摘要:
Collision energy absorbing means of a collision energy absorbing steering column device comprises the following that can change absorption load of secondary collision energy: guide holes (31a1, 31b1, 31a2, 31b2), guide portions (31a3, 31b3), and energy absorbing member (36, 37). In collision of a motor vehicle, a collar (42) causes the energy absorbing member (36 or 37) to deform elastically so that secondary collision energy of a person in the vehicle is absorbed. The guide holes (31a1, 31b1, 31a2, 31b2) and the guide portions (31a3, 31b3) change absorption load of the secondary collision energy depending on the direction of the secondary collision of the person to a steering system.
