Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door lock device.

[0002]

2. Description of the Related Art In a conventional door lock device, a latch disposed on a vehicle door and capable of engaging with and disengaging a striker on the vehicle body side, and a pawl capable of restricting the operation of the latch by abutting the latch, A lift lever that can operate the pole from the contact state with the latch to the non-contact state, an open link that operates by operating a door handle or the like arranged on the vehicle door, and a lock knob or the like arranged on the vehicle door. A known technique includes a lock lever that moves the set position of the open link by operation.

In such a device, the open link reciprocates in a fixed direction (reciprocal movement between the unlock initial position and the lock initial position) by the operation of the lock lever. Here, when the open link is located on the unlock initial position side, the door lock device is in the unlocked state, and when it is located on the lock initial position side, the door lock device is in the locked state. In the unlocked state, the open link can be moved from the unlock initial position to the unlock full stroke position by operating the door handle or the like. In the locked state, the open link can be moved from the locked initial position to the locked full stroke position by operating the door handle or the like. The lift lever is arranged so as to be offset from the movement trajectory between the lock initial position and the lock full stroke position of the open link. That is, in the locked state, the open link does not engage with the lift lever, and the latch does not come out of engagement with the striker when the door handle or the like is operated.

It is known that these devices have the following problems when the door handle and the lock knob are operated in a superposed manner in a locked state. That is, when the door handle is operated slightly earlier, the open link moves from the lock initial position to the lock full stroke position, and then tries to move from the lock full stroke position to the unlock full stroke position direction. . At this time, a state in which the open link cannot move to the unlock full stroke position may occur due to the engagement of the open link with the lift lever. Therefore, when the operation of the door handle is subsequently returned to the original state, the switching to the unlocked state remains unestablished (this state is referred to as a panic state), even though the lock knob has been operated once. Therefore, in order to switch to the unlocked state, it is necessary to operate the lock knob again, which is a troublesome operation. In addition, such a problem also occurs in a door lock system that automatically switches from a locked state to an unlocked state by detecting that a person approaches the door handle to operate the door handle. It can happen as well. This is because, depending on the control timing, the manual door handle operation may occur earlier than the automatic switching operation to the unlocked state.

As a device for solving the above-mentioned problems, a device disclosed in Japanese Patent Laid-Open No. 11-166337 is known. The structure is shown in FIG. This device includes a lift lever 90 that operates a pawl from a contact state with a latch to a non-abutment state, and an open lever 91 that operates by operating a door handle or the like arranged on a vehicle door.
And the open link 9 linked to the open lever 91
2 and a lock lever 93 that is operated by a lock knob or the like arranged on the vehicle door to move the set position of the open link 92, and the open link 92 connects the open lever 91 and the lock lever 93 to the main link 92a. And is supported by a pin 95 relative to the main link 92a so as to be rotatable relative to the main link 92a,
And a sub-link 92b engageable with.

In this device, when the door handle or the like and the lock knob or the like are operated in a superposed manner in the locked state, they operate as follows. First, open link 92
Moves to the lock full stroke position and then to the unlock full stroke position in the direction. At this time, the sub-link 92b engages with the lift lever 90, but the sub-link 92b rotates relative to the main link 92a, so that the main link 92a can move to the unlock full stroke position. There is. After that, when the door handle is returned to its original position, the spring 94 causes the sub link 92b to rotate relative to the main link 92a, whereby the entire open link 92 returns to the unlock initial position (from the panic state. To return). Therefore, it is not necessary to operate the lock knob again.

However, in this device, the following problems may occur due to its structure. When the door is opened in the unlocked state, the torque generated by operating the door handle causes the open lever 91 and the main link 92a to operate.
Be transmitted to. The main link 92a moves the sub link 92b in the substantially longitudinal direction (lower left direction in FIG. 9), and the tip end portion 92c of the sub link 92b presses the lift lever 90. Here, the main lever 92a and the sub-lever 92b are rotatably connected by the pin 95 as described above. Therefore, when the sub link 92b presses the lift lever 90, the sub link 92b is not stably supported by the main link 92a. That is, there is a possibility that the sub link 92b and the main link 92a rotate relative to each other and the lift lever 90 cannot be accurately pressed.
Although the relative rotation between the sub link 92b and the main link 92a is regulated by the spring 94, when the relative relationship between the urging force of the spring 94 and the operation required torque of the lift lever 90 changes, the above There is a possibility that a malfunction may occur, and the operation of the door lock device becomes unstable.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to suppress the troublesome operation of a door lock device without causing instability in the operation.

