Abstract

The invention aims to improve the assembling performance of a pin to a base component. For this reason, in the shift lever device, the pin main body of the pin is inserted through the first and second support holes of the shift base and the first and second fixed holes of the lower base. Further, the flange constituting the right end portion of the pin body abuts against the bottom surface of the flange housing portion of the shift base, and the movement of the pin to the left side is restricted. The fixing pawl extending leftward from the flange is elastically deformable in the front-rear direction, and the hook portion of the fixing pawl engages with the engaging hole of the shift base, thereby restricting the movement of the pin to the right. Thus, the pin can be assembled to the shift base without using another member such as a push nut. Therefore, the assembling property of the pin to the shift base can be improved.

The shift lever 34 is configured to be operable in a front-rear direction (also referred to as a shift direction) and a left-right direction (also referred to as a select direction), and is arranged at a predetermined shift position.

Specifically, as shown in fig. 5, the shift lever 34 is disposed at the H position (home position), disposed at the N position (neutral position) by being operated from the H position to the right side, disposed at the R position (reverse position) by being operated from the H position to the front side via the N position, and disposed at the D position (drive position) by being operated from the H position to the rear side via the N position. The shift lever 34 is arranged at the + position (upshift position) by being operated from the H position to the front side, and arranged at the-position (downshift position) by being operated from the H position to the rear side. Hereinafter, each configuration of the shift lever device 10 will be described.

(with respect to the shift base 20)

As shown in fig. 1 and 2, the shift base 20 is formed in a substantially rectangular tubular shape with the vertical direction as the axial direction. Fixing flanges 20A are formed at lower end portions of the left and right side walls of the shift base 20, respectively, and the fixing flanges 20A project outward in the left-right direction from the shift base 20 from the side walls of the shift base 20. A pair of front and rear fixing holes 20B are formed through the fixing flange 20A. Fastening members such as bolts are inserted into the fixing holes 20B to fix the fixing flange 20A (shift base 20) to the vehicle at a center console of the vehicle or the like.

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. As shown in fig. 3, a pair of right and left locking holes 20D for locking a lower base 24 described later are formed through the rear wall of the shift base 20, and the locking holes 20D are formed in a substantially rectangular shape with the right and left direction as the longitudinal direction.

A flange receiving portion 20E for receiving a flange 28 of a pin 26 described later is formed at a lower distal end portion of an outer peripheral surface of a right wall of the shift base 20. The flange receiving portion 20E is formed in a concave shape that opens to the right side, and is formed in a substantially elliptical shape whose longitudinal direction is the front-rear direction when viewed from the right side. A first support hole 20F, which is a circular support hole, is formed in the bottom surface of the flange housing portion 20E so as to penetrate in the left-right direction. Further, a second support hole 20G as a "support hole" in a circular shape is formed through the left wall of the shift base 20 in the left-right direction, and the second support hole 20G is disposed coaxially with the first support hole 20F. The diameter of the second support hole 20G is set smaller than the diameter of the first support hole 20F.

Further, a pawl housing groove portion 20H, which is a "groove portion", for housing a fixing pawl 29 of a pin 26 described later is formed at a lower right end portion on an outer peripheral surface of the front wall of the shift base 20. The pawl housing groove portion 20H is formed in a concave shape open to the front and right sides, and extends in the left-right direction. The vertically intermediate portion of the front end of the flange receiving portion 20E extends forward and communicates with the right end of the pawl receiving groove portion 20H. Further, a substantially rectangular engagement hole 20J is formed in the bottom surface of the pawl housing groove portion 20H so as to penetrate in the front-rear direction at the right end portion.

As shown in fig. 2, a base cover 22 is fixed to an upper end portion of the shift base 20, and an upper opening portion of the shift base 20 is closed by the base cover 22. A cover-side insertion hole 22A through which a shift lever 34 described later is inserted is formed in the base cover 22.

(about lower base 24)

As shown in fig. 4, the lower base 24 is formed in a substantially rectangular plate shape whose vertical direction is the thickness direction. The lower base 24 is fixed to the shift base 20 so as to close the opening on the lower side of the shift base 20. The fixing structure of the lower base 24 will be described later.

A guide groove 24B is formed in the left portion of the lower base 24. The guide groove 24B is open to the upper side and is formed in a substantially H shape in plan view. Specifically, the guide groove 24B includes: 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 24B 1; and a shift select groove 24B3 extending in the left-right direction and connecting front-rear direction intermediate portions of the first shift groove 24B1 and the second shift groove 24B 2.

