Abstract

PROBLEM TO BE SOLVED: To simply restore a pseudo-key interlock release condition even when the pseudo-key interlock velease condition is turned into a normal condition. SOLUTION: A rope part 140 having its leading end extended to the crew side through a shift hole 26 in a housing 24, is formed from a shift lock plate 80. When a shift lever 22 is turned to an N-position after a pseudo-key interlock release condition is turned into a normal condition, by pulling the rope part 140 in this condition, the shift block plate 80 is slide upward while a plunger 74 in a shift lock solenoid 66 is pulled out by an urging force of a compression coil spring 78, and accordingly, a stopper 76 is shifted to a portion where the downward slide of the shift lock plate 80 can be limited. Thereby, it is possible to simply restore the pseudo-key interlock release condition.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever device for changing a shift range of a transmission of a vehicle.

[0002]

2. Description of the Related Art In a vehicle manufacturing process, a vehicle that has undergone a mounting process of a shift lever device for operating an automatic transmission has a shift range of the automatic transmission set to a neutral range (hereinafter referred to as "N range"). The vehicle is transported to the next process by one-wheel transport in which the wheels are freely rotatable and only one wheel in the vehicle width direction is grounded on the floor and the wheels are rolled and transported while rolling. is there.

In a vehicle manufacturing process, there is a step of checking whether an ignition key matches a key cylinder of a door or a trunk. In this step, it is necessary to remove the ignition key from a key cylinder of a driver's seat. is there. However, usually, the shift lever device is provided with a key interlock mechanism, and the shift lever is moved to a P position corresponding to a parking range (hereinafter, referred to as a “P range”) of the automatic transmission to shift the shift lever of the vehicle. Unless the drive wheels are locked, the key cannot be removed from the key cylinder in the driver's seat. Therefore, if the automatic transmission is changed to the P range by shifting the shift lever to the P position for the above-described inspection, one-wheel conveyance becomes impossible, and the production efficiency (inspection efficiency) is reduced. For this reason, even if the shift lever is located at the N position corresponding to the N range (that is, even when the drive wheels are rotatable), a mechanism that allows the ignition key to be extracted from the key cylinder (hereinafter, such a mechanism is described). Such a mechanism is referred to as a “pseudo key interlock release mechanism”) provided in the shift lever device.

[0004]

In such a pseudo key interlock release mechanism, a lock member such as a shift lock plate or a key interlock plate is moved to a P position by fitting an elastically deformed claw or the like. Hold in the same state as the position, after the above inspection,
The shift lever is once shifted to the P position and then shifted to the N position again to release the fitting state of the above-mentioned claw or the like, and to release the pseudo key interlock release state. is there. Further, after the pseudo key interlock release state is released, the lock member cannot be held by the above-mentioned claw or the like so that the pseudo key interlock release state is not inadvertently set.

[0005] As described above, the pseudo key interlock release mechanism can be easily released only by operating the shift lever. Therefore, if the shift lever is operated before the above-described inspection process is completed, a basic operation is required. In practice, the pseudo key interlock cannot be released again. Therefore, in this case, it is necessary to temporarily disassemble the components such as the housing and return to the pseudo key interlock release state, so that a mechanism capable of easily releasing the pseudo key interlock release state when needed is desired.

The present invention has been made in consideration of the above-described circumstances, and has as its object to provide a shift lever device that can easily restore the pseudo key interlock release state even when the pseudo key interlock release state returns to the normal state.

[0007]

According to a first aspect of the present invention, there is provided a shift lever device, wherein one end of the shift lever device is rotatably supported by a turning shaft provided on a side opposite to the vehicle compartment via a housing provided in the vehicle compartment. The other side is connected to the transmission of the vehicle on the side opposite to the vehicle interior, and the other end is extended to the vehicle interior side through the housing and set to the transmission by a turning operation around the turning axis. A shift lever that changes a shift range, and a turning position corresponding to a parking range that locks a drive wheel of the vehicle out of a shift range set in the transmission, on a side opposite to the vehicle interior through the housing. A shift position that is provided at a lock position where rotation of the shift lever from the lock position to another rotation position can be restricted, and that can be moved from the lock position to an unlock position where the restriction is released. Lock member and the shift lock member are urged toward the movement locus of the shift lock member from the lock position to the unlock position, and move the shift lock member to the unlock position at the restricted position on the movement locus. In addition to the restriction, the restriction is released by releasing from the restriction position against the urging force by a predetermined restriction release operation, and the shift to the restriction position is restricted by the shift lock member in the unlock position. Connected to the shift lock member and extended through the housing to the outside of the housing, and transmits the external force to the shift lock plate by application of an external force from the outside of the housing. Operating means for moving the shift lock member at the lock release position to the lock position.

