A shifting device 1 includes: a rotor member 80 pivotally-supported by a base member 30 in a turnable manner, and configured to turn following a shifting direction of a shift lever 10; a lever member 90 pivotally-supported by the base member 30 in a turnable manner, and configured to turn following a selecting direction of the shift lever 10; a hall sensor 71 as a detector member mounted on a circuit board 70 and facing against a detection target section of the rotor member 80; and a hall sensor 72 mounted on a surface of the circuit board 70, and facing against a detection target section of the lever member 90, the surface being identical to a surface on which the hall sensor 71 is mounted.
Description
- The present invention relates to a shifting device mounted on a vehicle in order to shift a shift position.
- Conventionally, a shifting device that detects a shift position using a sensor (see PTL 1) is configured such that hall ICs are provided on a single circuit board, a shifting direction is detected by a rotational position of a magnet, and a selecting direction is detected by a change in a magnetic flux when a yoke moves in an axial direction with respect to the magnet. In this manner, as a mechanism in which directions for detection are different between the shifting direction and the selecting direction has conventionally been employed, a stroke of operation largely varies depending on the direction and thus a structure of the device increases in size. Further, as a magnetoresistive element is used, detection of the shifting direction in a rotational direction is susceptible to temperature change.
- Moreover, in a case of the shifting device employing a conventional sensor, water or the like running down the shift lever may possibly enter into the shifting device. As water or the like reaching the sensor becomes a cause of failure or the like, it is desired to take measures against water exposure for the shifting device employing a sensor. However, according to the technique of PTL 1 described above, as guide grooves such as a shift gate and a select gate are opening upward, taking measures against water exposure has been difficult.
- Furthermore, conventionally, while a mechanism of shift-locking when an engine is turned off (e.g., PTL 2) has been provided, the shift-lock is performed using solenoid, and whether or not a state is in a shift-lock state has not been detected. In addition, while there is known a device provided with a function for, if it is detected that the shift lever is not at a home position but in a manual position when an engine is turned off, retuning the shift lever to the home position, such a function is provided separately from the shift-lock mechanism.

As thecontainer opening 32 opens to a direction opposite of the opening of theconcave section 31, theconcave section 31 and thecontainer opening 32 may be provided by asingle base member 30. Further, with thecasing 40 that will be later described, it is possible to easily provide a configuration in which theconcave section 31 and thecontainer opening 32 are fully covered. - The
base member 30 further includes a first pivotally-supportingsection 34 and a second pivotally-supportingsection 35 pivotally-supporting, respectively, therotor member 80 and thelever member 90 in a turnable manner. - The first pivotally-supporting
section 34 pivotally-supports ashaft section 80 a of therotor member 80 in a manner turnable following swinging of theshift lever 10 in the shifting direction. - The second pivotally-supporting
section 35 pivotally-supports ashaft section 90 a of thelever member 90 in a manner turnable following swinging of theshift lever 10 in the selecting direction. - As illustrated in
FIG. 9 andFIG. 8 , the first pivotally-supportingsection 34 and the second pivotally-supportingsection 35 are provided in a shape in which cut-outopenings openings rotor member 80 and thelever member 90 are attached by positioning and inserting corresponding retaining sections of therotor member 80 and thelever member 90 respectively in the cut-outopenings - The
base member 30 further includes holdingplates 36 inserted into throughholes 43 that will be later described in thecasing 40 around theconcave section 31. - The
casing 40 is in a box shape opening downward (negative Z side) so as to accommodate, along with thecircuit board 70, thebase member 30 to which thecircuit board 70 is attached. Thecasing 40 also includes a box section opening upward (positive Z side), where theclick member 12 attached to theball section 11 and a part of theguide case 50 are accommodated. -
FIG. 10 is an upper view illustrating thecasing 40. -
FIG. 11 is a sectional view of thecasing 40 taken along line indicated by an arrow F-F inFIG. 10 . - The
casing 40 includes aball containing section 41 substantially in a cylindrical shape larger than theball section 11 at a position where theball section 11 is accommodated. Along an inner circumference of theball containing section 41,elastic claw sections 42 and the throughholes 43 are provided. - Each of the
elastic claw sections 42 includes a catchingsection 42 a engaged with theball section 11 in an axial direction of the shift lever 10 (Z direction). In this embodiment, the catchingsections 42 a are provided at four positions. - Each of the through
hole 43 is provided penetrating through in an up-down direction (Z direction) on a rear side of the correspondingelastic claw section 42, that is, on a side opposite of the side on which the catchingsection 42 a projects to accommodate the ball section 11 e. -
FIG. 12 is an enlarged sectional view illustrating of a portion of thecasing 40 near theelastic claw section 42 along with theball section 11 and thebase member 30, before theball section 11 and thebase member 30 are assembled. - In the state in which the
base member 30 is not attached to thecasing 40, theelastic claw sections 42 provided for thecasing 40 are allowed to elastically deform respectively toward the throughholes 43 so that theball section 11 maybe inserted through the catchingsections 42 a in the axial direction of the shift lever 10 (Z direction). -
FIG. 13 is an enlarged sectional view illustrating a portion of thecasing 40 near theelastic claw section 42 with theball section 11 and thebase member 30 being assembled. - In the
