The sensor holder 72 is provided between the pair of mounting walls 42 described above. In particular, in the present embodiment, the center of the sensor holder 72 in the thickness direction is located immediately above the central axis of the shaft 18. Is set to

  As described above, the mounting wall 42 is inclined so as to be separated from each other upward above the intermediate portion in the vertical direction. However, as shown in FIG. When the shift lever 20 rotates around the shaft 18 to the RC position, the thickness direction above the intermediate portion in the vertical direction of the mounting wall 42 closer to the sensor holder 72 and the thickness direction of the sensor holder 72 are accordingly moved. The inclination angle of the mounting wall 42 is set so as to be substantially the same direction.

The shape of the mounting portion 40 is set so that the distance D2 between the mounting wall 42 closer to the sensor holder 72 and the sensor holder 72 becomes the same distance when the shift lever 20 rotates around.

  The sensor holder 72 includes a holder main body 74. The holder main body 74 is formed with a plurality (three in the present embodiment) of through holes 76, 78, and 80 that penetrate in the thickness direction. These through holes 76 to 80 are generally formed on the same circumference centering on the central axis of the shaft 32, and the through hole 76 positioned at the front most centered on the central axis of the shaft 32. The angle to the hole 78 is substantially equal to the rotation angle of the shift lever 20 from the “LF position” (“RF position”) to the “LC position” (“RC position”), and is the most about the central axis of the shaft 32. The angle between the rear through hole 80 and the central through hole 78 is the rotation angle of the shift lever 20 from the “LB position” (“RB position”) to the “LC position” (“RC position”). Is set to be approximately equal to

  A detection coil 84 constituting the proximity sensor 82 is disposed through the through hole 76, a detection coil 88 constituting the proximity sensor 86 is disposed through the through hole 78, and the proximity sensor 90 is disposed in the through hole 80. The detection coil 92 that constitutes is disposed through. The proximity sensors 82, 86, and 90 basically constitute a so-called “eddy current type proximity sensor”.

  For example, as shown in FIG. 7, the detection coil 84 of the proximity sensor 82 has one end connected to the high-frequency AC power supply 106 via a resistor 108 and the other end grounded. An oscillation state detection circuit and an output circuit (not shown) are connected between the resistor 108 and the detection coil 84, and further connected to an ECU 94 as control means as shown in FIG. 8 (detailed description is omitted). However, the proximity sensors 86 and 90 are the same as the proximity sensor 82).

  As shown in FIG. 7, the circuit including the detection coil 84 forms a so-called voltage dividing circuit. When the inductance of the detection coil 84 changes, the output voltage between the detection coil 84 and the resistor 108 is changed. Change. The ECU 94 shown in FIG. 8 is connected to the automatic transmission 96, and the ECU 94 outputs the output voltage between the detection coil 84 of the proximity sensor 82 and the resistor 108, and the output similarly output from the proximity sensors 86 and 90. The automatic transmission 96 is operated based on the voltage.

  On the other hand, as shown in FIGS. 1 and 3, attachment pieces 98 are continuously extended from both front and rear ends of the holder main body 74. Supporting portions 100 are formed on the side wall portions 16 constituting the lower housing 12 corresponding to these mounting pieces 98. The support portion 100 includes a lower wall portion 102 on which the attachment piece 98 is placed. Side wall portions 104 are erected upward from both left and right end portions of the lower wall portion 102. The distance between one side wall 104 and the other side wall 104 is substantially equal to the thickness dimension of the mounting piece 98, and the side wall 104 interferes from both the left and right sides of the mounting piece 98 placed on the lower wall 102. Thus, the displacement of the mounting piece 98 (that is, the sensor holder 72) in the left-right direction is restricted.

  In addition, the mounting portion 40 described above includes a copper piece 112 constituting the first moving body as a first conductive member that is a conductor, a second conductive member that is a conductor having a lower conductivity than the copper piece 112, and is magnetic. The iron piece 114 which comprises a 2nd moving body as a body is provided. The copper piece 112 is integrally attached to a surface of the attachment wall 42 located on the right side of the pair of attachment walls 42 that faces the sensor holder 72, of the pair of attachment walls 42. Of the three detection coils 84, 88, 90 described above with the shift lever 20 positioned at the neutral position in the center of the direction, the copper is attached to the mounting wall 42 so that the detection coil 88 located in the center and the copper piece 112 face each other. A piece 112 is provided.