[0009]

Means for Solving the Problems To solve the above-mentioned problems, a technical means taken by the present invention is a latch arranged on a vehicle door and detachable from a striker on the vehicle body side. A pawl capable of restricting the operation of the latch by contacting with the latch, a lift lever capable of operating the pawl from a contact state with the latch to a non-contact state, and a door opening provided in the vehicle door A link member that is operated by operating a member, and an unlocking position that is operated by operating a locking / unlocking member provided on the vehicle door, and that is capable of engaging the lift lever when the link member is operated; A door lock device comprising: a lock lever that moves between the lift lever and a lock position where the lift lever cannot be engaged; a main lever in which the lift lever is linked to the pawl. Yobi該 is the main lever and relatively movable arranged a said link member engageable with the sub-lever, is that where the structure comprises a resilient member between said main lever sub-lever.

According to this structure, for example, even when the link member engages with the lift lever when switching from the locked state to the unlocked state, the sub-lever moves relative to the main lever, so that the link member moves. be able to. That is, regardless of the main lever, the link member can move together with the sub lever (the link member and the sub lever are integrated). Therefore, switching from the locked state to the unlocked state can be established. That is, with these configurations, in the locked state, even if the door opening member and the locking / unlocking member are operated in a superimposed manner, the panic state does not occur and the switching to the unlocked state can be established. Therefore, it is not necessary to operate the locking / unlocking member again, and the troublesome operation can be suppressed. When the link member is disengaged from the lift lever, the elastic member causes the sub-lever to move relative to the main lever (return operation). In addition, this configuration does not divide the link member that engages with the lift lever. Therefore, the operation of operating the lift lever by the link member in the unlocked state becomes stable.

Preferably, when the link member is operated by operating the door opening member, the link member is engageable with the sub lever in one direction, and the link member is moved by operating the locking / unlocking member. In this case, the link member is engageable with the sub lever in the other direction, is formed on at least one of the main lever or the sub lever, and restricts relative movement of the sub lever in the one direction with the main lever. , A first guide portion for guiding relative movement of the sub-lever in the other direction with respect to the main lever may be provided.

In this structure, when the link member is engaged with the sub lever by the operation of the door opening member, the sub lever and the main lever are integrally operated in one direction by the first guide member. That is, there is no loss of torque transmitted from the sub-lever to the main lever, and the torque is stably transmitted from the door opening member to the pole. When the link member is engaged with the sub-lever by operating the locking / unlocking member, the first
Since the guide member guides the relative movement of the sub-lever in the other direction with respect to the main lever, the movement is stable.

Another technical measure taken in the present invention to solve the above-mentioned problems is a latch disposed on a vehicle door and detachable from a striker on the vehicle body side, and the latch. A pawl capable of restricting the operation of the latch by abutting, a lift lever operable to move the pawl from a contact state with the latch to a non-contact state, and a door opening member disposed on the vehicle door. A link member that is operated by an operation and an unlocking member that is operated by an operation of a locking / unlocking member provided on the vehicle door, and that is capable of engaging the link member with the lift lever when the link member is operated, and the lift. A lock lever that moves between a lever and a lock position where engagement is not possible, wherein the lift lever is operated by operating the door opening member of the link member. An abutment portion that comes into contact with the link member when actuated in one direction, and an avoidance portion that avoids abutment with the link member when the link member is moved in the other direction by operation of the locking / unlocking member. That is the structure.

According to this structure, for example, when the lock member is switched from the locked state to the unlocked state by operating the locking / unlocking member, even if the link member moves in the other direction, the contact between the link member and the lift lever is avoided. Avoided by the department. Therefore, the link member can move regardless of the lift lever, and the switching from the locked state to the unlocked state can be established. That is, with these configurations, in the locked state, even if the door opening member and the locking / unlocking member are operated in a superimposed manner, the panic state does not occur and the switching to the unlocked state can be established. Therefore, it is not necessary to operate the locking / unlocking member again, and the troublesome operation can be suppressed. In addition, this configuration does not divide the link member that engages with the lift lever. When the link member is operated in one direction by operating the door opening member, the contact portion causes the link member and the lift lever to contact each other. Therefore, torque transmission in one direction from the link member to the lift lever becomes stable.

Preferably, the abutting portion is a first plane portion which is substantially perpendicular to the one direction, and the avoiding portion is a second plane portion which is inclined with respect to the other direction.

With this configuration, the above-mentioned problems can be easily solved by setting the relative angles of the one plane and the first plane section and the other direction and the second plane section.