casing 40, theball section 11 is first inserted through the catchingsections 42 a in the axial direction of the shift lever 10 (Z direction), and then thebase member 30 is attached to thecasing 40. In the state in which thebase member 30 is attached to thecasing 40, each of the holdingplates 36 is inserted into the corresponding throughhole 43 and positioned between the rear side of the correspondingelastic claw section 42 and the ball containing section. In this state, the holdingplates 36 inserted through the throughholes 43 prevents elastic deformation of theelastic claw sections 42 provided for thecasing 40. Thus, theelastic claw sections 42 are not allowed to elastically deform in the state in which the catchingsections 42 a are engaged with theball section 11. In this manner, theball section 11 is reliably held by thebase member 30 and thecasing 40 in the state in which theshift lever 10 is allowed to swing. - The
guide case 50 is provided between theball section 11 and theguide member 20. In a plane on a downward side (negative Z side) of theguide case 50, clickgrooves 51 are provided at positions corresponding to positions of theclick member 12 that moves according to the shift position of theshift lever 10. Further, aguide groove 52 similar to theguide groove 21 of theguide member 20 opens in theguide case 50, and theshift lever 10 penetrates through theguide groove 52. - Similarly to the
guide groove 21, theguide groove 52 also guides theshift lever 10 to the plurality of operational positions. It should be noted that theguide groove 52 guides theshift lever 10 by contact, and theguide case 50 receives a load from theshift lever 10. Therefore, theguide case 50 is securely fixed to thecasing 40 using ashaft 53. - The
guide cover 60 is provided at a position between theguide member 20 and theguide case 50 so as to be movable in an XY plane. In theguide cover 60, around hole 61 that is substantially as large as the outer shape of theshift lever 10 opens, and theshift lever 10 penetrates through theround hole 61. The guide cover 60 moves to cover theguide groove 52 of theguide case 50 as theshift lever 10 swings, and thus to provide a favorable external appearance as well as to prevent a foreign matter from entering inside. - The
circuit board 70 is positioned within thecontainer section 33 of thebase member 30 so that its board surface is parallel with an YZ plane. Thecircuit board 70 is provided withhall sensors shift lever 10, and thehall sensors magnet 82 of therotor member 80 and amagnet 92 of thelever member 90. - The hall sensor (first detector member) 71 detects a rotational angle of the
magnet 82 when therotor member 80 rotates according to swinging of theshift lever 10 in the shifting direction in a state in which themagnet 82 faces against thehall sensor 71. As thehall sensor 71, a hall IC is used, capable of detecting a change in an angle of a magnetic flux due to rotation of themagnet 82, and outputting, as a detection signal, a voltage corresponding to the detected angle of the magnetic flux. - By the
hall sensor 71 detecting the rotational angle of themagnet 82, it is possible to determine whether theshift lever 10 has moved to the positive Y side or to the negative Y side in the shifting direction. - The hall sensors (second detector member) 72 detect whether or not the
magnet 92 is at a facing position when thelever member 90 moves themagnet 92 either away from or closer to thehall sensors 72 according to swinging of theshift lever 10 in the selecting direction. As thehall sensors 72 only need to determine the presence of themagnet 92, a hall IC that only outputs ON or OFF. - By the
hall sensors 72 detecting the position of themagnet 92, it is possible to determine whether theshift lever 10 has moved to the positive X side (either of R, N, and D) or to the negative X side (neutral position, which is the state shown inFIG. 1 , or B position) in the selecting direction. - Further, while the two
hall sensors 72 are provided in this embodiment so that it is possible to perform detection even if there is a trouble with one of the sensors, only onehall sensor 72 may be provided. - The rotor member (first detection target member) 80 is pivotally-supported by the
base member 30 in a turnable manner, and configured to turn following swinging of theshift lever 10 in the shifting direction. Therotor member 80 holds the magnet (detection target section) 82 at one end section (end section on the negative X side) in a manner rotatable in a plane vertical to the rotational axis of theshift lever 10 in the shifting direction (in an YZ plane). Themagnet 82 is provided for therotor member 80 such that both of its N pole and S pole face against thehall sensor 71. - To the other end section of the rotor member 80 (end section on the positive X side), the
engagement piece 81 is fixed. Theengagement piece 81 is engaged with theengagement groove 11 a provided in a direction of an operational axis of theshift lever 10, and rotates following movement of theshift lever 10 in the shifting direction. - The lever member (second detection target member) 90 is pivotally-supported by the
base member 30 in a turnable manner, and configured to turn following swinging of theshift lever 10 in the selecting direction. Thelever member 90 holds the magnet (detection target section) 92 at one end section of anarm section 90 b (end section on the negative X side) extending in a direction vertical to the rotational axis of the selecting direction. In this embodiment, themagnet 92 is provided for thelever member 90 so as to face against thehall sensors 72 when theshift lever 10 is in the center position. To the other end section of the lever member 90 (end section on the positive X side), theengagement piece 91 is fixed. Theengagement piece 91 is engaged with theengagement groove 11 b provided in the direction of the operational axis of theshift lever 10, and rotates following movement of theshift lever 10 in the selecting direction. - The
magnet 92 of this embodiment is configured such that its N pole is on a tip end side (a side closer to the hall sensors 72), and a side of the N pole (tip end side) is configured thinner than a side of an S pole so as to facilitate determination of a polar direction. It should be noted that if thehall sensors 72 are for S pole, the S pole may be on the tip end side of themagnet 92. - As described above, the
rotor member 80 and thelever member 90 are connected to theball section 11 respectively via theengagement piece 81 and theengagement piece 91, and therefore therotor member 80 and thelever member 90 are able to rotate independently from each other without hindering the movement of theshift lever 10 in the shifting direction and the selecting direction. -