  On the other hand, the iron piece 114 is integrally attached to the surface on the side facing the sensor holder 72 in the attachment wall 42 located on the left side of the pair of attachment walls 42 constituting the attachment portion 40. The iron piece 114 is provided on the mounting wall 42 so that the detection coil 88 and the iron piece 114 face each other in a state where the shift lever 20 is located at the neutral position in the center in the longitudinal direction of the hole 66.

  For this reason, when the shift lever 20 moves to the “LC position” that is the left end in the longitudinal direction of the select hole 66, the copper piece 112 provided on the right mounting wall 42 approaches the detection coil 88, and the shift lever 20 moves to the select hole. When moving to the “RC position” which is the right end of 66 in the longitudinal direction, the iron piece 114 provided on the left mounting wall 42 approaches the detection coil 88. Here, in the present embodiment, the distance from the copper piece 112 to the detection coil 88 along the left-right direction when the shift lever 20 has reached the “LC position”, and the shift lever 20 has reached the “RC position”. In such a state, the shapes, dimensions, and the like of various components are set so that the distance from the iron piece 114 to the detection coil 88 along the left-right direction becomes equal.

<Operation and effect of the present embodiment>
Next, the operation and effect of the present embodiment will be described.

  In the shift lever device 10 according to the present embodiment, the high-frequency AC power supply 106 is operated to cause a predetermined high-frequency AC current to flow through the detection coils 84, 88, 92 of the proximity sensors 82, 86, 90. A predetermined high-frequency magnetic field is formed around the detection coils 84, 88 and 92. In this state, for example, when the shift lever 20 in the neutral position is rotated to the left around the shaft 18 to the “LC position” that is the left end in the longitudinal direction of the select hole 66, the (LC position) in FIG. As shown in the drawing, of the pair of mounting walls 42 constituting the mounting portion 40, the right mounting wall 42 approaches the sensor holder 72 and the left mounting wall 42 is separated from the sensor holder 72.

  When the right mounting wall 42 approaches the sensor holder 72 and the copper piece 112 approaches the detection coil 88 of the proximity sensor 86, an induction current is generated in the copper piece 112 by the high-frequency magnetic field formed around the detection coil 88. . Thus, when an induced current is generated in the copper piece 112, the high-frequency magnetic field is attenuated, thereby changing the inductance of the detection coil 88. When the inductance of the detection coil 88 changes in this way, as shown in FIG. 9, the output voltage of the voltage dividing circuit including the detection coil 88 of the proximity sensor 86 attenuates from V0 to VL.

  On the other hand, when the shift lever 20 in the neutral position is rotated to the right around the shaft 18 to the “RC position” that is the right end of the select hole 66 in the longitudinal direction, it is shown in the (RC position) diagram of FIG. As described above, of the pair of mounting walls 42 constituting the mounting portion 40, the left mounting wall 42 approaches the sensor holder 72 and the right mounting wall 42 is separated from the sensor holder 72.

  When the left mounting wall 42 approaches the sensor holder 72 and the iron piece 114, which is a magnetic material, approaches the detection coil 88 of the proximity sensor 86, the iron piece 114 becomes a magnetic path of a magnetic flux constituting an AC magnetic field, and the AC magnetic field is converted into the iron piece 114. Pass through. Thereby, although the inductance of the detection coil 88 changes, unlike the case of the copper piece 112, the output of the voltage dividing circuit configured to include the detection coil 88 of the proximity sensor 86 as shown in FIG. The voltage increases from V0 to VR.

  As described above, when the copper piece 112 approaches the sensor holder 72, the output voltage of the voltage dividing circuit including the detection coil 88 is attenuated, and when the iron piece 114 approaches the sensor holder 72, Since the output voltage of the voltage dividing circuit including the detection coil 88 increases, detection is performed when the shift lever 20 is rotated to the “LC position” and when the shift lever 20 is rotated to the “RC position”. Since the level of the electric signal input from the coil 88 to the ECU 94 is different, the ECU 94 determines the level of the input electric signal so that the shift lever 20 is rotated to the “LC position” or turned to the “RC position”. You can determine whether it has moved.