[0017] Preferably, the lift lever is a flexible arm portion extending from the base portion in the other direction and having the first flat surface portion and the second flat surface portion at the tip thereof. A second guide portion for restricting the bending of the arm portion in the one direction may be provided.

With this structure, the range of movement of the second plane portion with respect to the link member is increased by bending the arm portion, and contact between the second plane portion and the link member is more reliably avoided. Become.

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) The first embodiment will be described with reference to FIGS. First, the latch mechanism portion of the door lock device 10 (door lock device) will be described with reference to FIG. The door lock device 10 is arranged on a door (not shown) (vehicle door), and includes a latch 11 (latch) and a pole 12 (pole). Further, the latch 11 has a housing groove 11a.
The housing groove 11a engages with and holds the striker 13 (strike) attached to the vehicle body (not shown). Further, the pole 12 has a contact portion 12a. The contact portion 12a contacts the latch 11 and restricts the rotation of the latch 11. The latch 11 and the pole 12 are pivotally supported on the shaft 14 and the shaft 15 of the door lock device 10 so as to be integrally rotatable.

The operation of the latch mechanism of the door lock device 10 will be described below. In FIG. 1, the latch 11 is the striker 1.
3 shows a latch state in which 3 is held. In this latched state, the door is held closed with respect to the vehicle body. In the unlatched state in which the latch 11 is rotated clockwise by a predetermined angle from the latched state in FIG. 1, the storage groove 11a of the latch 11 coincides with the cutout portion 16 formed in the door, so that the striker 13 moves in the left direction in FIG. You can leave.
Therefore, the door is ready to open with respect to the vehicle body. The latch 11 is biased in the clockwise direction in FIG. 1 by a spring 17 arranged around the shaft 14. That is, the rotation of the latch 11 is due to the urging force of the spring 17. Here, as described above, the pole 12 restrains the rotation of the latch 11 by the contact portion 12a in the latched state. However, when the pole 12 rotates clockwise by a predetermined angle in FIG. 1, the contact portion 12a and the latch 11 are rotated.
Is released, and the latch 11 rotates to the unlatched state. That is, the pawl 12 operates the latch 11 by changing the contact state to the non-contact state with respect to the latch 11. The pole 12 is also biased in the counterclockwise direction in FIG. 1 by a spring 18 arranged around the shaft 15.

Next, the portion of the lock mechanism of the door lock device 10 will be described with reference to FIGS. As shown in FIG. 2, the door lock device 10 has a configuration in which an open lever 21, a link 22 (link member), a lift lever 23 (lift lever), and a locking lever 24 (locking lever) are arranged on a base 20. Has become.

The open lever 21 is pivotally supported with respect to the base 20 by a pin 29 located substantially at the center in the longitudinal direction. The open lever 21 is biased in the clockwise direction shown in FIG. 2 by a spring (not shown). Further, the open lever 21 has an engaging end portion 21a formed at the right end in FIG. Engaging end 21
"a" is configured to be operated by operating an inside door handle (not shown) (door opening member) arranged on the vehicle interior side of the door via another lever (not shown) or the like. That is, the open lever 21 is rotated about the pin 29 by a predetermined amount in the counterclockwise direction in FIG. 2 by operating the inside door handle.

The open lever 21 has a connecting end 21b and a locking claw 21c formed on the opposite side of the engaging end 21a with the pin 29 in between. A rod 30 linked to an outside door handle (not shown) (door opening means) arranged outside the vehicle of the door is connected to the connecting end 21b. Therefore, even when the outside door handle is operated, the open lever 21 rotates about the pin 29 in the counterclockwise direction in FIG. The locking claw portion 21c is bent and extends from the open lever 21 in the front direction of the paper surface of FIG. The locking claw 21c has a link 22
The link 22 and the open lever 21 are connected to each other.

The link 22 has a connecting hole 22a and an engaging portion 2
2b and a long hole 22c are formed. The connection hole 22a is a substantially 8-shaped hole formed at one end (upper end in FIG. 2) of the link 22, and the locking claw portion 21c is locked. Also,
An elongated hole 22c extending along the longitudinal direction of the link 22 is formed at the other end (lower end in FIG. 2) of the link 22.
An engaging portion 22b extending obliquely downward to the right in FIG. 2 is formed from substantially the center in the longitudinal direction of the link 22. Also,
The engaging portion 22b is located near the lift lever 23.

