- a steering column to be arranged in an upwardly inclined orientation and supporting rotatably a steering shaft for transmitting turning force of a steering wheel to a gear box unit;
a first steering column supporting member to be fixed to a body of the vehicle and supporting an upper part of said steering column at a fixed position;
a second steering column supporting member for releasably connecting a lower part of said steering column to a member on the body side; and

Abstract
An upper part of a steering column is supported by a first supporting member and a lower part of the steering column is connected releasably to a car body by a second supporting member. Such component state is released by a releasing device which detects a predetermined state of collision upon the occurrence of a collision. This arrangement restricts the extent of rearward movement of a steering wheel and adjusts properly the amount of upward movement of the steering handle, thereby contributing to the improvement of safety.