  Further, as shown in the (LF position) diagram of FIG. 4, in order to rotate the shift lever 20 to the “LF position”, the shift lever 20 is moved to the “LC position” and then moved to the left shift hole 62. Then, the shift lever 20 is rotated forward around the shaft 32. When the shift lever 20 passes through the left shift hole 62, the right mounting wall 42 approaches the sensor holder 72 and the left mounting wall 42 is separated from the sensor holder 72. Therefore, when the left shift hole 62 is rotated to the “LF position”, the copper piece 112 approaches the detection coil 84 of the proximity sensor 82 instead of the detection coil 88 of the proximity sensor 86. As a result, the output voltage of the voltage dividing circuit including the detection coil 84 is attenuated from V0 to VL. Thereby, it can be detected that the shift lever 20 has been rotated to the “LF position”.

  On the other hand, as shown in the (RF position) diagram of FIG. 5, in order to rotate the shift lever 20 to the “RF position”, the shift lever 20 is moved to the “RC position” and then the right shift is performed. The shift lever 20 is rotated forward around the shaft 32 along the hole 64. When the shift lever 20 is passing through the right shift hole 64, the left mounting wall 42 approaches the sensor holder 72 and the right mounting wall 42 is separated from the sensor holder 72. For this reason, when the inside of the right shift hole 64 is rotated to the “RF position”, the iron piece 114 approaches the detection coil 92 of the proximity sensor 90 instead of the detection coil 88 of the proximity sensor 86. As a result, the output voltage of the voltage dividing circuit including the detection coil 92 increases from V0 to VR. Thereby, it can be detected that the shift lever 20 has been rotated to the “RF position”.

  Also, as shown in the (LB position) diagram of FIG. 4, in order to rotate the shift lever 20 to the “LB position”, the shift lever 20 is moved to the “LC position” and then moved to the left shift hole 62. Then, the shift lever 20 is rotated backward around the shaft 32. When the shift lever 20 passes through the left shift hole 62, the right mounting wall 42 approaches the sensor holder 72 and the left mounting wall 42 is separated from the sensor holder 72. Therefore, when the left shift hole 62 is rotated to the “LB position”, the copper piece 112 approaches the detection coil 92 of the proximity sensor 90 instead of the detection coil 88 of the proximity sensor 86. As a result, the output voltage of the voltage dividing circuit including the detection coil 92 is attenuated from V0 to VL. Thereby, it can be detected that the shift lever 20 has been rotated to the “LB position”.

  On the other hand, as shown in the (RB position) diagram of FIG. 5, in order to rotate the shift lever 20 to the “RB position”, the shift lever 20 is moved to the “RC position” and then the right shift is performed. The shift lever 20 is rotated backward around the shaft 32 along the hole 64. When the shift lever 20 is passing through the right shift hole 64, the left mounting wall 42 approaches the sensor holder 72 and the right mounting wall 42 is separated from the sensor holder 72. For this reason, when the inside of the right shift hole 64 is rotated to the “RB position”, the iron piece 114 approaches the detection coil 92 of the proximity sensor 90 instead of the detection coil 88 of the proximity sensor 86. As a result, the output voltage of the voltage dividing circuit including the detection coil 92 increases from V0 to VR. Thereby, it can be detected that the shift lever 20 has been rotated to the “RB position”.

  As described above, in the shift lever device 10 according to the present embodiment, if the rotation position of the shift lever 20 around the shaft 32 is the same detection position, it can be detected by one of the proximity sensors 82, 86, 90. is there. For this reason, in the present shift lever device 10, although the detection positions of the shift lever 20 are set at three positions on the left shift hole 62 side and three positions on the right shift hole 64 side, a total of six detection positions are set. The position of the shift lever 20 can be detected with fewer three proximity sensors 82, 86, 90. Thereby, cost can be reduced.

(Supplementary information)
In the present embodiment, the first moving body is composed of a copper piece 112 that is a conductor, and the second moving body is composed of an iron piece 114 that is a magnetic body. However, if a so-called “eddy current proximity sensor” is applied to the detection means, both the first moving body and the second moving body may be formed of nonmagnetic conductors. In this case, if the distance D1 between the one mounting wall 42 and the sensor holder 72 and the distance D2 between the other mounting wall 42 and the sensor holder 72 are set to the same distance, the conductivity of the first moving body. And the second moving body may have different conductivity, and if the first moving body and the second moving body have the same conductivity, the mounting portion 40 may be configured so that the distance D1 and the distance D2 are different. Good. Of course, the interval D1 and the interval D2 may be made different after the conductivity of the first moving body and the conductivity of the second moving body are made different.

