[0014] Below, a shift lever device 10 as a "shift device" according to this embodiment will be described with reference to the drawings. Note that in the drawings, the arrows UP, FR, and RH, which are appropriately shown, respectively indicate the upper side, front side, and right side of the shift lever device 10. In the following description, when the up / down, front / rear, and left / right directions are used, they will be described as the up / down, front / rear, and left / right directions of the shift lever device 10 unless otherwise specified.
[0015] 1 to 3, the shift lever device 10 includes a shift base 20, a lower base 24, a lever holder 30, a shift lever 34 as a "shift member," and a position detection mechanism 40. The shift lever device 10 of this embodiment is configured as a so-called by-wire type shift lever device, as an example. The shift lever 34 is configured to be operable in the front-rear direction (also referred to as the shift direction) and the left-right direction (also referred to as the select direction), and is configured to be positioned at a predetermined shift position.
[0016] Specifically, as shown in Fig. 4, the shift lever 34 is disposed in an H position (home position), and is disposed in an N position (neutral position) by being moved to the right from the H position, is disposed in an R position (reverse position) by being moved forward from the H position via the N position, and is disposed in a D position (drive position) by being moved backward from the H position via the N position. In addition, the shift lever 34 is configured to be disposed in a + position (plus position) by being moved forward from the H position, and is disposed in a - position (minus position) by being moved backward from the H position. Each component of the shift lever device 10 will be described below.
[0017] (About Shift Base 20) 1 and 2, the shift base 20 is formed in a generally rectangular cylindrical shape with the vertical direction as the axial direction. Fixing flanges 20A are formed at the lower end portions of the left and right side walls of the shift base 20, respectively, and the fixing flanges 20A protrude outward in the left-right direction from the side walls of the shift base 20. A pair of front and rear fixing holes 20B are formed to penetrate each of the fixing flanges 20A. Fastening members such as bolts are inserted into the fixing holes 20B, and the fixing flanges 20A (shift base 20) are fixed to the vehicle at the center console or the like of the vehicle.
[0018] An arrangement hole 20C for arranging a first slider 60 and a second slider 70, which will be described later, is formed through the front wall of the shift base 20. Furthermore, a base cover 22 is fixed to the upper end of the shift base 20, and an upper opening of the shift base 20 is closed by the base cover 22. A cover-side insertion hole 22A, through which a shift lever 34, which will be described later, is inserted, is formed through the base cover 22.
[0019] (About Lower Base 24) As shown in FIG. 3 , the lower base 24 is formed in a generally rectangular plate shape with its thickness extending in the up-down direction. A pair of left and right locking portions 24A are formed at the rear end of the lower base 24. The locking portions 24A extend upward from the lower base 24, with their upper ends protruding rearward. The lower base 24 is fixed to the shift base 20 so as to close the opening at the bottom of the shift base 20. Specifically, the upper ends of the locking portions 24A are disposed in locking holes (not shown) formed in the rear wall of the shift base 20 and are locked into the locking holes, and the front end of the lower base 24 is fixed by fixing pins 26 (see FIGS. 1 and 2 ) spanning the left and right side walls of the shift base 20.
[0020] A guide groove 24B is formed in the left portion of the lower base 24. The guide groove 24B is open upward and is formed in a substantially H-shape in plan view. Specifically, the guide groove 24B has a first shift groove 24B1 extending in the front-rear direction, a second shift groove 24B2 extending in the front-rear direction on the left side of the first shift groove 24B1, and a select groove 24B3 extending in the left-right direction and connecting central portions of the first shift groove 24B1 and the second shift groove 24B2 in the front-rear direction.
[0021] A detent portion 24C is formed on the right portion of the lower base 24. The detent portion 24C is formed in a substantially V-shaped groove that is open upward when viewed from the left-right direction.
[0022] (Regarding the lever holder 30) The lever holder 30 is formed in a generally rectangular block shape with the left-right direction as the longitudinal direction. A holder rotation shaft 30A is formed at each of the left and right ends of the lever holder 30, and the holder rotation shaft 30A is formed in a generally cylindrical shape with the left-right direction as the axial direction. The holder rotation shaft 30A is rotatably supported on the upper ends of the left and right side walls of the shift base 20. A lever insertion portion 30B is formed in the left portion of the lever holder 30 so as to penetrate in the vertical direction, for inserting a shift lever 34 (described later), and the lever insertion portion 30B is formed in a generally rectangular shape in a plan view.
[0023] A support pin 32, whose axial direction is the front-to-rear direction, is bridged between the front and rear side walls of the lever insertion portion 30B. The support pin 32 is formed in a substantially cylindrical shape, and the axis of the support pin 32 passes through the axis of the holder rotation shaft 30A.
