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： Elongated holes are formed in a first plate of a fixed bracket so as to extend parallel to a column moving direction. An elongated hole inserted portion of a suspending bolt of a suspending mechanism is disposed in an initial assembling position in one of the elongated holes. An inner circumference of the elongated hole includes a pair of flat surface portions which are parallel to the column moving direction, an arc-shaped surface portion and tapered surface portions which connect a pair of end portions of the arc-shaped surface portion to the corresponding flat surface portion. Tapered angles which the tapered surfaces form relative to the column moving direction are equal to or greater than a friction angle.

摘要： A first plate (30) of a stationary bracket (23) has long holes (81, 82) which extend parallel to a column movement direction (XI), and through which large-diameter portions (53) of suspension bolts (251, 252) are passed. The inner circumferences (81a, 82a) of the long holes (81, 82) include: recessed curved surface portions (101, 201) of end portions in a direction (X2) opposite to the column movement direction (XI); first inner edge portions (102, 202) which are on the side of a middle position (CP) between the long holes (81, 82); and second inner edge portions (103, 203). In a secondary collision, when the one suspension bolt (251) slides over the first inner edge portion (102) of the long hole (81), for example, a gap (SS) is formed between the other suspension bolt (252) and the second inner edge portion (203) of the long hole (82).

摘要： A steering column device includes a first tube on an inner side and a second tube on an outer side which are fitted into each other so as to be relatively slidable in an axial direction, and rotatably support a steering shaft. A plurality of projections that come into contact with the inner periphery of the second tube and extend in the axial direction of the first tube are provided on the outer periphery of the first tube. The plurality of projections are disposed at unequal intervals in a peripheral direction of the first tube so as to come close to the vertical plane which includes a central axis line of the first tube.

摘要： A steering system (1) includes an upper jacket (3), a lower jacket (4), a support (2), a lock mechanism (5), and a shock absorber (6). The support (2) supports the lower jacket (4). The lock mechanism (5) switches a restriction of a telescopic adjustment and a termination of the restriction. The upper jacket (3) includes a protruding stopper (31) configured to regulate a position of the upper jacket (3) at one end of a telescopic stroke range. The lock mechanism (5) includes an opening and closing portion (70) configured to enter a path of the stopper (31) while the restriction of the telescopic adjustment is terminated, and configured to open the path of the stopper (31) while the telescopic adjustment is restricted.

摘要： A steering system 1 includes an upper jacket 10 that is movable in an axial direction X, a first stopper member 41 fixed to the upper jacket 10, and a second stopper member 42 on a vehicle body. When a lock and unlock mechanism 4 unlocks the upper jacket 10, the second stopper member 42 moves to an advanced position where the second stopper member 42 faces the first stopper member 41 in the axial direction X. When the lock and unlock mechanism 4 locks the upper jacket 10, the second stopper member 42 moves to a retracted position where the second stopper member 42 retracts from the advanced position.

摘要： A steering column device is provided with a pair of suspension shafts which connects a first plate of a fixed bracket and a second plate of a movable bracket, thereby suspending a movable jacket through the movable bracket. A pair of first holes, each of which is an elongated hole, into which the pair of suspension shafts is inserted, is formed in the first plate. A connection and separation mechanism which separates, at the time of a secondary collision, the second plate from a predetermined position of the first plate in a column movement direction includes a resin pin disposed only between the pair of first holes in relation to a direction (Y1) orthogonal to the column movement direction.
