The magnet 26 can be rotated in one direction and the other direction integrally with the holder 22 and can be tilted in the tilting direction and the restoring direction, so that the direction of the magnetic flux generated by the magnet 26 can be changed. Has been.

In the case lower 18B, a rectangular plate-shaped sensor substrate 28 (see FIGS. 4, 5A, and 5B) as a detection mechanism is fixed, and the sensor substrate 28 is arranged vertically in the vertical direction. A plurality of (in this embodiment, three) magnetic sensors 28A (eg, 3D Hall sensors) serving as detection parts are provided in the center of the sensor substrate 28. The plurality of magnetic sensors 28A are arranged on the sensor substrate 28. They are different from each other (in this embodiment, one is arranged on the upper surface of the sensor substrate 28 and two are arranged on the lower surface of the sensor substrate 28).

When the magnet 26 is rotated in one direction and the other direction, the magnetic flux H generated on the lower surface of the magnet 26 is rotated in one direction and the other direction integrally with the magnet 26, and the longitudinal direction of the magnetic flux H in the magnetic sensor 28 </ b> A. The component and the horizontal component change. For this reason, when the magnetic sensor 28A detects the front-rear direction component and the left-right direction component of the magnetic flux H, the rotational position of the magnet 26 in one direction and the other direction is detected. When the magnet 26 is tilted in the tilting direction and the restoring direction, the magnetic flux H generated by the lower surface of the magnet 26 is tilted in the tilting direction and the restoring direction integrally with the magnet 26, and the vertical direction of the magnetic flux H in the magnetic sensor 28 </ b> A. Ingredients change. For this reason, when the magnetic sensor 28A detects the vertical component of the magnetic flux H, the tilt position of the magnet 26 in the tilt direction and the restoring direction is detected.

Next, the operation of this embodiment will be described.

In the shift device 10 having the above configuration, the knob 14 is rotated in one direction and the other direction and displaced in the vertical direction, and the shift position of the knob 14 is changed.

Here, when the knob 14 is rotated in one direction and the other direction, the holder 14 and the magnet 26 are rotated in one direction and the other direction by the knob 14, and when the knob 14 is displaced in the vertical direction. The holder 22 and the magnet 26 are tilted in the tilting direction and the restoring direction by the knob 14. Further, the magnetic sensor 28A of the sensor substrate 28 detects the rotation position in one direction and the other direction of the magnet 26 and the tilt position in the tilt direction and the restoring direction, thereby rotating the knob 14 in one direction and the other direction. The position and the displacement position in the vertical direction are detected, and the shift position of the knob 14 is detected. For this reason, even when the knob 14 is rotated in one direction and the other direction and displaced in the vertical direction, the shift position of the knob 14 can be detected.

Further, the connecting ball 24A of the holder 22 (joint 24) on the magnet 26 side is fitted in the connecting hole 16A of the knob 14 (arm 16) in the circumferential direction and the vertical direction of the knob 14 and the holder 22. Therefore, when the knob 14 is rotated in one direction and the other direction, the magnet 26 can be rotated in one direction and the other direction, and when the knob 14 is displaced in the vertical direction, the magnet 26 is tilted and restored. Can tilt in the direction.

Further, the support frame 20 of the case 18 supports the holder 22 and the magnet 26 so that the holder 22 and the magnet 26 can be rotated in one direction and the other direction and can be tilted in the tilting direction and the restoring direction. For this reason, the knob 14 is rotated in one direction and the other direction so that the magnet 26 can be properly rotated in one direction and the other direction, and the knob 14 is displaced in the vertical direction so that the magnet 26 is appropriately tilted and restored. Can tilt.

In addition, the knob 14 is rotated in one direction and the other direction at the upper and lower displacement positions, and the holder 22 and the magnet 26 are rotated in one direction and the other direction at the tilt position between the restoring direction side and the tilting direction side. Is done. Therefore, even when the knob 14 is rotated in one direction and the other direction at the displacement position between the upper side and the lower side, the magnetic sensor 28A of the sensor substrate 28 is rotated in one direction and the other direction of the magnet 26 and the tilt direction. And the shift position of the knob 14 can be detected by detecting the tilt position in the restoring direction.

Further, the knob 14 is rotated in one direction and the other direction at the displacement positions of the upper side and the lower side. For this reason, unlike the case where the knob 14 is rotated in one direction and the other direction at one vertical displacement position, the number of shift positions arranged in the rotation direction in one direction and the other direction of the knob 14 is reduced. The amount of rotation of the knob 14 in one direction and the other direction can be reduced.

Also, the joint 24 of the holder 22 extends upward, and the connection sphere 24A of the joint 24 and the connection hole 16A of the knob 14 (arm 16) (the center of the connection sphere 24A and the connection hole 16A) are magnets 26 (of the magnet 26). It is arranged above the upper end, the center and the lower end) (on the side opposite to the sensor substrate 28 of the magnet 26). For this reason, it is possible to suppress the joint 24 and the arm 16 from interfering with the sensor substrate 28 when the holder 22 and the magnet 26 are tilted in the tilting direction. Thereby, the magnet 26 and the sensor substrate 28 can be arranged close to each other, the detection accuracy of the rotation position and the tilt position of the magnet 26 by the magnetic sensor 28A of the sensor substrate 28 can be increased, and the detection accuracy of the shift position of the knob 14 can be increased. Can be high.

Furthermore, a pair of magnetic poles are magnetized on the lower surface of the magnet 26 (the surface on the sensor substrate 28 side). Therefore, the magnet 26 can effectively generate the magnetic flux H on the lower side (the sensor substrate 28 side), and the detection accuracy of the rotational position and the tilt position of the magnet 26 by the magnetic sensor 28A of the sensor substrate 28 is effectively improved. The detection accuracy of the shift position of the knob 14 can be effectively increased.

In addition, the tilting center O of the holder 22 and the magnet 26 (the center of curvature of the fitting surface 22A of the holder 22, see FIG. 5A) is arranged above the center of the magnet 26. For this reason, the tilting amount of the magnet 26 due to the tilting of the holder 22 and the magnet 26 can be increased, the detection accuracy of the tilting position of the magnet 26 by the magnetic sensor 28A of the sensor substrate 28 can be effectively increased, and the shift position of the knob 14 can be adjusted. The detection accuracy can be effectively increased.

Further, a plurality of magnetic sensors 28A are provided on the sensor substrate 28, and the arrangement of the plurality of magnetic sensors 28A is different from each other. Therefore, by detecting the magnetic flux H generated by the magnet 26 at a position where the plurality of magnetic sensors 28A are different from each other, the detection accuracy of the rotational position and tilting position of the magnet 26 can be effectively increased, and the shift position of the knob 14 is increased. The detection accuracy can be effectively increased.

In the present embodiment, a pair of magnetic poles (N pole and S pole) are magnetized on the lower surface of the magnet 26. However, a plurality of pairs of magnetic poles (N pole and S pole) may be magnetized on the lower surface of the magnet 26.

Furthermore, in this embodiment, the tilting center O of the holder 22 and the magnet 26 is arranged above the center of the magnet 26. However, the tilt center O of the holder 22 and the magnet 26 may be arranged above the upper end of the magnet 26. In addition, the tilt center O of the holder 22 and the magnet 26 may coincide with the center of the magnet 26, and the tilt center O of the holder 22 and the magnet 26 may be disposed below the center of the magnet 26.

In this embodiment, the shift device 10 is installed on the console. However, you may install the shift apparatus 10 in an instrument panel or a column cover.