Further, a stopper 24C is formed on the right portion of the lower base 24. The stopper portion 24C is formed in a substantially V-shaped groove shape that opens upward when viewed from the left-right direction.

(rod holder 30)

The rod holder 30 is formed in a substantially rectangular block shape having a longitudinal direction in the left-right direction. The holder rotating shafts 30A are formed at both ends of the rod holder 30 in the left-right direction, respectively, and the holder rotating shafts 30A are formed in a substantially cylindrical shape with the left-right direction as an axial direction. The holder rotating shaft 30A is rotatably supported by upper end portions of the left and right side walls of the shift base 20. A lever insertion portion 30B for inserting a shift lever 34, which will be described later, is formed to penetrate in the vertical direction in the left portion of the lever holder 30, and the lever insertion portion 30B is formed to be substantially rectangular in plan view.

Support pins 32 are provided on the front and rear side walls of the rod insertion portion 30B in the front-rear direction as an axial direction. 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 rotating shaft 30A.

A first transmission shaft 30C is formed at the right portion of the lever holder 30. The first transmission shaft 30C is formed in a substantially cylindrical shape with the front-rear direction as the axial direction, and protrudes forward from the rod holder 30. The axis of the first transmission shaft 30C passes through the axis of the holder rotating shaft 30A. Thus, when the lever holder 30 rotates about the holder rotation shaft 30A, the tip end portion of the first transmission shaft 30C is displaced in the vertical direction.

(about the shift lever 34)

The shift lever 34 is housed inside the shift base 20. The shift lever 34 has a shaft portion 34A, and the shaft portion 34A is formed in a substantially cylindrical shape extending in the vertical direction. The shaft portion 34A is inserted into the rod insertion portion 30B of the rod holder 30, and a vertically intermediate portion of the shaft portion 34A is rotatably supported by the support pin 32. The upper end of the shaft 34A is inserted into the cover-side insertion hole 22A of the base cover 22 and operatively protrudes upward from the base cover 22 (see fig. 2). A shift lever (not shown) to be gripped by an operator is provided at an upper end of the shaft portion 34A. This makes the following settings: when the operator who grips the shift knob operates the shift lever 34 in the shifting direction, the shaft portion 34A (shift lever 34) rotates together with the lever holder 30 about the axis of the holder rotation shaft 30A, and when the shift lever 34 is operated in the selecting direction, the shaft portion 34A (shift lever 34) rotates about the axis of the support pin 32, and the shift lever 34 is disposed at each shift position.

The lower end of the shaft portion 34A is inserted into the guide groove 24B of the lower base 24. Specifically, the shaft portion 34A is disposed at the right end portion of the shift gate 24B3 at the position H of the shift lever 34. 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.

A pin holding portion 34B protruding from the shaft portion 34A in a substantially right-angled downward direction is provided at a lower end side portion of the shift lever 34, and the pin holding portion 34B is formed in a substantially bottomed cylindrical shape that is open to the lower side. A substantially round bar-shaped restraint pin 36 and an urging spring (not shown) are inserted into the pin holding portion 34B, and the restraint pin 36 is urged toward the distal end side by the urging spring. The tip of the restraint pin 36 is formed into a substantially hemispherical shape, and abuts against the stopper 24C of the lower base 24. The shift lever 34 is held at the H position by the stopper 24C and the restraint pin 36, and the stopper 24C is shaped to return the shift lever 34 to the H position when the shift lever 34 is operated to each shift position. When the shift lever 34 is operated to each shift position, the restraint pin 36 is slid on the stopper 24C, so that a restraining feeling (click feeling) is given to the shift lever 34.

Further, a second transmission shaft 34C is formed below the support pin 32 in a portion on the lower end side of the shift lever 34. The second transmission shaft 34C is formed in a substantially cylindrical shape with the front-rear direction as the axial direction, and protrudes forward from the shaft portion 34A. Thus, when the shift lever 34 rotates about the axis of the support pin 32, the distal end portion of the second transmission shaft 34C is displaced in the left-right direction.

(with respect to the position detecting mechanism 40)

As shown in fig. 1, 2, 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 that detects the shift position (operation position) of the shift lever 34. The position detection mechanism 40 includes a housing 50 as "external members", a first slider 60, a second slider 70, a link 80, a first magnet 100 and a second magnet 102, a substrate 110, and a housing cover 120.

(about the casing 50)

The housing 50 is formed in a substantially rectangular box shape open to the front side. The housing 50 is fastened and fixed to the front wall of the shift base 20 by a plurality of screws SC 1. Thus, the opening of the front side of the pawl housing groove portion 20H of the shift base 20 is closed by the bottom wall of the housing 50.

