Description

[Technical field]

[0001] The present invention relates to a vehicle door lock device. [Background technology]

[0002] Patent Document 1 discloses a door lock device (referred to as a "door latch device" in Patent Document 1) that is configured to perform a door close operation that switches the latch mechanism from a half-latched state to a full-latched state. Specifically, the door lock device of Patent Document 1 has a close lever that switches the latch mechanism from the half-latched state to the full-latched state by rotating. The close lever is connected to the door closer device by a close cable, and when the close cable is pulled by the door closer device, the close lever rotates and the latch mechanism switches from the half-latched state to the full-latched state.

[0003] The door lock device described in Patent Document 1 further has a cancel lever that rotates in conjunction with the operation of the door handle. The cancel lever of the door lock device and the door closer device are connected by a cancel cable, and when the cancel cable is pulled by the cancel lever of the door lock device, the action of pulling the close cable by the door closer device is stopped, and as a result, the door closing action of the door lock device is stopped (cancelled).

[0004] Patent Document 2 discloses a door lock device that has an actuator (motor) and can switch the latch mechanism from a half-latched state or a full-latched state to an unlatched state by the driving force of the actuator. According to the door lock device of Patent Document 2, a user can switch the latch mechanism from a half-latched state or a full-latched state to an unlatched state by operating an operation button (specifically, an electrical switch) or the like, that is, without manually operating the door handle.

[0005] [Patent Document 1] JP 2007-138534 A [Patent Document 2] JP 2021-055493 A Summary of the Invention

[0006] (Problem to be solved by the invention) Meanwhile, for a door lock device configured to be able to switch the state of the latch mechanism by the driving force of an actuator, there is a demand to be able to stop the door closing operation by operating an operation button, etc., in the same way as switching the state of the latch mechanism, that is, without manually operating the door handle. However, neither Patent Document 1 nor Patent Document 2 discloses a configuration for stopping the door closing operation by the driving force of an actuator.

[0007] The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a door lock device for a vehicle that can halt (cancel) a door closing operation by the driving force of an actuator.

[0008] (Means for solving the problem) In order to achieve the above object, the door lock device according to the present invention comprises: A door lock device for a vehicle is connected to a door closer device by a first connecting member and a second connecting member, the first connecting member being pulled and configured to eliminate a force pulling the first connecting member when the second connecting member is pulled, a latch that is movable between a full latch position that holds the vehicle door in a fully closed position, a half latch position that holds the vehicle door from moving from a half closed position to an open position, and an unlatched position that does not hold the vehicle door; a pawl movable between a restricting position where the pawl engages with the latch to hold the latch at the fully latched position and a non-restricting position where the pawl allows the latch to move from the fully latched position toward the unlatched position; a close lever connected to the first connecting member and configured to move from an initial position to a closed position when the first connecting member is pulled by the door closer device, the close lever moving the latch located at the half latch position to the full latch position when moving from the initial position to the closed position; A cancel lever connected to the second connecting member and configured to pull the second connecting member when moving from an initial position to a cancel position; a first member that is movable between a first position and a second position, and that moves the pole from the restricting position to the non-restricting position and moves the cancel lever from the initial position to the cancel position when the first member moves from the first position to the second position by a driving force of an actuator; Equipped with.

[0009] According to the door lock device of the present invention, the actuator of the door lock device can move the latch from the full latch position or half latch position to the unlatched position, and the door closing operation can be stopped. That is, according to the present invention, a "mechanism for stopping the door closing operation by the driving force of the actuator (without manual operation by the user)" can be added to a door lock device configured to switch the state of the latch mechanism by the driving force of the actuator. Therefore, according to the present invention, the user can move the latch from the full latch position or half latch position to the unlatched position and stop the door closing operation by operating, for example, an electrical switch for driving the actuator (i.e., without manual operation of the door handle).

[0010] And because the door closing operation can be stopped by the driving force of the actuator that moves the first member, there is no need for a separate actuator (an actuator separate from the actuator that moves the first member) for moving the cancel lever to the cancel position. Furthermore, because the cancel lever is moved from the initial position to the cancel position by the movement of the first member, there is no need to add a new member for transmitting the driving force of the actuator to the cancel lever. Therefore, it is possible to add a "mechanism for stopping the door closing operation by the driving force of the actuator" to the door lock device without increasing the number of parts or the size of the door lock device.

