2. Description of the Related Art In a vehicle assembly line, there is a case where only a front wheel and a rear wheel on one side of a vehicle are placed on a conveyor, and the front wheel and a rear wheel on the other side are rolled on a floor to move the vehicle. In this case, if the shift lever for the automatic transmission of the vehicle is shifted to the P range (parking range),
It is necessary to shift the shift lever to the N range (neutral range) because the rotation of the wheels is locked and the vehicle may come off the assembly line.

In a shift lever device, the shift lever is P
There is a case where a key lock mechanism that allows the ignition key to be removed from the key cylinder only when the range is shifted to the range is connected. In the vehicle assembly line, there is a process to inspect the trunk and back door of the vehicle using the key removed from the key cylinder.

SUMMARY OF THE INVENTION
The shift lever device disclosed in JP-A-51271 has the following problem. In the shift lever device of this publication, the temporary holding member is assembled in a state where the shift lever is shifted to the N range on the assembly line. When the key is removed from the key cylinder and another inspection is performed, the release member is moved in the forward direction of the vehicle, and then the temporary holding member is rotated clockwise, so that much work is required. In addition, since this operation requires a complicated operation, erroneous operations often occur. In addition to the above publications, there is an apparatus of a system in which the emergency shift lock release button must be pressed when returning the shift lever to the use state, and the restraint of the shift lock plate is released in the same manner as described above. Operation becomes complicated. 2. Description of the Related Art In vehicles, a shift lock mechanism is provided to prevent the shift lever from erroneously starting at the time of starting.
The shift lock of the shift lever is performed by a swingable lock plate, and the movement of the shift lock plate is transmitted to the key lock mechanism via a cable. Therefore, in order to perform the inspection using the key while moving the vehicle by the conveyor, it is necessary to restrict the position of the shift lock plate to the position where the key comes out,
After the inspection, it is necessary to easily release the constraint of the shift lock plate.

According to the present invention, at the time of assembling the vehicle, the shift lock plate in a state where the shift lever is shifted to the N range is restrained in the same posture as the state where the shift lever is shifted to the P range, and It is an object of the present invention to provide a shift lever device for an automatic transmission capable of releasing the restraint of a shift lock plate by a simple operation after assembly is completed.

[0006]

A shift lever device for an automatic transmission according to the present invention which achieves this object is as follows. (1) a shift lever pivotally supported by the base plate; a detent pin provided on the shift lever, which is disengaged from the detent plate by being depressed by pressing a shift button, and pivoting toward the base plate. A shift lock plate that is provided so as to be able to prevent the detent pin from being pushed down, and prevents the shift lock plate from swinging downward by engagement with the shift lock plate; An actuator for releasing the engagement, a lock mechanism connected to the shift lock plate via a cable, a set pin movably set on the base plate and abuttable on the shift lock plate, and formed on the base plate. , For positioning of the set pin A first regulating portion for preventing the swinging of the shift lock plate Ri, second to allow swinging of the shift lock plate by the positioning of the set pin
A restricting hole having a restricting portion, and a set pin provided in the shift lever and abutting with a set pin positioned by the first restricting portion of the restricting hole by a shift operation of the shift lever from the N range to the P range, A cam flange for moving the set pin from the first restricting portion to the second restricting portion;
A shift lever device for an automatic transmission, comprising: (2) a shift lever swingably supported by the base plate, a detent pin provided on the shift lever, which is disengaged from the detent plate by being depressed by pressing a shift button, and swingable by the base plate. A stopper for preventing the detent pin from being pushed down by contact with the detent pin; and an actuator connected to the stopper and releasing the contact between the detent pin and the stopper located in the P range by depressing a brake pedal. A shift lock plate which is swingably held by the base plate and is pushed back to a predetermined tilt angle in a direction opposite to a biasing direction by contact with a detent pin located in a P range, and is connected to the shift lock plate via a cable. Locking mechanism and front It provided the shift lock plate, first held in the first tilt angle near the shift lock plate to the predetermined tilt angle by the contact between the stopper 1
Holding means, provided on the shift lock plate,
A second holding means for holding the shift lock plate at a second tilt angle by contacting the stopper when the shift lever is shifted to a range other than the P range. Shift lever device for transmission.