According to the shift lever device having the above-described configuration, in a state where the movement of the shift lock member is restricted by the restricting means at the restricted position, the movement of the shift lock member to the unlocked position is restricted by the restricting means. Therefore, of the shift range set for the transmission, the shift lever is shifted from a turning position (hereinafter, this turning position is referred to as a “P position” for convenience) corresponding to the parking range for locking the driving wheels of the vehicle to another turning position. When the user attempts to turn the shift lever, turning of the shift lever from the "P position" to another turning position is restricted by the restricting means via the shift lock member. For this reason, in this state, the shift range of the transmission cannot be changed from the parking range to another shift range.

When a predetermined restriction releasing operation (for example, a depression operation of a brake pedal provided on the vehicle) is performed from this state, the restricting means separates from the restricted position against the urging force, and the shift is performed. The lock member can be moved to the unlock position. Therefore, in this state, although the shift lock member is in the lock position, if the shift lever is turned, the shift lock member is moved to the unlock position. Therefore, the shift lever is moved from the "P position" to another turning position. The transmission can be turned, and the shift range of the transmission can be changed from the parking range to another shift range.

Further, while the shift lever is turned to another turning position, an external force is applied to the operating means (for example,
When the shift lock member is moved from the unlock position to the lock position, the restricting means is displaced to the restrict position by the urging force, and the movement of the shift lock member from the lock position to the unlock position is restricted. Is limited by That is, in this state, the shift lever is set to “P
Position, the shift lock member and the restricting means are in substantially the same state as when the shift lever is at the "P position".

Therefore, the shift lever pivots to the "P position", whereby the operation which can be performed only when the shift lock member or the restricting means is at the position released from the unlock position or the restricted position is shifted to the "P position". This can be done even when the lever is not turning.

According to a second aspect of the present invention, there is provided the shift lever device according to the first aspect, wherein the operating means and the shift lock member are connected to each other by a predetermined disconnection operation. It is characterized by comprising a connecting means capable of releasing the connection with the connecting means.

In the shift lever device having the above structure, when a predetermined disconnection operation is performed on the operation means, the connection between the operation means and the shift lock member by the connection means is released, and the operation means is moved toward the vehicle interior. If pulled, the operating means is pulled out into the vehicle compartment and removed. Therefore, in this state, the shift operation of the shift lock member from the lock release position to the lock position via the operation means cannot be performed. This prevents inadvertent operation of the shift lock member after the operation means is pulled out.

The connecting means in the present invention is not limited to a structure for mechanically connecting the operating means and the shift lock member, but also includes a predetermined operation such as pulling, shearing, twisting, etc., with respect to the operating means. The stress is concentrated and destroyed,
A stress-concentrated portion that releases the connection between the operating means and the shift lock member, or a weakness configured to easily concentrate such stress by setting a mechanical strength lower than that of the shift lock member of the operating means in advance. Including parts.

A through hole 30 is formed in the cover slide 28, and the upper end side of the shift lever 22 penetrates through the through hole 30 and the shift hole 26 and protrudes toward the occupant's living space in the vehicle cabin.

As shown in FIG. 1, the shift lever 22
A knob 32 for gripping is attached to the upper end of the.
A button 34 is slidably attached to the knob 32 substantially toward the left side of the vehicle. As shown in FIG. 7, a pin 36 is attached to the substantially left end portion of the button 34 on the vehicle.
Is formed so as to protrude, and abuts on a cam portion 39 provided at an upper end portion of a rod 38 disposed inside the shift lever 22 so as to be slidable along the longitudinal direction of the shift lever 22. This rod 38 is a compression coil spring 40
By pressing the button 34, the rod 38 slides downward against the urging force of the compression coil spring 40.

