摘要： A steering column device includes: an outer tube in which a high rigidity portion and a low rigidity portion are formed; an inner tube disposed in the outer tube; a tubular retainer disposed between the outer tube and the inner tube; at least three protruding portions formed on an outer peripheral surface of the retainer; and a fastening mechanism that regulates relative movement of the outer tube and the inner tube in an axial direction. The at least three protruding portions include: a first protruding portion and a second protruding portion that are disposed so that a midpoint between the first protruding portion and the second protruding portion in a circumferential direction is offset to the high rigidity portion side from a vertical line; and a third protruding portion that is disposed in a region of the low rigidity portion.

摘要： A steering system includes a steering shaft, a fixed bracket, a column jacket, and a lock mechanism. The lock mechanism includes an insertion shaft, an operation member, a first pressing member, a second pressing member, and a drive mechanism. The lock mechanism is configured to lock a position of the column jacket relative to the fixed bracket after the tilt adjustment. The drive mechanism is configured to move at least one of the first pressing member and the second pressing member so that the first pressing member and the second pressing member approach each other in an insertion axis direction of the insertion shaft along with rotation of the operation member.