In the shift lever device for an automatic transmission (1), the shift lever is shifted to the N range when the vehicle is assembled. When the shift lever is shifted to the N range, the wheels of the vehicle are rotatable, so that the vehicle can be moved while only one side of the wheels is placed on the conveyor of the assembly line. When the shift lever is shifted to the N range at the time of assembling the vehicle, the set pin positioned in the first restricting portion of the restricting hole abuts on the shift lock plate. Cannot be depressed, and the shift lock plate is restrained in the same posture as the state where the shift lever is in the P range. As a result, the lock mechanism connected to the shift lock plate via the cable has the same function as the state in which the shift lever is shifted to the P range, and the lock mechanism is, for example, a key lock mechanism. In some cases, it is possible to remove the key from the key cylinder. Therefore, the vehicle can be inspected using the key removed from the key cylinder without locking the wheels of the vehicle on the assembly line. After the vehicle assembling work by the conveyor is completed, the shift lever is shifted from N range to P
Returned to range. In this case, the set pin positioned at the first restricting portion moves to the second restricting portion by the cam flange provided on the shift lever. Since the set pin positioned in the second regulating portion allows the shift lock plate to swing, the shift lock plate can be pushed down by pressing the shift button. When the shift lever is shifted from the P range to the N range in a state where the set pin is positioned at the second regulating portion, the lock mechanism is driven via the cable by the swing of the shift lock plate, and the key cylinder is moved from the key cylinder to the key. Can not be overtaken. In the automatic transmission shift lever device (2), the shift lever is shifted to the N range when the vehicle is assembled. When the shift lever is shifted to the N range, the wheels of the vehicle are rotatable, so that the vehicle can be moved while only one side of the wheels is placed on the conveyor of the assembly line. When the shift lever is shifted to the N range at the time of assembling the vehicle, the stopper comes into contact with the first holding means of the shift lock plate, so that the shift lock plate is held at the first tilt angle. In this state, the shift lock plate is restrained in almost the same posture as the state in which the shift lever is in the P range. As a result, the lock mechanism connected to the shift lock plate via the cable has the same function as the state in which the shift lever is shifted to the P range, and the lock mechanism is, for example, a key lock mechanism. In this case, the key can be removed from the key cylinder. Therefore, without locking the wheels of the vehicle on the assembly line,
Inspection of the vehicle using the key removed from the key cylinder becomes possible. After the vehicle assembling operation by the conveyor is completed, the shift lever is returned from the N range to the P range.
When the shift lever is returned to the P range, the shift lock plate is pushed back to a predetermined tilt angle in a direction opposite to the biasing direction by contact with the detent pin. Since the predetermined tilt angle is close to the first tilt angle, even after the shift lever is shifted to the P range, the shift lock plate is held in substantially the same attitude as the first tilt angle, and the key is released from the key cylinder. It can be pulled out. When shifting the shift lever to a range other than the P range, the actuator operates by depressing the bouquet pedal, and the stopper swings in a predetermined direction. As a result, the stopper comes into contact with the second holding means of the shift lock plate, and the shift lock plate changes from the predetermined tilt angle to the second tilt angle. Therefore, the lock mechanism connected to the shift lock plate via the cable is driven, and the key cannot be removed from the key cylinder.

The cam flange 85 comes into contact with the set pin 76 positioned by the first restricting portion 72 of the restricting hole 70 by the shift operation of the shift lever 11 from the N range to the P range, and moves the set pin 76 to the first restricting portion 72. To the second regulating portion 73. The set pin 76 positioned at the second restricting portion 73 is constantly pressed against the peripheral edge of the end of the second restricting portion 73 by the spring 81. The set pin 76 moved to the second restricting portion 73 by the cam flange 85 remains positioned at the second restricting portion 73 unless it is manually extracted from the restricting hole 70.

