[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever device for an automatic transmission of an automobile, and more particularly to a shift lever device for a gate type automatic transmission capable of shifting the shift lever in the longitudinal direction of the vehicle and in the width direction of the vehicle. Regarding the structure.

2. Description of the Related Art A shift lever device for an automatic transmission includes a straight-type shift lever device in which the shift lever can shift only in the vehicle front-rear direction, and a gate-type shift lever device in which the shift lever can shift in the vehicle front-rear direction and the vehicle width direction. Shift lever device.

FIG. 41 shows an example of a conventional shift lever device for a gate type automatic transmission. As shown in FIG. 41, the shift lever 1 can be positioned in the P, R, N, D, 3, 2, and L ranges, respectively. P 'indicates the process of shifting the shift lever 1 from the P range to another range. In a vehicle, it is necessary to detect in which range the shift lever is located in relation to running control or the like. For the R, N, 2 and L ranges, a transmission (not shown) interlocked with the movement of the shift lever 1 Side can detect.

On the other hand, a shift operation between the P range and the P 'range and a shift operation between the D range and the 3 range cannot be detected on the transmission side. This is because the movement of the shift lever 1 in the vehicle longitudinal direction is transmitted to the transmission, but the movement of the shift lever 1 in the vehicle width direction is not transmitted to the transmission. Therefore, the conventional gate-type shift lever device is provided with position detection switches 2 and 3 for detecting the shift operation of the shift lever 1 to the P range and the shift operation to the three ranges, as shown in FIGS. Have been.

[0005]

However, in the conventional gate-type shift lever device, since the position detection switches are provided independently of each other, the wiring harness (electric wire) is not provided.
In addition, there is a problem that costs including connectors (connection terminals) are increased. As shown in FIG. 44, the position detection switches 2 and 3 are provided between an upper base 5 provided immediately above a lower base to which the shift lever 1 is attached and an upper housing 6 that covers the upper base 5. Therefore, the distance H between the upper base 5 and the upper housing 6 increases, and the upper base 5 to which a detent plate (not shown) with which the shift lever 1 is engaged is attached when shifting the shift lever 1 is large. A force acts, resulting in a structure disadvantageous in strength. This is because the height of the upper housing 6 and the length of the shift lever 1 cannot be changed due to the design and operability of other interior parts, and if the position detection switches 2 and 3 are provided, On the other hand, the height of the upper base 5 must be lowered,
This is because the distance between the fulcrum and the point of action (detent plate) is significantly shorter than the distance between the fulcrum (the pivot center of the shift lever) and the power point (the top of the shift lever).

SUMMARY OF THE INVENTION It is an object of the present invention to provide a shift lever device for an automatic transmission in which the number of switches for detecting the position of the shift lever can be reduced and the detent portion on which the operating force of the shift lever acts can have a structure advantageous in strength.

And the second engagement portion of the switch drive link,
Since the holder can be engaged with the holder of the position detection switch, the holder can be moved by shifting the shift lever, and the moving contact moves due to the movement of the holder. Here, when the shift lever is positioned in the P range, the moving contact contacts the first fixed contact, and it is detected that the shift lever exists in the P range. Similarly, in a state where the shift lever is positioned in a specific range (for example, 3 ranges) other than the P range,
The moving contact contacts the second fixed contact and the shift lever
It is detected that it is in the range. Since each fixed contact is provided on the same position detection switch, only one position detection switch is required, and the number of position detection switches can be reduced compared to the conventional device. Since the position detection switch is provided on the outer peripheral portion of the upper base, it is not necessary to significantly lower the height of the upper base with respect to the upper housing. Therefore, a large distance can be secured between the swing fulcrum of the shift lever and the upper base to which the detent portion serving as the action point is attached, and the upper base on which the shift lever operating force acts is advantageous in strength. Becomes In the shift lever device for an automatic transmission according to the above (2), when the shift lever is shifted toward the P range, the first projection of the boss portion presses the first positioning surface of the switch drive link.