FIG. 14 is a chart showing an output waveform of thehall sensor 71 with a linear output. -
FIG. 15 is a chart showing an output waveform of thehall sensor 71 with a non-linear output. - As described above, a hall IC capable of detecting a rotational angle is used as the
hall sensor 71, and thehall sensor 71 detects the change in the angle of the magnetic flux due to the rotation of themagnet 82, and outputs, as the detection signal, a voltage corresponding to the detected angle of the magnetic flux. For example, it is possible to use a linear hall IC having a linear waveform (linear output) as shown inFIG. 14 , or a hall IC having a non-linear waveform (non-linear output) as shown inFIG. 15 . With the latter, it is possible to freely set an output of the hall IC without changing specification of an output-side higher ECU that is not shown. In this embodiment, the output waveform of thehall sensor 71 changes such that the output voltage changes linearly in order of the R position, the N position or the center position, and the D position or the B position, depending on the rotational position (rotational angle) of therotor member 80. Thus, it is possible to determine the swing position of theshift lever 10 in the shifting direction by monitoring the voltage output from thehall sensor 71. -
FIG. 16 is a chart showing an output waveform of thehall sensors 72. - As described above, as the
hall sensors 72 only need to determine the presence of themagnet 92, analog halls IC are used as thehall sensors 72. Further, the output waveform of thehall sensors 72 is shown low at the B position and the center position, and high at the R position, the D position, and the N position, depending on the rotational position (rotational angle) of thelever member 90. Thus, it is possible to determine the swing position of theshift lever 10 in the selecting direction. - Based on the combination of the swing positions of the
shift lever 10 in the shifting direction and the selecting direction determined by the output waveforms of thehall sensor 71 and thehall sensors 72 described above, the operational position of theshift lever 10 may be specified. - As described above, according to this embodiment, the shifting device may be configured to have a simplified structure, and be easily reduced in size and insusceptible to temperature change.
- Specifically, there are provided the
hall sensor 71 and thehall sensors 72 for converting the movement of theshift lever 10 both in the shifting direction and in the selecting direction into rotational movement both of therotor member 80 and thelever member 90, and for detecting the change in the due to rotation. With this, operation strokes of therotor member 80 and thelever member 90 may be achieved by a common driving mechanism, and thus the driving mechanism is integrated into a compact size. Further, as thehall sensor 71 and thehall sensors 72 are arranged on the same surface of thecircuit board 70, thecircuit board 70 may be used in common. Moreover, by providing thebase member 30 with a function for holding theshift lever 10 in a swingable manner and a function for holding thecircuit board 70, a hold function may be integrated. - Furthermore, the other end sections of the
rotor member 80 and thelever member 90 are respectively provided with theengagement pieces engagement grooves ball section 11 in the direction of the operational axis of theshift lever 10, and that follow movement of theshift lever 10 in one of the shifting direction and the selecting direction. With this, the driving mechanism with which therotor member 80 and thelever member 90 turn according to the swinging of theball section 11 that makes theshift lever 10 swingable may be realized with a simple structure. Further, by providing thebase member 30 with a function for pivotally-supporting therotor member 80 and thelever member 90, in addition to the function for holding theshift lever 10 in a swingable manner and the function for holding thecircuit board 70, a structure for holding the components may be integrated into thebase member 30. Thus, it is possible to simplify an overall structure and reduce its size. - Moreover, the detection target section of the
rotor member 80 is themagnet 82 provided for therotor member 80 such that both the N pole and the S pole face against thehall sensor 71. Thehall sensor 71 detects the rotational angle of themagnet 82 when therotor member 80 rotates according to swinging of theshift lever 10 in the shifting direction in a state in which themagnet 82 as the detection target section of therotor member 80 faces against thehall sensor 71. The shifting direction requires detection of important positions such as R (reverse), D (drive), N (neutral), and B (inertia brake), and therefore it is possible to provide a configuration with highly accurate detection by using, as thehall sensor 71, a linear hall IC for detecting the change in the angle of the magnetic flux due to the rotation of themagnet 82. - Further, the detection target section of the
lever member 90 is themagnet 92 provided for thelever member 90 so as to face against thehall sensors 72. Thehall sensors 72 detects whether or not themagnet 92 is at the facing position when thelever member 90 moves themagnet 92 as the detection target section of thelever member 90 either away from or closer to thehall sensors 72 according to swinging of theshift lever 10 in the selecting direction. The detection in the selecting direction is only between the neutral position and the select position, and the need for detection accuracy in this direction is less required compared to the shifting direction. Therefore, a simple structure capable of detecting the two positions may be employed. - Moreover, as a hall IC is used for either of the
hall sensors -

FIG. 27 is a sectional view of the shiftingdevice 2 taken along line indicated by an arrow K-K inFIG. 26 . - The shifting
device 2 includes ashift lever 210, thebezel 220, abase member 230, acasing 240, aguide case 250, aholder 260, acircuit board 270, arotor member 280, and alever member 290, and is mounted on a vehicle to shift a shift position of the vehicle. - Here, descriptions for components having the same functions as in the first embodiment described above shall be omitted if not necessary.