As shown in fig. 7 (a) and (B), a slider accommodating portion 51 for accommodating a first slider 60, which will be described later, is formed at the upper end portion of the housing 50 at a position corresponding to the first transmission shaft 30C of the lever holder 30. The slider housing portion 51 is formed in a substantially rectangular cylindrical shape whose vertical direction is the longitudinal direction and lateral direction is the width direction, and protrudes rearward from the bottom wall of the housing 50. The interior of the slider housing portion 51 penetrates in the front-rear direction, and the slider housing portion 51 opens upward.

As shown in fig. 2 and 7, a pair of left and right first slider supporting portions 52 are formed on the bottom wall of the upper end portion of the housing 50 on the rear side of the left and right side walls of the slider housing portion 51. The pair of first slider supporting portions 52 protrude rearward from the bottom wall of the housing 50 and extend in the up-down direction. The pair of first slider supporting portions 52 is disposed in the disposition hole 20C of the shift base 20. In the pair of first slider supporting portions 52, first slide grooves 52A are formed in the side surfaces facing each other in the left-right direction. The first slide groove 52A is open to the inside in the width direction (left-right direction) of the slider housing portion 51, and extends in the up-down direction, and the upper end portion of the first slide groove 52A is open to the upper side.

As shown in fig. 2 and 8, a pair of upper and lower second slider support portions 53 for mounting a second slider 70 to be described later are formed on the bottom wall of the housing 50 at positions corresponding to the second transmission shaft 34C of the shift lever 34. The second slider supporting portion 53 is formed in a substantially rectangular plate shape whose vertical direction is the plate thickness direction, protrudes rearward from the housing 50, and is disposed in the disposition hole 20C of the shift base 20. In the pair of second slider support portions 53, second slide grooves 53A extending in the left-right direction are formed in the surfaces facing each other in the up-down direction. The second slide groove 53A is open to the left and in the direction in which the second slider support portion 53 faces.

A link support shaft 54 for supporting a link 80 described later is formed on the bottom wall of the housing 50 between the pair of second slider support portions 53. The link support shaft 54 is formed in a substantially cylindrical shape with the front-rear direction as the axial direction, and protrudes forward from the bottom wall of the housing 50. As shown in fig. 6, a link insertion hole 55 is formed in the bottom wall of the housing 50 below the link support shaft 54. The link insertion hole 55 is formed in a long hole shape extending along the circumferential direction of the link support shaft 54.

A lower housing rib 56 is formed on the bottom wall of the housing 50 below the link support shaft 54. The lower case rib 56 extends in a substantially arc shape centering on the axial center of the link support shaft 54 when viewed from the front side, and projects forward from the bottom wall of the case 50. Further, a lower regulation portion 57 is formed below the link support shaft 54 at the tip end portion of the lower case rib 56. The lower restricting portion 57 extends from a tip end portion 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 lower restricting portion 57 extends in a substantially arc shape with the axial center of the link support shaft 54 as the center when viewed from the front side.

An upper case rib 58 is formed on the bottom wall of the case 50 above the link support shaft 54. The upper case rib 58 extends in a substantially arc shape centering on the axial center of the link support shaft 54 when viewed from the front side, and projects forward from the bottom wall of the case 50. An upper regulation portion 59 is formed above the link support shaft 54 at the tip end of the upper case rib 58. The upper regulating portion 59 extends from a tip end portion of the upper case rib 58 to a radially inner side (lower side) of the upper case rib 58, and extends in a substantially arc shape centering on the axial center of the support shaft 54 for the link as viewed from the front side, similarly to the upper case rib 58.

(with respect to the first slider 60)

As shown in fig. 2, 6, and 7, the first slider 60 is made of resin, and is formed in a substantially rectangular block shape whose vertical direction is the longitudinal direction and lateral direction is the width direction. A pair of left and right first slide rails 61 are formed on left and right side surfaces of a rear portion of the first slider 60, and the first slide rails 61 extend in the vertical direction. The first slider 60 is accommodated in the slider accommodating portion 51 of the housing 50 from above, and the pair of left and right first slide rails 61 is inserted into the first slide grooves 52A of the housing 50 so as to be slidable in the vertical direction. Thus, the first slider 60 is coupled to the housing 50 so as to be slidable in the vertical direction.