When the shift lever is positioned in the P range, the moving contact of the position detection switch contacts the first fixed contact, and it is detected that the shift lever is in the P range. When the shift lever is shifted to position the shift lever in a specific range (for example, three ranges) other than the P range, the second projection of the boss presses the second positioning surface of the switch drive link. With the movement of the shift lever, the switch drive link swings, for example, by a predetermined angle in the reverse direction, and the holder connected to the switch drive link moves. When the shift lever is positioned in three ranges, the moving contact of the position detection switch contacts the second fixed contact, and it is detected that the shift lever exists in three ranges. Since each fixed contact is provided on the same position detection switch, only one position detection switch is required, and the number of position detection switches can be reduced compared to the conventional device. Since the position detection switch is provided on the outer periphery of the base plate portion, it is not necessary to greatly reduce the height of the detent portion for positioning the shift lever. Therefore, a large distance can be secured between the swinging fulcrum of the shift lever and the detent portion serving as an action point, and the detent portion on which the operating force of the shift lever acts is advantageous in strength. In the shift lever device for an automatic transmission according to the above (3), when the shift lever is shifted to the P range, the shift lever presses the first cam surface of the switch drive rod. Moves in a predetermined direction. Accordingly, the holder connected to the switch drive rod also moves, and it is possible to detect that the shift lever has been shifted to the P range by the contact between the moving contact and the first fixed contact. When the shift lever is shifted to a specific range (for example, three ranges) other than the P range, the shift lever is moved to the second position of the switch drive rod.
, The switch drive rod can be moved in the direction opposite to the predetermined direction by this pressing force. Therefore, the holder connected to the switch drive rod also moves in the opposite direction, and it is detected that the shift lever has been shifted to three ranges by the contact between the moving contact and the second fixed contact. Since each fixed contact is provided on the same position detection switch, only one position detection switch is required as in the above-mentioned claim. Further, since the position detection switch is provided on the outer peripheral portion of the base plate portion, the detent portion is advantageous in strength as in the above-described claims.

1 to 10 show a shift lever device for an automatic transmission according to a first embodiment of the present invention. In FIG. 1, reference numeral 20 denotes a lower base fixed to a vehicle body (not shown). The lower base 20 is formed with a support hole 23 into which the shaft 22 to which the connecting lever 21 is attached is inserted. The connection lever 21 is swingable about the shaft 22 in the vehicle front-rear direction. The lower end of the connecting lever 21 is connected to a vehicle transmission (not shown) via a rod (not shown). Immediately above the lower base 20, an upper base 26
Is arranged. The leg of the upper base 26 is fastened to the lower base 20 by a nut 25 that is screwed with a screw 24 provided on the lower base 20.

A shift lever 30 is connected to a shaft 22 of a connecting lever 21 swingably supported by the lower base 20. The lower end 31 of the shift lever 30 is inverted U
It is formed in a character shape and straddles the shaft 22.
The lower end 31 is connected to the shaft 22 via a connecting pin (not shown) penetrating the shaft 22. The shift lever 30 has a rod 32 extending upward from a lower end 31. The rod 32 has a knob 33 on the top. In the vicinity of the lower end 31 where the rod 32 is fixed, a plate-like arm 34 extending horizontally in the front-rear direction of the vehicle is formed. At the tip of the arm 34, a U-shaped first
Are formed. At a position of the lower end portion 31 adjacent to the first engagement portion 35, a boss portion 36 extending horizontally in the vehicle width direction is formed.

The shift lever 30 is swingable about the shaft 22 in the vehicle front-rear direction (arrow X direction). The movement of the shift lever 30 in the vehicle longitudinal direction is transmitted to the connecting lever 21 via the shaft 22. The shift lever 30 can swing in the vehicle width direction (arrow Y direction) around a connection pin (not shown) that passes through the shaft 22. The movement of the shift lever 30 in the vehicle width direction is not transmitted to the shaft portion 22 and the connecting lever 21.

At the top of the upper base 26, a step-like long hole 28 through which the rod 32 of the shift lever 30 is inserted is formed. A detent plate 40 as a detent portion is attached to the top surface of the upper base 26. The detent plate 40 is formed with a positioning step 41 having a step-like shape similar to the elongated hole 28. Except for the D range, the shift lever 30 is configured such that the rod 32 always contacts the positioning step portion 41 of the detent plate 40 by a spring (not shown). The shift lever 30 is engaged with the upper base 26 by a detent mechanism (not shown) in the D range, and is positioned at a position separated from the positioning step 41 of the detent plate 40 in the vehicle width direction. The disengagement between the moderation mechanism and the upper base 26 can be released by simply moving the shift lever 30 in the vehicle width direction.