- The
shift lever 210 is a lever that can be operated by a driver, and held by thebase member 230 and theholder 260 in a manner swingable taking aball section 211 provided below (in a negative Z side) as a fulcrum. A direction in which theshift lever 210 is allowed to swing is restricted to a direction guided by aguide groove 252 provided for theguide case 250 that will be described later. Specifically, the direction in which theshift lever 210 is allowed to swing is restricted to the selecting direction in which an upper end (positive Z side end) of theshift lever 210 moves in the X direction, and the shifting direction in which the upper end (positive Z side end) of theshift lever 210 moves in the Y direction. - The
ball section 211 is integrated with theshift lever 210 by theshift lever 210 being inserted therethrough, and has a substantial spherical outer shape. Theball section 211 is provided withengagement grooves - With the
engagement groove 211 a, anengagement piece 281 that will be later described is slidably engaged. Further, with theengagement groove 211 b, anengagement piece 291 that will be later described is slidably engaged. - Moreover, to the
ball section 211, aclick member 212 is attached. As illustrated inFIG. 23 , theclick member 212 is provided with abias member 212 a and acontact pin 212 b. Theguide case 250 is provided withclick grooves 251 at positions corresponding to the swing positions of theshift lever 210. Thecontact pin 212 b provided at a tip end of theclick member 212 is in contact with theclick grooves 251 in a biased manner. When theshift lever 210 is operated, as theclick member 212 moves to an adjacent one of theclick grooves 251, it is possible to provide an appropriate sense of resistance (clicking feeling) in operation, and thus to improve operational feeling. Further, an operational position of theshift lever 210 may be held by the engagement between theclick member 212 and theclick grooves 251. - The
shift lever 210 also includes aguide cover 213 fitting with theshift lever 210 and provided so as to cover aconvex section 236 of thebase member 230 that will be later described. Theguide cover 213 is able to prevent a foreign matter from entering a throughhole 237 in theconvex section 236 from outside, and to guide the foreign matter to a peripheral section of theconvex section 236. - Other than an operating portion of the
shift lever 210, thebezel 220 is disposed on a surface closest to the driver, and a throughhole 221 through which theshift lever 210 is inserted is opening therein. Thebezel 220 is attached to thecasing 240 using ahook section 222 in a state in which theshift lever 210 is inserted through the throughhole 221. - The
base member 230 is contained in thecasing 240, and includes, in its substantial center, aconcave section 231 in which theball section 211 along with theholder 260 is held thus to hold theshift lever 210 in a swingable manner. As illustrated inFIG. 19 , theconcave section 231 opens downward (negative Z side) and to a side opposite of the circuit board 270 (positive X side). - For a plane on the negative X side of the
base member 230, there is provided a container section 233 a having acontainer opening 232 opening to the negative X side. Thecontainer section 233 holds and accommodates thecircuit board 270. As thecontainer opening 232 opens to a direction opposite of the opening of theconcave section 231, theconcave section 231 and thecontainer opening 232 maybe provided by asingle base member 230. Further, with thecasing 240 that will be later described, it is possible to easily provide a configuration in which theconcave section 231 and thecontainer opening 232 are fully covered. - The
base member 230 further includes a first pivotally-supportingsection 234 and a second pivotally-supportingsection 235 respectively pivotally-supporting therotor member 280 and thelever member 290 in a turnable manner. - The first pivotally-supporting
section 234 pivotally-supports ashaft section 280 a of therotor member 280 in a manner turnable following swinging of theshift lever 210 in the shifting direction. - The second pivotally-supporting
section 235 pivotally-supports ashaft section 290 a of thelever member 290 in a manner turnable following swinging of theshift lever 210 in the selecting direction. - Similarly to the first embodiment, the first pivotally-supporting
section 234 and the second pivotally-supportingsection 235 are provided in a shape in which cut-out openings are connected, each of the cut-out openings is an opening defining a shape of circle with a portion convex peripherally outward. Therotor member 280 and thelever member 290 are attached by positioning and inserting corresponding retaining sections of therotor member 280 and thelever member 290 respectively in the cut-out openings. - Further, the
base member 230 is provided with theconvex section 236 corresponding to theconcave section 231 on a side opposite of theconcave section 231. The throughhole 237 opens in theconvex section 236, and theshift lever 210 is disposed through the throughhole 237. Thebase member 230 is also provided with awall section 238 and adischarge section 239. - The
wall section 238 is provided in order to prevent the foreign matter guided by theguide cover 213 from moving outside thebase member 230, and projects to the positive Z side so as to cover all around an upper surface of the base member 230 (positive Z side surface). - The
discharge section 239 is a discharge outlet for discharging foreign matters provided in order to discharge the foreign matter guided to the upper surface of thebase member 230 by theguide cover 213 outside thebase member 230. In this embodiment, thedischarge section 239 opens so as to discharge the foreign matter downward. A discharge route further on is provided in a manner fully surrounded by thecasing 240, and a foreign matter may not come closer to thecircuit board 270 or the like. - In this embodiment, the