Next, the operation of the first embodiment when assembled in a vehicle will be described. FIG. 1 shows a state in which the shift lever device 5 is incorporated into the vehicle 1. The shift lever device 5 is supplied to an assembly line of the vehicle with the shift lever 11 shifted to the N range. FIG. 4 shows a normal assembled state of the shift lever device 5, but FIG.
In the case of (1), the cam is not in a proper assembling state due to the assembling procedure, and the cam portion 26 of the shift lock plate 20 to be in contact with the guide pin 16 is not in contact with the guide pin 16.
When the shift lever device 5 is supplied to the assembly line of the vehicle, the set pin 76 is already positioned at the first restricting portion 72 of the restricting hole 70. The setting of the set pin 76 of the shift lever device 5 supplied to the assembly line to the first restricting portion 72 is performed in the following procedure. First, the set pin 76 is inserted into the insertion portion 71 of the restriction hole 70 of the base plate 10, and then the set pin 76 is inserted into the restriction hole 70.
Then, the set pin 76 is pressed against the end of the first restricting portion 72 by the spring 81.

As shown in FIG. 1, the shift lever 11
When the vehicle is shifted to the range, the wheels 2 of the vehicle 1 are rotatable, so that the vehicle 1 can move with only the front and rear wheels 2 on one side placed on the conveyor 3. In a state where the set pin 76 is positioned at the first regulating portion 72,
The set pin 76 is provided on the lower surface 27 of the shift lock plate 20.
Abut. Since the first restricting portion 72 extends obliquely upward, even if the shift lock plate 20 is pressed down, the set pin 76 is moved to the edge 72 a of the first restricting portion 72.
, The shift lock plate 20 cannot swing downward.

When the set pin 76 positioned by the first restricting portion 72 is in contact with the lower surface 27 of the shift lock plate 20, the shift lock plate 20 is in the same posture as when the shift lever 11 is shifted to the P range. Is kept. Therefore, the engagement between the terminal fitting 45 serving as a lock mechanism (key lock mechanism) connected to the shift lock plate 20 via the cable 40 and the key cylinder cam 49 is released, and the shift lever 11 is shifted to the N range. Even if the key cylinder 46 is shifted from the key cylinder 46
Can be omitted. Therefore, the other parts of the vehicle 1 can be inspected using the key 44.

When the assembly work of the vehicle 1 by the conveyor 3 is completed, the shift lever 11 is shifted from the N range to the P range as shown in FIG. In this case, the detent pin 14 abuts on the link member 30, but since the link member 30 can swing in the direction of arrow B, the swing of the link member 30 can shift the shift lever 11 to the P range. it can. When the shift lever 11 shifts to the N range, the set pin 76 is pushed down by the cam flange 85, and the set pin 76 is moved from the first restricting portion 72 to the second restricting portion 73 by the urging force of the spring 81. Moving. The set pin 76 is in the second regulating portion 7
In the state where the shift lock plate 20 is positioned, the set pin 76 is located below the lower swing limit of the shift lock plate 20, so that the shift lock plate 20 can swing downward. As shown in FIG. 3, after the shift lever 11 is shifted to the P range, the set pin 76 positioned by the second restricting portion 73 is left without being removed.

Next, the operation of the shift lever device 5 during vehicle operation in the first embodiment will be described. When the shift lever 11 is shifted to the P range, the detent pin 14 is urged upward by the urging force of a spring (not shown) housed in the shift lever 11, so that the detent pin 14 Detent plate 1
5 is engaged with the notch 15a. When the shift lever 11 is in the P range, the engagement surface 25 of the shift lock plate 20 and the plunger 51 of the solenoid 50 are moved.
Can be engaged, even if the shift button 13 is pressed to depress the detent pin 14 without depressing a brake pedal (not shown), the shift lock plate 20 does not swing downward. Therefore, the detent pin 14 is still engaged with the notch 15a of the detent plate 15, and the shift operation of the shift lever 11 from the P range to another range becomes impossible.