The shift lever 30 can be positioned in the P range, R range, N range, D range, 3 range, 2 range, and L range by the detent plate 40, respectively. The P range is used when the vehicle parks and stops, and the R range is used when the vehicle retreats. The N range is a neutral range, in which the rotational driving force of the engine is not transmitted to the wheels. The D range is a drive range, and is 1 according to the depression amount of an accelerator pedal (not shown).
The speed ratio is automatically selected from any of the fourth to fourth speeds. The three ranges are used in a fixed range of the first to third speeds of the D range, and the second range are used in a fixed range of the first to second speeds of the D range. Note that P 'indicates a simple passing point of the shift lever 30, and the shift lever 30 is not positioned here.

A mounting pedestal 46 extending in the front-rear direction of the vehicle is formed on the outer periphery of the upper base 26. A position detection switch 52 integrated with the solenoid 50 is fixed to the mounting base 46. The position detection switch 52 is mounted on the solenoid 50 so as to overlap with the solenoid 50, and the solenoid 50 is fastened to the mounting base 46 with screws or the like. When the shift lever 30 is in the P range, its movement is locked by a shift lock mechanism (not shown), so that a shift operation to another range cannot be performed unless a brake pedal (not shown) is depressed. ing. The solenoid 50 is excited when a brake pedal (not shown) is depressed while the shift lever 30 is in the P range, and releases the shift lock of the shift lever 30.

In this embodiment, the position detection switch 52 is located at the front of the upper base 26 in the vehicle traveling direction. The shift lever device having the position detection switch 52 at this position is a FR (front engine / rear drive).
Suitable for vehicles of the type. This is because the FR type vehicle has an engine mounted vertically and an automatic transmission (not shown) is arranged on the floor side, so that a rod (not shown) for transmitting the movement of the shift lever 30 is located below the floor of the automobile. And is connected to the automatic transmission outside the vehicle cabin.
Is not in the way even if it is arranged at the above position.

The position detecting switch 52 has a case 53, a lever 54, a holder 55, a moving contact 56, a first fixed contact 57, and a second fixed contact 58. Lever 54
Are housed in a case 53 and can swing horizontally about a fulcrum 59. The lever 54 has a holding hole 54a. A holder 55 is slidably mounted in the holding hole 54a. Lever 5
A moving contact 56 is attached to the front end of 4. The shift lever 30 is provided on both sides of the lever 54 in the case 53.
A first fixed contact 57 for detecting that is in the P range;
A second fixed contact 58 for detecting that the shift lever 30 is in three ranges is provided. The first fixed contact 57 is made up of two metal terminals, and the two metal terminals are made conductive by the moving contact 56. The second fixed contact 58 is composed of two metal terminals, and the two metal terminals are made conductive by the moving contact 56.

A shaft 60 extending upward is formed on the outer surface of the corner of the upper base 26. An L-shaped switch drive link 61 is supported on the shaft 60 so as to be swingable in the horizontal direction. The switch drive link 61 is connected to the shaft 6
0, and a fulcrum 62 extending from the fulcrum 62
It has two arms 63 and 64. One arm 63
A cam surface 65 that can abut the boss 36 of the shift lever 30 is formed at an end of the shift lever 30. At the end of the other arm 64, a U-shaped second engaging portion 66 that can engage with the holder 55 of the position detection switch 52 is formed. The holder 55 can also engage with the first engaging portion 35 of the shift lever 30. The upper part of the upper base 26 is covered with an upper housing 70. The upper housing 70 is fixed to the upper base 26 by engaging the engaging pieces 71 with the engaging portions 72 of the upper base 26.

The switch drive link 61 is covered by a housing upper 70. The switch drive link 61 is urged in a direction in which the arm 63 approaches the shift lever 30 side by a spring 74 arranged on the outer periphery of the fulcrum 62. Holder 5 of position detection switch 52
5 is inserted into a cross-shaped guide hole 53a formed in the case 53, and the holder 55 is inserted into the guide hole 53.
a to move in the horizontal direction. When the shift lever 30 swings in the vehicle width direction and the arm portion 34 or the switch drive link 61 engaged with the holder 55 moves, the lever 54 of the position detection switch 52 swings in accordance with the movement. Moves forward and backward with respect to each of the fixed contacts 57 and 58.