guide cover 213 covers the opening (the through hole 237) of thebase member 230 to prevent foreign matters such as water and dust from entering thebase member 230, and thewall section 238 and thedischarge section 239 guide the foreign matters outside thebase member 230. Thus, it is possible to ensure prevention of foreign matters from entering the shiftingdevice 2. - The
casing 240 includes a box section opening upward (positive Z side) so as to accommodate, along with thecircuit board 270, thebase member 230 to which thecircuit board 270 is attached. Further, casing 240 is in a box shape opening downward (negative Z side), where theguide case 250 is attached. - In a plane on an upward side (positive Z side) of the
guide case 250, theclick grooves 251 are provided at the positions corresponding to the positions of theclick member 212 that moves according to the shift position of theshift lever 210. Further, theguide groove 252 opens in theguide case 250, and theshift lever 210 is guided along theguide groove 252 to the plurality of operational positions. It should be noted that theguide groove 252 guides theshift lever 210 by contact, and theguide case 250 receives a load from theshift lever 210. Therefore, theguide case 250 is securely fixed to thecasing 240 using ashaft 253 and apush nut 254. - The
guide groove 252 guides theshift lever 210 to the plurality of operational positions. Specifically, similarly to the first embodiment, theguide groove 252 guides so as to restrict the swing range of theshift lever 210 to the shift positions including R position (reverse), D position (drive), N position (neutral), center position (the position illustrated inFIG. 1 , and B position (inertia brake). B position may be L position (Low), M position (manual), or the like. As used herein, a swing direction in which the tip end of theshift lever 210 moves in the Y direction is referred to as a shifting direction (first swing direction), and a swing direction in which the tip end of theshift lever 210 moves in the X direction is referred to as a selecting direction (second swing direction). - The
holder 260 is disposed at a position between thebase member 230 and thecasing 240, and together with theconcave section 231 of thebase member 230, holds theball section 211. - The
circuit board 270 is positioned within thecontainer section 233 of thebase member 230 so that its board surface is parallel with the YZ plane. Thecircuit board 270 is provided withhall sensors shift lever 210, and thehall sensors magnet 282 of therotor member 280 and amagnet 292 of thelever member 290. - The hall sensor (first detector member) 271 detects a rotational angle of the
magnet 282 when therotor member 280 rotates according to swinging of theshift lever 210 in the shifting direction in a state in which themagnet 282 faces against thehall sensor 271. As thehall sensor 271, a hall IC is used, capable of detecting a change in an angle of a magnetic flux due to rotation of themagnet 282, and outputting, as a detection signal, a voltage corresponding to the detected angle of the magnetic flux. - By the
hall sensor 271 detecting the rotational angle of themagnet 282, it is possible to determine whether theshift lever 210 has moved to the positive Y side or to the negative Y side in the shifting direction. - The hall sensors (second detector member) 272 detect whether or not the
magnet 292 is at a facing position when thelever member 290 moves themagnet 292 either away from or closer to thehall sensors 272 according to swinging of theshift lever 210 in the selecting direction. As thehall sensors 272 only need to determine the presence of themagnet 292, a hall IC that only outputs ON or OFF. - By the
hall sensors 272 detecting the position of themagnet 292, it is possible to determine whether theshift lever 210 has moved to the positive X side (either of R, N, and D) or to the negative X side (neutral position or B position) in the selecting direction. - Further, while the two
hall sensors 272 are provided in this embodiment so that it is possible to perform detection even if there is a trouble with one of the sensors, only onehall sensor 272 may be provided. - The rotor member (first detection target member) 280 is pivotally-supported by the
base member 230 in a turnable manner, and configured to turn following swinging of theshift lever 210 in the shifting direction. Therotor member 280 holds the magnet (detection target section) 282 at one end section (end section on the negative X side) in a manner rotatable in a plane vertical to the rotational axis of theshift lever 210 in the shifting direction (in the YZ plane). Themagnet 282 is provided for therotor member 280 such that both of its N pole and S pole face against thehall sensor 271. - To the other end section of the rotor member 280 (end section on the positive X side), the
engagement piece 281 is fixed. Theengagement piece 281 is engaged with theengagement groove 211 a provided in the direction of the operational axis of theshift lever 210, and rotates following movement of theshift lever 210 in the shifting direction. - The lever member (second detection target member) 290 is pivotally-supported by the
base member 230 in a turnable manner, and configured to turn following swinging of theshift lever 210 in the selecting direction. Thelever member 290 holds the magnet (detection target section) 292 at one end section of anarm section 290 b (end section on the negative X side) extending in a direction vertical to the rotational axis of the selecting direction. In this embodiment, themagnet 292 is provided for thelever member 290 so as to face against thehall sensors 272 when theshift lever 210 is in the center position. To the other end section of the lever member 290 (end section on the positive X side), theengagement piece 291 is fixed. Theengagement piece 291 is engaged with theengagement groove 211 b provided in the direction of the operational axis of theshift lever 210, and rotates following movement of theshift lever 210 in the selecting direction. - The
magnet 292 of this embodiment is configured such that its N pole is on a tip end side (a side closer to the hall sensors 272), and a side of the N pole (tip end side) is configured thinner than a side of an S pole so as to facilitate determination of a polar direction. It should be noted that if thehall sensors 272 are for S pole, the S pole may be on the tip end side of themagnet 292. - As described above, the