When a brake pedal (not shown) is depressed by a predetermined amount or more, the energization of the solenoid 50 causes the plunger 51 to move away from the engagement surface 25 of the shift lock plate 20, and the shift lock plate 20 and the plunger The engagement with 51 is released. Here, when the detent pin 14 is pressed down by pressing the shift button 13, the shift lock plate 20 swings downward due to the pressing of the detent pin 14. Accordingly, the engagement between the detent pin 14 and the notch 15a of the detent plate 15 is released, and as shown in FIG.
1 can be shifted to a range other than the P range.

When the shift lever 11 is shifted to a range other than the P range, the shift lock plate 20 swings downward due to the contact between the guide pin 16 and the cam portion 26, so that the shift lock plate 20 is connected via the cable 40. Terminal fitting 4
5 also moves, and the terminal fitting 45 engages with the key cylinder cam 49 of the key cylinder 46. Therefore, the key 44
Since the key 44 cannot be turned to the CK position, the key 44 is prevented from coming off the key cylinder 46. Shift lock plate 2
0, the top surface of the cam portion 26 coincides with the movement locus of the guide pin 16, so that even if the shift lever 11 is shifted to each range other than the P range, the shift lock plate 20
Is kept constant. Therefore, the terminal fitting 45
Remains engaged with the key cylinder cam 49 in the rotational direction, and the key 44 cannot be removed from the key cylinder 46.

In the state shown in FIG. 3, when the solenoid 50 stops operating due to a voltage drop of the battery or the like, the cylinder lock is released by the lock release button 62. When the top of the lock release button 62 is pressed, the lower end of the lock release button 62 abuts on one top surface 32b of the link member 30, and the link member 30 rotates in the direction opposite to the biasing direction by the torsion spring. Therefore, the link member 30
Is no longer located directly below the detent pin 14, and it is possible to avoid contact between the detent pin 14 and the regulating surface 32a. Therefore, the detent pin 14 can be pushed down below the notch 15a of the detent plate 15, and the shift lever 11 can be shifted from the P range to another range.

In the second embodiment, a shift lock plate 90 is mounted on the base plate 10 as shown in FIGS. Shift lock plate 9
Numeral 0 enables swinging in the front-rear direction of the vehicle around the shaft portion 90a. The shift lock plate 90 has a V-shape in plan view. The cable 40 is connected to one side of the shift lock plate 90. The other end 90b of the shift lock plate 90 projects in the horizontal direction.
The other end 90b can contact the detent pin 14. The shift lock plate 90 is urged in the direction of arrow A by a torsion spring 91 as urging means disposed on the outer periphery of the shaft portion 90a. The shift lock plate 90 is provided with a first holding means 92 and a second holding means 94. The first holding means 92 and the second holding means
Of the positioning hole 96 formed in the shift lock plate 90 is formed by a part of the inner peripheral surface. A direction). The biasing force of the torsion spring 91 is set to be larger than the value obtained by adding the sliding resistance (frictional force) of the cable 40 and the load on the key side.

The base plate 10 has a stopper 100
Is installed. The stopper 100 is disposed diagonally below the shift lock plate 90 and has a shaft portion 100.
It can swing in the front-rear direction of the vehicle around a. The stopper 100 has a substantially Y-shaped planar shape. One side of the stopper 100 extends substantially upward, and the regulating surface 100b located at the top can contact the detent pin 14. The other side of the stopper 100 extends toward the positioning hole 92 of the shift lock plate 90. A boss 101 is formed at the other end of the stopper 100. The boss 101 has entered the positioning hole 96 and can contact either the first holding means 92 or the second holding means 94. The lower end 100 c of the stopper 100 is connected to the plunger 51 of the solenoid 50. The stopper 100 swings due to the reciprocation of the plunger 51 of the solenoid 50. The stopper 100 is urged in the direction of arrow A by the spring 52 of the solenoid 50. A cushion 102 having an elastic body such as rubber is provided on an outer peripheral portion of the stopper 100 between the shaft portion 100a and the boss 101. The cushion 102 has entered a substantially square stopper hole 98 formed in the base plate 10. The cushion 102 can come into contact with the inner peripheral surface of the stopper hole 98, and restricts excessive movement of the stopper 100. The top on the other side of the stopper 100 is formed on a pressing surface 103 to which the lock release button 62 can abut.