Next, the operation of the first embodiment will be described. As shown in FIG. 6, when the shift lever 30 is in the P range, the first engagement portion 3 of the shift lever 30
5 and the second engagement portion 66 of the switch drive link 61 are engaged with the holder 55 of the position detection switch 52, so that the holder 55 is drawn toward the P range. In this state, the lever 54 swings toward the first fixed contact 57, and the two metal terminals of the first fixed contact 57 are conductive through the moving contact 56. Therefore, it is possible to electrically confirm that the shift lever 30 is in the P range.

When the vehicle is started, the solenoid 50 is excited by depressing a brake pedal (not shown), and the shift lock of the shift lever 30 is released. As shown in FIG. 7, when the shift lever 30 is shifted to the position P ', the holder 55 engaged with the first engagement portion 35
Moves away from the P range. Therefore, the lever 54 provided with the moving contact 56 swings, and the moving contact 5
6 moves away from the first fixed contact 57. Therefore, the first
The two metal terminals of the fixed contact 57 are in a non-conductive state. Note that the fact that the shift lever 30 is at the P 'position is grasped on the transmission side interlocked with the movement of the shift lever 30.

FIG. 8 shows a state where the shift lever 30 is shifted to the D range. In this case, the movement of the shift lever 30 in the vehicle front-rear direction causes the holder 55 and the first
Is disengaged from the engaging portion 35, and only the holder 55 and the second engaging portion 66 are engaged. Therefore, the moving contact 56 remains separated from the first fixed contact 57, and the two metal terminals of the first fixed contact 57 become non-conductive. The fact that the shift lever 30 is in the D range is grasped on the transmission side as described above.

FIG. 9 shows a state where the shift lever 30 is shifted to three ranges. When the shift lever 30 is shifted from the D range to the third range, the boss portion 36 of the shift lever 30 abuts against the cam surface 65 of the switch drive link 61, and the switch drive link 61 becomes the center of the fulcrum portion 62 in the arrow Z direction. Rocks. The holder 55 of the position detection switch 52 is
The lever 54 also swings with the swing of the switch drive link 61.
Therefore, the moving contact 56 contacts the second fixed contact 58, and the two metal terminals of the second fixed contact 58 are connected to the moving contact 5.
6 are conducted. Therefore, shift lever 3
It is possible to electrically confirm that 0 is in the three ranges.

FIG. 10 shows a state where the shift lever 30 is shifted to two ranges. Since the cam surface 65 of the switch drive link 61 is an inclined surface whose end gradually moves away from the shift lever 30, the shift lever 3
When 0 moves to two ranges, the contact between the boss portion 36 of the shift lever 30 and the cam surface 65 is avoided. Therefore, the switch drive link 61 swings toward the shift lever 30 by the urging force of the spring 74, and the holder 55 engaged with the second engagement portion 66 is in the state of FIG.
Therefore, the moving contact 56 does not contact either the first fixed contact 57 or the second fixed contact 58, and the two metal terminals of each fixed contact 57, 58 are in a non-conductive state.

In the conventional device, the position detection switch for detecting the shift position of the shift lever is mounted on the upper surface of the detent plate provided on the top surface of the upper base, so that the position of the upper base is lower than that of the upper housing. In this embodiment, the position detection switch 5
2 is provided on the outer periphery of the upper base 26, so that the upper base 26 to which the detent plate 40 is attached is provided.
It is no longer necessary to reduce the height of the object. Thereby, a large distance between the swing fulcrum of the shift lever 30 and the detent plate 40 serving as an action point can be secured. Therefore, the force acting on the upper base 26 when the shift lever 30 and the detent plate 40 are in contact with each other is reduced, and the upper base 26 has a structure that is advantageous in strength.

In this embodiment, since the position detection switch 52 is integrated with the solenoid 50 for releasing the shift lock, the length of the wire harness (wire) and the number of connectors for connecting the wire harness are reduced. It is also possible to reduce. Further, since the position detection switch 52 and the electric component such as the solenoid 50 are disposed adjacent to each other, the work of connecting the wire harness is also facilitated.

