PROBLEM TO BE SOLVED: To provide a steering shaft support structure that allows a steering shaft to be securely detached at the time of a collision and allows the shaft from interfering with surrounding components by controlling a detachment direction.SOLUTION: The steering shaft support structure comprises at a region in front of a vehicle interior a support member 21 for supporting a steering shaft s3 to a vehicle body-side member 19. The supporting member 21 has: a lower dividing member 23 that is fixed to the vehicle body-side member 19 and supports an intermediate support part A of the steering shaft s3 from below; and an upper dividing member 22 that is extended in a vehicle width direction Y and whose both ends are locked to the lower dividing member 23 and sandwiches and holds the intermediate support part A from above. At an end part outside in the vehicle width direction Y of the upper dividing member 22 is provided a locking claw 223 which is locked to the lower dividing member 23 and deformed to be detached from the lower dividing member 23 when being applied with a load from the steering shaft s3.SELECTED DRAWING: Figure 4
【課題】衝突時におけるステアリングシャフトの離脱を確実とし、かつ離脱方向をコントロールして周辺部品との干渉を抑制することができるステアリングシャフト支持構造を提供する。【解決手段】車室前方の領域において、ステアリングシャフトs3を車体側の部材19に支持する支持部材21を備え、支持部材21は、車体側の部材19に固定されてステアリングシャフトs3の中間支持部Aを下方側から支持する下分割部材23と、車幅方向Yに延設されるとともに両端部が下分割部材23に係止され、中間支持部Aを上方から挟んで保持する上分割部材22とを有し、上分割部材22の車幅方向Y外側の端部には、下分割部材23に係止され、ステアリングシャフトs3から荷重が作用された際に変形して下分割部材23から離脱される係止爪223が設けられている。【選択図】図4
