To provide an energy absorbing steering column capable of properly setting a load while moving by a simple and inexpensive structure and facilitating a loading on a vehicle.SOLUTION: An energy absorbing member 30 is placed between a first cylindrical member (inner tube 10) and a second cylindrical member (outer tube 20). This energy absorbing member includes: a small-diameter cylindrical portion 31 which is held in the second cylindrical member and which has an open end abutting a tip of the second cylindrical member; a large-diameter cylindrical portion 32 which is held in the second cylindrical member and which is locked by the second cylindrical member at a predetermined position; and an annular coupling member 33 that integrally couples the large-diameter portion and the small-diameter portion. The second cylindrical member has, for example, multiple pawls (23) that protrude inwardly, and the open end of the large-diameter cylindrical portion is locked by those pawls, and thus a movement of the large-diameter cylindrical portion in an axial direction is prevented.SELECTED DRAWING: Figure 1
【課題】簡単且つ安価な構成で適切に移動中荷重を設定し得ると共に、車両への搭載が容易な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】第1の筒状部材(インナチューブ10)と第2の筒状部材(アウタチューブ20)との間にエネルギー吸収部材30が介装される。このエネルギー吸収部材は、第2の筒状部材に収容され第1の筒状部材の先端部に当接する開口端を有する小径筒部31と、第2の筒状部材に収容され所定位置で第2の筒状部材に係止される大径筒部32と、大径筒部と小径筒部が一体的に連結される環状連結部33とを備えている。第2の筒状部材には、例えば、内側に突出する複数の切り起し(23)が環状に並設されており、これらの切り起しに大径筒部の開口端が係止されて大径筒部の軸方向移動が阻止される。【選択図】図1