[0011] the first member is movable between the first position and the second position by rotating; the cancel lever is movable between the initial position and the cancel position by rotating about a straight line parallel to a rotation center line of the first member, and is disposed to face the first member along the direction of the rotation center line of the first member, The first member has an engagement portion having a protrusion shape that protrudes toward the cancel lever, and when the first member rotates from the first position to the second position, the engagement portion of the first member engages with the cancel lever, thereby moving the cancel lever from the initial position to the cancel position. The following configuration can be applied.

[0012] When the present invention is configured in this way, the first member directly contacts the cancel lever to move the cancel lever from the initial position to the cancel position. Therefore, a member (a member separate from the first member and the cancel lever) for transmitting the movement of the first member to the cancel lever is not required. Therefore, the number of parts is not increased and the door lock device is not enlarged. Furthermore, when the present invention is configured in this way, the movement of the first member can be transmitted to the cancel lever simply by adding an engagement portion to the first member (in other words, simply by changing the shape of the first member). Therefore, it is not necessary to change the arrangement of each member constituting the door lock device. Furthermore, it is not necessary to change the shape of any member other than the first member. Therefore, a "mechanism for stopping the door closing operation by the driving force of the actuator" can be easily added to the door lock device. Note that the "facing arrangement" referred to here means that the first member and the cancel lever are arranged so that they have portions facing each other in the direction of the rotation center line of the first member, and another member may be arranged between them as in the embodiment described later.

[0013] The cancel lever has a protruding engagement portion protruding toward the first member, When the first member rotates from the first position to the second position, the engagement portion of the first member engages with the engagement portion of the cancel lever, whereby the first member moves the cancel lever from the initial position to the cancel position. The following configuration can be applied.

[0014] When the present invention is configured in this manner, the movement of the first member can be transmitted to the cancel lever simply by changing the shapes of the first member and the cancel lever. Therefore, it is not necessary to change the arrangement of the members that configure the door lock device. Also, it is not necessary to change the shapes of members other than the first member and the cancel lever. Therefore, it is easy to add a "mechanism for canceling the door closing operation by the driving force of the actuator" to the door lock device.

[0015] The door lock device further includes a second member movable between a first position where the pole is engaged with the first member to hold the pole in a restricted position and a second position where the pole is permitted to move from the restricted position to a non-restricted position, the first member is movable from the first position to a third position past the second position, and when the first member moves from the first position to the third position past the second position, the second member is moved from the first position to the second position by pushing the second member; The following configuration can be applied.

[0016] A so-called double pole type door lock device has a second member that holds the pole in a restricted position, and is configured to move the second member from the first position to the second position by the first member. Therefore, by configuring the cancel lever to move from the initial position to the cancel position by the first member that moves the second member, it is possible to add a "mechanism that stops the door closing operation by the driving force of the actuator" to the double pole type door lock device.

[0017] The door lock device further includes a third member that moves from an initial position to an actuated position in response to an operation of a door handle provided on the vehicle door, When the third member moves from the initial position to the operating position, the third member engages with the cancel lever to move the cancel lever from the initial position to the cancel position. The following configuration can be applied.

[0018] With the invention thus configured, the cancel lever can be moved from the initial position to the cancel position by the operation of the door handle as well. Therefore, the door closing operation can be stopped by either the driving force of the door closer device or the manual operation of the door handle by the user. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, a door lock device 20 for a vehicle according to an embodiment of the present invention may be abbreviated to "door lock device 20". In the following description, the direction of the door lock device 20 and each member constituting the door lock device 20 is based on the direction of the vehicle 10. In each drawing, the front side of the door lock device 20 (i.e., the vehicle 10) is indicated by an arrow Fr, the rear side is indicated by an arrow Rr, the outer side in the vehicle width direction (left-right direction) is indicated by an arrow Out, the inner side in the vehicle width direction is indicated by an arrow In, the upper side is indicated by an arrow Up, and the lower side is indicated by an arrow Dw.

