Steering gear 88 converts the rotational motion transmitted to pinion 88a into linear motion using rack 88b. Rack 88b is connected to tie rod 89. That is, the steering device 80 is of a rack and pinion type.

The steering force assist mechanism 83 includes a speed reduction device 92 and an electric motor 93. The electric motor 93 is, for example, a brushless motor, but may also be a motor equipped with a brush (slider) and a commutator (commutator). The speed reduction device 92 is, for example, a worm speed reduction device. The torque generated by the electric motor 93 is transmitted to the worm wheel via the worm inside the reduction gear 92, and rotates the worm wheel. The speed reducer 92 uses a worm and a worm wheel to increase the torque generated by the electric motor 93. The speed reducer 92 then applies auxiliary steering torque to the output shaft 82b. That is, the steering device 80 is of a column assist type.

As shown in FIG. 4, the operating lever 1 includes a lever body 11 and a knob portion 12, and extends along the longitudinal direction D1. The lever main body 11 includes one end portion 110, the other end portion 120, and an intermediate portion 130. A square hole 111 is provided in one end portion 110, and a rotating cam 27 shown in FIG. 3 is fitted into the square hole 111. That is, one end portion 110 of the lever body 11 is rotatably supported by the side plate 24 via the rotating cam 27 and the tilt rod 26. The other end 120 is provided with a first notch 3 and a second notch 4, which will be described in detail later.

The intermediate portion 130 extends from the first bent portion 141 to the third bent portion 143 via the second bent portion 142 . The other end 120 extends from the third bent portion 143 to the other end 113 . As shown in FIG. 5, the other end portion 120 is inclined in the plate thickness direction D2 with respect to a portion from the second bent portion 142 to the third bent portion 143. This inclination makes it difficult for the knob portion 12 to come off from the lever body 11. Note that, as shown in FIG. 5, the longitudinal direction D1 and the plate thickness direction D2 are orthogonal to each other, and as shown in FIG. 4, the longitudinal direction D1 and the width direction D3 are orthogonal to each other.

That is, the first notch 3 and the second notch 4 are arranged as a pair on both sides of the lever body 11 in the width direction D3.

The edge of the other end 120 of the lever body 11 is the first edge 30. The first edge 30 is the other end 113 described above and extends along the width direction D3. The first edge 30 extends from the first corner 31 to the second corner 32. For example, when the position of the steering wheel 81 is fixed (when the operating lever 1 is at the uppermost position), the first edge 30 is along the vertical direction. Note that a curved arcuate portion 34 is formed from the second corner portion 32 to the third corner portion 33. The edge of the first notch 3 includes a second edge 35, a third edge 36, and an inner edge 37. The second edge 35 and the third edge 36 extend along the first edge 30.

The inner edge 43 extends along the longitudinal direction D1. The fourth edge 41, the fifth edge 42, and the inner edge 43 form a U-shape.

FIG. 7 is a side view showing the end of the lever main body of the operating lever according to the first embodiment, and shows a state in which a rotational moment is applied to the end of the lever main body. First, an axis C that includes the center of the first notch 3 and the second notch 4 in the width direction D3 and extends in the thickness direction D2 of the lever body 11 (see FIG. 5) is virtually set. When an occupant grips the knob portion 12 and rotates the operating lever 1 in the downward arrow direction 100, the knob portion 12 attempts to rotate relative to the lever body 11 about the axis C. Then, forces 101 and 102 (indicated by arrows) are applied to the resin portion of the knob portion 12 to press the first edge 30, second edge 35, and fifth edge 42. Since the input direction of the forces 101 and 102 is substantially orthogonal to the second edge 35 and the fifth edge 42, the forces 101 and 102 of the knob portion 12 can be received by the second edge 35 and the fifth edge 42. As described above, the rotational moment described above is the force 101, 102 that causes the resin portion of the knob portion 12 to rotate the other end portion 120 of the lever body 11 about the axis C.

