有する支持部材40とを備えたエネルギー吸収ユニットを構成し、支持部材に板状部材を保持した状態で、支持部材を第2筒状部材の開口端部に係止すると共に、板状部材を第1筒状部材に固定する。ステアリングシャフトに所定値を越える荷重が印加されたときには板状部材の保持状態が解除される。【選択図】図3