The lift lever 23 is a main lever 40.
(Main lever), sub-lever 41 (sub-lever), spring 42 (spring), and bush 43. As shown in detail in FIG. 3, in the lift lever 23, the connecting portion 15a of the shaft 15 is integrally inserted into the elongated connecting hole 40a formed in the main lever 40 and the elongated hole 41a formed in the sub lever 41. , And the bush 43 is fixed. The main lever 40 and the shaft 15 are connected to each other by the shapes of the connecting hole 40a and the connecting portion 15a.
The structure is such that they rotate integrally around the shaft 15. Further, the main lever 40 is formed with two inclined flanges 40b (first guide portion).
The sub-lever 41 is fitted between the individual inclined flanges 40b. The engagement between the inclined flange 40b and the sub-lever 41 restricts the sub-lever 41 from rotating relative to the main lever 40 about the shaft 15. With the above configuration, when the turning torque is applied to the engaging flange 41b of the sub lever 41 in the X direction (one direction) in the drawing, the sub lever 41, the main lever 40, the shaft 15, and eventually the pole 12 are integrally formed. Rotate. At this time, the pawl 12 rotates clockwise in FIG. 1, and as a result, the latch 11 is switched from the latched state to the unlatched state.

Further, since the inclined flange 40b is formed along the Y direction (other direction) in the drawing, the sub lever 4
1 guides relative movement in the Y direction with respect to the main lever 40. It should be noted that the connecting portion 15a of the shaft 15 is configured to move within the elongated hole 41a when this relative movement is performed. A spring 42 is provided on the arm 41c of the sub-lever 41. One end 42a of the spring 42
Is engaged with the connecting portion 15a, and the other end 42b is connected to the sub lever 4
It engages with the restraining flange 41c formed in 1. The sub-lever 41 is biased by the spring 42 against the main lever 40 in the direction opposite to the Y direction shown in FIG.

The locking lever 24 has its longitudinal direction substantially in the left-right direction in FIG. 2, and is rotatably supported by the base 20 via a pin 28 at substantially the center of the longitudinal direction. In the vicinity of the pin 28 of the locking lever 24, as shown in FIG.
A connecting shaft 24a extending in the front direction of the paper surface is formed. By inserting the connecting shaft 24a into the long hole 22c of the link 22, the locking lever 24 is moved to the link 22.
Connected with. In addition, the locking lever 24 is shown in FIG.
A connection elongated hole 24b is formed at the left end shown in the drawing, and connection holes 24c and 24d are formed at the right end shown in FIG. The connection elongated hole 24b is connected via a rod 25 or the like to a key cylinder (not shown) (locking / unlocking member) arranged on the vehicle outer side of the door. The connecting hole 24c is connected via a rod 26 or the like to a lock knob (not shown) (locking / unlocking member) arranged on the vehicle compartment side of the door. An output arm 27 of a locking actuator (not shown) (locking / unlocking member) is inserted through the connecting hole 24d.
The locking actuator is installed in the vehicle by a lock / unlock switch (not shown) signal, a keyless entry switch (not shown) signal provided on the key, or the outside door handle. It operates by a signal from a human detection system (called a smart key entry system) including a capacitance sensor (not shown). With the above configuration, the locking lever 24 is rotatable about the pin 28 with respect to the base 20 by operating a locking actuator or the like.

The operation of the door lock device 10 will be described below with reference to FIGS. 2 and 4 to 8.

First, the operation of opening the door with the outside door handle will be described. Figure 2
The unlocked state of the door lock device 10 is shown. The unlocked state is a state in which the door can be opened (the latch 11 can be switched from the latched state to the unlocked state) by operating the outside door handle or the like. The position of the link 22 with respect to the base 20 in this state is the unlock initial position (unlock position). When the outside door handle is operated in this state, the link 22 is moved to the position shown in FIG.
Moves downwards. As a result, as shown in FIG. 4, the engaging portion 22b of the link 22 engages with the engaging flange 41b of the sub-lever 41, and the engaging flange 41b extends substantially downward in FIG.
push. This direction substantially coincides with the X direction at the position of the engaging flange 41b. This state is shown in FIG. That is, by operating the outside door handle or the like, the link 22 moves from the unlock initial position to the position shown in FIG. 4 (unlock full stroke position), and this movement causes the entire lift lever 23 to center on the shaft 15. And Figure 4
It operates counterclockwise. As a result, as described above, the door is switched to the unlatched state and the door can be opened.

