  The shift rotation shaft 22 is generally resin-molded in a substantially rectangular parallelepiped shape, and has an opening 22a through which the center support portion 210c of the shift lever 21 is inserted in the vertical direction thereof. A pair of rotating shaft portions 22b and 22c are provided at both ends in the direction of the central axis C1. A mounting hole 22d through which the select rotation shaft 23 is inserted is formed in a direction perpendicular to the first rotation center axis C1 of the shift rotation shaft 22.

  The select rotation shaft 23 has a support shaft portion 23a and a head portion 23b, and a push nut 23c can be attached to and detached from the tip end portion of the support shaft portion 23a. Then, the center support portion 210c of the lever block 210 is inserted through the opening 22a of the shift rotation shaft 22, and the mounting hole 22d and the support hole 210b are arranged in a straight line. The shaft 23 is inserted through the support shaft 23a and is secured with a push nut 23c. As a result, the shift lever 21 can swing around the second rotation center axis C2 perpendicular to the first rotation center axis C1.

  The main case 6 is resin-molded in a substantially rectangular parallelepiped shape, and a flat rectangular storage portion 61 for storing the shift rotation shaft 22 is integrally provided on the upper surface 6a thereof. The main case 6 is formed with a mounting hole 62 having a rectangular cross section on the side wall in the direction along the first rotation center axis C1. Further, flanges 63 for attaching to a vehicle body side member (not shown) are provided on both side walls in the direction along the second rotation center axis C2 described above. The flange 63 is formed with a mounting hole 63a through which a mounting bolt (not shown) is inserted.

And after inserting the rotating shaft parts 22b and 22c in these bearing parts 61c and 61d, each front-end | tip part is fitted to the resin collar 64, and the shift rotating shaft 22 is kept out.

  In this way, by rotating and supporting the shift rotation shaft 22 on the bearing portions 61c and 61d of the main case 6, the shift lever 21 can swing around the first rotation center axis C1 and can be shifted. Further, the support hole 210b is rotatably supported by the select rotation shaft 23 fitted to the shift rotation shaft 22, so that the select operation can be performed around the second rotation center axis C2 of the select rotation shaft 23. .

  As shown in FIG. 1, the shift lever 21 moves (oscillates) between the home position (H) and the neutral position (N) and operates in the shift direction from the neutral position (N) as shown in FIG. By operating, it selectively moves (oscillates) between the drive position (D) and the reverse position (R), thereby forming a T-shaped operation path. When the home position (H) is operated to the neutral position (N) and when the neutral position (N) is operated to the drive position (D) or the reverse position (R), the knob 24 is operated at the operated position. When the hand is released, the check mechanism 5 described later automatically returns to the home position (H) (self-return). Here, the home position (H) is an initial position, while the neutral position (N), the drive position (D), and the reverse position (R) are each an operation position.

  The lever position detection unit 3 is built in the iron plate 31 as a detection object facing the lower part 210d of the shift lever 2, the case 32 that is attached to the bottom of the main case 6 and accommodates the iron plate 31, and the lower part 210d of the shift lever 2. And a plurality of sensors S1, S2 and S3 for detecting the iron plate 31.

  The iron plate 31 is formed in a predetermined shape, for example, a U-shape as shown in FIG. 6B, and has a base 311 extending in the shift direction (vehicle longitudinal direction), and a select direction (vehicle left direction) from both ends of the base 311. ) And the projecting portions 312 and 313 extending respectively.

  When the shift lever 21 is in the home position (H), the first sensor S1, the second sensor S2, and the third sensor S3 are in the positions indicated by the solid circles in FIG. 6B, that is, the first sensor. S1 is located between the protrusions 312 and 313 and deviates from the region facing the iron plate 31, and the second sensor S2 and the third sensor S3 face the tips of the protrusions 312 and 313 of the iron plate 31, respectively. As a result, as shown in FIG. 7, when the first sensor S1 is turned OFF and the second sensor S2 and the third sensor S3 are turned ON, it is detected that the shift lever 21 is at the home position (H).

  When the knob 24 of the shift lever 21 is gripped and swung from the home position (H) to the select direction (the vehicle left direction) to move to the neutral position (N), the lower portion 210d of the shift lever 21 moves to the vehicle right direction. By moving, the first sensor S1, the second sensor S2, and the third sensor S3 are in positions indicated by broken-line circles in FIG. 6B, that is, the first sensor S1 is the longitudinal length of the base 311 of the iron plate 31. The second sensor S <b> 2 and the third sensor S <b> 3 are opposed to both ends in the longitudinal direction of the base 311, respectively, while facing the center of the direction. As a result, as shown in FIG. 7, when the first sensor S1, the second sensor S2, and the third sensor S3 are turned on, it is detected that the shift lever 21 is positioned at the neutral position (N).

