Description

  The present invention relates to a lever operation position determination device for a transmission operation lever that detects an operation position of the operation lever when the transmission operation lever is operated.

  2. Description of the Related Art Conventionally, in vehicles such as automobiles, automatic vehicles that travel with an automatic transmission that automatically switches a gear speed ratio according to speed and engine speed have become widespread. The driver's seat of this type of automatic vehicle is provided with a select lever that is operated when the range position of the automatic transmission is switched. The select lever can be operated to a plurality of range positions such as a P position, an N position, a D position, and an R position, for example, and a floor shift type located on the center console is generally widely used. This type of select lever is provided with a lever position detecting device for detecting which range position the select lever is in, and an example of this device is disclosed in Patent Document 1 and the like.

  FIG. 8 shows a general lever position detection device. A housing 82 of a lever position detection device 81 is attached to the vehicle body. A select lever 83 serving as an operation point at the time of switching the range position is attached to the housing 82 so as to be rotatable about a rotation shaft 84 located near the base end thereof. For this reason, when the range position of the select lever 83 is switched, the range lever switching operation is permitted by rotating the select lever 83.

Further, when the position detection type of the lever position detection device 81 is a magnetic type, a lever position detection system substrate 85 is attached inside the housing 82 at a position facing the base end of the select lever 83. A magnetoresistive element 86 (a Hall element is also possible) is attached to the substrate 85 at a position corresponding to each range position. Further, a magnet 87 is attached to the base end position of the select lever 83 at a position facing the magnetoresistive element 86. In the magnetic lever position detecting device 81, the magnetoresistive elements 86 facing the magnets 87 are set according to the range position of the select lever 83, and any of the plurality of magnetoresistive elements 86, 86. The range position of the select lever 83 is detected by observing whether the magnetic field is detected.

  However, with this type of select lever 83, in order to ensure a reliable switching operation at the time of the range position switching operation, the lever operation when switching the select lever 83 from one range position to the adjacent range position is performed. The amount La needs a certain distance. Therefore, the general select lever 83 has a rotation shaft 84 at a position closer to the base end thereof, so that the rotation operation amount on the distal end side of the select lever 83, that is, the lever operation amount La between adjacent range positions. Is secured.

  However, if the rotation shaft 84 of the select lever 83 is arranged closer to the lever base end position, the rotation operation amount on the lever distal end side can be widened. On the contrary, the rotation operation amount on the lever base end side is relatively large. It will become narrower. For this reason, the magnet 87 arranged at the base end position of the select lever 83 has a narrow magnet movement amount Lb at the time of the range position switching operation. If the magnet movement amount Lb is too small in this way, the magnet 87 is Since the two magnetoresistive elements 86 and 86 are affected at the same time, it is necessary to make the magnet movement amount Lb as wide as possible for reliable range position detection. In this case, in order to increase the magnet movement amount Lb, the protrusion amount Lc from the rotation shaft 84 to the lever base end may be increased. However, when this structure is adopted, the select lever 83 becomes longer correspondingly. There was a concern that led to an increase in the size of the device.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a lever operation position detecting device for a transmission operation lever that can keep the size in the lever length direction as small as possible and can secure the amount of movement of the detection element of the lever operation position detection system. There is.

In order to solve the above-mentioned problems, the present invention is used as an input system that is provided as an input system when operating a transmission of a vehicle and that is allowed to operate by rotating during the operation. In a lever operation position determination device for a transmission operation lever that determines an operation position of the operation lever when the operation lever is rotated, a detection unit that detects the operation position of the operation lever and a detected unit One of them is attached as a lever-side detection system to the operation lever that is in an installed state standing on the detection plane of the detection unit and the detected portion, and the other of these two is for the transmission It is attached to a support member that rotatably supports the operation lever as a support side detection system, and the lever side detection system is opposed to the support side detection system when the operation lever is rotated. Includes an amplification mechanism for amplifying the link structure the movement amount,
In the amplifying mechanism, a plurality of links rotatable about the base end are arranged so as to cross each other, and the operation lever that can be rotated in a plurality of different operation directions on the detection plane is operated in one direction. Each of the operation directions by connecting the operation lever to the link so that one of the plurality of links is selectively rotated, and attaching the lever side detection system to the tip side of each link. The main point is to amplify the amount of movement .