A holding groove 142 is formed on one side of the slider 141 so as to always engage with the holder 55 of the position detection switch 52 in the vehicle front-rear direction. On the other side of the slider 141, an engagement groove 143 into which a second flange 139 formed on the shift lever 85 can enter is formed. The engagement groove 143 of the slider 141 engages with the second flange 139 when the shift lever 85 is shifted from the D range to the M range. Shift lever 85
Is shifted to the M range, the shift lever 85

Is electrically connected to the automatic transmission. The automatic transmission switches the gear ratio in response to a command signal from a shift command detecting means 150.

Next, the operation of the third embodiment will be described. In a state where the shift lever 85 is shifted to the P range, the first positioning surface 115 of the switch drive link 110 is pressed by the first projection 101 of the boss portion 90, and the switch drive link 110 swings.
Therefore, the holder 55 of the position detection switch 52 is
It is positioned at the position F ₁ of 9, by contact with the first fixed contact 57 and moving contact 56, the shift lever 85 can be electrically detected that there is the P range. When the shift lever 85 is shifted from the D range to the M range, the second protrusion 102 is connected to the switch drive link 11.
Since the second positioning surface 116 is pressed, the switch drive link 110 swings. Thus, the holder 55 of the position detecting switch 52 is positioned at the position F ₂ in FIG. 19, by contact between the moving contact 56 and the second fixed contact 58, the shift lever 85 is electrically detected that in M range be able to.

When the shift lever 85 is shifted from the D range to the M range, the engagement between the first flange 133 and the engagement hole 134 is released by the swing of the shift lever 85 in the vehicle width direction. In this state, since the ball 138 is engaged with the moderation groove on the base plate 80 side, the control lever 131 is not moved to the M range side and is held at the same position. Further, since the second flange 139 of the shift lever 85 enters the engagement groove 143 of the slider 141, the shift lever 85 and the slider 141 are engaged with each other in the vehicle front-rear direction.

When the shift lever 85 is shifted to the M range, as shown in FIG.
Moving the + in position, the holder 55 of the position detecting switch 52 is moved to the position X _1, by the operation of shift command detecting means 150, the signal is output to the automatic transmission. As a result, the gear ratio of the automatic transmission is switched to the high speed side. As shown in FIG. 21, when the shift lever 85 is moved to the-position,
Holder 55 of the position detecting switch 52 is moved to the position X _2, by the operation of shift command detecting means 150, another signal in the automatic transmission is output. Thereby, the gear ratio of the automatic transmission can be switched to the low speed side.

In the M range, for example, when the gear ratio is switched to the fourth speed, the shift can be switched to the second speed by moving the shift lever 85 to the minus side twice. When the shift lever 85 moves to the + side or the − side, the ball 94 attached to the shift lever 85 is pressed against the slope provided on the base plate 80, and a force is applied to the shift lever 85 to return to the M position. I do. Therefore, after the shift operation, the shift lever 85 always returns to the M position. When the shift lever 85 moves to the + or-position, the switch drive link 110 is connected to the shift lever 8.
It keeps the same posture as the state where 5 is shifted to the M range. In the first and second embodiments, the switch drive link is swingable in the horizontal direction.

FIGS. 38 to 40 show a fifth embodiment of the present invention, and correspond to claim 3. Since a part of the configuration of the present embodiment is in accordance with the second embodiment, the same reference numerals are given to the corresponding portions, and the description of the corresponding portions will be omitted, and only different portions will be described. As shown in FIG. 39, a switch drive rod 301 extending along the outer surface of the base plate 80 is arranged on the outer periphery of the base plate 80. The switch drive rod 301 is composed of a square rod member extending linearly. The switch drive rod 301 is slidably held by a support 310 provided on the base plate 80 side. The switch drive rod 301 is
It is movable only in the vehicle front-rear direction (X direction).

As shown in FIG. 38, a pair of flange portions 312 are formed on the boss portion 90 of the shift lever 85. A roller 313 is rotatably supported by the flange portion 301. A pair of engagement protrusions 306 are formed on the surface of the switch drive rod 310 opposite to the surface facing the roller 313. Each engagement protrusion 306 is engaged with an end of a torsion spring 321 held on a fulcrum 320 formed on the base plate 80 side. Both ends of the torsion spring 321 are also in contact with stoppers 322 formed on the base plate 80 side. Switch drive rod 301 is always biased to return to a neutral position F ₀ by the torsion spring 321.