[0021] (Vehicles and vehicle doors) FIG. 1 is a schematic diagram showing a configuration example of a vehicle 10. As shown in FIG. 1, the vehicle 10 has a plurality of vehicle doors 12 attached to a vehicle body 11 so as to be openable and closable. The front end of each vehicle door 12 is rotatably attached to the vehicle body 11. Each vehicle door 12 can be moved between a closed position and an open position by rotating with respect to the vehicle body 11. The closed position is a position that closes an entrance (an opening provided in the vehicle body 11) for passengers to get on and off. The closed position includes a fully closed position that is one end position of the movable range of the vehicle door 12 and in which the entrance is securely closed, and a half-closed position that is a position slightly moved from the fully closed position to the other end side of the movable range and in which the entrance is incompletely closed. The open position is a position moved from the half-closed position to the other end side of the movable range. The open position can also be called a "position that does not close the entrance." The vehicle 10 is provided with a door sensor 14 (sometimes called a half-closed door sensor) that can detect when each vehicle door 12 is in a half-closed position.

[0022] A door lock device 20 and a door closer device 18 are attached to each vehicle door 12. The vehicle 10 has a door lock ECU 13 that controls the door lock device 20 and the door closer device 18. The door lock ECU 13 has a microcomputer. The microcomputer includes a CPU, a ROM, a RAM, a non-volatile memory, and an interface (I / F), etc. The CPU can read instructions, programs, or routines stored in the ROM, and deploy them in the RAM for execution. The door lock ECU 13 is also connected to each door sensor 14, and can obtain the detection result of each door sensor 14 as to "whether or not each vehicle door 12 is in the half-closed position."

[0023] FIG. 2 is a side view showing the configuration of the vehicle door 12. As shown in FIG. 2, the vehicle door 12 includes a door main body 121 constituting the lower half thereof and a door sash 122 constituting the upper half thereof. The door main body 121 has an outer panel 123, an inner panel 124, and a trim 125. The outer panel 123 is a member constituting the outer side surface of the door main body 121 (i.e., a part of the side surface of the vehicle 10). The inner panel 124 is a member attached to the inner side of the outer panel 123. The trim 125 is a resin member constituting the inner side surface of the door main body 121 and is attached to the inner side of the inner panel 124.

[0024] An outside door handle 15 is attached to the outer panel 123. An inside door handle 16 is attached to the inner panel 124. The outside door handle 15 and the inside door handle 16 are operating members that can be manually operated by a user. Both the outside door handle 15 and the inside door handle 16 are configured to be movable between an initial position and an actuated position, and are constantly elastically biased toward the initial position by a spring or the like (not shown). The user can move the outside door handle 15 and the inside door handle 16 from the initial position to the actuated position against the biasing force of the spring or the like. In the following description, the manual operation of moving each of the outside door handle 15 and the inside door handle 16 from the initial position to the actuated position is referred to as a "manual door opening operation."

[0025] Furthermore, the inner panel 124 is provided with an unlatch switch 17, which is an electric switch that can be operated by the user. The unlatch switch 17 is operated to switch a latch mechanism 21 of a door lock device 20 (described later) from a latched state to an unlatched state, and to stop a door closing operation (described later). The unlatch switch 17 is connected to the door lock ECU 13, and the door lock ECU 13 can detect that the unlatch switch 17 has been operated.

[0026] (Outline of door lock device and door closer device) The door lock device 20 and the door closer device 18 are disposed between an outer panel 123 and an inner panel 124 of the vehicle door 12 (i.e., in the internal space of the door main body 121) and are fixed to the inner panel 124. A part of the door lock device 20 is exposed to the outside of the vehicle door 12 at the rear end of the vehicle door 12. The door lock device 20 and the door closer device 18 are connected by a close cable 81 which is an example of a first connecting member and a cancel cable 82 which is an example of a second connecting member.

[0027] Fig. 3 to Fig. 6 are diagrams showing the configuration of the main parts of the door lock device 20. Fig. 3 is a perspective view, Fig. 4 is a view seen from the rear side, Fig. 5 is a view seen from the front side, and Fig. 6 is a view seen from outside the vehicle. As shown in these figures, the door lock device 20 has a latch mechanism 21, an electric operation mechanism 22, a manual operation mechanism 23, a closer mechanism 24, and a cancel mechanism 25.