  When the lever 24 of the shift lever 21 is operated to the reverse position (R) by grasping the knob 24 of the shift lever 21 and swinging from the neutral position (N) to the shift direction (front direction of the vehicle), the lower portion 210d of the shift lever 21 is moved rearward of the vehicle. Since the first sensor S1 is opposed to the longitudinal end of the base 311 of the iron plate 31, the second sensor S2 is opposed to the longitudinal center of the base 311 and the third sensor S3 is Deviate from the facing area. As a result, as shown in FIG. 7, when the first sensor S1 and the second sensor S2 are turned on and the third sensor S3 is turned off, it is detected that the shift lever 21 is located at the reverse position (R). .

  Further, when the knob 24 of the shift lever 21 is grasped and swung from the neutral position (N) to the shift direction (rear direction of the vehicle) and operated to the reverse position (D), the lower portion 210d of the shift lever 21 is moved forward of the vehicle. Since the first sensor S1 is opposed to the longitudinal end of the base 311 of the iron plate 31, the second sensor S2 is separated from the region facing the iron plate 31, and the third sensor S3 is Opposite the center in the longitudinal direction. As a result, as shown in FIG. 7, when the first sensor S1 and the third sensor S3 are turned on and the second sensor S2 is turned off, it is detected that the shift lever 21 is located at the reverse position (D). .

  The lever restricting portion 4 includes a gate pin 41 that behaves integrally with the shift lever 21, and a gate block 42 having a T-shaped gate groove portion 421 that guides the gate pin 41.

The check ball 512 is protruded from the tip, and the check spring 513 is housed in the hollow portion of the check rod 511 so that the check ball 512 is pressed against the check surface 521 of the check block 52.

  In this embodiment, as shown in FIG. 3, the shift lever 21 is integrally provided with a gate pin 41 and a check unit 51.

  Specifically, as shown in FIG. 3, the gate pin 41 is formed at the lower end of the lever block 210 so as to be inclined by a specified angle with respect to the axis of the shift lever 21 about the support hole 210 b of the lever block 210. The pin insertion hole 210e is press-fitted and fixed.

  At this time, the tip 41a of the gate pin 41 protrudes from the pin insertion hole 210e, and the tip 41a is inserted in close contact with the opening 432 of the silencer damper 43 and the gate groove 421 of the gate block 42 so as to be movable. Therefore, when the shift lever 21 is operated, the gate pin 41 moves in the gate groove portion 421 so that the selection operation and the shift operation are guided while the movement of the shift lever 21 is restricted.

  As shown in FIG. 3, the check portion 51 is inclined at a lower end portion of the lever block 210 by a specified angle around the support hole 210b on the side opposite to the pin insertion hole 210e described above with respect to the axis of the shift lever 21. It is stored in the storage hole 210f formed in this way. A check spring 513 and a check rod 511 are inserted in this order into the storage hole 210f, and the check spring 513 biases the tip of the check rod 511 provided with the check ball 512 in a direction protruding from the storage hole 210f.

  Therefore, as shown in FIGS. 3 and 4, the check ball 512 is pressed against the check surface 521 of the check block 52 with a specified pressing force, and an appropriate operating force is applied to the shift lever 21 and the home position (H). Automatic home return function when moving (swinging) from the neutral position (N), reverse position (R), and drive position (D), that is, the function that the shift lever 21 automatically returns to the home position (H) have.

  Further, in this embodiment, as shown in FIG. 2, the gate block 42 and the check block 52 are integrally molded as a single united block 7, and the united block 7 is inserted into the mounting hole 62 of the main case 6. It is fitted and fixed.

It is formed. The iron plate 31 and the lower portion 210d of the shift lever 21 face each other through these openings 61e and 7a, and the case 32 is mounted so as to cover the lower side of the openings 61e and 7a.

  According to the shift device 1 of the present embodiment having the above configuration, the iron plate 31 of the lever position detection unit 3 is attached to the main case 6 via the case 32, and the plurality of sensors S1 to S3 are attached to the lower portion 210d of the shift lever 21. Since the shift device 1 is smaller in size in the height direction than the conventional example in which the lever position detecting portion is connected to the lower portion of the shift lever via a connecting rod, the size of the shift device 1 can be reduced. In addition, since there is no influence due to variations in the dimensions of the connecting portion such as the connecting rod as in the prior art, the detection accuracy of the position of the shift lever 21 by the plurality of sensors S1 to S3 can be improved, and further, the lever position detecting portion Since the rod and its mounting work are unnecessary, it is possible to reduce the parts cost and work cost.