  According to this configuration, when the operation lever is rotated, the positional relationship between the detection unit and the detected unit is switched, and the operation position of the operation lever is based on the detection value output by the detection unit at this time. Is determined. By the way, in order to reliably detect the operation position when the operation lever is rotated from one operation position to the adjacent operation position, the detected part is provided with a plurality of detection parts when the operation lever takes one operation position. It is necessary to increase the amount of movement of the lever side detection system so as not to affect the state. Therefore, in this configuration, an amplification mechanism is provided that amplifies the input operation amount when the operation lever is turned and outputs it as the movement amount of the lever side detection system. It is possible to cause the detection unit and the detected unit to take the arrangement positional relationship necessary for detecting the operation position. If this type of amplification mechanism is provided to amplify the amount of movement of the lever-side detection system, the length of the operation lever can be short, and the apparatus can be downsized as the operation lever is reduced in size.

  By the way, for example, if the detection plane of the detection unit and the detection target portion is mounted parallel to the operation lever, the operation lever is arranged in parallel with the substrate. In this case, since the operating lever must always be longer than the substrate, the operating lever in this case is affected by the size (width) of the substrate, and the length of the operating lever is relatively long. Concerns arise. However, this configuration takes the mounting state in which the operating lever is erected with respect to the detection plane of the lever operating position detection system, so that the length of the operating lever is not affected by the board, so the length of the operating lever is shortened. It becomes possible to do. Therefore, from this point of view, the length of the operation lever in the lever axial direction can be shortened.

  According to this configuration, even if the operation lever has a structure that can rotate in a plurality of directions as a kind of operation lever, it is possible to amplify the amount of movement of the lever side detection system in each operation direction. Become.

In the present invention, the amplifying mechanism includes a protrusion formed on a proximal end side of the operation lever, a connecting member that is engaged with the operation lever while the protrusion is engaged, and a shaft portion along the detection plane. fulcrum attached to said coupling member in a rotatable state, together with the connecting member is passed through the long hole of its own, the lever-side detection position opposite from said shaft portion across the slot The gist of the invention is that the system includes a plurality of the links to which a system is attached.

  According to this configuration, since this type of link mechanism has a simple structure as a mechanism for amplifying and outputting the input operation amount, the movement amount of the lever side detection system is amplified using the link mechanism as in this configuration. If the structure is adopted, it is possible to amplify the amount of movement of the lever side detection system when the operation lever is turned with a structure as simple as possible.

  According to the present invention, the amount of movement of the detection element of the lever operation position detection system can be secured while keeping the size in the lever length direction as low as possible.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a lever operation position detection device for a transmission operation lever embodying the present invention will be described below with reference to FIGS.
As shown in FIG. 1, an automatic vehicle is provided with a select lever device 2 that is operated when switching an operation state of an automatic transmission 1 (transmission: see FIG. 6). The select lever device 2 of the present example has a shift-by-wire structure in which a select lever 3 that is an operation portion at the time of range position switching is electrically connected to the automatic transmission 1 instead of mechanically. The select lever device 2 is provided with a box-shaped case 4 as an assembly location on the vehicle body. The select lever device 2 of this example is not limited to the floor type arranged at the center console in the vehicle, but adopts, for example, a column type arranged at the steering column or an instrument panel type arranged at the center cluster. Also good. The select lever 3 corresponds to an operation lever, and the case 4 corresponds to a support member.