A coupling recess 62 (see fig. 7B) is formed in an upper portion of the first slider 60, and the coupling recess 62 is formed in a concave shape that opens to the rear side. The tip end portion of the first transmission shaft 30C of the lever holder 30 is inserted into the coupling recess 62 from the rear side, and is engaged with the inner peripheral surface of the coupling recess 62 in the vertical direction. Therefore, the following structure is obtained: when the shift lever 34 is operated in the shifting direction, when the lever holder 30 rotates about the axis of the holder rotation shaft 30A, the first slider 60 slides in the vertical direction by the first transmission shaft 30C in conjunction with the operation of the shift lever 34.

Further, a slider biasing spring 90 (see fig. 7B) configured as a compression coil spring is accommodated in the coupling recess 62. The slider biasing spring 90 is disposed between the bottom surface of the coupling recess 62 and the distal end portion of the first transmission shaft 30C, and biases the first slider 60 forward. Thereby, the following structure is formed: the first slide rail 61 abuts on the front surface of the first slide groove 52A of the housing 50, and determines the position of the first slider 60 in the front-rear direction with respect to the housing 50.

A first magnet housing portion 63 is formed at a lower portion of the first slider 60, and the first magnet housing portion 63 is formed in a concave shape that is open to the front side and is formed in a substantially rectangular shape whose vertical direction is the longitudinal direction when viewed from the front side. Further, engaging claws 64 are formed on the left and right side walls of the first magnet housing portion 63, respectively, and the engaging claws 64 are configured to be elastically deformable in the left and right direction. A hook portion 64A protruding inward in the width direction of the first slider 60 is formed at a distal end portion (distal end portion) of the engagement claw 64.

(with respect to the second slider 70)

As shown in fig. 2 and 8, the second slider 70 is formed in a substantially rectangular block shape and is disposed between the pair of upper and lower second slider supporting portions 53 of the housing 50. Second slide rails 71 are formed on the upper and lower surfaces of the second slider 70, respectively, and the second slide rails 71 extend in the left-right direction. The second slide rail 71 is inserted into the second slide groove 53A of the housing 50 so as to be slidable in the left-right direction. Thereby, the second slider 70 is coupled to the housing 50 so as to be slidable in the left-right direction.

A coupling groove 72 that opens to the rear side is formed in the rear portion of the second slider 70 at the left-right direction center portion, and the coupling groove 72 extends in the up-down direction. The second transmission shaft 34C of the shift lever 34 is inserted into the coupling groove 72, and is engaged with the inner peripheral surface of the coupling groove 72 in the left-right direction. Thereby, the following structure is formed: when the shift lever 34 is operated in the select direction, the second slider 70 slides in the left-right direction in conjunction with the operation of the shift lever 34 via the second transmission shaft 34C when the shift lever 34 rotates about the axis of the support pin 32.

A coupling cylinder portion 73 is formed at the front portion of the second slider 70 at the center portion in the left-right direction. The coupling cylinder portion 73 is formed in a substantially rectangular cylindrical shape having the longitudinal direction as the longitudinal direction and the longitudinal direction as the longitudinal direction, and the inside of the coupling cylinder portion 73 communicates with the inside of the coupling groove 72.

(about connecting rod 80)

As shown in fig. 6 and 8, the link 80 is made of resin and is formed in a substantially elongated rectangular block shape. A substantially bottomed cylindrical link pivot shaft 81 that opens to the rear side is formed at a longitudinal intermediate portion of the link 80. The link support shaft 54 of the housing 50 is fitted into the link pivot shaft 81, and the link pivot shaft 81 is rotatably supported by the link support shaft 54.

Further, a pair of

braking portions

82A, 82B protruding outward in the longitudinal direction of the link 80 are formed at both ends in the longitudinal direction of the link 80. The stopper 82A at one end in the longitudinal direction of the link 80 is disposed adjacent to the rear side of the lower limiting portion 57 of the housing 50, and the stopper 82B at the other end in the longitudinal direction of the link 80 is disposed adjacent to the rear side of the upper limiting portion 59 of the housing 50 (see fig. 6 and 8).

A link biasing spring 92 (see fig. 8) configured as a compression coil spring is accommodated in the link support shaft 54 of the housing 50. A spherical ball 94 (see fig. 8) is housed inside the link support shaft 54, and the ball 94 is disposed between the top wall of the link rotating shaft 81 of the link 80 and the link biasing spring 92. The ball 94 is pressed against the top wall of the link rotating shaft 81 by the biasing force of the link biasing spring 92. Thereby, the link 80 is biased forward by the link biasing spring 92, and the

stopper portions

82A and 82B of the link 80 come into contact with the lower limiting portion 57 and the upper limiting portion 59 of the housing 50. That is, the position of the link 80 in the front-rear direction with respect to the housing 50 is determined.

