The engagement protrusion is not allowed to contact.

  A spring 22 (compression coil spring) as an urging means constituting a moderation mechanism is spanned between the base 12 and the moderation pin 20, and the spring 22 applies the moderation pin 20 to the upper side and the working direction. Thus, the upper surface of the action projection 20A of the moderation pin 20 is brought into contact with the moderation surface 18 of the knob 16 (see FIG. 3). For this reason, the spring 22 biases the knob 16 through the moderation pin 20 in the direction from the convex portion 18B side of the moderation surface 18 toward the concave portion 18A.

  The base 12 (which may be the support base 14 or the knob 16) is provided with a shift sensor (not shown) as a shift detection means. The shift sensor detects the rotational position of the knob 16 and shifts the knob 16. Detect position. The shift sensor is electrically connected to a vehicle control device (not shown), and an automatic transmission (not shown) of the vehicle is electrically connected to the control device. By being changed, the automatic transmission is controlled by the control device so that the automatic transmission corresponds to the shift position of the knob 16 (“P” range (parking range), “R” range (reverse range), “N” range (neutral)). Range) and “D” range (drive range)).

  An engine start / stop switch (not shown) as an operation unit is electrically connected to the control device, and a vehicle engine (not shown) is electrically connected. When the engine is stopped and the engine start / stop switch is operated by the occupant, the engine is started. On the other hand, when the engine is started and the engine start / stop switch is operated by a passenger, the engine is stopped.

  The base 12 is provided with an autocorrect mechanism 24 as rotating means.

  The autocorrect mechanism 24 is provided with a motor (not shown) as drive means. The motor is fixed to the base 12 and is electrically connected to the control device. The motor is mechanically connected to a transmission mechanism (deceleration mechanism, not shown), and the transmission mechanism is supported by the base 12.

  A substantially cylindrical rotor cam 26 as a rotating member is rotatably supported on the base 12 below the knob 16, and the rotor cam 26 is arranged at a specified rotational position on the same axis as the knob 16. . A transmission mechanism is mechanically connected to the rotor cam 26, and when the motor is driven, the rotor cam 26 is decelerated and rotated through the transmission mechanism.

  The rotor cam 26 is integrally provided with a release plate constituting a release means and a rotating plate 26A having a curved rectangular plate shape as a rotating unit, and the rotating plate 26A protrudes upward. The rotating plate 26A is curved along the peripheral wall of the rotor cam 26, and the end surface on the other side of the rotating plate 26A is curved in a convex shape in the thickness direction. The rotating plate 26A is disposed in the knob 16 and is disposed in the vicinity of one direction side of the rotating projection 20B of the moderation pin 20. The rotating plate 26A is spaced apart from the engaging projection of the knob 16 in one direction side. As a result, even when the knob 16 is rotated between the “P” position and the “D” position, the engagement protrusion of the knob 16 cannot be contacted.

  As shown in FIG. 1, the base 12 (which may be the support base 14 or the knob 16) is provided with a rotation sensor 28 (for example, a Hall IC) as rotation detection means, and the rotation sensor 28 is a rotational position of the rotor cam 26. And is electrically connected to the control device.

  Next, the operation of this embodiment will be described.

  In the shift device 10 having the above-described configuration, the knob 16 is rotated, whereby the shift position of the knob 16 is changed to the “P” position, the “R” position, the “N” position, and the “D” position. Further, when the knob 16 is rotated, every time the shift position of the knob 16 is changed, the action protrusion 20A of the moderation pin 20 is brought into contact with the moderation surface 18 of the knob 16 by the biasing force of the spring 22. The state is moved between the recesses 18 </ b> A while getting over the protrusions 18 </ b> B on the moderation surface 18, and a sense of moderation is applied to the rotation operation of the knob 16.

  By the way, when the knob 16 is disposed at a shift position other than the “P” position (“R” position, “N” position or “D” position, for example, “D” position), the shift position of the knob 16 is “ When the engine is stopped by operating the engine start / stop switch when the shift sensor detects that the position is other than the “P” position), the shift range of the automatic transmission is set to “P” under the control of the control device. Changed to range. Further, when the shift range of the automatic transmission is changed to the “P” range, the knob 16 is rotated to a shift position other than the “P” position after the engine start / stop switch is operated to start the engine. Until the shift sensor detects that the shift position of the knob 16 has been changed to a position other than the “P” position. For this reason, whenever the engine start / stop switch is operated, the shift range of the automatic transmission is set to the “P” range.

  When the knob 16 is arranged at a shift position other than the “P” position, when the engine start / stop switch is operated (a predetermined opportunity when the engine is stopped and / or started), In the auto correct mechanism 24, the motor is reversely driven by the control of the control device, whereby the rotor cam 26 is rotated in the other direction via the transmission mechanism. For this reason, after the rotating plate 26A of the rotor cam 26 is brought into contact with the engaging protrusion of the knob 16, the knob 16 is rotated in the other direction by pressing the engaging protrusion of the knob 16 in the other direction. Knob 16 is rotated to the “P” position. Thereby, when the engine start / stop switch is operated, the knob 16 can be arranged (returned) to the “P” position, and the shift position of the knob 16 can be matched with the shift range of the automatic transmission.