  A substantially rod-shaped select lever 3 is attached to the case 4 so as to be rotatable with respect to the case 4 along the vehicle traveling direction and the vehicle width direction (that is, the front-rear direction and the left-right direction). The select lever 3 is in an attached state in which the tip protrudes to the outside through a substantially H-shaped guide groove 6 formed in the panel 5 corresponding to the upper wall of the case 4. The select lever 3 of this example can be operated in the vehicle advancing direction (hereinafter referred to as the shift direction) in the first groove 6a and the second groove 6b extending in the vehicle advancing direction in the guide groove 6, By operating the connecting groove 6c for connecting the 6a and the second groove 6b in the vehicle width direction (hereinafter referred to as the select direction), the first groove 6a and the second groove 6b can be moved. The select lever 3 has a front end position set to the parking position (P position) in the first groove 6a and a rear end position set to the regenerative brake position (B position). In the second lever 6b, the select lever 3 has a front end position set to a reverse position (R position), an intermediate position set to a neutral position (N position), and a rear end position set to a drive position (D position). Is set.

  As shown in FIGS. 2 and 3, a holding member 8 that functions as a support component for the select lever 3 is disposed in the select direction (with respect to the case main body 7) in the case main body 7 constituting the main body of the case 4. It is attached so as to be rotatable along the direction of arrow Ra in FIG. The holding member 8 has a select shaft portion 9 extending in the shift direction, and the select shaft portion 9 is in an attached state in which the select shaft portion 9 is rotatably inserted into the pair of hole portions 10 of the case main body portion 7. An insertion hole 11 extending in the select direction is provided at the center position of the holding member 8.

  Further, the select lever 3 is attached to the holding member 8 so as to be rotatable with respect to the holding member 8 along the shift direction (the direction of the arrow Rb in FIG. 2). As this mounting structure, an annular lever mounting portion 12 is formed at the base end of the select lever 3, and holes 13 are respectively formed through a pair of side walls of the lever mounting portion 12. The select lever 3 passes the shift shaft portion 14 that is orthogonal to the select shaft portion 9 through the pair of holes 13 of the lever mounting portion 12 and the insertion hole 11 of the holding member 8, and the shaft tip is By being stopped by the washer 15, the holding member 8 is rotatably attached.

  Further, when the select lever device 2 is a momentary type, the select lever 3 that has been operated to switch the range position in the select direction is placed between the case 4 and the holding member 8, for example, at an intermediate position between the P position and the B position. Assuming the neutral position, a first urging member 16 that automatically returns to the neutral position is attached. As the first urging member 16, for example, a torsion spring spring or the like is used, and the first urging member 16 is in an attached state wound around the select shaft portion 9. In addition, a second urging member 17 that automatically returns the select lever 3 that has been operated to switch the range position in the shift direction to the neutral position is mounted between the holding member 8 and the lever mounting portion 12 as a similar function. . As the second urging member, for example, a torsion spring or the like is used, and the attached state is wound around the shift shaft portion 14.

  Therefore, when the select lever 3 is operated in the shift direction starting from the neutral position, the select lever 3 rotates in the shift direction with respect to the holding member 8 with the shift shaft portion 14 as a fulcrum. Lever operation is allowed. Further, when the select lever 3 is operated in the select direction starting from the neutral position, the select lever 3 is integrated with the holding member 8 to rotate in the select direction with respect to the case 4 with the select shaft portion 9 as a fulcrum. By doing so, lever operation in the select direction is allowed. After the selector lever 3 is operated to switch the range position, the first urging member 16 and the second urging member 17 function to cause the select lever 3 to automatically return to the neutral position.