As explained above, the operating lever 1 of the first embodiment includes the lever body 11 made of a metal plate, and the knob part 12 made of resin provided at the end of the lever body 11 in the longitudinal direction D1, The other end 120 (end) of the lever main body 11 in the longitudinal direction D1 is a first notch 3 disposed at one end in the width direction D3 perpendicular to the longitudinal direction D1 and the plate thickness direction D2 of the lever main body 11. and a second notch 4 arranged at the other end in the width direction D3, and the first notch 3 and the second notch 4 are covered with a knob part 12.

According to this, the first notch 3 and the second notch 4 are provided at the end of the lever body 11 in the longitudinal direction D1, and the first notch 3 and the second notch 4 are covered by the knob part 12. It is being said. For this reason, since the knob portion 12 is held by the resin portion covering the first notch portion 3 and the second notch portion 4, when a load is applied to the knob portion 12, the knob portion 12 is held at the end of the lever body 11. It is suppressed from coming off from the section. Moreover, since the first notch 3 and the second notch 4 are provided at the end in the width direction D3, the weight of the entire operating lever 1 can be made smaller compared to the operating lever of Patent Document 1. As described above, according to the present disclosure, it is possible to provide the steering device 80 that includes the operating lever 1 that reduces the weight while suppressing the knob portion 12 from coming off the lever body 11.

Further, the first notch 3 includes a second edge 35 and a third edge 36 that extend along the first edge 30 that is the edge in the longitudinal direction D1 of the lever main body 11, and the second notch 4 includes a It includes a fourth edge 41 and a fifth edge 42 extending along one edge 30.

The second edge 35 and the third edge 36 of the first notch 3 and the fourth edge 41 and the fifth edge 42 of the second notch 4 all extend along the first edge 30. Here, when swinging the lever body 11 to one side in the circumferential direction centering on the tilt rod 26, the axis C located at the center in the width direction D3 between the first notch 3 and the second notch 4 is the center. As a result, the knob portion 12 attempts to rotate. Then, the resin portion of the knob portion 12 presses the first edge 30, the second edge 35, and the fifth edge 42. Further, when swinging to the other side in the circumferential direction, the resin portion of the knob portion 12 presses the first edge 30, the third edge 36, and the fourth edge 41. In this way, the friction between the first edge 30 of the lever body 11, the second edge 35 and third edge 36 of the first notch 3, and the fourth edge 41 and fifth edge 42 of the second notch 4 increases. Therefore, the knob portion 12 is further prevented from coming off the lever body 11, and the bending rigidity of the lever body 11 is improved.

As shown in FIG. 14, the lever main body 11E according to the third reference example includes one end portion 110E, the other end portion 120E, and an intermediate portion 130E. A square hole 111E is provided in one end portion 110E. A rib 131E is provided in the middle portion.

A V-shaped protrusion 54 is provided at the other end 120E (end) of the lever body 11E. The protrusion 54 includes two legs 541 and 542 that protrude toward the other end in the longitudinal direction. A notch 55 is formed between the two legs 541 and 542. The edge of the other end 120E of the lever body 11E is the first edge 30E, which is the edge of the protrusion 54.

As explained above, in the third reference example, the rotational moment applied to the other end 120E of the lever body 11E is applied to the V-shaped protrusion 54, so that the knob part 12 does not come off from the lever body 11E. This is further suppressed and the bending rigidity of the lever body 11E is improved.

[Fourth reference example]
FIG. 15 is a side view of a lever main body according to a fourth reference example. As shown in FIG. 15, the lever main body 11F according to the fourth reference example includes one end portion 110F, the other end portion 120F, and an intermediate portion 130F. A square hole 111F is provided in one end portion 110F. A rib 131F is provided in the intermediate portion 130F.

A notch 56 is provided at the other end 120F (end) of the lever main body 11F. The cutout 56 includes a circular hole 561 and a rectangular hole 562 communicating with the circular hole 561. The rectangular hole 562 extends in the longitudinal direction and is open at the other end. The edge of the other end 120F of the lever body 11F is a first edge 30F.

As explained above, in the fourth reference example, since the rotational moment applied to the other end 120F of the lever body 11F is applied to the notch 56, the knob part 12 is further prevented from coming off from the lever body 11F. , and the bending rigidity of the lever body 11F is improved.