A detent pin 42 projects from a part of the outer periphery of the rod 38 substantially toward the left side of the vehicle. The detent pin 44 extends coaxially with the detent pin 42 substantially toward the right side of the vehicle. Are formed to protrude. These detent pins 42 and 44 project outside the shift lever 22 through a pair of slit holes 46 formed in the shift lever 22 along the longitudinal direction of the shift lever 22.

Further, as shown in FIG. 1, a locking plate 50 to which one end of a wire 48 is locked is fixed from a part of the outer periphery of the shift lever 22. The other end of the wire 48 is directly or indirectly connected to an automatic transmission 52 of the vehicle as a transmission via a connecting member such as a link.
By pulling or releasing the locking plate 50, the shift range of a plurality of stages set in the automatic transmission 52 can be changed. Here, the plurality of characters 54 formed on the upper bottom surface of the housing 24 along the shift hole 26 are:
Each of the shift ranges set in the automatic transmission 52 is shown, and the shift lever 22 is turned around the shaft 20 to pull or release the pulling of the wire 48 and shift to any side of the plurality of characters 54. By moving the lever 22 to the position (ie, shift position), the shift range can be changed to the shift range corresponding to the character 54 on the side. In addition, among the plurality of characters 54, the character 54 of "P"
2 means a parking range in which the driving wheels of the vehicle are locked. The letter "R" 54 indicates a reverse range of the automatic transmission 52, in which the drive wheels of the vehicle are reversed and the vehicle moves backward. further,
The letter 54 of "N" means a neutral range of the automatic transmission 52, in which the drive wheels of the vehicle can rotate freely (hereinafter, the lateral shift position of the letter 54 of "P" is " The lateral shift position of the character 54 of "P position" and "R" is referred to as "R position", and the lateral shift position of the character 54 of "N" is referred to as "N position".

One end of a leaf spring 51 is screwed to the locking plate 50. This leaf spring 51 corresponds to a moderation plate 53 erected on the base plate 12, and when the shift lever 22 is turned to the side of any of the characters 54, the other spring is generated by the spring force of the leaf spring 51 itself. Moderation plate 53 at the end
Into any one of the plurality of moderation grooves 60 formed in the groove. As a result, the shift lever 22 is turned with moderation.

On the other hand, as shown in FIG. 1, a bottomed detent hole 56 is opened in the vertical wall 14 of the base plate 12 substantially toward the right side of the vehicle.
6, the tip of the detent pin 42 enters.
As described above, the rod 38 is connected to the compression coil spring 4.
0, the detent pin 42 integral with the rod 38 normally comes into contact with the upper inner peripheral portion 58 of the detent hole 56, and the shift lever 22 is When the swivel operation is performed around the detent pin 42 along the upper inner peripheral portion 58,
Moves.

A part of the upper inner peripheral portion 58 is a restricting portion 62 protruding downward, and the detent pin 42 must be moved to the lower end side of the shift lever 22 to a position where the restricting portion 62 can be avoided. In other words, no further turning operation (shift operation) of the shift lever 22 can be performed unless the button 38 is pressed to slide the rod 38 downward.

On the other hand, a shift lock solenoid 66 as a restricting means is disposed substantially on the right side of the shift lever 12 in the vehicle direction. This shift lock solenoid 6
Reference numeral 6 includes a solenoid body 68 in which a coil and a core (not shown) are housed. A lead wire 70 electrically connected to an internal coil is drawn out of the solenoid body 68, and the coil is connected to the shift lock computer 72 via the lead wire 70. For example, when a brake switch (not shown) detects that a brake pedal (not shown) of the vehicle is depressed, the shift lock computer 72 energizes the coil of the solenoid body 68 via the lead wire 70. To excite the core.

