A worm 48 is coaxially fixed to the output shaft of the motor 46, and the worm 48 is engaged with the outer periphery of the rotor cam 42. The motor 46 is electrically connected to the control device 24, and the worm 48 is rotated by the forward and reverse operations of the motor 46 under the control of the control device 24, so that the rotor cam 42 is moved in the forward direction. And rotated in the opposite direction.

The rotor cam 42 can be arranged at the first restriction position (see FIGS. 4A and 5A). When the rotor cam 42 is located at the first restricting position, the first abutment column 54A of the first lock bar 54 is first locked on the bottom surface (the outer surface in the radial direction of the rotor cam 42) of the first restricting hole 64 of the rotor cam 42. The first lock bar 54 is protruded outside the support cylinder 14 A of the plate upper 14 by being brought into contact with the urging force of the spring 56.

Not protruded.

The rotor cam 42 can be arranged at a second restriction position (see FIGS. 4B, 5B and 6A) on the opposite side of the first restriction position. When the rotor cam 42 is located at the second restriction position, the first contact column 54 A of the first lock bar 54 contacts the peripheral surface of the release hole 62 of the rotor cam 42 by the urging force of the first lock spring 56. Thus, the first lock bar 54 does not protrude outside the support cylinder 14A of the plate upper 14.

The first lock bar 54 starts moving the rotor cam 42 in the radial direction and the second lock bar 58 starts moving the rotor cam 42 in the radial direction at the same time. The end of the movement of the rotor cam 42 in the radial direction of the rotor cam 42 and the end of the movement of the second lock bar 58 in the radial direction of the rotor cam 42 are simultaneously performed.

The rotor cam 42 can be arranged at a release position (see FIG. 6B) on the opposite side of the second restriction position. When the rotor cam 42 is located at the release position, the first contact column 54A of the first lock bar 54 is brought into contact with the peripheral surface of the release hole 62 of the rotor cam 42 by the urging force of the first lock spring 56, The first lock bar 54 does not protrude outside the support cylinder 14A of the plate upper 14.

Further, the second contact column 58A of the second lock bar 58 is slid by the urging force of the second lock spring 60 against the forward side surface of the second restriction hole 66 of the rotor cam 42, and the second lock bar 58 is rotated by the rotor cam. 42 in the radial direction.

Next, the operation of the present embodiment will be described.

In the shift device 10 having the above configuration, the knob 28 is rotated, and the shift position of the knob 28 is changed. In addition, the first regulating protrusion 28A and the second regulating protrusion 28B of the knob 28 abut on the second regulating surface 14D of the regulating column 14B of the plate upper 14, and the rotation of the knob 28 in the forward direction is regulated. The first regulating protrusion 28A and the second regulating protrusion 28B abut on the first regulating surface 14C of the regulating column 14B, and the rotation of the knob 28 in the reverse direction is regulated. For this reason, the rotatable range of the knob 28 is defined as the rotatable range between the first regulating protrusion 28A and the second regulating protrusion 28B between the regulating columns 14B.

By the way, when the brake 50 is not operated when the knob 28 is arranged at the “P” position, the rotor cam 42 is arranged at the first regulation position by the control of the control device 24 in the operating mechanism 40 (FIG. 4A and FIG. 5A). For this reason, the first contact pillar 54 A of the first lock bar 54 contacts the bottom surface of the first restriction hole 64 of the rotor cam 42, and the first lock bar 54 protrudes outside the support cylinder 14 A of the plate upper 14. . Further, the second contact bar 58A of the second lock bar 58 abuts on the peripheral surface of the release hole 62 of the rotor cam 42, and the second lock bar 58 does not protrude outside the support cylinder 14A. As a result, the first restricting projection 28A of the knob 28 comes into contact with the first lock bar 54 (surface contact), and the rotation of the knob 28 from the "P" position to the forward direction ("R" position) is restricted (locked). ) Is done.

On the other hand, when the brake 50 is operated when the knob 28 is arranged at the “P” position, the rotor cam 42 is arranged at the second restriction position by the control of the control device 24 in the operating mechanism 40 ( 4B and 5B). For this reason, the first contact pillar 54A of the first lock bar 54 abuts on the peripheral surface of the release hole 62 of the rotor cam 42, and the first lock bar 54 does not protrude outside the support cylinder 14A. As a result, the first restricting projection 28A of the knob 28 cannot be brought into contact with the first lock bar 54, and the rotation restriction of the knob 28 from the “P” position to the forward direction (“R” position) is released.