  When the knob 16 is rotated to the “P” position (when the shift sensor detects that the shift position of the knob 16 is the “P” position), the motor is positively driven by the control of the control device. Thus, the rotor cam 26 is rotated in one direction via the transmission mechanism. Further, when the rotor cam 26 is rotated to the specified rotation position (when the rotation sensor 28 detects that the rotation position of the rotor cam 26 is the specified rotation position), the positive drive of the motor is stopped under the control of the control device. Thus, the rotation of the rotor cam 26 in one direction is stopped. For this reason, even if the knob 16 is rotated from the “P” position to the “D” position by separating the rotary plate 26A of the rotor cam 26 from the engagement protrusion of the knob 16 in one direction, the engagement of the knob 16 is achieved. The protrusions are prevented from coming into contact with the rotating plate 26A of the rotor cam 26.

  As described above, when the rotor cam 26 is rotated in the other direction, before the rotating plate 26A of the rotor cam 26 presses the engaging protrusion of the knob 16 in the other direction, as shown in FIGS. The rotating plate 26A is brought into contact with the rotating protrusion 20B of the moderation pin 20. Further, as shown in FIG. 4, the rotating plate 26 </ b> A presses the rotating protrusion 20 </ b> B, and the moderation pin 20 is rotated in the releasing direction against the urging force of the spring 22. The tip end surface of 26A reaches the inner peripheral surface of the rotating projection 20B, and the action projection 20A of the moderation pin 20 is moved (revolved) from the moderation surface 18 of the knob 16 to the release surface 16A (to the knob 16 of the action projection 20A). Is changed from the moderation surface 18 to the release surface 16A).

  Thereafter, when the rotary plate 26A of the rotor cam 26 presses the engaging protrusion of the knob 16 in the other direction, and the knob 16 is rotated from the shift position other than the “P” position to the “P” position, the rotary plate By moving the inner peripheral surface of the rotation protrusion 20B on the tip surface of 26A, the state where the moderation pin 20 is rotated in the release direction is maintained, and the action protrusion 20A of the moderation pin 20 is applied to the release surface 16A of the knob 16. The moved state is maintained.

  Next, when the rotor cam 26 is rotated in one direction, the rotating protrusion 20B passes through the tip surface of the rotating plate 26A. For this reason, before the rotor cam 26 is rotated to the specified rotational position, the moderation pin 20 is rotated in the operation direction by the biasing force of the spring 22, so that the operation protrusion 20 </ b> A of the moderation pin 20 is released from the release surface 16 </ b> A of the knob 16. To the moderation surface 18 (revolved).

  Here, as described above, when the knob 16 is rotated from the shift position other than the “P” position to the “P” position by the rotor cam 26, the rotating plate 26A of the rotor cam 26 rotates the moderation pin 20 in the release direction. Thus, the action projection 20A of the moderation pin 20 is moved from the moderation surface 18 of the knob 16 to the release surface 16A (contact of the action projection 20A with the moderation surface 18 is released), so The release surface 16A is moved while being in contact with the release surface 16A by the urging force. For this reason, it is suppressed that abnormal noise (passing noise) due to getting over the convex portion 18B between the concave portions 18A in the moderation surface 18 in a state where the acting projection 20A is in contact with the moderation surface 18 by the urging force of the spring 22 is suppressed. it can.

  Further, as described above, the rotating plate 26A of the rotor cam 26 rotates the moderation pin 20 in the release direction, and the action protrusion 20A of the moderation pin 20 is moved from the moderation surface 18 of the knob 16 to the release surface 16A. For this reason, the contact with the moderation surface 18 of the action protrusion 20A can be easily released.

  A rotating plate 26 </ b> A is provided on the rotor cam 26. For this reason, the rotating plate 26A can be easily rotated by the rotation of the rotor cam 26, and the rotating plate 26A can be easily installed.

  Further, the operation protrusion 20 </ b> A of the moderation pin 20 is brought into contact with the moderation surface 18 of the knob 16 in the axial direction of the knob 16. For this reason, the shift device 10 can be reduced in size in the radial direction of the knob 16.

  In this embodiment, when the engine is stopped by operating the engine start / stop switch while the knob 16 is disposed at a shift position other than the “P” position, the shift range of the automatic transmission is “ The shift position of the knob 16 may be changed to the “P” position after being changed to the “P” range, and the shift range of the automatic transmission is changed to “P” after the shift position of the knob 16 is changed to the “P” position. It may be changed to the “P” range.

  In the present embodiment, the autocorrect mechanism 24 changes the shift position of the knob 16 to the “P” position. However, the autocorrect mechanism 24 may change the shift position of the knob 16 to a shift position other than the “P” position (eg, “R” position, “N” position, and “D” position).

  Further, in the present embodiment, one moderation surface 18 and one moderation pin 20 are provided. However, a plurality of moderation surfaces 18 and moderation pins 20 may be provided, and in this case, a plurality of rotating plates 26A may be provided.

  In the present embodiment, the moderation pin 20 is provided on the base 12 side, and the moderation surface 18 is provided on the knob 16 side. However, the moderation pin 20 may be provided on the knob 16 side and the moderation surface 18 may be provided on the base 12 side.

  Further, in this embodiment, the spring 22 biases the moderation pin 20. However, the spring 22 may bias the moderation surface 18.

  In the present embodiment, the shift device 10 is a by-wire type. However, the shift device 10 may be other than the by-wire type (for example, a mechanical cable type).

  Furthermore, in this embodiment, the shift apparatus 10 was installed in the instrument panel. However, you may install the shift apparatus 10 in the floor part of a vehicle compartment, or a column cover.