Next, the operation of the second embodiment when incorporated into a vehicle will be described. FIG. 10 shows a state in which the shift lever device 5 is assembled into a vehicle. The shift lever device 5 is supplied to the vehicle assembly line with the shift lever 11 shifted to the N range. FIG.
This is for creating a so-called pseudo state in which the attitude of the shift lock plate 90 is set to the same attitude as the shift lever 11 has been shifted to the P range, instead of the normal operation state. As shown in FIG. 10, when the shift lever 11 is shifted to the N range, the vehicle 1
Wheel 2 is rotatable, so that the vehicle 1 can move with only the front and rear wheels 2 on one side placed on the conveyor. In FIG. 10, since the boss 101 of the stopper 100 contacts the first holding means 92, the shift lock plate 90
Is held at the first tilt angle θ ₁ , and the cable 40 is pushed into the key lock mechanism. Therefore, the engagement between the terminal fitting 45 and the key cylinder cam 49 is released, and the key 44 can be removed from the key cylinder 46 even when the shift lever 11 is shifted to the N range. Therefore, the inspection of the trunk, the back door and the like of the vehicle 1 using the key 44 becomes possible.

In the first embodiment, a simulated state of the P range is created by the set pin 76 which is not related to the shift lock mechanism. In this embodiment, however, the shift lock plate 90 which is an essential component of the shift lock mechanism is provided. Stopper 100
, A positioning hole 92 and a boss 101 are respectively formed,
Since the pseudo state of the P range is created, no new parts are required. Therefore, compared to the first embodiment in which the set pin 76 is left as it is, no parts are wasted, and the cost can be reduced.

When the assembling of the vehicle by the conveyor is completed, the shift lever 11 is shifted from the N range to the P range. When the shift lever 11 is shifted from the N range to the P range, the detent pin 14 comes into contact with the stopper 100, so that the stopper 100 swings in the direction of arrow B as shown in FIG. The plate 15 is now ready to enter the notch 15a. Since the detent pin 14 is biased upward by the biasing force of a spring (not shown) housed in the shift lever 11, when the shift lever 11 is shifted to the P range, the detent pin 14 Notch 15
and enters the state of FIG. . In the state of FIG. 11, the lower surface of the other end portion 90 b of the shift lock plate 90 swings in the direction of arrow B by the urging force of the detent pin 14. Here, since the upward movement of the detent pin 14 is restricted to a predetermined value, the tilt angle θ ₃ of the shift lock plate 90 is substantially equal to the first tilt angle θ _{1 in} the state of FIG.
It becomes something close to. Therefore, also in this case, it is possible to extract the key 44 from the key cylinder 46.

Next, the operation of the shift lever device 5 during the operation of the vehicle in the second embodiment will be described. FIG.
As shown in FIG. 5, when the shift lever 11 is shifted to the P range, the detent pin 14 is urged upward by the urging force of a spring (not shown) housed in the shift lever 11. , Detent pin 14
Are engaged with the notches 15a of the detent plate 15. In the state where the shift lever 11 is in the P range, even if the shift button 13 is pressed to push down the detent pin 14 without depressing a brake pedal (not shown), as shown in FIG. Pin 1
4 is in contact with the regulating surface 100b of the stopper 100,
The detent pin 14 cannot be pushed down more than a predetermined amount. Therefore, the detent pin 14 is still engaged with the notch 15a of the detent plate 15,
The shift operation of the shift lever 11 from the P range to another range becomes impossible.