rotor member 280 and thelever member 290 are connected to theball section 211 respectively via theengagement piece 281 and theengagement piece 291, and therefore therotor member 280 and thelever member 290 are able to rotate independently from each other without hindering the movement of theshift lever 210 in the shifting direction and the selecting direction. - As described above, according to this embodiment, while basically employing the same configuration as that in the first embodiment, the

- The
shift lever 310 is a lever that can be operated by a driver, and held by thebase member 330 and thecasing 340 in a manner swingable taking aball section 311 provided below (in a negative Z side) as a fulcrum. A direction in which theshift lever 310 is allowed to swing is restricted to a direction guided by aguide groove 352 c provided for adetent member 352 that will be described later. Specifically, the direction in which theshift lever 310 is allowed to swing is restricted to the selecting direction in which an upper end (positive Z side end) of theshift lever 310 moves in the X direction, and the shifting direction in which the upper end (positive Z side end) of theshift lever 310 moves in the Y direction. - The
ball section 311 is integrated with theshift lever 310 by theshift lever 310 being inserted therethrough, and has a substantial spherical outer shape as a whole, although the outer shape includes holes for lightening. Theball section 311 is provided withengagement grooves - With the

Accordingly, it is possible to provide an appropriate sense of resistance (clicking feeling) in operation, and thus to improve operational feeling. Further, the operational position of theshift lever 310 may be held by the engagement between thecontact pin 312 b and theclick groove - Moreover, a part of the
shift lever 310 extending down (negative Z side) below theball section 311 is provided with a lever-side contact section 311 c projecting to the negative X side. The lever-side contact section 311 c is provided at a position at which the lever-side contact section 311 c may be brought in contact with acontact section 356 b of acam section 356 a that will be later described. - Other than an operating portion of the
shift lever 310, thebezel 320 is disposed on a surface closest to the driver, and a throughhole 321 through which theshift lever 310 is inserted is opening therein. Thebezel 320 is attached to thecasing 340 in a state in which theshift lever 310 is inserted through the throughhole 321. - The
base member 330 holds theball section 311 in its substantial center, and thus holds theshift lever 310 in a swingable manner. The portion that holds theball section 311 is provided so as to open to the negative Z side and the positive X side. - Further, the
base member 330 includes acontainer section 333 for holding thecircuit board 370. Thecontainer section 333 is provided for a negative X side surface of thebase member 330 so as to open to the negative X side. As thecontainer section 333 opens to a direction opposite of the opening of the portion that holds theball section 311, the portion that holds theball section 311 and thecontainer section 333 may be provided by asingle base member 330. Further, with thecasing 340 that will be later described, it is possible to easily provide a configuration in which theconcave section 31 and thecontainer opening 32 are fully covered. - Further, the
base member 330 pivotally-supports therotor member 380 and thelever member 390 in a turnable manner. - The
casing 340 is in a box shape opening upward (positive Z side) so as to accommodate, along with thecircuit board 370, thebase member 330 to which thecircuit board 370 is attached. It should be noted that the structure of thecasing 340 may not be limited to a structure having an opening as in this embodiment, and may be altered appropriately. - The shift
lever restricting mechanism 350 includes thegear base member 351, thedetent member 352, aworm 353, atransmission gear 354, ashaft 355, the restrictingmember 356, a restrictinggear 357, and a motor M. - The
gear base member 351 is provided at a lower section (negative Z side) of the shiftingdevice 3, and fixed to thebase member 330. Thegear base member 351 is provided with a main part of the shiftlever restricting mechanism 350. - The
detent member 352 is attached to thegear base member 351, and provided with theclick grooves guide groove 352 c. When theshift lever 310 is operated, theclick grooves click member 312 described above. Theguide groove 352 c guides theshift lever 310 to the plurality of operational positions. Specifically, as illustrated inFIG. 29 , theguide groove 352 c guides so as to restrict the swing range of theshift lever 310 to the shift positions including R position (reverse), D position (drive), H position (home position, neutral position), M position (manual operation position), positive position (shift up), and negative position (shift down). As used herein, a swing direction in which the tip end of theshift lever 310 moves in the Y direction is referred to as a shifting direction (first swing direction), and a swing direction in which the tip end of theshift lever 310 moves in the X direction is referred to as a selecting direction (second swing direction). - The
worm 353 is provided so as to rotate together with an output shaft of the motor M. Theworm 353 meshes with aworm wheel 354 a of thetransmission gear 354. - The
transmission gear 354 includes theworm wheel 354 a and agear section 354 b, and is provided rotatably centering agear shaft 354 c. - As described above, the
worm wheel 354 a meshes with theworm 353, and thegear section 354 b meshes with the restrictinggear 357. - The
gear shaft 354 c extends in a direction parallel with a direction in which theshift lever 310 in the home position extends (direction of a Z axis). - The shaft (rotational shaft) 355 extends in the same direction as the