Next, the operation of switching the door lock device 10 between the unlocked state and the locked state by the locking actuator will be described. What is a locked state?
Depending on the operation of the outside door handle or the like, the door cannot be opened (the latch 11 cannot be switched from the latched state to the unlatched state).

In the unlocked state shown in FIG. 2, when the locking lever 24 is rotated about the pin 28 in the clockwise direction in FIG. The link 22 is interlocked via the hole 22c. That is, the link 22 is rotated about the connecting hole 22a in the counterclockwise direction in FIG. 2 by a predetermined angle. As a result, as shown in FIG. 5, the link 22 has its engaging portion 22b with the sub-lever 4
The first engaging flange 41b moves to a position where it cannot be engaged. The position of the link 22 shown in FIG. 5 with respect to the base 20 is referred to as a lock initial position (lock position). This state is the locked state of the door lock device 10. FIG. 6 shows a state in which the link 22 is moved substantially downward in FIG. 5 by operating the outside door handle in this locked state.
That is, the link 22 moves from the initial lock position to the full lock stroke position shown in FIG. However,
The movement locus of the engaging portion 22b when moving from the lock initial position to the lock full stroke position is as follows.
It is offset from b. Therefore, due to such an operation, the entire lift lever 23 does not operate, and the latch 11 does not switch from the latched state to the unlatched state.

The locking lever 2 is operated by operating a locking actuator or the like from the locked state shown in FIG.
When 4 rotates in the counterclockwise direction shown in FIG. 5, the link 22 moves to the unlock initial position and enters the unlocked state shown in FIG.

Next, the operation when the locking actuator or the like is operated in the state shown in FIG. 6 will be described. When the locking lever 24 is rotated counterclockwise in FIG. 6 about the pin 28 by the operation of the locking actuator, the link 22 moves in the unlock full stroke position. As a result, as shown in FIG. 7, the engaging portion 22b engages with the engaging flange 41b.
Then, by further operation of the locking actuator or the like, the sub-lever 41 moves relative to the main lever 40 in the Y direction shown in FIG. This relative movement resists the biasing force of the spring 42. As a result, the link 22 moves in the direction of the unlock full stroke position with the pulling of the sub-lever 41, and the state shown in FIG. 8 is obtained. In this state, when the operation of the outside door handle is returned to the original state, the link 22 moves substantially upward in FIG. Then, the engaging portion 22b and the engaging flange 41b
When the engagement is released, the door lock device 10 enters the unlocked state shown in FIG. At this time, the urging force of the spring 42 causes the sub-lever 41 to move relative to the main lever 40 in the direction opposite to the Y direction in FIG.

As described above, in the locked state,
Even when the operation of the outside door handle or the like and the operation of the locking actuator or the like are superimposed, when the operation of the outside door handle or the like is returned to the original state, it is switched to the unlocked state. Therefore, it is not necessary to perform the switching operation to the unlocked state again, and the troublesome operation is suppressed. In addition, in the present embodiment, the link 22 is not divided in order to achieve this purpose (reduction of troublesome operation). Therefore, during the normal door opening operation, the link 22 moves the lift lever 2
3 The operation to operate the whole is stable. That is, in the present embodiment, the sub-lever 41 is moved by the inclined flange 40b during the normal door opening operation.
The main lever 40 is integrally rotated. Therefore, there is no loss of torque transmitted from the sub-lever 41 to the main lever 40, and the entire torque transmission from the outside door handle to the pole 12 is stably performed. In this embodiment, the inclined flange 40
Although b is formed on the main lever 40, a portion having the same function may be formed on the sub lever 41 or both.

(Second Embodiment) Next, FIG. 9 to FIG.
A second embodiment will be described based on 2. Compared to the first embodiment, the present embodiment has the same configuration except the lift lever 23, and thus the description thereof will be omitted.

As shown in FIG. 10, the lift lever 23 is
It is composed of a main lever 50 and a sub-lever 51. The main lever 50 and the sub-lever 51 are arranged with respect to the shaft 15 by inserting the shaft 15 into the respective connecting holes 50a and 51a. The lift lever 23 as a whole is integrated with the shaft 15 and
It is configured to rotate about 5.