Further, an operating shaft 83 (see fig. 6) is formed at the longitudinal direction intermediate portion of the link 80. The operating shaft 83 is formed in a substantially cylindrical shape with the front-rear direction as the axial direction, and protrudes rearward from the link 80. The operating shaft 83 is disposed on one end side of the link 80 with respect to the link rotating shaft 81. The operating shaft 83 is inserted through the link insertion hole 55 of the housing 50, inserted into the coupling cylinder portion 73 of the second slider 70, and engaged with the inner circumferential surface of the coupling cylinder portion 73 in the left-right direction. Therefore, when the second slider 70 slides in the left-right direction, the link 80 is configured to rotate about the axis of the link rotating shaft 81. Specifically, the link 80 is disposed at an initial position (position shown in fig. 6) at the H position of the shift lever 34, and when the shift lever 34 is operated from the H position to the N position side, the link 80 rotates counterclockwise from the initial position as viewed from the front side.

A second magnet housing portion 84 is formed at one end portion in the longitudinal direction of the link 80. The second magnet housing portion 84 is formed in a concave shape open to the front side, and is formed in a substantially trapezoidal shape when viewed from the front side. In addition, an engagement claw 85 configured to be elastically deformable in the longitudinal direction of the link 80 is formed at a widthwise central portion of a side wall on one side in the longitudinal direction of the link 80 in the second magnet housing portion 84. Further, a hook portion 85A is formed at a distal end portion (distal end portion) of the engagement claw 85, and the hook portion 85A protrudes toward the other side in the longitudinal direction of the link 80 (the inner side of the second magnet housing portion 84).

Further, in the link 80, a magnet stopping portion 86 is formed in the second magnet housing 84 on the front side of the opening on the other end side of the link 80. The magnet stopping portion 86 extends in the width direction of the link 80, and both ends in the longitudinal direction of the magnet stopping portion 86 are connected to the side walls in the width direction of the second magnet housing portion 84.

(with respect to the first magnet 100)

As shown in fig. 2, 6, and 7, the first magnet 100 is formed in a substantially rectangular parallelepiped shape whose vertical direction is the longitudinal direction, corresponding to the first magnet housing portion 63 of the first slider 60. The first magnet 100 is accommodated in the first magnet accommodating portion 63 of the first slider 60. In addition, in a state where the first magnet 100 is accommodated in the first magnet accommodating portion 63, the hook portions 64A of the engaging claws 64 engage with the left and right front corner portions of the first magnet 100. Thereby, the first magnet 100 is held by the first slider 60, and is configured to move (slide) in the vertical direction integrally with the first slider 60.

(with respect to the second magnet 102)

As shown in fig. 2, 6, and 8, the second magnet 102 is formed in a substantially trapezoidal block shape corresponding to the second magnet housing portion 84 of the link 80 when viewed from the front side. Specifically, the length in the width direction of one end portion (lower end portion) of the second magnet 102 is set longer than the length in the width direction of the other end portion (upper end portion) of the second magnet 102. Further, magnet-side chamfered portions 102A are formed at rear-side corners of one end portion and the other end portion of the second magnet 102, respectively (see fig. 8). The second magnet 102 is accommodated (fitted) in the second magnet accommodating portion 84 of the link 80. In a state where the second magnet 102 is accommodated in the second magnet accommodating portion 84, the hook portion 85A of the engaging pawl 85 engages with a corner portion on the front side of one end portion of the second magnet 102, and the magnet stopping portion 86 is disposed adjacent to the front side of the other end portion of the second magnet 102 (see fig. 8). Thereby, the second magnet 102 is held by the link 80, and is configured to rotate integrally with the link 80.

The second magnet 102 is disposed on one end side of the link 80 with respect to the operating shaft 83. Therefore, the following settings are made: when the link 80 rotates, the amount of rotation of the second magnet 102 is larger than the amount of rotation of the operating shaft 83. That is, the link 80 is configured as a member that amplifies the movement amount of the second magnet 102 with respect to the movement amount of the shift lever 34.

(with respect to the substrate 110)

As shown in fig. 2, the substrate 110 is formed in a substantially rectangular plate shape with the front-rear direction being the plate thickness direction. The base plate 110 is housed in the case 50 on the front side with respect to the link 80 and the first slider 60, and is fastened and fixed to the case 50 by a screw SC 2. At the front surface of the substrate 110, a connector 112 is provided at a portion on the left side. A vehicle connector is connected to the connector 112, and the board 110 is electrically connected to a control unit (not shown) of the vehicle.