gear shaft 354 c, that is, parallelly with the direction in which theshift lever 310 in the home position extends (direction of the Z axis). Theshaft 355 is provided with the restrictingmember 356 and the restrictinggear 357 such that the restrictingmember 356 and the restrictinggear 357 rotate together with theshaft 355. Theshaft 355 is constituted as a magnetic body,magnets gear 357 using a pulling force due to a magnetic force to theshaft 355. - The restricting
member 356 includes thecam section 356 a, thecontact section 356 b, and themagnets shaft 355 and the restrictinggear 357. - The
cam section 356 a is an arc-like cam, eccentric with respect to a rotational center of theshaft 355. An arc-like surface of the cam section constitutes thecontact section 356 b that is brought into contact with the lever-side contact section 311 c of theshift lever 310. - When the restricting
member 356 rotates into the shift-restricting position, thecontact section 356 b is brought into contact with of the lever-side contact section 311 c of theshift lever 310, and releases a holding state of theshift lever 310 by the shift lever holding mechanism (theclick member 312 and the detent member 352) to return theshift lever 310 to the H position. Further, when the restrictingmember 356 is in the shift-restricting position, movement of theshift lever 310 to the M position is restricted by the lever-side contact section 311 c being brought into contact with thecontact section 356 b. - After the
cam section 356 a and the restrictinggear 357 are attached to theshaft 355, the magnets (detection target section) 356 c and 356 d are respectively inserted into two through holes opening in the restrictinggear 357, and attached by the pulling force of themagnets shaft 355. Themagnet 356 c and themagnet 356 d are attached such that their polarities exposed from the restrictinggear 357 are different from each other. As themagnets member 356, the rotational position of the restrictingmember 356 may be detected based on the magnetic polarity detected by ahall sensor 373 that will be described later. - The restricting gear (third detection target member) 357 is attached to the
shaft 355, and rotates together with theshaft 355 and thecam section 356 a. The restrictinggear 357 meshes with thegear section 354 b of thetransmission gear 354. Accordingly, as the motor M rotates, the restrictinggear 357 also rotates to rotate the restrictingmember 356. Further, as described above, the magnets (detection target section) 356 c are 356 d are attached to the restrictinggear 357. - A
control section 358 refers to a result of the detection by thehall sensor 373, and commands a microcomputer that is not shown but mounted on thecircuit board 370 to change the position of the restrictingmember 356 between the shift-restricting position and the released position. The microcomputer controls the motor M. - The motor M is an actuator that constitutes a drive source for driving the shift
lever restricting mechanism 350. As described above, driving of the motor M is controlled by thecontrol section 358 via the microcomputer mounted on thecircuit board 370. - Based on the above configuration, the shift
lever restricting mechanism 350 restricts movement of theshift lever 310 to the M position under a predetermined condition. - The
circuit board 370 is positioned within thecontainer section 333 of thebase member 330 so that its board surface is parallel with the YZ plane. Thecircuit board 370 is provided withhall sensors shift lever 310, and thehall sensors magnet 382 of therotor member 380 and amagnet 392 of 3 thelever member 390. - The hall sensor (first detector member) 371 detects a rotational angle of the
magnet 382 when therotor member 380 rotates according to swinging of theshift lever 310 in the shifting direction in a state in which themagnet 382 faces against thehall sensor 371. As thehall sensor 371, a hall IC, capable of detecting a change in an angle of a magnetic flux due to rotation of themagnet 382, and outputting, as a detection signal, a voltage corresponding to the detected angle of the magnetic flux, is used. - By the
hall sensor 371 detecting the rotational angle of themagnet 382, it is possible to determine whether theshift lever 310 has moved to the positive Y side or to the negative Y side in the shifting direction. - The hall sensor (second detector member) 372 is configured by two pairs of the
hall sensors hall sensor 372 detects a moving position of themagnet 392 by thelever member 390 moving themagnet 392 away from and closer to the two pairs of thehall sensors shift lever 310 in the selecting direction. Thehall sensor 372 a is positioned on the positive Z side, and detects that themagnet 392 moves to the positive Z direction as theshift lever 310 is operated to the positive X side (M position). On the other hand, thehall sensor 372 b is positioned on the negative Z side, and detects that themagnet 392 moves to the negative Z direction as theshift lever 310 is operated to the negative X side (R position or D position). When theshift lever 310 is in the H position, theshift lever 310 is positioned between the hall sensors 392 a and 392 b, and is not detected by either sensor. - By the
hall sensor 372 detecting the position of themagnet 392, it is possible to determine whether theshift lever 310 has moved to the negative X side (R position or D position) in the selecting direction, the H position, or the positive X side (M position). - Further, the
circuit board 370 is provided with the hall sensor (third detector member) 373 on a surface of thecircuit board 370 that is the same as the surface on which thehall sensors hall sensor 373 is disposed at a position at which thehall sensor 373 is allowed to face against the magnets (detection target section) 356 c and 356 d of the restricting gear (third detection target member) 357. - The hall sensor (third detector member) 373 is configured by a hall IC that is reactive to both N pole and S pole and configured to output different signals depending on the detected magnetic polarity, and detects the rotational position of the restricting