[0024] A first transmission shaft 30C is formed on the right side of the lever holder 30. The first transmission shaft 30C is formed in a generally cylindrical shape with its axial direction extending in the front-to-rear direction and protrudes forward from the lever holder 30. The axis of the first transmission shaft 30C passes through the axis of the holder rotation shaft 30A. As a result, when the lever holder 30 rotates around the axis of the holder rotation shaft 30A, the tip of the first transmission shaft 30C is displaced in the up-down direction.
[0025] (About shift lever 34) The shift lever 34 is housed inside the shift base 20. The shift lever 34 has a shaft portion 34A, which is formed in a generally cylindrical shape extending in the vertical direction. The shaft portion 34A is inserted into the lever insertion portion 30B of the lever holder 30, and a vertically intermediate portion of the shaft portion 34A is rotatably supported by a support pin 32. The upper end portion of the shaft portion 34A is inserted into the cover-side insertion hole 22A of the base cover 22 and protrudes upward from the base cover 22 so as to be operable (see FIG. 2). Furthermore, a shift knob (not shown) that is gripped by the operator is provided at the upper end portion of the shaft portion 34A. As a result, when an operator holding the shift knob operates the shift lever 34 in the shift direction, the shaft portion 34A (shift lever 34) rotates around the axis of the holder rotation axis 30A together with the lever holder 30, and when the operator operates the shift lever 34 in the select direction, the shaft portion 34A (shift lever 34) rotates around the axis of the support pin 32, and the shift lever 34 is set to be positioned at each shift position.
[0026] The lower end of the shaft portion 34A is inserted into the guide groove 24B of the lower base 24. Specifically, when the shift lever 34 is in the H position, the shaft portion 34A is located at the right end of the select groove 24B3. When the shift lever 34 is operated to each shift position, the shaft portion 34A moves in the shift direction or the select direction along the guide groove 24B.
[0027] A pin holding portion 34B is provided at the lower end of the shift lever 34, protruding diagonally downward and substantially to the right from the shaft portion 34A. The pin holding portion 34B is formed in a substantially cylindrical shape with a bottom that opens downward. A substantially round rod-shaped detent pin 36 and a biasing spring (not shown) are inserted into the pin holding portion 34B, and the detent pin 36 is biased toward its tip by the biasing spring. The tip of the detent pin 36 is formed in a substantially hemispherical shape and abuts against a detent portion 24C of the lower base 24. The shift lever 34 is held in the H position by the detent portion 24C and the detent pin 36, and the shape of the detent portion 24C is set so that the shift lever 34 returns to the H position when the shift lever 34 is operated to each shift position.
[0028] A second transmission shaft 34C is formed at the lower end of the shift lever 34, below the support pin 32. The second transmission shaft 34C is formed in a generally cylindrical shape with its axial direction extending in the front-to-rear direction and protruding forward from the shaft portion 34A. As a result, when the shift lever 34 rotates around the axis of the support pin 32, the tip of the second transmission shaft 34C is displaced in the left-right direction.
[0029] (Regarding the position detection mechanism 40) 1, 2, 5, and 6, the position detection mechanism 40 is disposed adjacent to the front side of the shift base 20, and is configured as a mechanism for detecting the shift position (operating position) of the shift lever 34. The position detection mechanism 40 is configured to include a case 50 as a "support member," a first slider 60 and a second slider 70 as "moving members," a link 80 as a "moving member," a first magnet 100 and a second magnet 102 as "magnets," a substrate 110, and a case cover 120.
[0030] (About Case 50) The case 50 is formed in a generally rectangular box shape that is open to the front side, and is fastened to the front wall of the shift base 20 by a plurality of screws SC1.
[0031] 7(A) and 7(B), a slider accommodating portion 51 for accommodating a first slider 60 (described later) is formed at the upper end of the case 50 at a position corresponding to the first transmission shaft 30C of the lever holder 30. The slider accommodating portion 51 is formed in a generally rectangular tubular shape with the vertical direction as the longitudinal direction and the horizontal direction as the width direction, and protrudes rearward from the bottom wall of the case 50. The interior of the slider accommodating portion 51 is penetrated in the front-rear direction, and the slider accommodating portion 51 is open upward. The left and right side walls of the slider accommodating portion 51 are configured as first restricting portions 51A, which serve as "restricting portions," and the first restricting portions 51A extend in the vertical direction.
[0032] As shown in FIGS. 2 and 7, a pair of left and right first slider support portions 52 are formed on the bottom wall at the upper end of the case 50, behind the slider accommodating portion 51. The pair of first slider support portions 52 protrude rearward from the bottom wall of the case 50, behind the first restricting portion 51A, and extend in the up-down direction. The pair of first slider support portions 52 are disposed in the arrangement hole 20C of the shift base 20. Each of the pair of first slider support portions 52 has a first slide groove 52A formed on a side surface facing each other in the left-right direction. The first slide groove 52A opens inward in the width direction (left-right direction) of the slider accommodating portion 51 and extends in the up-down direction, with the upper end of the first slide groove 52A opening upward.
