The second connecting portion 24 is movable and is allowed to move in the vertical direction. When the lever 18 is rotated from the “H” position to the “B” position (rear side), the second connecting portion 24 is rotated to the front side and the second link 30 is rotated to the front side. (See Figure 3). Further, when the lever 18 is rotated from the “H” position to the “N” position (left side), the first link 28 is moved upward and the second link 30 is moved upward (FIG. 2). Further, when the lever 18 is rotated from the “N” position to the “R” position (front side) and the “D” position (rear side), the second link 30 is moved upward, respectively.

  On the right side of the plate 12, a sensor board 34 as a detecting means is fixed on the right side of the link mechanism 26. The sensor board 34 is arranged vertically in the left-right direction, and is connected to the magnet 32 on the right side of the magnet 32. They are facing each other. The sensor substrate 34 is capable of detecting the magnetic force generated by the magnet 32, whereby the vertical position and the front-back position of the magnet 32 are detected.

  Next, the operation of this embodiment will be described.

  In the shift lever device 10 having the above configuration, when the lever 18 is rotated from the “H” position to the “B” position (rear side), the first connecting portion 22 of the lever 18 is rotated around the central axis line. As a result, the first link 28 is not moved, the second connecting portion 24 of the lever 18 is rotated forward, and the second link 30 is rotated forward (see FIG. 3). Further, when the lever 18 is rotated from the “H” position to the “N” position (left side), the first link portion 22 is rotated upward, so that the first link 28 moves upward. Then, the second link 30 is moved upward (see FIG. 2). Further, when the lever 18 is rotated from the “N” position to the “R” position (front side) and the “D” position (rear side), the first connecting portion 22 is rotated around the central axis line, The state where the first link 28 and the second link 30 are moved upward is maintained, and the second connecting portion 24 is rotated to the rear side and the front side, respectively, so that the second link 30 is moved to the rear side and the front side. It is rotated.

  Further, the magnet 32 is moved integrally with the second link 30 in the vertical direction and is rotated in the front-back direction. Therefore, when the sensor substrate 34 detects the magnetic force generated by the magnet 32, the vertical position and the longitudinal position of the magnet 32 are detected, and the shift position of the lever 18 is detected.

  Here, when the lever 18 is rotated in the front-rear direction, the front wall and the rear wall of the restricting portion 14A restrict the movement of the first link 28 in the front-rear direction, and the second connecting portion 24 of the lever 18 is included. The (second connecting ball 24A) rotates the second link 30 in the front-rear direction, so that the amount of rotation of the second link 30 in the front-rear direction is larger than the amount of rotation of the first link 28 in the front-rear direction.

  Further, the first connecting ball 22A of the first connecting portion 22 of the lever 18 (center axis of rotation of the lever 18 in the front-rear direction) and the connecting shaft 30A of the second link 30 (rotation of the second link 30 in the front-rear direction). The central axis) is spaced apart from each other, and the radial distance of the magnet 32 with respect to the connecting shaft 30A of the second link 30 in the radial direction of rotation of the second link 30 is equal to the second connecting portion 24 of the lever 18 with respect to the connecting shaft 30A of the second link 30. The distance between the two links 30 is increased in comparison with the radial direction distance (maximum distance).

  Therefore, when the lever 18 is rotated in the front-rear direction, the amount of rotation of the magnet 32 in the front-rear direction is amplified with respect to the amount of rotation of the second connecting portion 24 of the lever 18 in the front-rear direction. Accordingly, even if the amount of rotation of the lever 18 between the shift positions in the front-rear direction is reduced, the amount of rotation of the magnet 32 in the front-rear direction due to the rotation of the lever 18 between the shift positions in the front-rear direction can be increased. The 18 shift positions can be accurately detected in the front-rear direction. Therefore, the shift position of the lever 18 can be accurately detected in the front-rear direction without providing the magnet 32 in a portion separated from the center of rotation of the lever 18 in the front-rear direction, and it is necessary to increase the vertical dimension of the lever 18. It can be eliminated, and the shift lever device 10 can be downsized in the vertical direction.

  Further, a first connecting portion 22 is provided on the rotation restricting portion 20A of the lever 18 (on the axis of rotation in the front-back direction). Therefore, unlike the case where the first connecting portion 22 is provided above or below the rotation restricting portion 20A of the lever 18, when the lever 18 is rotated in the left-right direction, the left and right sides of the first connecting portion 22 are not changed. The amount of movement in the direction can be reduced, and the contact between the first connecting portion 22 (first connecting ball 22A) and the first link 28 (first connecting hole 28B) can be maintained.

  Further, the displacement of the first link 28 from the plate 12 to the right side is locked by the right wall of the restricting portion 14A of the cover 14, and the displacement of the extension plate 30B of the second link 30 from the plate 12 to the right side is locked. It is locked by the plate 16. Therefore, the rattling of the first link 28 and the second link 30 in the left-right direction can be suppressed.

  Further, the displacement of the first link 28 and the second link 30 from the plate 12 to the right side is at the upper part (the position of the cover 14) and the lower part (the position of the locking plate 16) of the entire first link 28 and the second link 30. It is locked. Therefore, the rattling of the first link 28 and the second link 30 in the left-right direction can be effectively suppressed.

  Moreover, the displacement of the upper end portion of the second link 30 from the plate 12 to the right side is locked by the lower portion of the first link 28. Therefore, the displacement of the second link 30 to the right can be locked with a simple configuration.

  In the present embodiment, the rotation amount (rotation stroke or rotation angle) of the magnet 32 about the connecting shaft 30A is the rotation amount of the lever 18 about the ball shaft 20 (rotation stroke or rotation angle). It may be amplified with respect to the angle).

  Further, in the present embodiment, when the lever 18 is rotated in the front-rear direction, the first link 28 is not rotated in the front-rear direction, so that the second link 30 rotates in the front-rear direction (rotation stroke or rotation stroke or The rotation angle and the like) are increased with respect to the rotation amount (rotation stroke or rotation angle) of the first link 28 in the front-rear direction. However, when the lever 18 is rotated in the front-rear direction, the amount of rotation of the second link 30 in the front-rear direction (a rotation stroke, a rotation angle, or the like) is the amount of rotation of the first link 28 in the front-rear direction (rotation). The first link 28 may be rotated in the front-rear direction in a state of being increased with respect to the dynamic stroke or the rotation angle).

  Further, in the present embodiment, the connecting hole 28A is provided in the first link 28, and the connecting shaft 30A is provided in the second link 30. However, the connecting shaft 30A may be provided in the first link 28 and the connecting hole 28A may be provided in the second link 30.