member 356. - The rotor member (first detection target member) 380 is pivotally-supported by the
base member 330 in a turnable manner, and configured to turn following swinging of theshift lever 310 in the shifting direction. Therotor member 380 holds the magnet (detection target section) 382 at one end section (end section on the negative X side) in a manner rotatable in a plane vertical to the rotational axis of theshift lever 310 in the shifting direction (in the YZ plane). Themagnet 382 is provided for therotor member 380 such that both of its N pole and S pole face against thehall sensor 371. - To the other end section of the rotor member 380 (end section on the positive X side), the
engagement piece 381 is fixed. Theengagement piece 381 is engaged with theengagement groove 311 a provided in the direction of the operational axis of theshift lever 310, and rotates following movement of theshift lever 310 in the shifting direction. - The lever member (second detection target member) 390 is pivotally-supported by the
base member 330 in a turnable manner, and configured to turn following swinging of theshift lever 310 in the selecting direction. Thelever member 390 holds the magnet (detection target section) 392 at one end section of an arm section 390 b (end section on the negative X side) extending in a direction vertical to the rotational axis of the selecting direction. In this embodiment, themagnet 392 is provided for thelever member 390 so as to face against thehall sensor 372 when theshift lever 310 is in the H position. To the other end section of the lever member 390 (end section on the positive X side), theengagement piece 391 is fixed. Theengagement piece 391 is engaged with theengagement groove 311 b provided in the direction of the operational axis of theshift lever 310, and rotates following movement of theshift lever 310 in the selecting direction. - As described above, the
rotor member 380 and thelever member 390 are connected to theball section 311 respectively via theengagement piece 381 and theengagement piece 391, and therefore therotor member 380 and thelever member 390 are able to rotate independently from each other without hindering the movement of theshift lever 310 in the shifting direction and the selecting direction. - Here, an operation in the M position to which control by the
control section 358 is related. - As the
shift lever 310 moves from the H position to the M position, theshift lever 310 is held in the M position by theclick member 312 and thedetent member 352 constituting the shift lever holding mechanism. - In this state, the
shift lever 310 becomes operable in the shifting direction, and is shifted up when moved to the positive direction and shifted down when moved to the negative direction. - When the driver turns an engine off in the manual state, that is, while the
shift lever 310 is in the M position, thehall sensor 372 detects the position of themagnet 392. If theshift lever 310 is determined to remain in the M position (manual operational position), thecontrol section 358 actuates the motor M to rotate the restrictingmember 356. Then, as thecontact section 356 b of thecam section 356 a is brought into contact with the lever-side contact section 311 c of theshift lever 310, theshift lever 310 is pushed to the H position, and theshift lever 310 returns to the H position. - If the
hall sensor 373 detects that thecam section 356 a reaches the restricting position, thecontrol section 358 stops driving of the motor M, and stops the restrictingmember 356 at the position at which thecontact section 356 b faces against the lever-side contact section 311 c. - With this, movement to the M position is restricted by the
contact section 356 b of the restrictingmember 356 unless the engine starts again and theshift lever 310 is moved to the driving position (D) or the reverse position (R). - When it is detected that the
shift lever 310 has been moved to the D position (driving position) or to the R position (reverse position) after the engine starts, thecontrol section 358 again actuates the motor M to move thecontact section 356 b to a position at which thecontact section 356 b does not face against the lever-side contact section 311 c. With this, the restriction of the movement of theshift lever 310 to the M position is released, and theshift lever 310 is allowed to move to the M position. - As described above, according to the third embodiment, the rotational center shaft (the shaft 355) of the restricting
member 356 is disposed so as to be parallel to theshift lever 310 in the H position. With this, the hall sensor (third detector member) 373 for detecting the position of the restrictingmember 356 and the hall sensor (first detector member) 371 and the hall sensor (second detector member) 372 for detecting the swing direction of theshift lever 310 may be mounted on the same surface of thecircuit board 370. Thus, with the shiftingdevice 3 according to this embodiment, in addition to the effects similarly to the first embodiment, it is possible to determine whether or not the movement of theshift lever 310 is restricted, to cause theshift lever 310 automatically return to the H position, and to reduce its size even with the above further functions. cl Modified Example - The present invention is not limited to the embodiments described above, and it is possible to make various modifications and alterations, which are also included within the scope of the present invention.
- For example, in the second embodiment, the example in which the
discharge section 239 guides and discharges a foreign matter downward and outside through thecasing 240. The present invention is not limited to such an example, and the discharge section may be configured so as to discharge a foreign matter outside the casing, and the discharge route for discharging foreign matters may be altered as appropriate. - While the first embodiment to the third embodiment as well as the modified example maybe combined as appropriate, detailed description of such combinations are omitted. Further, the present invention is not limited to the embodiments described above.