  As shown in FIGS. 3 and 4, the select lever device 2 is provided with a lever position detection device 18 that determines the current range position when the select lever 3 is operated to switch the range position. The lever position detection device 18 of this example is a magnetic type that determines the range position of the select lever 3 by magnetic detection, and specifically, a plurality of (two in this example) magnets 19 and 20 on the select lever 3 side. And attach a plurality of (six in this example) magnetic detection elements 21 to 25 to the case 4 side and see which of these magnetic detection elements 21 to 25 detects the magnetic field of the magnets 19 and 20. Thus, the range position of the select lever 3 is determined. The magnets 19 and 20 correspond to the detected part (lever side detection system), and the magnetic detection elements 21 to 25 correspond to the detection part (support side detection system).

  A detection unit 26 of the magnetic lever position detection device 18 is attached to the bottom of the case body 7. The detection unit 26 has a structure in which a substrate 29 is sandwiched between an upper cover 27 and a lower cover 28, and is fixed at a plurality of locations (two locations in this example) by overlapping them and passing one bolt (not shown). By doing so, it is fixedly attached to the case body 7. A connector 30 is formed as a connection port through which the detection signal of the lever position detection device 18 can be taken out at the back surface position of the substrate 29 at the side surface position of the detection unit 26.

  The magnetic lever position detecting device 18 of this example is provided with a link mechanism 31 that amplifies the magnet movement amount Lk (see FIG. 5) when the select lever 3 is operated to switch the range position by the link structure. The link mechanism 31 of the present example is configured so that when the select lever 3 is operated to switch the range position, the select lever 3 rotates in a vertical plane (XZ plane rotation and YZ plane rotation in FIGS. 3 and 4). This is a mechanism that amplifies the magnet movement amount Lk by converting the plane rotation motion into a plane rotation motion of a horizontal plane rotation (XY plane rotation in FIGS. 3 and 4) in a direction orthogonal to this. The link mechanism 31 corresponds to an amplification mechanism, and the XY plane corresponds to a detection plane.

  The link mechanism 31 will be described in detail below. On the base end face of the select lever 3, a protrusion 32 that functions as a sphere fulcrum is formed by protruding the tip portion into a spherical shape. A pair of links 34 and 35 arranged in directions orthogonal to each other are attached to the protrusion 32 via a slider 33 which is an intermediate part. The links 34 and 35 are arranged in an overlapping state, and the longitudinal direction of the links 34 and 35 is substantially orthogonal to the lever axis direction of the select lever 3 (the one-dot chain line Lp in FIG. 4). Taking the direction. In this example, the links 34 and 35 are links that move in synchronization with the select lever 3 being operated in the select direction as the select side link 34, and this link is operated when the select lever 3 is operated in the shift direction. A link that moves in synchronization with each other is referred to as a shift side link 35. The slider 33 corresponds to a connecting member.

  The select side link 34 has a flat plate shape that extends along the shift direction of the select lever 3, and one end of the select side link 34 is attached to the upper cover 27 of the detection unit 26 via a select side support shaft 36. . A select-side long hole 37 through which the slider 33 passes is formed in the center of the select-side link 34. The select side long hole 37 pushes the select side link 34 while moving the slider 33 in its own hole when the select lever 3 is vertically rotated in the select direction (YZ plane rotating motion in FIG. 5). By allowing the link 34 to move, the link 34 is allowed to move in a horizontal plane rotation direction (XY plane rotation movement in FIG. 5) in the substantially orthogonal direction by the rotation movement of the select lever 3. Further, at the other end of the select side link 34, for example, a select side magnet 19 having a cylindrical shape is integrally formed with the link member by insert molding. At a position where the tip end of the select side link 34 is located at the edge of the upper cover 27, a select side link pressing portion 38 that presses the select side link 34 from above while allowing the rotational movement of the select side link 34 is provided. Is formed.