Roller 3 of switch drive rod 301
A cam 302 protruding toward the roller 313 is provided at a position opposing the cam 13. On one side of the cam 302, a first cam surface 303 formed of an inclined surface is formed. On the other side of the cam 302, a second cam surface 304 inclined in a direction opposite to the first cam surface 303 is formed. The shift operation to the P range of the shift lever 85, the roller 313 upon pressing the first cam surface 303, the switch drive rod 301 moves in the arrow X ₄ direction. When the roller 313 pushes the second cam surface 304 by the shift operation of the shift lever 85 to the three ranges, the switch drive rod 301
It moves in _five directions.

On the outer periphery of the base plate 80, a position detection switch 52 is arranged. Position detection switch 5
2 stores a solenoid for unlocking the shift lock, a printed wiring board, and the like. The position detection switch 52 has a holder 55, a moving contact 56, a first fixed contact 57, and a second fixed contact 58, as shown in FIG. The holder 55 includes the switch drive rod 301 and the connection hole 30.
5 and a switch drive rod 3
Works in conjunction with 01 movement.

Next, the operation of the fifth embodiment will be described. As shown in (b) of FIG. 40, when the shift lever 85 is shifted to the P range, the roller 313 presses the first cam surface 303 having an inclined surface, so that the switch drive rod 301 moves to the arrow X _4. Move in the direction
Holder 55 of the position detecting switch 52 is moved to a predetermined position F _1. In this state, since the moving contact 56 comes into contact with the first fixed contact 57, the shift of the shift lever 85 to the P range is detected by the position detection switch 52.

When the shift lever 85 is shifted to the D range, the shift lever 85 passes through the P 'range. However, when the shift lever 85 is in the P' range, the shift lever 85 is shifted to the position shown in FIG. since the roller 313 as shown away from the first cam surface 303, the switch drive rod 301 returns to the neutral position F _0. The fact that the shift lever 85 is in the P 'range cannot be ascertained by the position detection switch 52, but this can be ascertained by the automatic transmission linked to the shift lever 85. When the shift lever 85 is shifted to the D range, as shown in FIG.
Since 3 moves away from the second cam surface 304, the switch drive rod 301 remains returned to the neutral position (a). Also in this case, the fact that the shift lever 85 is in the D range cannot be grasped by the position detection switch 52, but can be grasped on the automatic transmission side similarly to the P 'range.

When the shift lever 85 is shifted to three ranges as shown in FIG.
There therefore presses the second cam surface 304, the switch drive rod 301 moves in the arrow X ₅ direction, the holder 55 of the position detecting switch 52 is moved to a predetermined position F _2. In this state, since the moving contact 56 comes into contact with the second fixed contact 58, the shift of the shift lever 85 to the three ranges is detected by the position detection switch 52.

In the fifth embodiment, since the respective cam surfaces 303 and 304 are pressed by the rollers 313, the frictional resistance on the cam surfaces can be reduced, and the operation force when moving the switch drive rod 301 is reduced. However, it is possible to simply use the cam surface 3 without using the roller 313.
A configuration in which the user presses 03 and 304 may be used. Further, a roller may be provided on the switch drive rod 310 side. In this embodiment, since the fixed contacts 57 and 58 are provided on the same position detection switch 52, only one position detection switch 52 is required. Further, since the position detection switch 52 is provided on the outer peripheral portion of the base plate 80, there is no need to lower the position of the detent portion 80a.
The detent portion 80a for positioning the shift lever 85 in each range can be arranged at a position advantageous in strength.

【The invention's effect】

(1) According to the shift lever device for an automatic transmission of the first to third aspects, when the shift lever is located in the P range, the moving contact that moves by the movement of the holder contacts the first fixed contact. When the shift lever is located in a specific range other than the P range, the moving contact that moves by the movement of the holder is brought into contact with the second fixed contact, so that only one position detection switch is required. The number of position detection switches can be reduced. (2) According to the shift lever device for an automatic transmission according to claims 1 to 3, the position detection switch is mounted on the outer peripheral portion of the upper base or the base plate, so that the position detection switch is positioned in each range of the shift lever as compared with the conventional device. It is not necessary to lower the position of the detent part to be formed. This allows
It is possible to ensure a large length from the pivot point of the shift lever to the detent portion. Therefore, the force acting on the detent portion when positioning the shift lever in each range can be suppressed to a small value, and the detent portion can have a structure advantageous in strength.