The solenoid body 68 is provided with a plunger 74 which is elongated substantially in the longitudinal direction of the vehicle. The plunger 74 is formed of a magnetic material such as metal. When the core of the solenoid body 68 is excited, the plunger 74 slides substantially toward the front of the vehicle by the magnetic force and is drawn into the solenoid body 68. Further, the solenoid body 6
8 is a compression coil spring 7 near the rear end of the vehicle.
8, which urges the plunger 74 in a direction of being pulled out from the solenoid body 68. Further, a stopper 76 as a restricting means is provided at the tip end of the plunger 74.
Is mounted, and slides along the plunger 74 substantially in the vehicle front-rear direction.

A plate-like shift lock plate 80 as a shift lock member is provided above the stopper 76 when the plunger 74 is pulled out from the solenoid body 68. The shift lock plate 80 is slidable substantially along the vertical direction of the vehicle along a guide projection 81 formed on the guide plate 79, but the stopper 76 is located below the shift lock plate 80 (ie, in the claims). When the shift lock plate 80 is positioned at the limit position, the downward slide of the shift lock plate 80 is limited by the stopper 76, and the plunger 74 is pulled into the solenoid main body 68, and the stopper 7 is stopped.
6 is displaced (that is, the shift lock plate 8
The shift lock plate 80 can slide downward by its own weight when the vehicle departs from the restricted position on the movement locus of zero.

The shift lock plate 80 is formed with a cutout portion 84 which penetrates in the thickness direction and opens at an end of the shift lock plate 80 substantially on the rear side of the vehicle. The notch 84 is slightly larger than the outer diameter of the detent pin 44 described above.
On the substantially vehicle left side of the shift lock plate 80, a portion substantially forward of the restricting portion 62 of the detent hole 56 described above, that is, when the shift lever 22 is shifted to the "P position", a detent pin is provided. When the shift lever 22 is shifted to the "P position" and the detent pin 42 moves substantially forward of the vehicle, bypassing the restricting portion 62, the detent pin 44 is notched. It goes into the part 84. A cam portion 85 is formed at an end of the shift lock plate 80 substantially on the rear side of the vehicle and below the open end of the notch 84.
The cam portion 85 is an inclined surface which is directed substantially rearward of the vehicle and substantially upward of the vehicle. By applying a pressing force from the rear side to the cam portion 85, the shift lock plate 80 itself is moved downward. Can be done.

As shown in FIG. 2, the shift lock plate 80 is restricted from sliding downward by the stopper 76 (that is, the shift from the lock position is restricted in the claims). Status)
Then, the notch portion 84 extends substantially along the vehicle front-rear direction.
Opposes. Therefore, if the detent pin 44 enters the notch 84 in this state, the detent pin 44 cannot avoid the restricting portion 62 and presses the inner wall of the notch 84 to shift the shift lock plate 80. Cannot be slid downward to move to a position where the restriction portion 62 can be avoided. Therefore, in this state, the shift lever 22 cannot be shifted from the "P position" to the "R position" (that is, the shift lock plate 80 locks the shift lever 22 at the "P position").

Further, as shown in FIG. 1, an engagement portion 86 extends from the shift lock plate 80 substantially toward the right side of the vehicle. The engaging portion 86 is formed with an elongated hole 88 that opens substantially toward the right side of the vehicle. A box-shaped switch body 9 that is opened substantially toward the left side of the vehicle is provided on the substantially right side of the vehicle.
A switch box 98 is provided which includes a switch body 4 and a lid 96 for closing an opening end of the switch body 94 substantially on the left side of the vehicle. As shown in FIG. 8, a slider 100 is provided in the switch body 94 of the switch box 98.
Are slidably accommodated in the up-down direction. The slider 100 has a protrusion 102 protrudingly formed on the substantially right side of the vehicle, the protrusion 102 being engageable with the elongated hole 88 of the above-described engaging portion 86. The protrusion 102 extends through an opening 104 formed in the lid 96. The hole 88 is engaged. Therefore, this slider 1
00 slides up and down in conjunction with the vertical sliding of the shift lock plate 80.

On the other hand, a sliding contact 110 which is elongated substantially in the longitudinal direction of the vehicle is fixed to an end of the slider 100 substantially on the right side of the vehicle. Fixed contacts 112 and 114 each having a length substantially along the vertical direction of the vehicle are provided on the inner bottom of the 94.

