摘要： A steering system (1) includes a fastening mechanism (7) that makes an upper jacket (15) fastened to be held by a lower jacket (16). In a fastened state of the fastening mechanism (7), a first tooth member (60) on the upper jacket (15) side is meshed with a second tooth member (70) on the lower jacket side (16). The second tooth member (70) is connected to the lower jacket (16) via a guide shaft (80, connecting member) that is fracturable during a secondary collision. During the secondary collision in an unfastened state of the fastening mechanism (7), a second engagement portion (180, driving member) that moves in a column axial direction integrally with the upper jacket (15) abuts on the second tooth member (70) in an unmeshed state to fracture the guide shaft (80), and deforms an impact absorbing member (40) via the second tooth member (70) to absorb an impact.

摘要： In a steering system, a pair of side plates (30) of an upper bracket (6) support first tooth rows (71) each including a plurality of first teeth (72) arranged at a pitch and second tooth rows (97) each including a plurality of second teeth (96) arranged at the pitch. An insertion shaft supports third teeth (82) that can come into and out of contact with the first tooth rows (71) and fourth teeth (98) that can come into and out of contact with the second tooth rows (97). One pair out of a pair of the tooth tip (72A) of each first tooth (72) and the tooth tip (96A) of the corresponding second tooth (96) and a pair of the tooth tip (82A) of each third tooth (82) and the tooth tip (98A) of the corresponding fourth tooth (98) are in the same position in a tilt direction, and the other pair are displaced from each other by a length smaller than the pitch in the tilt direction.

摘要： A steering system includes an insertion shaft that is movable in a tilt direction (C) along with a column jacket, a first tooth member (43) including a plurality of first teeth (51) aligned along a first linear direction, and a second tooth member (45) including a plurality of second teeth (63) aligned along the first linear direction. A first restriction portion (55) restricts movement of the first tooth member (43) in the first linear direction with respect to an upper bracket. A second restriction portion (58) is movable in the first linear direction and immovable in a second linear direction, with respect to a linear slot (52) in the first tooth member (43) that extends along the first linear direction. The second restriction portion (58) restricts movement of the second tooth member (45) in the second linear direction with respect to the first tooth member (43).