  The shift side link 35 has a flat plate shape extending in the select direction of the select lever 3 so as to be orthogonal to the select side link 34, and one end of the shift side link 35 is rotated to the upper cover 27 of the detection unit 26 via the shift side support shaft 39. It is mounted movably. A shift-side long hole 40 through which the slider 33 can be passed along with the select-side long hole 37 is provided at the center of the shift-side link 35. This shift side long hole 40 also has the same function as the select side long hole 37. Further, for example, a columnar shift side magnet 20 is integrally formed on the link member at the other end of the shift side link 35 by insert molding. At a position where the tip of the shift side link 35 is located at the edge of the upper cover 27, a shift side link pressing portion 41 that presses the shift side link 35 from the top while allowing the rotational movement of the shift side link 35 is provided. Is formed. The support shafts 36 and 39 correspond to shaft portions.

  A hole portion 42 into which the protrusion 32 of the select lever 3 can be engaged is recessed in the surface of the slider 33 facing the select lever 3. Since the slider 33 is a component that converts the arc motion of the select lever 3 into the plane rotation motion of the links 34 and 35, the hole portion 42 is formed deep with a margin in the vertical direction. That is, when the select lever 3 is operated, the base end of the select lever 3 moves to draw an arc locus. At this time, the protrusion 32 of the select lever 3 moves in the hole portion 42 of the slider 33, so that the slider 33 converts the arc movement of the select lever 3 into the plane rotation movement of the links 34 and 35 to allow the plane rotation of the links 34 and 35. A flange 43 that protrudes from the elongated holes 37 and 40 of the links 34 and 35 protrudes in an annular shape on the bottom periphery of the slider 33.

  The magnetic detection elements 21 to 25 are composed of, for example, a Hall element or a magnetoresistive element, and are mounted on the upper surface of the substrate 29. These magnetic detection elements 21 to 25 are divided into functions of a detection element group for viewing the range position of the select lever 3 in the shift direction and a detection element group for viewing the range position of the select lever 3 in the select direction. In this example, in these magnetic detection elements 21 to 25, 24 and 25 existing at positions facing the select-side magnet 19 are a selection detection element group, and 21 to 21 existing at positions facing the shift-side magnet 20. Reference numeral 23 denotes a shift detection element group. Further, the upper case 4 is provided with a conduction hole 44 through which a member is integrally removed at a position where the magnets 19 and 20 and the magnetic detection elements 21 to 25 face each other.

  As shown in FIG. 6, the magnetic lever position detection device 18 is provided with a shift ECU 45 as a control unit for detecting the operation position. Magnetic detection elements 21 to 25 are connected to the input side of the shift ECU 45, and the automatic transmission 1 is connected to the output side. The shift ECU 45 determines the range position of the select lever 3 based on the detection signals acquired by the magnetic detection elements 21 to 25, and the gear of the automatic transmission 1 so that the automatic transmission 1 takes the gear position corresponding to the range position. The position is switched and controlled.

Next, the operation of the magnetic lever position detector 18 configured as described above will be described.
First, when the select lever 3 is initially positioned at the neutral position, the shift-side magnet 20 at this time takes a position facing the second magnetic detection element 22, and the select-side magnet 19 faces the fourth magnetic detection element 24. Take position. Accordingly, the second magnetic detection element 22 and the fourth magnetic detection element 24 output H level signals, and the first magnetic detection element 21, the third magnetic detection element 23, and the fifth magnetic detection element 25 other than these output L level signals. Is output. The shift ECU 45 has an L level from the first magnetic detection element 21, an H level from the second magnetic detection element 22, an L level from the third magnetic detection element 23, an H level from the fourth magnetic detection element 24, and a fifth magnetic detection element 25. Since the L-level detection signal is input from this, it is determined that the select lever 3 is positioned at the neutral position by this signal input, and the automatic transmission 1 is caused to perform an operation corresponding to the neutral position.