[0028] The latch mechanism 21 of the door lock device 20 is configured to be able to switch from a latched state to an unlatched state by a manual door opening operation by a user and a driving force of an actuator of the door lock device 20. The latched state of the latch mechanism 21 is a state in which the vehicle door 12 located in the closed position is held so as not to move to an open position. Specifically, the latched state is a state in which the latch 31 of the latch mechanism 21 is located in a latched position described later, and the latch 31 holds (engages) a striker 101 provided on the vehicle body 11. The latched state includes a full latched state in which the vehicle door 12 is held in a fully closed position, and a half latched state in which the vehicle door 12 is held so as not to move from a half closed position to an open position. The unlatched state is a state in which the vehicle door 12 is not held (in other words, a state in which the vehicle door 12 is allowed to move to an open position). Specifically, the unlatched state is a state in which the latch 31 is located in an unlatched position described later, and the latch 31 is freely engaged with and disengaged from the striker 101.

[0029] The door closer device 18 is configured to be able to pull the close cable 81 by the driving force of an actuator possessed by the door closer device 18. Furthermore, the door closer device 18 is configured to eliminate the pulling force of the close cable 81 when the cancel cable 82 is pulled (it is also possible to stop the action of pulling the close cable 81, or to eliminate the tension applied to the close cable 81). For example, a vehicle door closer device described in JP 2007-138534 A and a vehicle door lock device described in JP 2013-019215 A can be applied to such a door closer device 18.

[0030] The door lock device 20 is configured such that when the vehicle door 12 is in the half-closed position and the latch mechanism 21 is in the half-latched state, if the close cable 81 is pulled by the door closer device 18, the latch mechanism 21 switches from the half-latched state to the full-latched state. In the following description, the operation of switching the latch mechanism 21 from the half-latched state to the full-latched state by the driving force of the door closer device 18 is referred to as the "door closing operation." Furthermore, the door lock device 20 is configured such that the door closer device 18 stops (cancels) the operation of pulling the close cable 81 by pulling the cancel cable 82 during the door closing operation, that is, the door closing operation is stopped.

[0031] (Latch mechanism) The latch mechanism 21 includes a latch 31, a pole 32, a pole lift lever 33, a half latch lever 34, a block lever 35, and a block lift lever 36.

[0032] The latch 31 has a full latch claw 311, a half latch claw 312, a striker holding groove 313, and a close claw 314. The full latch claw 311 is a portion that can be engaged with an engagement portion 321 of the pole 32, which will be described later. The half latch claw 312 is a portion that can be engaged with a second engagement portion 342 of the half latch lever 34, which will be described later. The striker holding groove 313 is a groove (which can also be called a notch) into which the striker 101 provided on the vehicle body 11 can be inserted and removed. The striker holding groove 313 is provided between the full latch claw 311 and the half latch claw 312. The close claw 314 is a portion that can be engaged with the close lever 61, which will be described later.

[0033] The latch 31 is supported on a base plate (not shown) so as to be rotatable about a straight line C1 that is substantially parallel to the front-rear direction. The latch 31 can move to a full latch position, a half latch position, and an unlatched position (sometimes referred to as a release position) by rotating. The full latch position is a position where the latch 31 holds the striker 101 when the vehicle door 12 is in a fully closed position (in other words, a position where the latch 31 engages with the striker 101). FIGS. 3 to 6 show a state where the latch 31 is in the full latch position. The half latch position is a position where the latch 31 holds the striker 101 when the vehicle door 12 is in a half closed position. When the latch 31 is in the half latch position, the latch 31 holds the vehicle door 12 so as not to move from the half closed position to the open position. In FIG. 4, the half latch position is a position where the latch 31 is rotated a predetermined angle in a clockwise direction from the full latch position. The unlatched position is a position where the latch 31 does not hold the striker 101 provided on the vehicle body 11 (in other words, a position where the latch 31 can be freely engaged with and disengaged from the striker 101). That is, the unlatched position is a position where the latch 31 does not hold the vehicle door 12. In Fig. 4, the unlatched position is a position where the latch 31 has further rotated a predetermined angle in the clockwise direction from the half-latched position. The latch 31 is constantly elastically biased toward the unlatched position (clockwise direction in Fig. 4) by a latch return spring (not shown).