When the predetermined time does not elapse after the knob 28 is disposed at the “D” position, the operating mechanism 40 is disposed at the second restriction position of the rotor cam 42 under the control of the control device 24 (see FIG. 6A). Therefore, the second contact pillar 58A of the second lock bar 58 abuts on the bottom surface of the second restriction hole 66 of the rotor cam 42, and the second lock bar 58 protrudes outside the support cylinder 14A. As a result, the second regulating protrusion 28B of the knob 28 abuts (surface-contacts) with the second lock bar 58, and the rotation of the knob 28 from the “D” position to the forward direction (“M” position) is regulated. .

On the other hand, when a predetermined time has elapsed since the knob 28 was placed at the “D” position, the rotor cam 42 is placed at the release position under the control of the control device 24 in the operating mechanism 40 (see FIG. 6B). Therefore, the second contact column 58A of the second lock bar 58 abuts on the peripheral surface of the release hole 62 of the rotor cam 42, and the second lock bar 58 does not protrude outside the support cylinder 14A. As a result, the second regulating protrusion 28B of the knob 28 cannot be brought into contact with the second lock bar 58, and the rotation regulation of the knob 28 from the "D" position to the forward direction ("M" position) is released.

When the forward speed of the vehicle detected by the speedometer 52 is equal to or higher than a predetermined speed when the knob 28 is located at the “D” position, the “M” position, or the “N” position, the operation mechanism 40 Under the control of the device 24, the rotor cam 42 is arranged at the first restriction position (see FIG. 4A). Therefore, the first contact column 54A of the first lock bar 54 contacts the bottom surface of the first restriction hole 64 of the rotor cam 42, and the first lock bar 54 projects outside the support cylinder 14A. As a result, the first regulating protrusion 28A of the knob 28 abuts (surface-contacts) with the first lock bar 54, and the rotation of the knob 28 from the “N” position to the opposite direction (“R” position) is regulated. .

On the other hand, when the forward speed of the vehicle detected by the speedometer 52 is lower than the predetermined speed when the knob 28 is located at the “D” position, the “M” position, or the “N” position, the operation mechanism 40 Under the control of the control device 24, the rotor cam 42 is disposed at the second restriction position or the release position (see FIGS. 6A and 6B). For this reason, the first contact pillar 54A of the first lock bar 54 abuts on the peripheral surface of the release hole 62 of the rotor cam 42, and the first lock bar 54 does not protrude outside the support cylinder 14A. As a result, the first restricting projection 28A of the knob 28 cannot be brought into contact with the first lock bar 54, and the rotation restriction of the knob 28 from the "N" position to the reverse direction ("R" position) is released.

Here, the first lock bar 54 and the second lock bar 58 are moved radially outward of the knob 28 to restrict the rotation of the first restriction protrusion 28A and the second restriction protrusion 28B of the knob 28, respectively. The first lock bar 54 and the second lock bar 58 regulate the rotation of the knob 28. Further, the first lock bar 54 and the second lock bar 58 are moved radially inward of the knob 28 to release the rotation restriction of the first restriction protrusion 28A and the second restriction protrusion 28B of the knob 28, respectively. The first lock bar 54 and the second lock bar 58 release the rotation regulation of the knob 28.

For this reason, the rotation of the knob 28 can be restricted and released by using the first restriction projection 28A and the second restriction projection 28B that define the rotatable range of the knob 28, and the first lock bar 54 and the second lock Since it is not necessary to separately provide a portion whose rotation is restricted by the bar 58, the configuration of the shift device 10 can be simplified.

Further, in order to regulate the rotatable range of the knob 28 by the first regulating projection 28A and the second regulating projection 28B of the knob 28 and the first regulating surface 14C and the second regulating surface 14D of the plate upper 14, The dimension of the second regulating projection 28B in the circumferential direction of the knob 28 is sufficiently smaller than the distance between the first regulating surface 14C and the second regulating surface 14D in the circumferential direction of the knob 28. Therefore, when the first lock bar 54 and the second lock bar 58 are moved outward in the radial direction of the knob 28, the first lock bar 54 and the second lock bar 58 are respectively moved to the first restriction protrusion 28A and the second restriction bar. Interference with the projection 28B can be suppressed, and the rotation of the first restriction projection 28A and the second restriction projection 28B is restricted when the first lock bar 54 and the second lock bar 58 are moved radially outward of the knob 28, respectively. As a result, the first lock bar 54 and the second lock bar 58 can appropriately restrict the rotation of the knob 28.

In addition, the first lock bar 54 and the second lock bar 58 are orthogonal to the rotation direction (the circumferential direction of the knob 28) of the first control protrusion 28A and the second control protrusion 28B, respectively (radial direction and cross direction of the knob 28). Be moved. Therefore, the first lock bar 54 and the second lock bar 58 can effectively restrict the rotation of the first restriction protrusion 28A and the second restriction protrusion 28B, respectively, and can effectively restrict the rotation of the knob 28.