[0033] 2 and 8, a pair of upper and lower second slider support portions 53 for assembling a second slider 70 (described later) is formed on the bottom wall of the case 50 at a position corresponding to the second transmission shaft 34C of the shift lever 34. The second slider support portions 53 are formed in a substantially rectangular plate shape with the plate thickness direction in the up-down direction, protrude rearward from the case 50, and are disposed in the arrangement hole 20C of the shift base 20. A second slide groove 53A extending in the left-right direction is formed on each of the pair of second slider support portions 53 on surfaces facing each other in the up-down direction. The second slide groove 53A is open in the direction in which the second slider support portions 53 face each other and to the left.
[0034] A link support shaft 54 for supporting a link 80, which will be described later, is formed on the bottom wall of the case 50 between the pair of second slider support portions 53. The link support shaft 54 is formed in a substantially cylindrical shape with its axial direction extending in the front-to-rear direction, and protrudes forward from the bottom wall of the case 50. As shown in FIGS. 5 and 6 , a link insertion hole 55 is formed through the bottom wall of the case 50 below the link support shaft 54. The link insertion hole 55 is formed in the shape of an elongated hole that extends circumferentially around the link support shaft 54.
[0035] A lower case rib 56 is formed on the bottom wall of the case 50 below the link support shaft 54. When viewed from the front, the lower case rib 56 extends in a generally arcuate shape centered on the axis of the link support shaft 54 and protrudes forward from the bottom wall of the case 50. A second restricting portion 57 serving as a "restricting portion" is formed at the tip of the lower case rib 56 below the link support shaft 54. The second restricting portion 57 extends from the tip of the lower case rib 56 radially inward (upward) of the lower case rib 56 and is bent forward (see FIG. 8 ). Similarly to the lower case rib 56, the second restricting portion 57 also extends in a generally arcuate shape centered on the axis of the link support shaft 54 when viewed from the front. This allows the second restricting portion 57 to be spaced forward from the bottom wall of the case 50.
[0036] An upper case rib 58 is formed on the bottom wall of the case 50 above the link support shaft 54. When viewed from the front, the upper case rib 58 extends in a generally arcuate shape centered on the axis of the link support shaft 54 and protrudes forward from the bottom wall of the case 50. A restricting piece 59 is formed on the tip of the upper case rib 58 above the link support shaft 54. The restricting piece 59 extends from the tip of the upper case rib 58 radially inward (downward) of the upper case rib 58 and, like the upper case rib 58, extends in a generally arcuate shape centered on the axis of the link support shaft 54 when viewed from the front. This allows the restricting piece 59 to be positioned at a distance forward from the bottom wall of the case 50.
[0037] (Regarding the first slider 60) As shown in Figures 5 to 7 and 9, the first slider 60 is made of resin and is formed in the shape of a generally rectangular block with its longitudinal direction extending up and down and its width direction extending left and right. A pair of left and right first slide rails 61 is formed on the left and right side surfaces of the rear portion of the first slider 60, and the first slide rails 61 extend in the up and down direction. The first slider 60 is accommodated from above in the slider accommodating portion 51 of the case 50, and the pair of left and right first slide rails 61 are inserted into the first slide grooves 52A of the case 50 so as to be slidable in the up and down direction. This allows the first slider 60 to be connected to the case 50 so as to be slidable in the up and down direction.
[0038] A connecting recess 62 (see FIG. 7(B)) is formed in the upper part of the first slider 60, and the connecting recess 62 is formed in a concave shape that is open to the rear. The tip end of the first transmission shaft 30C of the lever holder 30 is inserted into the connecting recess 62 from the rear side and engages with the inner peripheral surface of the connecting recess 62 in the vertical direction. As a result, when the shift lever 34 is operated in the shift direction, the lever holder 30 rotates around the holder rotation shaft 30A, and the first transmission shaft 30C causes the first slider 60 to slide in the vertical direction in conjunction with the operation of the shift lever 34.
[0039] A slider biasing spring 90 (see FIG. 7(B)), which is configured as a compression coil spring, is housed within the connecting recess 62. The slider biasing spring 90 is disposed between the bottom surface of the connecting recess 62 and the tip end of the first transmission shaft 30C, and biases the first slider 60 forward. This causes the first slide rail 61 to abut against the front surface of the first slide groove 52A of the case 50, determining the position of the first slider 60 in the front-to-rear direction relative to the case 50.
[0040] A first magnet storage section 63 serving as a storage section is formed in the lower part of the first slider 60. The first magnet storage section 63 is formed in a recessed shape that is open to the front, and is formed in a substantially rectangular shape with the vertical direction as the longitudinal direction when viewed from the front. Furthermore, a through-hole 64 that penetrates in the front-rear direction is formed in the vertical intermediate part of the bottom wall of the first magnet storage section 63.