[0034] The pole 32 has an engagement portion 321 that can be engaged with and disengaged from the full latch claw 311 of the latch 31 and the engagement portion 351 of the block lever 35. The pole 32 is supported on the base plate so as to be rotatable integrally with and coaxially with the pole lift lever 33 described later, centered on a straight line C2 parallel to the rotation center line C1 of the latch 31. The pole 32 can be moved between a restricted position and a non-restricted position by rotating. The restricted position of the pole 32 is a position where the engagement portion 321 of the pole 32 engages with the full latch claw 311 of the latch 31 when the latch 31 is located at the full latch position. Specifically, the restricted position of the pole 32 is a position at one end of a range in which the pole 32 can rotate, and is a position where the engagement portion 321 of the pole 32 is inside the rotational movement trajectory of the full latch claw 311 of the latch 31. When the pole 32 is in the restricted position, the engaging portion 321 of the pole 32 engages with the full latch claw 311 of the latch 31, thereby holding the latch 31 in the full latch position (i.e., restricting the movement of the latch 31 from the full latch position toward the unlatched position). FIG. 4 shows the state in which the pole 32 is in the restricted position. The non-restricted position of the pole 32 is a position that allows the latch 31 to move from the full latch position toward the unlatched position. Specifically, the non-restricted position is a position in which the pole 32 is located outside the rotation trajectory of the full latch claw 311 of the latch 31, and is a position in which the pole 32 in the restricted position in FIG. 4 has rotated a predetermined angle in the clockwise direction. The pole 32 is constantly elastically biased toward the non-restricted position by a pole return spring (not shown).

[0035] The pole lift lever 33 is supported on the base plate so as to be rotatable coaxially with the pole 32. The pole lift lever 33 is connected to the pole 32 so as to rotate integrally with the pole 32. In other words, the pole lift lever 33 can move integrally with the pole 32 between the restricted position and the non-restricted position.

[0036] The half latch lever 34 has a first engagement portion 341 and a second engagement portion 342. The first engagement portion 341 is a portion that can be engaged with a first engagement portion 361 of the block lift lever 36 described later, and is specifically a groove having an inner peripheral surface on which the first engagement portion 361 of the block lift lever 36 can slide. The second engagement portion 342 is a portion that can be engaged with a half latch claw 312 of the latch 31. The half latch lever 34 is supported on the base plate so as to be rotatable about a straight line C3 parallel to the rotation center line C1 of the latch 31, and rotates in conjunction with the rotation of the block lift lever 36 described later. The half latch lever 34 can be moved between a restricted position and a non-restricted position by rotating.

[0037] The restricted position of the half latch lever 34 is a position where the second engagement portion 342 of the half latch lever 34 can engage with the half latch claw 312 of the latch 31. Specifically, the restricted position of the half latch lever 34 is a position where the second engagement portion 342 of the half latch lever 34 is inside the rotation trajectory of the half latch claw 312 of the latch 31. When the half latch lever 34 is located at the restricted position, the second engagement portion 342 of the half latch lever 34 engages with the half latch claw 312 of the latch 31, thereby restricting the latch 31 from moving from the half latch position toward the unlatched position. The non-restricted position is a position where the latch 31 is allowed to move from the half latch position toward the unlatched position. Specifically, the non-restricted position of the half latch lever 34 is a position where the second engagement portion 342 of the half latch lever 34 does not engage with the half latch claw 312 of the latch 31.

[0038] The block lever 35 is an example of the second member. The block lever 35 has an engagement portion 351 that can be engaged with and disengaged from the engagement portion 321 of the pole 32. The block lever 35 is supported rotatably around a straight line C4 parallel to the rotation center line C1 of the latch 31 with respect to the base plate, and can be rotated between a first position and a second position. The first position of the block lever 35 is a position where the engagement portion 351 of the block lever 35 engages with the engagement portion 321 of the pole 32 to hold the pole 32 in the restricted position (in other words, the movement of the pole 32 from the restricted position to the non-restricted position is restricted). Specifically, the first position of the block lever 35 is a position where the engagement portion 351 of the block lever 35 is inside the rotation movement locus of the engagement portion 321 of the pole 32. Note that FIG. 4 shows a state where the block lever 35 is located at the first position. The second position of the block lever 35 is a position where the pole 32 is allowed to move from the restricted position to the non-restricted position. Specifically, the second position of the block lever 35 is a position where the block lever 35 is located outside the trajectory of the rotational movement of the pole 32. In Fig. 4, the second position is a position rotated a predetermined angle in a clockwise direction from the first position. Note that the second position of the block lever 35 is not a specific point but has a predetermined range. The block lever 35 is constantly elastically biased toward the first position by the biasing force of a block lever return spring (not shown).

