  On the upper wall of the rear plate 12B, a metal columnar shaft 14 (see FIG. 4B) as a second support is provided by insert molding. The shaft 14 has an axial direction in the front-rear direction. It is made parallel and extends forward. The shaft 14 passes through the bearing 12C in the front-rear direction, and the central axis of the shaft 14 passes through the center of the bearing 12C (the center of curvature of the inner peripheral surface).

  On the upper wall of the front plate 12A, a metal cylindrical collar 16 (see FIG. 4B) as a second support portion is provided by insert molding, and the inside of the collar 16 communicates with the bearing 12C. Has been. In the collar 16, the shaft 14 is fitted coaxially, and the collar 16 supports the shaft 14.

  A substantially rectangular plate-shaped housing 18 as a covering member is assembled on the upper side of the plate 12, and the housing 18 covers the upper side of the plate 12.

  In the plate 12, there is provided a long, substantially columnar lever 20 (see FIGS. 2A and 2B) made of resin as a shift body. A spherical ball axis 20A (see FIGS. 3A and 3B and FIG. 4A) is formed. A limiting hole 22 having a substantially elliptical cross section is formed in the spherical axis 20A, and the limiting hole 22 penetrates the spherical axis 20A in the front-rear direction. The left surface and the right surface of the restriction hole 22 are flat surfaces in the left-right direction, and the upper surface and the lower surface of the restriction hole 22 are curved surfaces having a semicircular cross section. The center is coincident with the center of the spherical axis 20A (the center of curvature of the peripheral surface (outer peripheral surface)).

The center of the axis) coincides with the center of the restriction hole 22. The inner peripheral portion of the ring 24 is curved in a convex shape inward in the radial direction, and the axial dimension is reduced as it goes inward in the radial direction. The radial dimension in the ring 24 is the width direction of the restriction hole 22 ( It is consistent with the dimension (front-rear direction).

  The shaft 14 of the plate 12 is coaxially inserted in the restriction hole 22, and the shaft 14 is fitted in the restriction hole 22 in the left-right direction so that the lever 20 (spherical axis 20 </ b> A) is rotated around the axis (around the axis). The rotation is limited. The shaft 14 is coaxially fitted in the ring 24, and the shaft 14 supports the lever 20 (including the ring 24). For this reason, the ring 24 is tilted in the front-rear direction with respect to the shaft 14 so that the lever 20 can be rotated in the front-rear direction (shift direction, first direction), and the ring 24 is rotated around the axis of the shaft 14. Thus, the lever 20 is rotatable in the left-right direction (select direction, second direction). Further, when the ring 24 is tilted in the front-rear direction with respect to the shaft 14, the fitting of the inner peripheral portion of the ring 24 to the outer peripheral surface of the shaft 14 is maintained.

  The peripheral surface of the upper portion of the spherical shaft 20A is covered with a resin-made substantially hemispherical wall-like sheet 26 (see FIGS. 2A and 2B). And open to the bottom. The inner peripheral surface of the sheet 26 is fitted to the peripheral surface of the spherical shaft 20A, and the sheet 26 is rotatable integrally with the spherical shaft 20A.

For this reason, the spherical shaft 20A (including the seat 26) is rotated with respect to the bearing 12C, so that the lever 20 is rotatable in the front-rear direction and the left-right direction.

  The upper part of the lever 20 above the spherical axis 20A is pivotably penetrated through the housing 18 and extends to the upper side of the housing 18. The lever 20 has a vehicle occupant (for example, a driver) at the upper end. It can be rotated in the front-rear direction and the left-right direction. The lever 20 is disposed at an “H” position (home position) as a shift position (predetermined shift position), and the lever 20 is rotated from the “H” position to the rear side, and “ It is arranged at the “B” position (brake position) and is rotated from the “H” position to the right side (or left side) to be arranged at the “N” position (neutral position) as the shift position. Further, the lever 20 is rotated from the “N” position to the front side and is disposed at the “R” position (reverse position) as the shift position, and is also operated to rotate from the “N” position to the rear side. , It is arranged at the “D” position (drive position) as the shift position.

  Further, when the lever 20 is rotated to the front side, the upper surface front end and the lower surface rear end of the restriction hole 22 in the spherical shaft 20A are brought into contact with the shaft 14 to rotate the lever 20 to the front side. Operation is restricted. On the other hand, when the lever 20 is rotated to the rear side, the upper surface rear end and the lower surface front end of the restriction hole 22 in the spherical shaft 20A are brought into contact with the shaft 14 so that the lever 20 is moved rearward. The turning operation is restricted.