When the shift lock plate 80 is slid to the upper side of the vehicle, the sliding contacts 110 are fixed to the fixed contacts 112 and the fixed contacts 1 at both ends in the longitudinal direction.
14 and fixed contact 112 and fixed contact 114
When the restriction of the downward slide of the shift lock plate 80 by the stopper 76 is released and the shift lock plate 80 is slid downward, the sliding contact 1
10 are spaced apart from the fixed contacts 112,114.

The fixed contacts 112 and 114 are electrically connected to the shift lock computer 72 shown in FIG. 1 through connection means such as lead wires. 1
It is determined whether or not the shift lever 22 has been shifted to the “P position” from the conduction state of 14.

The shift lock computer 72 is shown in FIG.
Are electrically connected to a key interlock solenoid 120 of a key cylinder 118 shown in FIG. As shown in FIG. 9, the key interlock solenoid 120 includes a coil 122 electrically connected to the shift lock computer 72, and a plunger 124 is provided inside the coil 122 along the axial direction of the coil 122. It is slidably housed. Further, the plunger 12
A core 126 is coaxially housed inside the coil 122 on one side in the axial direction of the coil 4. When the coil 122 is energized to excite the core 126, the plunger 124 is attracted to the core 126. Configuration. A lock pin 128 is fixed to an end of the plunger 124 on the core 126 side. The tip of the lock pin 128 penetrates the core 126, and when the plunger 124 is sucked by the core 126 and slides, the key cylinder 1
18.

A compression coil spring 130 is provided on the side of the plunger 124 opposite to the core 126, and urges the plunger 124 toward the compression coil spring 132. On the other hand, a compression coil spring 132 is provided around the lock pin 128, and urges the lock pin 128 in a direction away from the core 126 via a flange portion 134 formed on the lock pin 128. The flange portion 134 is larger than the urging force of the compression coil spring 132. Therefore, when the core 126 is not excited, the lock pin 128 is held at a position where the lock pin 128 does not protrude into the key cylinder 118. However, when the core 126 is excited and the core 126 attracts the plunger 124,
The resultant force of the suction force of the core 126 and the urging force of the compression coil spring 132 exceeds the urging force of the flange portion 134, and the lock pin 128 projects into the key cylinder 118.

On the other hand, a cam 138 that rotates together with an ignition key 136 inserted in the key cylinder 118 is accommodated in the key cylinder 118. When the ignition key 136 is rotated from the ACC position to the LOCK position, the ignition key 136 can be removed. However, when the lock pin 128 is inserted into the key cylinder 118, the lock pin 128
38, the rotation of the cam 138 is restricted, so that the ignition key 136 cannot be rotated. Therefore, the ignition key 136 cannot be removed.

As shown in FIGS. 1 and 2, from the upper end of the above-described shift lock plate 80, a long cord 140 as operating means extends. The string portion 140 is formed of the same material as the material forming the shift lock plate 80 (for example, when the shift lock plate 80 is formed of a synthetic resin material, the same material is used). The tip is cover slide 2.
8 through the through hole 30 and the shift hole 26 of the base plate 12, and is drawn out to the occupant side of the vehicle cabin.

Here, the strength of the thin portion 142 with respect to the pulling in the longitudinal direction is such that it can sufficiently withstand the pulling force of pulling up the shift lock plate 80 in a state of sliding downward.

Further, as shown in FIG. 2, the base end of the string portion 140 (ie, the shift lock plate 80)
Is a thinner portion 142 which is thinner than other portions of the cord portion 140 as a connecting means. This thin portion 142 is set to have a smaller cross-sectional area than other portions of the string portion 140, and therefore, when the string portion 140 is pulled,
The tensile stress concentrates on the thin portion 142. Therefore,
The thin portion 142 is a part of the string portion 1 more than other portions of the string portion 140.
Although the strength of the shift lock plate 80 in the longitudinal direction is low, the shift lock plate 80 in the state of sliding downward has enough strength to withstand the pulling force of pulling it upward.

Next, the operation and effect of this embodiment will be described.

As shown in FIG. 2, the shift lever device 10 is sent to the vehicle assembling process in a state where the shift lever 22 has been shifted to the "P position". (For example, a floor portion between a driver's seat and a passenger seat of a vehicle).