As shown in fig. 7 (a) and (B), a first hall IC114 is provided on the front side of the first magnet 100 on the rear surface (one side surface) of the substrate 110. As shown in fig. 6 and 8, four second hall ICs 116 are provided on the rear surface of the substrate 110. Two second hall ICs 116 are disposed on the front side of the second magnet 102, and when the shift lever 34 is operated to the N position, two other second hall ICs 116 are disposed on the front side of the second magnet 102. The first hall IC114 (second hall IC116) 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. Then, the control portion detects the shift position of the shift lever 34 based on the output values from the first hall IC114 and the second hall IC 116.

As shown in fig. 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 material, is disposed with the front-rear direction being the plate thickness 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 SC 2.

(about the case cover 120)

The housing cover 120 is formed in a substantially rectangular box shape that is open to the rear side. The housing cover 120 is fixed to the housing 50 by fitting with a claw so as to cover the opening of the housing 50.

(fixing structure for lower base 24)

Next, a structure for fixing the lower base 24 to the shift base 20 will be described. As shown in fig. 4, a pair of right and left locking portions 24A is formed at the rear end of the lower base 24. The locking portion 24A extends upward from the lower base 24, and an upper end of the locking portion 24A protrudes rearward. The upper end of the locking portion 24A is inserted into the locking hole 20D of the shift base 20, and the locking portion 24A is locked to the shift base 20. Specifically, since the lower base 24 is pushed downward by the restraint pin 36 and the biasing spring of the shift lever 34, the upper end portion of the locking portion 24A is locked to the inner peripheral surface of the lower side of the locking hole 20D of the shift base 20, and the rear end portion of the lower base 24 is fixed to the shift base 20.

As shown in fig. 10, a pair of left and right fixing walls 24D are formed at the front end of the lower base 24. The fixing wall 24D is formed with the thickness direction in the left-right direction, and protrudes upward from both end portions in the left-right direction of the lower base 24. The pair of fixing walls 24D are disposed inside the lower end portion of the shift base 20, and are disposed adjacent to the left and right inner sides of the left and right side walls of the shift base 20 in the left-right direction.

A first fixed-subject hole 24E, which is a "fixed-subject hole" having a circular shape, is formed through the right-hand fixing wall 24D in the left-right direction. The first fixed hole 24E is disposed coaxially with the first support hole 20F of the shift base 20, and the diameter of the first fixed hole 24E and the diameter of the first support hole 20F are set to be the same size.

A second fixed-subject hole 24F, which is a "fixed-subject hole" in a circular shape, is formed through the left-hand fixed wall 24D in the left-right direction. The second fixed hole 24F is disposed coaxially with the second support hole 20G of the shift base 20, and the diameter of the second fixed hole 24F and the diameter of the second support hole 20G are set to be the same size.

The front end portion of the lower base 24 is fixed to the shift base 20 by a pin 26. The structure of the pin 26 will be explained below. As shown in fig. 9 and 10, the pin 26 is made of resin, and is formed in a substantially cylindrical shape with the left-right direction as the axial direction as a whole. Specifically, the pin 26 includes: a substantially cylindrical pin body 27 extending in the left-right direction; a flange 28 formed at the right end (one end) of the pin main body 27; and a fixing claw 29 extending from the flange 28 to the left side (the other end side of the pin main body 27).

The diameter of the right end of the pin body 27 is set to be slightly smaller than the diameter of the first hole 24E of the lower base 24, and the diameter of the left end of the pin body 27 is set to be slightly smaller than the diameter of the second hole 24F of the lower base 24. That is, the diameter of the right end portion of the pin main body 27 is set larger than the diameter of the left end portion. Further, a stepped portion 27A that is raised one step radially outward from the left end portion of the pin main body 27 is formed in a portion on the left end portion side of the pin main body 27. The pin body 27 is inserted into the first support hole 20F of the shift base 20 from the right side, and is bridged on the left and right side walls of the shift base 20. Specifically, the right end portion of the pin body 27 is inserted into the first support hole 20F of the shift base 20 and the first fixed hole 24E of the lower base 24, and the left end portion of the pin body 27 is inserted into the second support hole 20G of the shift base 20 and the second fixed hole 24F of the lower base 24. Thereby, the lower base 24 is fixed to the shift base 20 by the pin 26.

The flange 28 is formed in a substantially elliptical plate shape with the plate thickness direction being the left-right direction, corresponding to the flange receiving portion 20E of the shift base 20, and projects radially outward from the right end of the pin body 27. The flange 28 is accommodated in the flange accommodating portion 20E. Thus, the movement of the pin 26 to the left is restricted by the flange 28.