[0041] Furthermore, a pair of upper and lower slits 65 are formed on the left and right side walls of the first magnet accommodating portion 63, on the outer side in the width direction relative to the through-hole 64. The slits 65 are open to the front and penetrate in the left-right direction, with the bottom of the slits 65 located rearward of the bottom surface of the first magnet accommodating portion 63. As a result, an engagement claw 66 is formed on each of the left and right side walls of the first magnet accommodating portion 63, between the pair of slits 65, and the engagement claws 66 are configured to be elastically deformable in the left-right direction. In other words, the engagement claws 66 are configured to be elastically deformable in a direction perpendicular to the moving direction of the first slider 60, as viewed from the front.
[0042] The engagement claw 66 is disposed adjacent to the first restricting portion 51A of the case 50 on the inner side in the width direction of the slider accommodating portion 51. That is, the engagement claw 66 and the first restricting portion 51A are disposed facing each other in a direction perpendicular to the moving direction of the first slider 60. As a result, when the first slider 60 is accommodated in the slider accommodating portion 51, the first restricting portion 51A restricts deformation of the engagement claw 66 outward in the left-right direction (toward the exterior of the slider accommodating portion 51). In addition, a hook portion 66A protruding inward in the width direction of the first slider 60 is formed at the tip of the engagement claw 66.
[0043] Furthermore, a pair of upper and lower sliding protrusions 67 are formed on the left and right side surfaces of the first slider 60, respectively, on the front side of the first slide rail 61. The sliding protrusions 67 protrude outward in the width direction from the first slider 60 and are formed in a substantially semicircular shape when viewed from the front. The sliding protrusions 67 abut against the first restricting portion 51A of the case 50. As a result, the sliding protrusions 67 and the first restricting portion 51A determine the left-right position of the first slider 60 relative to the case 50. When the first slider 60 slides up and down, the sliding protrusions 67 slide on the inner circumferential surface of the first restricting portion 51A. In other words, the first restricting portion 51A is configured as a portion that guides the sliding of the first slider 60.
[0044] (Regarding the second slider 70) 2 and 8, the second slider 70 is formed in a generally rectangular block shape and is disposed between a pair of upper and lower second slider support portions 53 of the case 50. Second slide rails 71 are formed on the upper and lower surfaces of the second slider 70, respectively, and extend in the left-right direction. The second slide rails 71 are inserted into the second slide grooves 53A of the case 50 so as to be slidable in the left-right direction. This allows the second slider 70 to be connected to the case 50 so as to be slidable in the left-right direction.
[0045] A connecting groove 72 that is open to the rear is formed in the center in the left-right direction on the rear portion of the second slider 70, and extends in the up-down direction. The second transmission shaft 34C of the shift lever 34 is inserted into the connecting groove 72 and engages with the inner peripheral surface of the connecting groove 72 in the left-right direction. As a result, when the shift lever 34 is operated in the select direction and the shift lever 34 rotates around the axis of the support pin 32, the second transmission shaft 34C causes the second slider 70 to slide left-right in conjunction with the operation of the shift lever 34.
[0046] A connecting tubular portion 73 is formed in the center in the left-right direction at the front portion of the second slider 70. The connecting tubular portion 73 is formed in a substantially rectangular tubular shape with the axial direction being the front-rear direction and the longitudinal direction being the up-down direction.
[0047] (About Link 80) 5, 6, 8, and 10, the link 80 is made of resin and is formed in the shape of a generally long rectangular block. A link pivot shaft 81 is formed in the middle of the link 80 in the longitudinal direction. The link pivot shaft 81 is formed in the shape of a generally closed-end cylinder that is open to the rear, and the front end of the link pivot shaft 81 protrudes forward from the link 80. The link support shaft 54 of the case 50 is fitted into the link pivot shaft 81, and the link pivot shaft 81 is rotatably supported by the link support shaft 54.
[0048] Furthermore, a pair of stopper portions 82A, 82B that protrude outward in the longitudinal direction of the link 80 are formed at both longitudinal ends of the link 80. The stopper portion 82A at one longitudinal end of the link 80 is disposed adjacent to the rear side of the second restricting portion 57 of the case 50, and the stopper portion 82B at the other longitudinal end of the link 80 is disposed adjacent to the rear side of the restricting piece 59 of the case 50 (see FIGS. 6 and 8). This restricts the forward movement of the link 80.