When a brake pedal (not shown) is depressed by a predetermined amount or more, the stopper 100 swings in the direction of arrow B by energizing the solenoid 50, and the engagement between the detent pin 14 and the notch 15a of the detent plate 15 is established. And the shift lever 11 can be shifted to a range other than the P range as shown in FIG. When shifting the shift lever 11 to a range other than the P range, the stopper 100 is turned on by energizing the solenoid 50.
Swings in the direction of arrow B, and the boss 101
4, the shift lock plate 90 is held at the _second tilt angle θ2. Therefore, the terminal fitting 45 connected to the shift lock plate 90 via the cable 40 also swings according to the _second tilt angle θ ₂ , and the terminal fitting 45
Engages with a key cylinder cam 49 of the key cylinder 46. Therefore, the key 44 cannot be turned to the LOCK position, and the key 44 is prevented from falling out of the key cylinder 46.

After the shift lever 11 is shifted to a range other than the P range, the energization of the solenoid 50 is stopped, but the stopper 100 is provided by the boss 101 of the first holding means 92 and the second holding means 94. Since the boss 101 does not swing in the direction of arrow A because it is in contact with the step between the bosses, the boss 101 remains in contact with the second holding means 94. Therefore, when the shift lever 11 is shifted to each range other than the P range, the shift lock plate 90 is maintained at the second tilt angle θ ₂ , so that the terminal fitting 45 is rotated with the key cylinder cam 49 in the rotation direction. And the key cylinder 4
The key 44 cannot be removed from 6.

If the solenoid 50 stops operating due to a drop in battery voltage or the like in the state of FIG. 11, the cylinder lock is released by the lock release button 62. As shown by the two-dot chain line in FIG. 13, when the lock release button 62 is pressed, the lock release button 62 comes into contact with the pressing surface 103 of the stopper 100, and the stopper 100 swings in the direction of arrow B. Therefore, the regulating surface 100b is no longer located immediately below the detent pin 14, and it is possible to avoid contact between the detent pin 14 and the regulating surface 100b. Therefore, the detent pin 14 is connected to the detent plate 1
5 can be pushed down below the notch 15a,
The shift lever 11 can be shifted from the P range to another range.

FIGS. 15 and 16 show a modification of the second embodiment. In FIG. 11, the shift lock plate 9
The shift lock plate 9 using the positioning holes 96
Although the swing angle of 0 is restricted, as shown in FIGS. 15 and 16, a first holding means 112 and a second holding means 114 are provided near the upper end of the outer peripheral portion of the shift lock plate 90. A configuration in which a flange 116 projecting in the horizontal direction may be provided. The first holding means 112 and the second holding means 114 are constituted by a part of the lower surface of the flange 116, and the first holding means 112 is provided with the second holding means 114.
Projecting more in the swinging direction. A boss 120 protruding upward is provided near the upper end of the stopper 100.

FIG. 15 shows a state where the shift lever 11 is in the P range. In this case, detent pin 1
4 can be brought into contact with the regulating surface 100b of the stopper 100, so that the shift operation to another range cannot be performed. FIG.
Shows a state in which the shift lever 11 is shifted to a range other than the P range. In this case, since the boss 120 abuts on the second holding means 114, the shift lock plate 90 is held at the second tilt angle. When the shift lever device 5 is delivered to the assembly line, the boss 120 and the first
The shift lock plate 90 is held at the first tilt angle by the contact with the holding means 112, thereby creating a pseudo state in which the shift lock plate 90 is maintained in the same posture as the shift lever 11 shifted to the P range.

In the above embodiment, the case where the lock mechanism is applied to the key lock mechanism has been described. However, the lock mechanism is not limited to the key lock mechanism, and may be applied to, for example, a steering lock mechanism. Is also possible.