[0039] The block lift lever 36 is an example of the first member. The block lift lever 36 is supported on the base plate so as to be rotatable coaxially with the block lever 35. The block lift lever 36 is disposed adjacent to the block lever 35 on the front side of the block lever 35. The block lift lever 36 can be moved to a first position, a second position, and a third position by rotating. The first position of the block lift lever 36 is one end position of the range of rotational movement. FIG. 4 shows the state where the block lift lever 36 is located at the first position. The second position is an intermediate position of the range of rotational movement, and the third position is the other end position (the end opposite to the first position) of the range of rotational movement. In FIG. 4, the second position is a position rotated a predetermined angle in the clockwise direction from the first position, and the third position is a position rotated a further predetermined angle in the clockwise direction from the second position. The block lift lever 36 is constantly elastically biased toward the first position by a block lift lever return spring (not shown).

[0040] The block lift lever 36 has a first engagement portion 361, a second engagement portion 362, a third engagement portion 363, a fourth engagement portion 364, and a fifth engagement portion 365. The first engagement portion 361 of the block lift lever 36 is a portion that engages with the half latch lever 34. Specifically, the first engagement portion 361 of the block lift lever 36 has an arm-shaped portion that extends radially outward of a circle centered on the rotation center line C4 of the block lever 35 and the block lift lever 36, and a protruding portion that is provided at the tip of the arm-shaped portion and protrudes in a direction parallel to the rotation center line C4. The protruding portion is inserted into the first engagement portion 341 of the half latch lever 34. Therefore, the block lift lever 36 and the half latch lever 34 rotate in conjunction with each other. When the block lift lever 36 is located at the first position, the half latch lever 34 is located at the restricted position, and when the block lift lever 36 is located at either the second position or the third position, the half latch lever 34 is located at the non-restricted position.

[0041] The second engagement portion 362 of the block lift lever 36 is a portion that can be engaged with and disengaged from the release lever 44, and has a protrusion-like configuration that protrudes forward as shown in Fig. 3. A second engagement portion 442 of the release lever 44, which will be described later, can abut against the underside of the second engagement portion 362. The second engagement portion 362 of the block lift lever 36 is located on the vehicle inner side of the rotation center line C4. The block lift lever 36 moves from the first position to the second position and to the third position by the second engagement portion 362 moving in the upward direction.

[0042] The third engagement portion 363 of the block lift lever 36 is a portion that can be freely engaged with and disengaged from the block lever 35. The third engagement portion 363 has a protrusion-like configuration that protrudes toward the rear side (i.e., the side where the block lever 35 is disposed). When the block lift lever 36 moves from the first position to the second position (or moves beyond the second position to the third position), the third engagement portion 363 comes into contact with the block lever 35 and pushes the block lever 35, moving the block lever 35 from the first position to the second position.

[0043] The fourth engagement portion 364 is a portion that can be engaged with and disengaged from the pole lift lever 33, and has an arm-like (or protruding) configuration that extends radially outward from a circle centered on the rotation center line of the block lever 35 and the block lift lever 36. When the block lift lever 36 is in the first or second position, the fourth engagement portion 364 does not abut (engage) with the pole lift lever 33 and is separated from the pole lift lever 33. When the block lift lever 36 moves from the first position to the third position beyond the second position, the fourth engagement portion 364 rises and abuts against the pole lift lever 33, pushing the pole lift lever 33. At this time, the block lever 35 is already in the second position, and the pole 32 is allowed to move from the restricted position to the non-restricted position. Therefore, when the pole lift lever 33 is pushed by the fourth engagement portion 364 of the block lift lever 36, the pole lift lever 33 and the pole 32 move from the restricted position to the non-restricted position.

[0044] The fifth engagement portion 365 is a portion that can engage with the second engagement portion 713 of the cancel lever 71, which will be described later. As shown in FIG. 5, the fifth engagement portion 365 has a protruding configuration that protrudes toward the front side (i.e., the side where the cancel lever 71 is arranged). The fifth engagement portion 365 is located on the vehicle inner side (the same side as the second engagement portion 362) of the rotation center line C4. Therefore, when the pole lift lever 33 moves from the first position to the second position and the third position, the fifth engagement portion 365 rises.