[0049] Furthermore, a link biasing spring 92 (see FIG. 8), which is configured as a compression coil spring, is housed inside the link support shaft 54 of the case 50. A spherical ball 94 (see FIG. 8) is also housed inside the link support shaft 54, and the ball 94 is disposed between the top wall of the link pivot shaft 81 of the link 80 and the link biasing spring 92. The ball 94 is pressed against the top wall of the link pivot shaft 81 by the biasing force of the link biasing spring 92. As a result, the link 80 is biased forward by the link biasing spring 92, and the stopper portions 82A and 82B of the link 80 abut against the second restricting portion 57 and the restricting piece 59 of the case 50. In other words, the position of the link 80 in the front-to-rear direction relative to the case 50 is determined.
[0050] An operating shaft 83 is formed in the longitudinal middle of the link 80. The operating shaft 83 is formed in a generally cylindrical shape with its axial direction aligned in the front-to-rear direction and protrudes rearward from the link 80. The operating shaft 83 is located closer to one end of the link 80 than the link pivot shaft 81. The operating shaft 83 passes through the link insertion hole 55 of the case 50 and is inserted into the connecting tubular portion 73 of the second slider 70, engaging with the inner circumferential surface of the connecting tubular portion 73 in the left-to-right direction. Therefore, when the second slider 70 slides left-to-right, the link 80 pivots about the link pivot shaft 81. Specifically, when the shift lever 34 is in the H position, the link 80 is located in an initial position (the position shown in FIG. 6 ). When the shift lever 34 is moved from the H position to the N position, the link 80 pivots counterclockwise from the initial position as viewed from the front.
[0051] A second magnet accommodating portion 84 serving as an "accommodating portion" is formed at one longitudinal end of the link 80. The second magnet accommodating portion 84 is formed in a recessed shape that opens to the front and is generally trapezoidal when viewed from the front. Furthermore, a pair of slits 85 are formed in the side wall of the second magnet accommodating portion 84 on one longitudinal side of the link 80, and the slits 85 are spaced apart in the width direction of the link 80. The slits 85 are open to the front and penetrate the link 80 in the longitudinal direction. As a result, an engagement claw 86 is formed in the side wall of the second magnet accommodating portion 84 between the pair of slits 85. The engagement claw 86 is located in the center of the width direction of the link 80 and is configured to be elastically deformable in the longitudinal direction of the link 80. In other words, when viewed from the front, the engagement claw 86 is configured to be elastically deformable in a direction perpendicular to the movement direction (rotation direction) of the link 80.
[0052] Furthermore, the engagement claw 86 is disposed adjacent to the second restricting portion 57 of the case 50 on the radially inner side of the second restricting portion 57. That is, when viewed from the front side, the engagement claw 86 and the second restricting portion 57 are disposed opposite each other in a direction (longitudinal direction of the link 80) perpendicular to the movement direction (rotation direction) of the link 80. As a result, when the link 80 is connected to the case 50, the second restricting portion 57 restricts deformation of the engagement claw 86 toward one longitudinal side of the link 80 (outside the second magnet accommodating portion 84). Furthermore, a hook portion 86A is formed at the tip of the engagement claw 86, and the hook portion 86A protrudes toward the other longitudinal side of the link 80 (inside the second magnet accommodating portion 84).
[0053] Furthermore, a magnet stopper 87 is formed on the link 80 in front of the opening on the other end side of the link 80 in the second magnet accommodating portion 84. The magnet stopper 87 extends in the width direction of the link 80, and both longitudinal ends of the magnet stopper 87 are connected to the side walls in the width direction of the second magnet accommodating portion 84. In this way, the magnet stopper 87 is formed to block a part of the opening of the second magnet accommodating portion 84.
[0054] Furthermore, the opening edge of the second magnet housing portion 84 on the other end side of the link 80 is formed with a housing portion side chamfer 84A (see FIG. 8).
[0055] (Regarding the first magnet 100) As shown in FIGS. 2 and 5 to 7, the first magnet 100 is formed in a generally rectangular parallelepiped shape with its longitudinal direction extending vertically, corresponding to the first magnet housing portion 63 of the first slider 60. The first magnet 100 is housed (fitted) within the first magnet housing portion 63 of the first slider 60 and held by the first slider 60. This allows the first magnet 100 to move (slide) vertically together with the first slider 60. When the first magnet 100 is housed in the first magnet housing portion 63, the hook portions 66A of the engagement claws 66 engage with the left and right front corners of the first magnet 100, preventing the first magnet 100 from falling out of the first magnet housing portion 63 (see FIGS. 7A and 7B). In other words, the first magnet 100 is held by the first slider 60 by a so-called snap fit.
[0056] (Regarding the second magnet 102) As shown in FIGS. 2, 5, 6, and 8, the second magnet 102 is formed in a generally trapezoidal block shape corresponding to the second magnet housing portion 84 of the link 80 when viewed from the front. Specifically, the widthwise length of one end (lower end) of the second magnet 102 is set to be longer than the widthwise length of the other end (upper end) of the second magnet 102. Furthermore, magnet side chamfers 102A (see FIG. 8) are formed at the rear corners of the one and other ends of the second magnet 102. The second magnet 102 is housed (fitted) in the second magnet housing portion 84 of the link 80 and is held by the link 80. This allows the second magnet 102 to rotate integrally with the link 80.