  Assuming that the range position switching operation is performed from the neutral position to the P position of the select lever 3, the lever operation is accompanied by the turning operation of the select lever 3 in the pushing direction (arrow Rb1 direction in FIG. 3). Then, the slider 33 moves in the shift side long hole 40 and pushes the shift side link 35 to the drawing side (arrow Kb direction in FIG. 3), and the shift side link 35 rotates in the clockwise direction (arrow Rc1 direction in FIG. 3). As a result, the shift-side magnet 20 faces the first magnetic detection element 21. At this time, the select side link 34 has its own select side long hole 37 in a direction substantially parallel to the moving direction of the slider 33, so that the slider 33 moves along the select side long hole 37 at the time of lever operation at this time. It will move. Therefore, even if the lever operation is performed, the select side link 34 does not rotate largely on the plane, and the select side magnet 19 maintains the state facing the fourth magnetic detection element 24.

  By the way, as a feature of the link mechanism 31 of this example, as shown in FIG. 7, the link 34 (35) moves in a plane rotating from the link intermediate position to the fulcrum Pb with the link intermediate position as the action point Pa. The movement amount X1 of the action point Pc at the end of the link during the plane rotation is larger than the movement amount X2 of the action point Pa located at the link intermediate point. Therefore, using this link principle, the structure of this example is used in which the link mechanism 31 is interposed at the base end position of the select lever 3 (ie, lever operation output destination) and the magnet 19 (20) is attached to the link tip. In this case, for example, the magnet movement amount Lk becomes larger than when the magnet 19 (20) is attached to the base end position of the select lever 3.

  When the select lever 3 is positioned at the P position, the shift-side magnet 20 at this time takes a position facing the first magnetic detection element 21, and the select-side magnet 19 maintains a state facing the fourth magnetic detection element 24. . Therefore, the shift ECU 45 has the H level from the first magnetic detection element 21, the L level from the second magnetic detection element 22, the L level from the third magnetic detection element 23, the H level from the fourth magnetic detection element 24, and the fifth magnetic detection. Since an L level detection signal is input from the element, it is determined that the select lever is at the P position by this signal input, and the automatic transmission 1 is caused to perform an operation corresponding to the P position.

  Subsequently, if the selector lever 3 is operated to change the range position from the neutral position to the N position, the selector lever 3 is also rotated in the right direction of the vehicle width (in the direction of the arrow Ra1 in FIG. 3). The slider 33 moves in the select side long hole 37 and pushes the select side link 34 toward the pushing side (in the direction of the arrow Ka in FIG. 3) so that the select side link 34 is counterclockwise ( 3, the select-side magnet 19 faces the fifth magnetic detection element 25. At this time, the shift side link 35 has its own shift side long hole 40 in a direction substantially parallel to the moving direction of the slider 33. Therefore, the slider 33 moves along the shift side long hole 40 during the lever operation at this time. It will move. Accordingly, even if the lever operation is performed, the shift side link 35 does not rotate largely on the plane, and the shift side magnet 20 maintains the state facing the second magnetic detection element 22.

  For this reason, the magnets 19 and 20 that work for detecting the lever position are the same as when the select lever 3 is operated from the neutral position to the B position when the select lever 3 is operated from the neutral position to the N position. The link mechanism 31 amplifies the magnet movement amount Lk and changes its position. Therefore, even when the select lever 3 is operated from the neutral position to the N position, the select-side magnet 19 takes a large magnet movement amount Lk and moves to the destination. Although not described in detail, the magnets 19 and 20 move in the same manner when the select lever 3 is operated to switch the range position from the neutral position to the B position, the R position, and the D position.

  Therefore, in this example, a link mechanism 31 capable of amplifying and outputting the input operation amount of the select lever 3 is provided in the select lever device 2, and magnets 19 and 20 for detecting the lever operation position are attached to the link mechanism 31. Therefore, it is possible to amplify the magnet movement amount Lk when the select lever 3 is operated. By the way, for example, if the magnet movement amount Lk cannot be taken sufficiently and the distance between adjacent ones of the magnetic detection elements 21 to 25 is narrow, at this time, two adjacent magnetoresistive elements are simultaneously connected to the magnet 19. A situation in which the magnetic field of (20) is detected is likely to occur, and this causes erroneous detection. However, in the case of this example, as the magnet movement amount Lk is amplified, the interval between adjacent magnetic detection elements becomes sufficiently wide, so that the above-described problem is less likely to occur, and when the range position of the select lever 3 is detected. The position detection accuracy can be improved.