After the shift lever device 10 has been assembled,
Only one of the left and right wheels (tires) of the vehicle is placed on a conveyor such as a conveyor or a lift and transported. At this time, since the other wheel is in contact with the ground, it is necessary to be in a state in which it can freely roll at the time of transportation and the automatic transmission 52 is changed to the neutral range. However, since the ignition key 136 (refer to FIG. 9) passes through a process of checking whether or not the ignition key 136 matches a key cylinder of a vehicle door or a key cylinder of a luggage door (not shown), the ignition key 136 is set to the key cylinder 118. Must be able to be extracted from

Therefore, when assembling the shift lever device 10, the shift lever 22 is shifted to the "N position" to change the automatic transmission 52 to the neutral range as shown in FIG. 80
Slide up. When the shift lock plate 80 is slid upward, the plunger 74 is pulled out of the solenoid main body 68 by the urging force of the compression coil spring 78, whereby the stopper 76 restricts the slide lock plate 80 from sliding downward. When the shift lock plate 80 slides upward, the fixed contact 112 and the fixed contact 114 are electrically connected via the sliding contact 110. When the shift lock computer 72 determines that the fixed contact 112 and the fixed contact 114 are in a conductive state, the shift lock computer 72 releases the energization of the coil 122 of the key interlock solenoid 120. As a result, the attractive force of the coil 122 that has been acting up to that point is released, so that the compression coil spring 130
The lock pin 128 comes out of the key cylinder 118 due to the difference between the urging force of the compression coil spring 132 and the urging force of the compression coil spring 132. Accordingly, in this state, the rotation restriction of the cam 138 by the lock pin 128 is released, and the key cylinder 11
8 lock the ignition key 136
The ignition key 136 can be removed from the key cylinder 118 by rotating to the position (pseudo key interlock released state).

As a result, the key cylinder 11 is moved in a state where the shift range of the automatic transmission 52 is set to the neutral range.
By pulling out the ignition key 136 from 8, it is possible to confirm whether the ignition key 136 matches a key cylinder of a vehicle door or a key cylinder of a luggage door (not shown).

By the way, usually, the shift lever 22 is set to "P
Shift position from position to any other shift position (for example, "N position")
When the shift operation is performed, first, a predetermined release operation such as depressing a brake pedal of the vehicle is performed, and a coil in the solenoid main body 68 is energized to excite the internal core, thereby moving the plunger 74 into the solenoid main body 68. The restriction on downward sliding of the shift lock plate 80 by the retraction stopper 76 is released. Next, the detent pin 44 is displaced downward together with the shift lock plate 80 by pressing the button 34 of the knob 32 (the state shown in FIG. 4). Thereby, the detent pin 44 can avoid the restriction portion 62, and in this state, by turning the shift lever 22 substantially toward the rear side of the vehicle, the shift lever 22 can be moved to another shift position (FIG. 5 state). Here, in this state, the shift lock plate 80 slides downward even when the energization of the coil of the solenoid main body 68 is released, whereby the fixed contact 112 and the fixed contact 1
14 is released, the lock pin 128 is released.
Protrudes into the key cylinder 118 to limit the rotation of the cam 138. Therefore, in this state, the ignition key 136 cannot be removed from the key cylinder 118 (key interlock state).

On the other hand, even when the shift lever device 10 is in the pseudo key interlock release state, when the shift lever 22 is shifted to the "P position", the detent pin 44, which has bypassed the restricting portion 62, has the cam portion of the notch 84. 85, the shift lock plate 80 is slightly pushed down to enter the notch 84, and the normal key interlock is released. In this state, the brake pedal is depressed and the button 34 of the knob 32 is pressed to operate the shift lever. When the shift operation of the button 22 is performed, a key interlock state is set. Therefore, it is basically impossible to return to the pseudo key interlock release state by the ordinary turning operation of the shift lever 22.

However, in the present shift lever device 10, the shift lever 22 is moved to the "N position" by a normal shift operation.
When the cord 140 is pulled through the through hole 30 of the cover slide 28 and the shift hole 26 of the housing 24 and pulled out to the occupant side of the vehicle, the tension at this time is applied to the shift lock plate 80. Then, the shift lock plate 80 slides upward.
At this time, if the release operation of the brake pedal or the like has not been performed, the plunger 74 is pulled out of the solenoid body 68 by the urging force of the compression coil spring 78, and the stopper 76 restricts the shift lock plate 80 from sliding downward. As a result, the shift lever device 10 enters the pseudo key interlock release state again.