[0057] When the second magnet 102 is housed in the second magnet housing portion 84, the hook portion 86A of the engagement claw 86 engages with a front corner at one end of the second magnet 102, and the magnet stopper portion 87 is disposed adjacent to the front side of the other end of the second magnet 102 (see FIG. 8). This results in a configuration in which the hook portion 86A and the magnet stopper portion 87 prevent the second magnet 102 from falling out of the second magnet housing portion 84.
[0058] Additionally, the second magnet housing portion 84 of the link 80 is disposed closer to one end of the link 80 than the operating shaft 83 of the link 80. That is, the second magnet 102 is disposed closer to one end of the link 80 than the operating shaft 83. For this reason, when the link 80 rotates, the amount of rotation of the second magnet 102 is set to be larger than the amount of rotation of the operating shaft 83. In other words, the link 80 is configured as a member that amplifies the amount of movement of the second magnet 102 relative to the amount of movement of the shift lever 34.
[0059] (Regarding the substrate 110) 2, the substrate 110 is formed in a substantially rectangular plate shape with its thickness direction extending in the front-to-rear direction. The substrate 110 is housed in the case 50 on the front side of the link 80 and the first slider 60, and is fastened to the case 50 with screws SC2. A connector 112 is provided on the left side of the front surface of the substrate 110. A connector of the vehicle is connected to the connector 112, and the substrate 110 is electrically connected to a control unit (not shown) of the vehicle.
[0060] As shown in FIGS. 7A and 7B, a first Hall IC 114 serving as a "sensor" is provided on the rear surface (one side surface) of the substrate 110, in front of the first magnet 100. Also, as shown in FIGS. 6 and 8, four second Hall ICs 116 serving as "sensors" are provided on the rear surface of the substrate 110. Two of the second Hall ICs 116 are disposed in front of the second magnet 102, and when the shift lever 34 is operated to the N position, the other two second Hall ICs 116 are disposed in front of the second magnet 102. The first Hall IC 114 (second Hall IC 116) detects the magnetic flux density of the first magnet 100 (second magnet 102) and outputs an output value (voltage value) corresponding to the detected magnetic flux density to the control unit. The control unit then detects the shift position of the shift lever 34 based on the output values from the first Hall IC 114 and the second Hall IC 116.
[0061] 2, a shield plate 118 is provided on the front side of the substrate 110. The shield plate 118 is made of a metal plate, is disposed with its thickness in the front-to-rear direction, and is formed into a predetermined shape. The shield plate 118 is fixed to the case 50 together with the substrate 110 by screws SC2.
[0062] (About the case cover 120) The case cover 120 is formed in a generally rectangular box shape that is open to the rear side, and is fixed to the case 50 by claw engagement so as to cover the opening of the case 50.
[0063] (Operation of shift lever 34) In the shift lever device 10 configured as described above, when the shift lever 34 is operated in the shift direction (forward / backward), the shift lever 34 rotates together with the lever holder 30 around the holder rotation shaft 30A of the lever holder 30. This causes the tip of the first transmission shaft 30C of the lever holder 30 to displace in the up / down direction.
[0064] When the first transmission shaft 30C is displaced in the up-down direction, the first slider 60 connected to the first transmission shaft 30C slides in the up-down direction. This causes the first magnet 100 to be displaced in the up-down direction together with the first slider 60. As a result, the first Hall IC 114 detects the magnetic flux density of the first magnet 100 and outputs an output value corresponding to the detected magnetic flux density to the control unit.
[0065] Furthermore, when the shift lever 34 is operated in the select direction (left / right direction), the shift lever 34 rotates around the axis of the support pin 32. As a result, the tip of the second transmission shaft 34C of the shift lever 34 is displaced left / right.
[0066] When the second transmission shaft 34C is displaced left and right, the second slider 70 connected to the second transmission shaft 34C slides left and right. This causes the link 80 connected to the second slider 70 to rotate about the axis of the link rotation shaft 81. Therefore, the second magnet 102 rotates together with the link 80 about the axis of the link rotation shaft 81. As a result, the second Hall IC 116 detects the magnetic flux density of the second magnet 102 and outputs an output value corresponding to the detected magnetic flux density to the control unit. The control unit then detects the shift position of the shift lever 34 based on the output values from the first Hall IC 114 and the second Hall IC 116.
[0067] (Action and effect) Next, the operation and effect of this embodiment will be described while explaining the assembly procedure for assembling the first magnet 100 to the first slider 60 and the assembly procedure for assembling the second magnet 102 to the link 80.