  A substantially rectangular flat plate-like detection plate 28 (see FIGS. 2A and 2B, FIG. 6) is integrally provided on the lower portion of the lever 20 from the spherical axis 20A. The detection plate 28 is disposed substantially perpendicular to the vertical direction, and extends from the lever 20 to both sides in the front-rear direction and both sides in the left-right direction. The lower surface of the detection plate 28 is a flat fixed surface 28A in each of the left and front portions, the left and rear portions, the right and front portions, and the right and rear portions, and a plurality of fixed surfaces. The surfaces 28A have different inclination angles with respect to the vertical direction. A metal plate 28B made of metal as a detected portion is fixed to each fixed surface 28A, and the plurality of metal plates 28B have different inclination angles with respect to the vertical direction. The detection plate 28 is rotatable integrally with the lever 20, and when the lever 20 is rotated to the front side and the rear side, the detection plate 28 is rotated to the rear side and the front side, respectively. When the lever 20 is rotated to the left and right, the detection plate 28 is rotated to the right and left, respectively.

  Near the lower side of the detection plate 28, a sensor substrate 30 (see FIGS. 2A and 2B and FIG. 6) as a substantially rectangular flat plate as a detection body is arranged. 12 is fixed. The sensor substrate 30 is arranged vertically in the up-down direction, and a lower portion of the sensor board 30 from the detection plate 28 is rotatably penetrated.

Each sensor 30A is opposed to each metal plate 28B in the vertical direction, and in each set of metal plate 28B and sensor 30A (metal plate 28B and sensor 30A opposed in each vertical direction), sensor 30A is metal plate 28B. The tilt angle with respect to the sensor 30A can be detected.

  When the lever 20 is rotated in the front-rear direction and the left-right direction and the shift position of the lever 20 is changed, the detection plate 28 is rotated in the front-rear direction and the left-right direction, and each set of the metal plate 28B and the sensor. In 30A, the inclination angle of the metal plate 28B with respect to the sensor 30A is changed. For this reason, in each set of the metal plate 28B and the sensor 30A, the sensor 30A detects the tilt angle of the metal plate 28B with respect to the sensor 30A, and the sensor substrate 30 detects the rotational position of the detection plate 28. The rotation position of 20 is detected, and the shift position of the lever 20 is detected.

  The sensor board 30 is electrically connected to a control device (not shown), and an automatic transmission (not shown) of the vehicle is electrically connected to the control device. By detecting the shift position, the shift range of the automatic transmission is changed to a shift range corresponding to the shift position of the lever 20 under the control of the control device. That is, when the lever 20 is disposed at the “B” position, the “N” position, the “R” position, and the “D” position, the shift range of the automatic transmission is set to the “B” range (brake range), respectively. The range is changed to “N” range (neutral range), “R” range (reverse range), and “D” range (drive range).

  An additional mechanism 32 is provided above the rear portion of the sensor substrate 30, and the additional mechanism 32 is electrically connected to the control device via the sensor substrate 30 by being electrically connected to the sensor substrate 30. Has been.

  A “P” switch 34 as a shift mechanism is provided on the left side of the additional mechanism 32, and the “P” switch 34 passes through the upper wall of the plate 12 and the housing 18 and is exposed to the upper side of the housing 18. Has been. The “P” switch 34 can be operated (pressed) by the passenger. When the “P” switch 34 is operated, the shift range of the automatic transmission is set to “P” under the control of the control device. The range (parking range) is changed.

  An indicator 36 as a display mechanism is provided on the right side portion of the additional mechanism 32, and the indicator 36 penetrates the upper wall of the plate 12 and the housing 18 and is exposed to the upper side of the housing 18. The indicator 36 is visible to the occupant from above, and the shift range of the automatic transmission is displayed upward on the indicator 36 under the control of the control device. For this reason, the occupant can recognize the shift range of the automatic transmission by the indicator 36.

  Next, the operation of this embodiment will be described.

  In the shift device 10 configured as described above, when the lever 20 is rotated in the front-rear direction and the left-right direction, and the shift position of the lever 20 is changed, the detection plate 28 of the lever 20 is rotated in the front-rear direction and the left-right direction. Is done. Further, the rotation position of the detection plate 28 (inclination angle of each metal plate 28B with respect to each sensor 30A) is detected by the sensor substrate 30 (each sensor 30A), whereby the rotation position of the lever 20 is detected, and the lever Twenty shift positions are detected.