  On the other hand, both the first moving body and the second moving body may have magnetism. Also in this case, if the distance D1 and the distance D2 are set to the same distance, the permeability of the first moving body may be different from the permeability of the second moving body. If the two moving bodies have the same magnetic permeability, the attachment portion 40 may be configured so that the distance D1 and the distance D2 are different. Of course, the interval D1 and the interval D2 may be made different after the permeability of the first moving body and the permeability of the second moving body are made different.

  However, when both the first moving body and the second moving body are made of a non-magnetic conductor, or when both the first moving body and the second moving body are made of a magnetic body, the detection coils 84 to 92 are connected. In the process in which one of the first moving body and the second moving body approaches, the output voltage of the voltage dividing circuit including the detection coils 84 to 92 is in the state where the other of the first moving body and the second moving body approaches. Could be the same. For this reason, in such a configuration, for example, when the state in which the output voltage has changed has not been continued for a certain period of time, a detection signal is not output from the proximity sensors 82, 86, 90, or the detection input by the ECU 94 is detected. You must cancel the signal.

  However, as described above, when one of the first moving body and the second moving body is a magnetic body and the other is a non-magnetic conductor, the first movement to the detection coils 84 to 92 is performed as described above. The change in output voltage is reversed between when the body approaches and when the second moving body approaches the detection coils 84 to 92. For this reason, in the process in which one of the first moving body and the second moving body approaches the detection coils 84 to 92, the output voltage changes and the other of the first moving body and the second moving body approaches the detection coils 84 to 92. Thus, the output control of the detection signals in the proximity sensors 82, 86, 90 and the processing of the detection signals in the ECU 94 are simplified.

  Furthermore, in the present embodiment, the so-called “eddy current proximity sensor” is applied to the detection means as described above, but the detection means is not limited to such a configuration, and the so-called “proximity sensor” is used. Any medium can be applied as long as it is present, and the medium detected by the detecting means is not limited in any way. For example, a permanent magnet may be used in place of the copper piece 112 or the iron piece 114, and a magnetic sensor that detects the magnetism of the permanent magnet may be used as a detection means that replaces the proximity sensors 82, 86, and 90.

  In the case of such a configuration, for example, a case where a permanent magnet provided on one of the pair of mounting walls 42 approaches the magnetic sensor is distinguished from a case where a permanent magnet provided on the other mounting wall 42 approaches the magnetic sensor. The magnetic characteristics may be changed between the permanent magnet provided on one of the pair of mounting walls 42 and the permanent magnet provided on the other mounting wall 42 so as to be able to do so. Further, if a permanent magnet having the same magnetic characteristics is used, the permanent magnet is provided in a state in which the direction of the magnetic pole with respect to the magnetic sensor is changed, or the permanent magnet provided on one of the pair of mounting walls 42 is close to the magnetic sensor. The mounting portion 40 is set so that the distance between the magnetic sensor and the magnetic sensor and the distance between the permanent magnet and the magnetic sensor when the permanent magnet provided on the other of the pair of mounting walls 42 is close to the magnetic sensor are different. It is good also as a structure.

  In the present embodiment, the operating range of the shift lever 20 is substantially H-shaped in which the middle portions of the left shift hole 62 and the right shift hole 64 are connected by the select hole 66. A substantially U shape in which one end of the right shift hole 64 is connected by a select hole 66 may be used. Further, it has only a left shift hole 62 (or right shift hole 64), and has a substantially T shape or bowl shape in which one end of the select hole 66 is connected to an intermediate portion or one end portion of the left shift hole 62 (or right shift hole 64). The operation range of the shift lever 20 may be limited to the select hole 66 only.

  Furthermore, in the present embodiment, the movement direction of the shift lever 20 along the select hole 66 is the first operation direction, but the operation direction of the shift lever along the shift hole intersecting the select hole 66 is the first operation direction. You may comprise so that it may become an operation direction.

  In the present embodiment, the shift lever 20 that can be selected and moved around the shaft 18 and can be shifted around the shaft 30 is used as the operating means. However, the operating means is not limited to such a configuration. Absent. For example, a slider that can slide in the front-rear direction and the left-right direction in the present embodiment may be used as the operation means.