[0068] When assembling the first magnet 100 to the first slider 60, the first magnet 100 is placed in front of the first magnet accommodating portion 63 of the first slider 60. Then, the first magnet 100 is moved rearward to be accommodated (fitted) in the first magnet accommodating portion 63. At this time, the hook portions 66A of the engagement claws 66 of the first slider 60 are pressed by the left and right corners of the first magnet 100, causing the engagement claws 66 to elastically deform outward in the left-right direction (toward the exterior of the first magnet accommodating portion 63). Then, when the first magnet 100 is accommodated (fitted) in the first magnet accommodating portion 63, the engagement claws 66 elastically deform inward in the left-right direction (toward the interior of the first magnet accommodating portion 63), causing the hook portions 66A to engage with the front corners of the first magnet 100. As described above, the first magnet 100 can be easily assembled to the first slider 60.
[0069] Then, the first slider 60 with the first magnet 100 assembled thereto is slidably coupled to the case 50. Specifically, the first slider 60 is inserted from above into the slider accommodating portion 51 of the case 50, and the first slide rail 61 of the first slider 60 is inserted into the first slide groove 52A of the case 50. As a result, the first restricting portion 51A of the slider accommodating portion 51 is disposed adjacent to the engaging claw 66 of the first slider 60 on the outer side in the width direction of the first slider 60. Therefore, for example, if the engaging claw 66 is deformed outward in the width direction of the first slider 60 due to a change in ambient temperature or the like, the engaging claw 66 will come into contact with the first restricting portion 51A. That is, the first restricting portion 51A can restrict deformation of the engaging claw 66 in a direction that disengages it from the first magnet 100. This allows the engagement state between the engaging claw 66 and the first magnet 100 to be maintained in a good condition. As described above, according to the shift lever device 10 of this embodiment, the ease of assembling the first magnet 100 to the first slider 60 can be improved, and the assembled state of the first magnet 100 to the first slider 60 can be maintained in good condition.
[0070] On the other hand, when assembling the second magnet 102 to the link 80, the second magnet 102 is placed in front of the second magnet accommodating portion 84 of the link 80. At this time, as shown in FIG. 11 , the other end of the second magnet 102 is tilted toward the second magnet accommodating portion 84 when viewed from the width direction of the link 80. Then, the other end of the second magnet 102 is inserted into the second magnet accommodating portion 84 so as to slip behind the magnet stop portion 87 of the link 80. After the other end of the second magnet 102 is inserted into the second magnet accommodating portion 84, one end of the second magnet 102 is pushed toward the second magnet accommodating portion 84 so as to rotate the second magnet 102. As a result, the magnet side chamfer 102A on one end side of the second magnet 102 presses against the hook portion 86A of the engagement claw 86, causing the engagement claw 86 to elastically deform toward one longitudinal side of the link 80 (toward the outside of the second magnet accommodating portion 84) (see the engagement claw 86 indicated by the two-dot chain line in FIG. 11). Then, when the second magnet 102 is accommodated in the second magnet accommodating portion 84, the engagement claw 86 elastically deforms toward the other longitudinal side of the link 80 (toward the inside of the second magnet accommodating portion 84), causing the hook portion 86A to engage with a corner at one end of the second magnet 102 (see FIG. 8). In this way, the second magnet 102 is assembled to the link 80.
[0071] Then, the link 80 with the second magnet 102 assembled thereto is rotatably connected to the case 50. Specifically, the link 80 is positioned on the front side of the case 50 so that the stopper portions 82A and 82B of the link 80 do not overlap with the second restricting portion 57 and restricting piece 59 of the case 50 when viewed from the front, and the link support shaft 54 of the case 50 is inserted into the link pivot shaft 81 of the link 80. After the link support shaft 54 is inserted into the link pivot shaft 81, the link 80 is rotated counterclockwise to be positioned in its initial position. As a result, the stopper portion 82A is positioned behind the second restricting portion 57, and the stopper portion 82B is positioned behind the restricting piece 59. In this state, the second restricting portion 57 is positioned adjacent to one longitudinal side of the link 80 with respect to the engaging claw 86 of the link 80. Therefore, for example, if the engagement pawl 86 is deformed to one side in the longitudinal direction of the link 80 due to a change in environmental temperature or the like, the engagement pawl 86 will come into contact with the second restricting portion 57. In other words, the second restricting portion 57 can restrict the deformation of the engagement pawl 86 in the direction that disengages it from the second magnet 102. This makes it possible to maintain a good engagement state between the engagement pawl 86 and the second magnet 102. As described above, according to the shift lever device 10 of this embodiment, it is possible to improve the ease of assembling the second magnet 102 to the link 80, and also to maintain a good assembly state of the second magnet 102 to the link 80.