The main lever 50 has a base portion 50b around the connecting hole 50a and two guide portions 50c (second guide portions) extending from the base portion 50b in the Y direction (another direction) in the drawing.
Are formed. In addition, the sub-lever 51 has a connection hole 5
A base portion 51b (base portion) around 1a and an arm portion 51c (arm portion) extending from the base portion 51b in the Y direction are formed. An engaging portion 51d is formed at the tip of the arm portion 51c. The arm portion 51c has flexibility, and the engaging portion 51 at the tip is centered around the base portion 51b.
It is configured to bend so that d moves in the vertical direction in FIG. The arm portion 51c includes two guide portions 50c.
It is arranged so that it may go along. Therefore, the arm 5
1c is a guide portion 50c for engaging the engaging portion 51d at the tip.
Is regulated so as not to bend in the direction of movement in the X direction (one direction) shown in FIG. The engaging portion 51d has a surface 51e (contact portion / first flat surface portion) substantially perpendicular to the X direction (see FIG. 9).
And a surface 51f (avoidance portion / second plane portion) (shown in FIG. 9) that is inclined with respect to the Y direction. In the present embodiment, the main lever 50 and the sub lever 5
Although 1 is a separate body, it may be an integral structure in which the base portion 50b and the base portion 51b are connected.

The operation of the door lock device 10 will be described below. FIG. 9 shows an unlocked state of the door lock device 10. In this state, when the outside door handle is operated, as in the first embodiment,
The link 22 moves from the unlock initial position in a substantially downward direction in FIG. As a result, the engaging portion 22b of the link 22 contacts the surface 51e of the engaging portion 51d and presses the surface 51e. This pressing direction substantially coincides with the X direction. As mentioned above,
The surface 51e is substantially perpendicular to the X direction, and the arm portion 51
Since c is guided by the guide portion 50c, the entire lift lever 23 rotates about the shaft 15 in the counterclockwise direction shown in FIG. As a result, as described above, the door is switched to the unlatched state and the door can be opened.

Next, as in the first embodiment, when the door lock device 10 is switched from the unlocked state to the locked state by the locking actuator or the like, the link 2
2 moves to the lock initial position. In this locked state, the link 22 is operated by operating the outside door handle.
FIG. 11 shows a state in which is moved. Engaging portion 22b at this time
Since the movement locus of is offset from the engaging portion 51d, the entire lift lever 23 does not operate by such an operation, and the latch 11 does not switch from the latched state to the unlatched state.

Next, the operation when the operation of the locking actuator or the like is applied in the state shown in FIG. 11 will be described. During this operation, as in the first embodiment,
The link 22 moves toward the unlocked full stroke position. That is, the link 22 moves in the substantially Y direction shown in FIG. At this time, the engaging portion 22b is the surface 51 of the engaging portion 51d.
Although engaged with f, the inclination of the surface 51f and the arm portion 51
Due to the bending of c, the contact between the engaging portion 22b and the surface 51f is avoided. At this time, this contact avoidance is more reliably performed by the bending of the arm portion 51c. The state is shown in FIG. In this state, when the operation of the outside door handle is returned to the original state, the door lock device 10 becomes the unlocked state shown in FIG.

As described above, in the locked state,
Even when the operation of the outside door handle or the like and the operation of the locking actuator or the like are superimposed, when the operation of the outside door handle or the like is returned to the original state, it is switched to the unlocked state. Therefore, it is not necessary to perform the switching operation to the unlocked state again, and the troublesome operation is suppressed. In addition, in the present embodiment, the link 22 is not divided in order to achieve this purpose (reduction of troublesome operation). Therefore, during the normal door opening operation, the link 22 moves the lift lever 2
3 The operation to operate the whole is stable. That is, in the present embodiment, during a normal door opening operation, the torque from the link 22 is transmitted to the main lever 50 without loss due to the set angle of the surface 51e and the configuration of the guide portion 50c. Therefore, the entire torque is stably transmitted from the outside door handle to the pole 12.

According to the present invention, the lift lever includes the main lever and the sub-lever which is arranged so as to be movable relative to the main lever and is engageable with the link member. That is, the sub-lever is configured to be operable independently of the main lever. Therefore, by operating the locking / unlocking member once, the link member can be moved independently of the main lever. As a result, since it is not necessary to operate the locking / unlocking member again, the troublesomeness of the operation can be suppressed. Further, in the present invention, since the link member is not divided, the operation of the lift lever of the link member becomes stable.

In the present invention, even if the link member moves in the other direction, the avoidance portion avoids the contact between the link member and the lift lever. Therefore, the link member can move regardless of the lift lever. Therefore, by operating the locking / unlocking member once, the link member can be moved regardless of the lift lever. As a result, since it is not necessary to operate the locking / unlocking member again, the troublesomeness of the operation can be suppressed. Further, in the present invention, since the link member is not divided, the operation of the lift lever of the link member becomes stable.