The fixing claws 29 are formed in a substantially rectangular plate shape whose plate thickness direction is the front-rear direction and whose longitudinal direction is the left-right direction. The right end of the fixing claw 29 is bent to the rear side and connected to the front end of the flange 28. Thus, the fixing claws 29 are configured to be elastically deformable in the front-rear direction (the direction in which the shift base 20 faces the housing 50). The fixing pawls 29 are accommodated in the pawl accommodating groove portions 20H of the shift base 20. That is, the fixing pawls 29 are sandwiched by the shift base 20 and the housing 50 in the front-rear direction. A hook portion 29A protruding rearward is formed at a distal end portion (left end portion) of the fixed pawl 29, and the hook portion 29A is inserted into the engagement hole 20J of the shift base 20 and engaged with the inner peripheral surface on the right side of the engagement hole 20J. Thus, the movement of the pin 26 to the right side is restricted by the hook 29A.

(operation of the shift lever 34)

In the shift lever device 10 configured as described above, when the shift lever 34 is operated in the shifting direction (front-rear direction), the shift lever 34 rotates together with the lever holder 30 about the axis of the holder rotating shaft 30A of the lever holder 30. Thereby, the tip end portion of the first transmission shaft 30C of the lever holder 30 is displaced in the vertical direction.

When the first transmission shaft 30C is displaced in the vertical direction, the first slider 60 coupled to the first transmission shaft 30C slides in the vertical direction. Thereby, the first magnet 100 is displaced in the vertical direction together with the first slider 60. As a result, the first hall IC114 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.

Further, when the shift lever 34 is operated in the gear selection direction (left-right direction), the shift lever 34 rotates about the axis of the support pin 32. Thereby, the distal end portion of the second transmission shaft 34C of the shift lever 34 is displaced in the left-right direction.

When the second transmission shaft 34C is displaced in the left-right direction, the second slider 70 coupled to the second transmission shaft 34C slides in the left-right direction. Thereby, the link 80 coupled to the second slider 70 rotates about the axis of the link rotating shaft 81. Therefore, the second magnet 102 rotates together with the link 80 about the axis of the link rotating shaft 81. As a result, the second hall IC116 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 detects the shift position of the shift lever 34 based on the output values from the first hall IC114 and the second hall IC 116.

(Effect)

Next, the assembly procedure when the lower base 24 is assembled to the shift base 20 will be described, and the operation and effect of the present embodiment will be described.

When the lower base 24 is assembled to the shift base 20, the lower base 24 is disposed below the shift base 20. Then, the locking portions 24A of the lower base 24 are inserted into the locking holes 20D of the shift base 20, and the fixing wall 24D of the lower base 24 is inserted into the lower end portion of the shift base 20 from below. Then, the first fixed hole 24E and the second fixed hole 24F of the lower base 24 are arranged coaxially with the first support hole 20F and the second support hole 20G of the shift base 20.

In this state, the pin body 27 of the pin 26 is inserted into the first support hole 20F of the shift base 20 from the right side, and the pin 26 is assembled to the shift base 20. Specifically, the pin main body 27 is inserted into the first support hole 20F of the shift base 20 and the first fixed hole 24E of the lower base 24, and is inserted into the second support hole 20G of the shift base 20 and the second fixed hole 24F of the lower base 24.

Further, at the final stage of assembling the pin 26 to the shift base 20, the fixing claws 29 of the pin 26 are inserted into the claw receiving groove portions 20H of the shift base 20. When the fixing claws 29 are inserted into the claw receiving groove portions 20H, the hook portions 29A of the fixing claws 29 are pressed forward by the bottom surfaces of the claw receiving groove portions 20H, and the fixing claws 29 are elastically deformed forward. Then, flange 28 of pin 26 is accommodated in flange accommodating portion 20E of shift base 20 and brought into contact with the bottom surface of flange accommodating portion 20E, thereby completing assembly of pin 26 to shift base 20.

When the assembly of pin 26 to base 20 is completed, hook portion 29A of fixing pawl 29 is inserted into engagement hole 20J of shift base 20, and fixing pawl 29 is elastically deformed to its original state. Thus, the fixed pawl 29 is accommodated in the pawl accommodation groove portion 20H of the shift base 20, and the movement of the pin 26 to the right side is regulated by the hook portion 29A of the fixed pawl 29. After the pin 26 is assembled to the shift base 20, the position detection mechanism 40 is fixed to the shift base 20, and the front opening of the pawl housing groove portion 20H is closed by the case 50 of the position detection mechanism 40.