  Further, in order to increase the driver seat space as much as possible in order to improve the comfort of the driver's seat, the size of the select lever device 2, that is, the lever axial direction size H (see FIG. 2) of the select lever 3 is desired to be as small as possible. There is a request. In order to reduce the size H of the select lever device 2 in the lever axial direction, a measure to inevitably shorten the length of the select lever 3 is taken. By the way, if the magnets 19 and 20 are directly attached to the base end of the select lever 3 in this case, a sufficient amount of magnet movement Lk cannot be secured, leading to erroneous detection of the lever operation position. If the link mechanism 31 is used to amplify the magnet movement amount Lk, this type of concern is unlikely to occur. Therefore, the lever axial direction size H of the select lever device 2 is kept small, and a sufficient magnet movement amount Lk can be secured.

According to the configuration of the embodiment, the following effects can be obtained.
(1) Since the link mechanism 31 capable of amplifying and outputting the input operation amount of the select lever 3 is provided in the select lever device 2, the lever axial direction size H of the select lever device 2 is kept small and the lever is operated. A sufficient amount of magnet movement Lk can be ensured. Therefore, even if the select lever device 2 is downsized in the lever axial direction, the operation position detection accuracy of the range position of the select lever 3 can be ensured.

  (2) Since the lever operation position detection in the shift direction and the lever operation position detection in the select direction are detected on the same plane along the horizontal plane, the shift direction of the select lever 3 and the select are selected by one substrate 29. Both operating positions in the direction can be detected, and the number of necessary board points can be reduced.

  (3) Since the link mechanism 31 corresponds to two axes including a pair of links 34 and 35, the select lever 3 has a structure that can be operated in two axes orthogonal to the shift direction and the select direction as in this example. In addition, both the magnet movement amount Lk of the magnet 19 provided for selection direction detection and the magnet movement amount Lk of the magnet 20 provided for shift direction detection can be amplified together.

  (4) Since the link mechanism 31 has a simple structure including a pair of links 34 and 35, a slider 33, and the like, the structure of this example is used in which the magnet movement amount Lk is amplified using this type of link mechanism 31. Then, the magnet movement amount Lk can be amplified without using a complicated structure.

  (5) The magnetic lever position detection device 18 has magnets 19 and 20 attached to the select lever 3 side, and magnetic detection elements 21 to 25 attached to the case 4 side. For this reason, the magnets 19 and 20 are located on the movable side (select lever 3 side) of the select lever device 2 and the magnetic detection elements 21 to 25 are located on the fixed side (case 4 side) of the select lever device 2. It is not necessary to take a situation in which the magnetic detection elements 21 to 25 move in accordance with the lever operation when the lever 3 is operated. Therefore, sensor failure or the like due to the movement of the magnetic detection elements 21 to 25 is less likely to occur, and the effect of ensuring the operational reliability of the magnetic lever position detection device 18 is high.

  (6) Since the upper cover 27 of the detection unit 26 is provided with the pressing portion 41 for pressing the tip of the link 34 from above and the pressing portion 38 for pressing the tip of the link 35 from above, the tips of the links 34 and 35 are It is possible to prevent a situation where the surface is lifted upward due to warpage or the like.

  (7) Since the conduction hole 44 is formed by punching the upper case 4 of the detection unit 26, the magnetic fields of the magnets 19 and 20 can easily reach the magnetic detection elements 21 to 25 without being affected by other members. Highly effective in ensuring detection accuracy.

The embodiment is not limited to the configuration so far, and may be changed to the following modes.