  Further, in the present embodiment, the select operation position and the shift operation position of the shift lever 21 are detected by the plurality of sensors S1 to S3 reacting to the iron plate 31 formed in a predetermined shape and turning on and off respectively. Therefore, the number of sensors can be relatively reduced by appropriately setting the shape of the iron plate 31, and the cost can be reduced and the installation space can be reduced for the sensors.

  In the present embodiment, the sensors S1 to S3 of the lever position detector 3 are built in the lower part 210d of the shift lever 21. Therefore, the sensors S1 to S3 are arranged below the shift lever 21 while effectively using the space in the main case 6. 210d can be provided integrally.

  In the present embodiment, the sensors S1 to S3 of the lever position detection unit 3 are coil sensors, and the detection target is an iron plate 31, so the lever position detection unit includes a magnet and a Hall IC sensor. In comparison, the shape processing of the iron plate 31 can be performed more easily and the cost of parts can be reduced. In this respect as well, the cost can be reduced.

  In the present embodiment, since the three sensors S1 to S3 of the lever position detection unit 3 are provided in the lower part 210d of the shift lever 21 and arranged at three locations along the shift direction of the shift lever 21, the sensors S1 to S3 Two or more of them operate in response to the iron plate 31, so that it is possible to detect which of the four shift positions the shift lever 21 is in. Therefore, the cost and installation space regarding the sensors S1 to S3 can be reduced as compared with the conventional example including the lever position detection unit having seven sensors. Furthermore, since four or more shift positions are detected when two or more of the three sensors S1 to S3 are turned ON, if any one of the three sensors S1 to S3 breaks down Thus, the occurrence of this failure can be detected, and therefore safety can be improved.

It is also possible to reduce the size and make it more compact.

  Further, in the present embodiment, one or more of the sensors S1 to S3 of the lever position detection unit 3 are activated in response to the iron plate 31A, thereby determining which of the six shift positions the shift lever 21 is in. Can be detected.

  The other iron plate 31B shown in FIG. 12 has a protruding portion 315 extending in the select direction (the vehicle left direction) from the center in the longitudinal direction of the base 311.

  With the iron plate 31B, when the shift lever 21 is in the home position (H), the first sensor S1, the second sensor S2, and the third sensor S3 are in the positions indicated by the solid circles in FIG. That is, the first sensor S1 is opposed to the tip of the protruding portion 315 of the iron plate 31B, and the second sensor S2 and the third sensor S3 are each separated from the region facing the iron plate 31B. As a result, as shown in FIG. 13, the first sensor S1 is turned on, and the second sensor S2 and the third sensor S3 are turned off to detect that the shift lever 21 is at the home position (H).

  When the shift lever 21 is operated to the shift-up position (+), the first sensor S1 and the third sensor S3 are out of the region facing the iron plate 31B, and the second sensor S2 is opposed to the tip of the protruding portion 315 of the iron plate 31B. To do. As a result, as shown in FIG. 13, when the first sensor S1 and the third sensor S3 are turned off and the second sensor S2 is turned on, it is detected that the shift lever 21 is located at the upshift position (+). To do.

  When the shift lever 21 is operated to the shift-down position (−), the first sensor S1 and the second sensor S2 are out of the region facing the iron plate 31B, and the third sensor S3 faces the protruding portion 315 of the iron plate 31B. As a result, as shown in FIG. 13, since the first sensor S1 and the second sensor S2 are turned off and the third sensor S3 is turned on, it is detected that the shift lever 21 is located at the shift down position (−).

  Even if the steel plate 31B is provided as described above, the same effects as those provided with the iron plate 31A described above can be obtained.

  In the first to third embodiments, since the lower portion 210d of the shift lever 21 has an arc shape, the distance between the sensors S1 to S3 and the iron plate 31 changes, so the distance between the sensor and the iron plate is kept constant. Therefore, when the iron plate 31 is curved along the arc shape of the lower portion 210d of the shift lever 21, the detection accuracy of the sensors S1 to S3 is improved.

  Furthermore, the sensors S1 to S3 are not limited to the coil sensors, but may be any sensors that can be attached to the shift lever 21 (for example, Hall IC). The number of sensors is not limited to three in the embodiment, and a plurality of three or more. It does not matter.