Therefore, after the shift lever device 10 is assembled to the vehicle, the shift lever 22 is operated to shift from the pseudo key interlock release state of the shift lever device 10 to the key interlock state or the normal key interlock release state. Even if the state, the housing 24
It is possible to easily return to the pseudo key interlock release state without disassembling the components of the shift lever device 10 such as the above.

The thin portion 14 is provided at the base end of the string portion 140.
As shown in FIG. 6, when the string portion 140 is pulled with a force greater than the pulling force when the shift lock plate 80 is slid upward, the thin portion 142 is broken. Therefore, after the end of the inspection process or the like, there is no need to intentionally create the pseudo key interlock release state, and then the string portion 140 is pulled with a force greater than the pulling force when the shift lock plate 80 is slid upward. When the portion 142 is broken, the connection between the string portion 140 and the shift lock plate 80 is released, and when the string portion 140 is pulled as it is, the base end of the string portion 140 becomes the through hole 30 of the cover slide 28 and the shift hole of the housing 24. 26, the entire cord portion 140 is pulled out to the occupant side in the vehicle interior.

In other words, in this state, the means for re-creating the pseudo key interlock release state has been substantially removed from the shift lever device 10, so that the shift lever device 10 is inadvertently moved. There is no lock release state.

Further, in the present shift lever device 10, the structure other than the cord portion 140 including the thin portion 142 is basically the same as the conventional shift lever device. The string portion 140 is also formed on the shift lock plate 80, and is merely drawn through the through hole 30 of the cover slide 28 and the shift hole 26 of the housing 24 to the occupant side in the vehicle cabin. Therefore, basically, the above-described effects can be obtained without increasing the number of parts.

Further, in the present shift lever device 10, the structure other than the string portion 140 including the thin portion 142 is basically the same as the conventional shift lever device. Here, in the conventional shift lever device, many components are required for the structure for releasing the pseudo key interlock, but in the present shift lever device 10, special components for releasing the pseudo key interlock are used. The shift lever 22 is not provided with a mechanism for creating a normal key interlock state and a key interlock release state.
, The pseudo lock interlock release state is created by forcibly sliding the shift lock plate 80 upward even though it is at the "N position". For this reason, in the present shift lever device 10, parts required for creating the pseudo key interlock release state can be basically completely eliminated, and there is an additional effect that the cost can be greatly reduced.

In this embodiment, the key cylinder 1 of the ignition key 136 is turned on and off by energizing and de-energizing the coil 122 of the key interlock solenoid 120.
A so-called electric key interlock mechanism that controls the rotation of the shift lock plate 80 is constructed by mechanically connecting a cam 138 to a predetermined part of the base plate 12 via a cable or the like. The cable is pulled or released in conjunction with the key cylinder 1 of the ignition key 136.
A so-called mechanical key interlock mechanism for controlling the rotation of 18 may be configured.

Further, the shift lever device according to the present embodiment has a structure including the cord portion 140 as operating means, but the operating means is mechanically connected to the shift lock plate 80 and at least the shift of the housing 24 is performed. The configuration is not limited as long as it is drawn out from the hole 26 or the like to the occupant side in the vehicle interior and can be pulled from the occupant side in the vehicle interior. Therefore, for example, the operation means may be sheet-shaped.

Further, in the present embodiment, the thin portion 142 having a smaller cross-sectional area than other portions of the string portion 140 is used as the connecting means, and the string portion 140 is pulled to concentrate stress on the thin portion 142 and break it. Configuration. However,
Even if the connecting means has a structure in which the stress is concentrated and broken, the structure of the connecting means is similar to that of the thin-walled portion 140.
The configuration is not limited to a configuration in which the cross-sectional area is smaller than that of the other portions. That is, for example, the site to be broken (ie,
Heat-treating the part 140 as a connecting means)
If the mechanical strength is lowered by reducing the density of the material forming the shift lock plate 80 only at the portion where the density is broken, stress concentrates by pulling the string 140 similarly to the thin portion 142. Since the thin portion 142 is formed at the bent portion, the same effect as when the thin portion 142 is formed can be obtained.