As described above, in the present embodiment, the pin main body 27 of the pin 26 is inserted through the first and second support holes 20F and 20G of the shift base 20 and the first and second fixed

holes

24E and 24F of the lower base 24. Further, flange 28 constituting the right end portion of pin main body 27 abuts against the bottom surface of flange housing portion 20E of shift base 20, and movement of pin 26 to the left side is restricted. Further, the fixing pawl 29 of the pin 26 extending leftward from the flange 28 is configured to be elastically deformable in the front-rear direction, the hook portion 29A of the fixing pawl 29 engages with the engagement hole 20J of the shift base 20, and movement of the pin 26 to the right side is restricted. Thus, the pin 26 can be assembled to the shift base 20 without using another member such as a push nut described in the background art. Therefore, the ease of assembling the pin 26 to the shift base 20 can be improved.

Further, the fixing claws 29 are arranged between the shift base 20 and the housing 50 of the position detecting mechanism 40. Thus, after the lower base 24 is assembled to the shift base 20, the housing 50 is fixed to the shift base 20, whereby the fixing pawls 29 are sandwiched by the shift base 20 and the housing 50 in the front-rear direction. Therefore, the housing 50 can prevent the fixed pawls 29 engaged with the shift base 20 from being displaced (deformed) toward the front side. That is, the case 50 can prevent the hook portion 29A of the fixing pawl 29 from being disengaged from the engagement hole 20J. Therefore, the assembled state of the pin 26 to the shift base 20 can be maintained satisfactorily.

A flange receiving portion 20E that is open to the right is formed on the right wall of shift base 20, and flange 28 of pin 26 is received in flange receiving portion 20E. A pawl housing groove portion 20H opened to the front side is formed in the front wall of the shift base 20, and the fixed pawl 29 of the pin 26 is housed in the pawl housing groove portion 20H. Therefore, the pin 26 can be assembled from the right side of the shift base 20 using the flange receiving portion 20E and the pawl receiving groove portion 20H as marks. That is, the pin 26 can be prevented from being assembled from the left side of the shift base 20. This can prevent erroneous assembly of the pin 26.

In addition, the diameter sizes of the right and left end portions of the pin main body 27 are set to different sizes. Specifically, the diameter of the right end of the pin body 27 is set larger than the diameter of the left end. This prevents the pin 26 from being assembled from the left side of the shift base 20. That is, when the pin 26 is assembled from the left side of the shift base 20, the stepped portion 27A of the pin main body 27 abuts against the edge of the second support hole 20G of the shift base 20, and the pin 26 is prevented from moving to the left side. This prevents the pin 26 from being assembled from the left side of the shift base 20. Therefore, in this regard, the erroneous assembly of the pin 26 can also be prevented.

Further, the lower base 24 is formed with a guide groove 24B for guiding the movement of the shift lever 34. Thus, the lower base 24 that guides the movement of the shift lever 34 can be fixed to the shift base 20 with a simple configuration.

Further, a stopper portion 24C is formed on the lower base 24, and the stopper portion 24C is used to give a feeling of constraint when the shift lever 34 is operated. Thus, the lower base 24 that gives the shift lever 34a feeling of restraint can be fixed to the shift base 20 with a simple structure.

The housing 50 that regulates the forward deformation of the fixing claws 29 of the pins 26 is configured as a member that constitutes the outer contour of the position detection mechanism 40. Therefore, the housing 50 (position detection mechanism 40) for detecting the shift position of the shift lever 34 can be flexibly used to restrict the deformation of the fixing claws 29 of the pins 26 to the front side, and the assembled state of the pins 26 to the shift base 20 can be satisfactorily maintained.

In the present embodiment, hook portions 29A are formed on fixing claws 29 of pins 26, and engagement holes 20J that engage with hook portions 29A are formed in shift base 20. Instead, a hook portion protruding forward may be formed on the bottom surface of the pawl housing groove portion 20H of the shift base 20, and an engagement hole with which the hook portion is engaged may be formed in the fixed pawl 29 of the pin 26.

In the present embodiment, the flange receiving portion 20E and the pawl receiving groove portion 20H are formed in the shift base 20, but the flange receiving portion 20E and the pawl receiving groove portion 20H may be omitted from the shift base 20. In this case, the flange 28 of the pin 26 may be disposed adjacent to the right side surface of the shift base 20, the fixing claw 29 of the pin 26 may be disposed adjacent to the front surface of the shift base 20, and a recess for disposing the fixing claw 29 may be formed in the housing 50.

In the present embodiment, the diameter sizes of the right end portion and the left end portion of the pin 26 are set to be different, but the diameter of the pin 26 may be set to be constant in the entire longitudinal direction.
