摘要： Provided is a steering device including a hollow upper jacket that accommodates a steering shaft, a first engagement member, a rotary shaft that extends in a direction intersecting an axial direction of the steering shaft, and a second engagement member that is a component independent from the rotary shaft. The first engagement member has an engagement hole and is attached to the upper jacket. The second engagement member has an engagement projection which is engageable with the engagement hole. The second engagement member is movable between a lock position where the engagement projection engages with the engagement hole and a release position where the engagement projection is disengaged from the engagement hole, in accordance with a rotation of the rotary shaft. A vertical direction of the second engagement member between the lock position and the release position is different from a rotating direction of the rotary shaft.

摘要： There is provided a steering system that can absorb an increased total amount of shock at a time of a secondary collision and that allows setting an appropriate shock load. A steering member (2) is connected to one end of an upper jacket (7) in a column axial direction (X). A lower jacket (8) is externally fitted with the other end of the upper jacket (7) in the column axial direction (X) so as to be slidable with respect to the upper jacket (7). The lower jacket (8) is supported by a support member (17) fixed to a vehicle body (13). At the time of a secondary collision, a first sliding member (40) generates a first resistive force by performing first relative sliding with respect to the upper jacket (7), and a second sliding member (50) which is moved together with the first sliding member (40) in the column axial direction (X) generates a second resistive force by performing second relative sliding with respect to the support member (17) and the lower jacket (8).

摘要： Provided is a steering apparatus that reduces variations in impact absorbing load caused by differences in a telescopic adjustment position. A first sliding member (40) is held by an upper jacket (7). A second sliding member (50) includes a fixed portion (51) fixed to the first sliding member (40), and an extension portion (52) that extends in a column axis direction (X) and that has a coupled portion (52P) coupled to the fixed portion (51) at a predetermined location in the column axis direction (X). The second sliding member (50) being clamped by the clamping mechanism (18) slides relative to a supporting member (17) and a lower jacket (8) during a secondary impact. The second sliding member (50) includes a slit (54) that reduces coupling stiffness between the fixed portion (51) and the coupled portion (52P) of the extension portion (52) so as to facilitate, in a clamping state of the clamping mechanism (18), deflection of the coupled portion (52P) of the extension portion (52) relative to the fixed portion (51) in a lateral direction as seen from the column axis direction (X).

摘要： Provided is a steering system that is configured to absorb a shock load of a secondary collision by a frictional slide between a slide member configured to move together with an upper jacket and each of a lower jacket and a support member, and is high in vibration rigidity with a simple structure. A lower jacket (8) is externally fitted to an upper jacket (7) in a slidable manner. A support member (17) that supports the lower jacket (8) includes a fixed portion (24) that is fixed to a vehicle body (13). A shock of a secondary collision is absorbed by a shock absorbing mechanism (SA). The shock absorbing mechanism (SA) includes second slide members (50) configured to move together with the upper jacket (7), and to frictionally slide relative to the support member (17) upon a secondary collision. The second slide member (50) includes a sandwiched portion (53) that is sandwiched between the support member (17) and the lower jacket (8), and a transmitting portion (54) that is brought into contact with both of the lower jacket (8) and the support member (17) at a position closer to the fixed portion (24) than the sandwiched portion (53).

摘要： A fulcrum formation member (80) forming a fulcrum and a first spring engagement portion (38) are provided in a bracket (17). A lever link (60) that swings about the fulcrum includes a second spring engagement portion (62) forming a point of load, and an elongated hole (63) in which a fastening shaft (21) is fitted so as to be movable in a longitudinal direction in association with tilt adjustment. A point of effort is located at the edge (63A) of the elongated hole (63). One end (71) of a spring member (70) (biasing member) engages with the first spring engagement portion (38), and the other end (72) thereof engages with the second spring engagement portion (62). The spring member (70) biases a column jacket (8) toward the upper side in a tilt direction via the lever link (60) and the fastening shaft (21).

摘要： A steering system 1 includes a column jacket 4 that can extend and contract in an axial direction X as a result of relative movement between an inner jacket 17 and an outer jacket 18 that houses the inner jacket 17, a regulation member 40 fixed to the outer jacket 18 and passing through an insertion hole 42 in the inner jacket 17, and an elastic member 41 fixed to the outer jacket 18. At the time of vehicular collision, when the regulation member 40 is sheared by a peripheral portion 17D of the insertion hole 42 in the inner jacket 17 in conjunction with the relative movement between the inner jacket 17 and the outer jacket 18, a tip portion 41A of the elastic member 41 is fitted in the insertion hole 42.