Next, a second embodiment of the present invention will be described. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

FIG. 10 is a perspective view showing a main part of a shift lever device 150 according to a second embodiment of the present invention. As shown in this figure, the shift lever device 150 includes a shift lock plate 152 corresponding to the shift lock plate 80 of the shift lever device 10 according to the first embodiment. The shift lock plate 152 has basically the same configuration as the shift lock plate 80, but the string portion 140 formed on the shift lock plate 80 is
52 is not formed.

On the upper side of the notch 84 of the shift lock plate 152, a through hole 154 is formed as a connecting means penetrating in the thickness direction of the shift lock plate 152. A string-like member 156 as a flexible, small-diameter or thin-walled operation means such as a wire or a hemp string is engaged with the through-hole 154 through the through-hole 154. The string-like member 156 is folded at a portion penetrating the through-hole 154, and both ends in the longitudinal direction pass through the through-hole 30 of the shift hole 26 and the shift hole 26 of the housing 24 (see FIG. 1) similarly to the string portion 140. And it is drawn out to the occupant side in the vehicle interior. Further, both ends in the longitudinal direction of the string-shaped member 156 are twisted with each other to be substantially integrated.

In the present shift lever device 150, the shift lock plate 80 can be slid upward by pulling both ends of the string-like member 156 in the longitudinal direction. The same operation as the lever device 10 is exerted, and the same effect can be obtained.

On the other hand, in the first embodiment, the thin portion 142 is broken by pulling the string portion 140 with a force sufficiently larger than the pulling force when the shift lock plate 80 is slid upward. 140 is removed to prevent the pseudo key interlock release state from being carelessly returned to the pseudo key interlock release state after the pseudo key interlock release state becomes unnecessary. On the other hand, in the case where the pseudo key interlock release state is unnecessary in the present embodiment, first, the both ends in the longitudinal direction of the twisted string member 156 are unwound and one end in the longitudinal direction is removed. And the other end. In this state, if one of the longitudinal ends of the cord-like member 156 is pulled (in this case, the tensile force may be of any magnitude), either of the other ends is shifted by the shift hole 26 of the housing 24 and the cover. The through hole 30 of the slide 28 is drawn into the rear side of the housing 24, further passes through the through hole 154 of the shift lock plate 152, and again passes through the through hole 30 of the cover slide 28 and the shift hole 26 of the housing 24. To the occupant side in the vehicle compartment. Thereby, the engagement state between the string-like member 156 and the shift lock plate 152 is released, and the means for re-creating the pseudo key interlock release state has been substantially removed from the shift lever device 150. The shift lever device 150 does not inadvertently enter the pseudo key interlock release state (in other words, by twisting both ends of the string-shaped member 156 in the longitudinal direction, the shift lever plate 150 can Disengagement with the cord-like member 156 can be prevented).

As described above, in the present embodiment, the through holes 154 are formed in the shift lock plate 152 and the through holes 154 are formed.
, And only the longitudinal ends of the through-hole 154 are drawn out toward the occupant in the vehicle cabin. Therefore, the same effect as in the first embodiment can be obtained at low cost.

In this embodiment, the string-like member 156 is used.
Are twisted at both ends in the longitudinal direction to prevent inadvertent release of the engagement between the shift lock plate 152 and the string-shaped member 156. However, the twisting of both ends in the longitudinal direction of the string-shaped member 156 is performed. The alignment is not an essential requirement of the present invention, and therefore, both ends in the longitudinal direction of the cord-like member 156 need not be substantially integrated.

In the present embodiment, the longitudinal ends of the cord-like member 156 are simply twisted to be substantially integrated. For example, the both ends in the longitudinal direction of the string-shaped member 156 are connected and fixed to the portion of the shift lever device 150 exposed to the occupant side in the vehicle compartment and other portions exposed to the occupant side in the vehicle compartment. May be. Even in this case, careless shift lock plate 152 and string-like member 1
56 can be released.
