When the knob 18 is arranged at each shift position, the first operation magnet 20A is slightly shifted in the first positive direction A1 (for example, the rotation angle is 2°) from the rotation position where the first operation magnet 20A faces the first fixed magnet 16A above. By displacing the shifted rotational position and applying a rotational force (biasing force) in the first reverse direction B1 to the first gear 22A, the knob 18 receives a rotational force (biasing force) in the reverse direction B from the first gear 22A. biasing force) is applied. Further, the second operating magnet 20B is arranged at a rotational position slightly shifted in the second opposite direction B2 (for example, the rotational angle is 2°) from the rotational position facing the second fixed magnet 16B on the upper side, and the second gear By applying a rotational force (biasing force) in the second positive direction A2 to 22B, a rotational force (biasing force) in the positive direction A is applied to the knob 18 from the second gear 22B. Moreover, since the rotational force acting on the first gear 22A in the first reverse direction B1 and the rotational force acting on the second gear 22B in the second forward direction A2 are set to the same magnitude, the knob The rotational force in the reverse direction B acting on the knob 18 from the first gear 22A and the rotational force in the forward direction A acting on the knob 18 from the second gear 22B are set to the same magnitude, so that the knob 18 rotates in each direction. It is held in the shift position.

Next, the operation of this embodiment will be described.

In the shift device 10 configured as described above, the shift position of the knob 18 is changed by rotating the knob 18 . In the detent mechanism 14, the knob 18 is rotated in the forward direction A, the first gear 22A and the second gear 22B are rotated in the first forward direction A1 and the second forward direction A2, respectively, and the knob 18 is rotated in the opposite direction. Rotating in the direction B causes the first gear 22A and the second gear 22B to rotate in the first reverse direction B1 and the second reverse direction B2, respectively.

When the knob 18 is rotated in the positive direction A to change the shift position of the knob 18, the first gear 22A (see F1 in FIG. 3) is positioned so that the upper end of the first operation magnet 20A is positioned at the upper side of the plate 12. The first fixed magnet 16A rotates while being attracted to the lower end thereof, and a rotational resistance force in the first reverse direction B1 acts on the first gear 22A. Then, the upper end of the first operating magnet 20A is rotated while being attracted to the lower end of the first fixed magnet 16A on the first positive direction A1 side of the first fixed magnet 16A, and the first gear 22A rotates in the first positive direction A1. is applied, the rotation resistance force in the first opposite direction B1 is applied.

In addition, the rotational direction component of the first gear 22A of the attractive force between the upper end of the first operating magnet 20A and the lower end of the first fixed magnet 16A is opposite to the rotating direction of the first gear 22A at the upper end of the first operating magnet 20A. When the side end passes through the rotational direction side end of the first gear 22A at the bottom end of the first fixed magnet 16A, and when the first gear 22A at the top end of the first operating magnet 20A, the side end in the rotational direction It becomes maximum when passing the end opposite to the rotation direction of the gear 22A. Therefore, when the knob 18 is rotated in the positive direction A to change the shift position of the knob 18, the rotational resistance acting on the first gear 22A gradually increases and then gradually decreases, Then, the rotational assist force acting on the first gear 22A is gradually increased and then gradually decreased, and finally the rotational resistance force acting on the first gear 22A is gradually increased.

Further, when the knob 18 is rotated in the forward direction A to change the shift position of the knob 18, the second gear 22B (see F2 in FIG. 3) moves the plate 12 with the upper end of the second operation magnet 20B upward. The second gear 22B is rotated while being attracted to the lower end of the second fixed magnet 16B, and after the rotation assist force in the second positive direction A2 is first applied to the second gear 22B, the rotation resistance force in the second reverse direction B2 is applied. be. Then, the upper end of the second operating magnet 20B is rotated while being attracted to the lower end of the second fixed magnet 16B on the second positive direction A2 side of the second fixed magnet 16B, and is rotated in the second positive direction A2 by the second gear 22B. of rotation assistance force is applied.

The second gear 22B rotation circumferential direction component of the attractive force between the upper end of the second operating magnet 20B and the lower end of the second fixed magnet 16B is the same as the upper end of the first operating magnet 20A and the lower end of the first fixed magnet 16A. It is the same as the first gear 22A rotation circumferential direction component of the attraction force between . Therefore, when the knob 18 is rotated in the positive direction A to change the shift position of the knob 18, the rotation assisting force first acting on the second gear 22B is gradually reduced, The rotation resistance acting on 22B is gradually increased and then gradually decreased, and the rotation assisting force acting on the second gear 22B is gradually increased and then gradually decreased.

As a result, when the knob 18 is rotated in the forward direction A and the shift position of the knob 18 is changed, the torque from the first gear 22A and the second gear 22B is applied to the knob 18 (see F in FIG. 3). is acted on the knob 18, the rotation resistance force in the reverse direction B acting on the knob 18 is gradually increased and then gradually decreased, and the rotation assisting force in the forward direction A acting on the knob 18 is gradually increased It is gradually decreased after being increased.

On the other hand, when the knob 18 is rotated in the reverse direction B to change the shift position of the knob 18, the rotational force acting on the first gear 22A is the same as when the knob 18 is rotated in the forward direction A. The rotational force acting on the second gear 22B is the same as the rotational force acting on the second gear 22B (see F2 in FIG. 3), and the rotational force acting on the second gear 22B is applied to the first gear 22A when the knob 18 is rotated in the forward direction A. is similar to the rotational force acting on (see F1 in FIG. 3).

As a result, when the knob 18 is rotated in the reverse direction B and the shift position of the knob 18 is changed, the torque from the first gear 22A and the second gear 22B is applied to the knob 18 (see F in FIG. 3). is acted on the knob 18, the rotation resistance force in the forward direction A acting on the knob 18 gradually increases and then gradually decreases, and the rotation assisting force in the reverse direction B acting on the knob 18 gradually increases It is gradually decreased after being increased.

As described above, when the knob 18 is rotated in the forward direction A to change the shift position of the knob 18, and when the knob 18 is rotated in the reverse direction B to change the shift position of the knob 18, the knob A biasing force toward the shift position is applied to the knob 18, and a click feeling is applied to the operation of changing the shift position of the knob 18. - 特許庁