[0072] Furthermore, the engagement claw 66 of the first slider 60 is configured to be elastically deformable in the left-right direction (a direction perpendicular to the movement direction of the first slider 60) when viewed from the front. Furthermore, the first restricting portion 51A of the case 50 and the engagement claw 66 are arranged opposite to each other in the left-right direction, and the first restricting portion 51A extends in the up-down direction (the movement direction of the first slider 60). Therefore, the opposing state between the engagement claw 66 and the first restricting portion 51A can be maintained throughout the entire movement range of the first slider 60, and displacement of the engagement claw 66 outward in the width direction of the first slider 60 can be restricted. Therefore, the engagement state between the engagement claw 66 and the first magnet 100 can be maintained even better.
[0073] Furthermore, the engagement claw 86 of the link 80 is configured to be elastically deformable in the longitudinal direction of the link 80 (a direction perpendicular to the rotation direction of the link 80) when viewed from the front. Furthermore, the second restricting portion 57 of the case 50 and the engagement claw 86 are disposed opposite to each other in the longitudinal direction of the link 80, and the second restricting portion 57 extends in an arc shape centered on the axis of the link support shaft 54. In other words, the second restricting portion 57 extends along the rotation direction of the link 80. Therefore, the opposing state between the engagement claw 86 and the second restricting portion 57 can be maintained throughout the entire rotation range of the link 80, and displacement of the engagement claw 86 to one side in the longitudinal direction of the link 80 can be restricted. Therefore, the engagement state between the engagement claw 86 and the second magnet 102 can be maintained even better.
[0074] The first slider 60 is also provided with a pair of engaging claws 66, which are respectively arranged on the outer left and right sides of the first magnet 100. This allows both widthwise sides of the first magnet 100 to engage with the pair of engaging claws 66. This allows the first slider 60 to stably hold the first magnet 100.
[0075] Furthermore, a pair of upper and lower sliding protrusions 67 are formed on each of the left and right side surfaces of the first slider 60, and the sliding protrusions 67 abut against the first restricting portion 51A of the case 50. When the first slider 60 slides up and down, the sliding protrusions 67 slide on the inner circumferential surface of the first restricting portion 51A. This makes it possible to guide the sliding of the first slider 60 by utilizing the first restricting portion 51A, which restricts deformation of the engagement claw 66 in the direction away from the first magnet 100.
[0076] The link 80 is formed in an elongated shape, and a link rotation shaft 81 rotatably supported by the case 50 is formed in the longitudinal middle portion of the link 80. A second magnet accommodating portion 84 is formed in one longitudinal end portion of the link 80, and an engaging claw 86 is disposed on one longitudinal side of the link 80 relative to the second magnet accommodating portion 84. The link 80 is further formed with a magnet stopper portion 87 that closes a portion of the opening of the second magnet accommodating portion 84. Therefore, even when a second magnet 102 is attached to the rotatable link 80, the engaging claw 86 and the magnet stopper portion 87 can prevent the second magnet 102 from falling out of the second magnet accommodating portion 84. This stabilizes the holding state of the second magnet 102 in the link 80.
[0077] Additionally, magnet side chamfers 102A are formed at rear corners of one end and the other end of the second magnet 102. This prevents the second magnet 102 from interfering with the bottom surface of the second magnet housing portion 84 when the second magnet 102 is housed in the second magnet housing portion 84. This further improves the ease of assembly of the second magnet 102.
[0078] Furthermore, a housing chamfered portion 84A is formed on the edge of the opening on the other end side of the link 80 in the second magnet housing portion 84. This effectively improves the ease of assembling the second magnet 102 to the second magnet housing portion 84. That is, as shown in FIG. 11 , when assembling the second magnet 102 to the link 80, if the other end of the second magnet 102 is placed under the magnet stopper portion 87, the front corner of the other end of the second magnet 102 comes close to the edge of the opening in the second magnet housing portion 84. For this reason, if the housing chamfered portion 84A were omitted from the second magnet housing portion 84, the front corner of the other end of the second magnet 102 would interfere with the edge of the opening in the second magnet housing portion 84, which could reduce the ease of assembling the second magnet 102 to the second magnet housing portion 84. In contrast, in the present embodiment, the edge of the opening of the second magnet storage portion 84 is formed with a storage portion side chamfer 84A, which prevents interference between the front corner of the other end of the second magnet 102 and the edge of the opening of the second magnet storage portion 84. Furthermore, at this time, the engagement claw 86 of the link 80 is elastically deformed, so that a pressing force F acts from the engagement claw 86 on the second magnet 102 toward the other end of the link 80. This allows the front corner of the other end of the second magnet 102 to be guided by the storage portion side chamfer 84A, lifting the other end of the second magnet 102 forward while storing the second magnet 102 in the second magnet storage portion 84. This effectively improves the ease of assembling the second magnet 102 into the second magnet storage portion 84. [Explanation of symbols]