Furthermore, a first lock bar 54 and a second lock bar 58 are provided. For this reason, the regulation mode of the rotation of the knob 28 (the rotation position and the rotation range of the knob 28 to be regulated) can be increased.

Further, when the rotor cam 42 is rotated from the first restriction position to the second restriction position, the first lock bar 54 starts moving radially inward of the knob 28 and the second lock bar 58 radially outwards of the knob 28. And the time when the first lock bar 54 is moved radially inward of the knob 28 coincides with the time when the second lock bar 58 is moved radially outward of the knob 28 (overlap). Is done. For this reason, compared with the case where the second lock bar 58 starts moving the knob 28 to the outside in the radial direction after the movement of the first lock bar 54 to the inside of the knob 28 in the radial direction, the second lock bar 58 operates The second lock bar 58 can appropriately regulate the rotation of the knob 28 to the "M" position even when the knob 28 is quickly rotated to the "M" position. In addition, the first lock bar 54 moves the knob 28 relative to the case where the first lock bar 54 starts moving the knob 28 radially inward after the movement of the second lock bar 58 to the outside in the radial direction of the knob 28 is completed. The first lock bar 54 can appropriately release the rotation restriction of the knob 28 to the “R” position even when the knob 28 can be quickly moved inward in the radial direction and the knob 28 is quickly rotated to the “R” position.

Further, when the rotor cam 42 is rotated from the second restriction position to the first restriction position, the movement of the first lock bar 54 to the outside in the radial direction of the knob 28 and the second lock bar 58 to the inside in the radial direction of the knob 28 are started. And the time when the first lock bar 54 is moved radially outward of the knob 28 and the time when the second lock bar 58 is moved radially inward of the knob 28 coincide (overlap). Is done. For this reason, compared with the case where the second lock bar 58 starts moving the knob 28 inward in the radial direction after the end of the movement of the first lock bar 54 in the radial direction of the knob 28, the second lock bar 58 operates in the same manner as in the case where the knob 28 starts moving inward in the radial direction. Even when the knob 28 is quickly rotated to the “M” position, the second lock bar 58 can appropriately release the restriction on the rotation of the knob 28 to the “M” position. In addition, the first lock bar 54 moves the knob 28 relative to the case where the first lock bar 54 starts moving the knob 28 radially outward after the second lock bar 58 moves radially inward of the knob 28. The first lock bar 54 can appropriately regulate the rotation of the knob 28 to the “R” position even when the knob 28 can be quickly moved to the radially outer side and the knob 28 is quickly rotated to the “R” position.

(4) The knob 28 is rotated, and the shift position of the knob 28 is changed from the “D” position to the “M” position. For this reason, it is not necessary to provide a separate mechanism (for example, a switch mechanism) for changing the shift position of the knob 28 from the “D” position to the “M” position, and the number of parts can be reduced, and the cost can be reduced. And the size of the knob 28 can be reduced.

Furthermore, the second lock bar 58 is moved, and the rotation of the knob 28 from the “D” position to the “M” position is regulated and released. For this reason, unlike the case where the knob 28 is displaced in the axial direction and the rotation of the knob 28 from the “D” position to the “M” position is regulated and released, the knob 28 is moved from the “D” position to the “M” position. Erroneous operation to the position can be suppressed. In addition, when the knob 28 is rotated between the "D" position and the "M" position, the knob 28 can be prevented from being displaced to the axial position, and the rotation of the knob 28 can be improved, and Generation of abnormal noise when the knob 28 rotates can be suppressed.

In the present embodiment, the knob 28 is provided with a first regulating protrusion 28A and a second regulating protrusion 28B (defining portion), and the plate upper 14 is provided with a first regulating surface 14C and a second regulating surface 14D. However, the knob 28 may be provided with the first regulating surface 14C and the second regulating surface 14D (defining portion), and the plate upper 14 may be provided with the first regulating protrusion 28A and the second regulating protrusion 28B.

Further, in this embodiment, two regulating bodies (the first lock bar 54 and the second lock bar 58) are provided. However, one or three or more regulating bodies may be provided.

In the present embodiment, when the rotor cam 42 is rotated between the first restriction position and the second restriction position, the time required for the first lock bar 54 to move in the radial direction of the knob 28 and the second lock bar The time when the knob 58 is moved in the radial direction of the knob 28 is completely matched. However, when the rotor cam 42 is rotated between the first restriction position and the second restriction position, the time required for the first lock bar 54 to move in the radial direction of the knob 28 and the second lock bar 58 The time moved in the radial direction may be partially matched.

In the first and second embodiments, the shift device 10 is installed on the console. However, the shift device 10 may be installed on an instrument panel or a column cover.