  Here, the bearing 12C of the plate 12 supports the circumferential surface of the spherical shaft 20A of the lever 20 via the seat 26, so that the lever 20 can be rotated in the front-rear direction. Further, in the plate 12, the shaft 14 supports the collar 16, and the shaft 14 supports the ring 24 of the lever 20 so that the lever 20 can be rotated in the left-right direction. For this reason, the lever 20 can be supported not only by the bearing 12C so as to be able to rotate but also by the shaft 14 so that the lever 20 can be supported by the support shaft (the center of the bearing 12C and the center of the spherical shaft 20A). Can be suppressed. Thereby, the accuracy of the rotation position of the detection plate 28 by the rotation of the lever 20 can be increased, the accuracy of the rotation position of the detection plate 28 with respect to the shift position of the lever 20 can be increased, and the shift of the lever 20 by the sensor substrate 30 can be achieved. The position detection accuracy can be increased. Therefore, a mechanism (for example, a link mechanism) is provided that can reduce the amount of change in the rotation position of the detection plate 28 due to the change in the shift position of the lever 20 and amplifies the amount of rotation of the detection plate 28 due to the change in the shift position of the lever 20. The necessity can be eliminated, the configuration can be simplified, and the shift device 10 can be miniaturized.

  Further, the bearing 12C of the plate 12 supports the peripheral surface of the spherical shaft 20A of the lever 20 via the seat 26, so that the lever 20 can be rotated in the left-right direction. In addition, the shaft 14 of the plate 12 supports the ring 24 of the lever 20 so that the lever 20 can be rotated in the front-rear direction. Therefore, not only can the lever 20 be supported by the bearing 12C so as to be pivotable in the front-rear direction and the left-right direction, but also the lever 20 can be supported by the shaft 14 so as to be pivotable in the front-rear direction and the left-right direction. Can be further suppressed, and the detection accuracy of the shift position of the lever 20 by the sensor substrate 30 can be further increased.

  Moreover, the shaft 14 and collar 16 of the plate 12 and the ring 24 of the lever 20 are made of metal. Therefore, the backlash between the shaft 14 and the collar 16 and the backlash between the shaft 14 and the ring 24 due to thermal expansion (linear expansion) of the shaft 14, the collar 16 and the ring 24 can be suppressed, and the support backlash of the lever 20 is further suppressed. Thus, the detection accuracy of the shift position of the lever 20 by the sensor substrate 30 can be further increased.

  Further, the shaft 14 is fitted in the restriction hole 22 of the spherical axis 20A in the left-right direction, so that the rotation of the lever 20 (including the detection plate 28) in the vertical direction is restricted. For this reason, the accuracy of the rotation position of the detection plate 28 by the rotation of the lever 20 can be further increased, and the detection accuracy of the shift position of the lever 20 by the sensor substrate 30 can be further increased. In addition, the rotation of the lever 20 around the vertical direction can be limited by the shaft 14, and the rotation of the lever 20 around the vertical direction can be suppressed with a simple configuration.

  Furthermore, when the lever 20 is rotated in the front-rear direction, the front-rear direction both ends of the circumferential surface of the restriction hole 22 of the spherical shaft 20A are brought into contact with the shaft 14 so that the lever 20 is rotated in the front-rear direction. Is regulated. For this reason, the rotation of the lever 20 in the front-rear direction can be restricted by the shaft 14, and the rotation of the lever 20 in the front-rear direction can be restricted with a simple configuration.

  In addition, the detection plate 28 is disposed substantially perpendicular to the vertical direction, and the sensor substrate 30 is disposed perpendicular to the vertical direction. For this reason, the vertical dimension of the detection plate 28 and the sensor substrate 30 can be reduced, and the vertical dimension of the shift device 10 can be reduced. Thereby, the space below the shift apparatus 10 in a vehicle can be enlarged, and the freedom degree, such as routing of the wire harness of the vehicle in the said space, can be improved.

  Further, an additional mechanism 32 (“P” switch 34 and indicator 36) is provided on the sensor board 30 and is electrically connected to the sensor board 30. For this reason, it is not necessary to provide a circuit board for the additional mechanism 32 separately from the sensor board 30, and connection means (connector or wire harness) for electrically connecting the circuit board and the sensor board 30 can be eliminated. ) Can be eliminated and the cost can be reduced.

  In the present embodiment, the shaft 14, the collar 16 and the ring 24 are made of metal. However, at least one of the shaft 14, the collar 16, and the ring 24 may be made of resin. Moreover, when the ring 24 is made of resin, the ring 24 may be integrally formed with the spherical shaft 20A.

  Furthermore, in this embodiment, the supported portion of the lever 20 is a substantially spherical ball axis 20A. However, the supported portion of the lever 20 may be substantially cylindrical. In this case, for example, the axial direction of the supported portion of the lever 20 is set to the left-right direction, and the supported portion of the lever 20 is supported in the front-rear direction so as to be rotatable about the axis. Enable tilting.

  In this embodiment, the shift device 10 is a floor type and installed on the floor of the passenger compartment. However, the shift device 10 may be installed on an instrument panel or a steering column in the passenger compartment.
