The invention discloses a steering column and an automobile. The steering column comprises a sleeve, a mandrel and a crumpling device. The sleeve is fixed to the body of the automobile. The mandrel is sleeved with the sleeve and is in clearance fit with the sleeve. The two ends of the mandrel extend out of the sleeve. The crumpling device comprises a check ring and an elastic part. The check ring is fixed to the portion, extending out of the sleeve, of the mandrel. One end of the elastic part is connected to the check ring in an abutting mode, and the other end of the elastic part is connected to the sleeve in an abutting mode. The connection portion between the check ring and the mandrel is a crumpling portion which is fractured after bearing the preset axial force. According to the steering column, the sleeve is fixed to the automobile body, and the mandrel is supported on the sleeve through the check ring and the elastic part; when the automobile is severely impacted and the human body collides with a steering wheel, the crumpling portion of the check ring is fractured after bearing the extremely high pressure, the mandrel and the sleeve are disconnected and can freely move, and therefore the steering wheel can move freely as well and will not compress the human body activity space.