[0045] Next, the operation of the latch mechanism 21 will be described. When the vehicle door 12 is in the open position, the latch 31 is held in the unlatched position by the biasing force of the latch return spring. When the latch 31 is in the unlatched position, the vehicle door 12 is in a state in which it can be opened and closed. This state is the unlatched state of the latch mechanism 21.

[0046] When the vehicle door 12 moves from the open position toward the half-closed position (so-called "half-door" position), the striker 101 enters the striker retaining groove 313 of the latch 31, and the latch 31 is pushed by the striker 101 to move toward the half-latch position. At this time, the latch 31 pushes the second engagement portion 342 of the half latch lever 34 to move the half latch lever 34 from the restricted position to the non-restricted position. Then, when the half latch lever 34 moves to the non-restricted position, the block lift lever 36 moves to the second position in conjunction with the half latch lever 34. At this time, the third engagement portion 363 of the block lift lever 36 pushes the block lever 35 to move the block lever 35 from the first position to the second position. Furthermore, the full latch claw 311 of the latch 31 pushes the pole 32 to move the pole 32 from the restricted position to the non-restricted position.

[0047] When the vehicle door 12 reaches the half-closed position, the latch 31 is in the half-latched position. Then, the half-latch lever 34 moves to the restricted position by the biasing force of the half-latch lever return spring, and the second engagement portion 342 of the half-latch lever 34 engages with the half-latch claw 312 of the latch 31. Therefore, the movement of the latch 31 from the half-latch position to the unlatched position is restricted. Furthermore, when the latch 31 is in the half-latch position, the full-latch claw 311 pushes the pole 32 to hold the pole 32 in the unrestricted position. Also, the block lift lever 36 moves to the first position in conjunction with the movement of the half-latch lever 34. However, the block lever 35 is prevented from moving to the restricted position by the pole 32 and is held in the unrestricted position. This state is the half-latch state of the latch mechanism 21. When the latch mechanism 21 is in the half-latch state, the movement of the latch 31 from the half-latch position to the unlatch position is restricted by the half-latch claw 312. Therefore, the striker 101 cannot come out of the striker holding groove 313, and the vehicle door 12 is held in the half-closed position by the latch 31 (however, movement from the half-closed position to the fully-closed position is permitted).

[0048] When the vehicle door 12 moves from the half-closed position toward the fully-closed position, the latch 31 is pushed by the striker 101 and moves from the half-latched position toward the fully-latched position. Then, when the latch 31 is in the fully-latched position, the engagement between the pole 32 and the full-latch claw 311 is released, and the pole 32 moves to the restricted position by the biasing force of the pole return spring, and the block lever 35 moves from the non-restricted position to the restricted position by the biasing force of the block lever return spring. Therefore, the pole 32 holds the latch 31 at the fully-latched position at the restricted position, and the block lever 35 holds the pole 32 at the restricted position at the first position. Therefore, the latch 31 is held at the fully-latched position and is restricted from moving toward the half-latched position and the unlatched position. This state is the fully-latched state of the latch mechanism 21. When the latch mechanism 21 is in the fully-latched state, the movement of the latch 31 from the fully-latched position to the unlatched position is restricted by the pole 32 and the block lever 35. Therefore, the striker 101 cannot come out of the striker holding groove 313, and the vehicle door 12 is held in the fully closed position by the latch 31.

[0049] To switch the latch mechanism 21 from the full latched state or the half latched state to the unlatched state, the block lift lever 36 is moved from the first position past the second position to the third position. When the latch mechanism 21 is in the full latched state or the half latched state, if the block lift lever 36 is moved from the first position to the second position, the half latch lever 34 moves in conjunction with the block lift lever 36 to the non-restricted position. In addition, the block lever 35 is pushed by the block lift lever 36 to move from the first position to the second position. Therefore, the half latch lever 34 is in a state that allows the latch 31 to move to the unlatched position, and the block lever 35 is in a state that allows the pole 32 to move from the restricted position to the non-restricted position. Furthermore, when the block lift lever 36 is moved to the third position past the second position, the third engagement portion 363 of the block lift lever 36 pushes the pole lift lever 33, and moves the pole 32 together with the pole lift lever 33 from the restricted position to the non-restricted position. Therefore, the pole 32 is in a state that allows the latch 31 to move to the unlatched position. Therefore, the latch 31 moves from the full latched position or the half latched position to the unlatched position due to the biasing force of the latch return spring, and as a result, the latch mechanism 21 switches to the unlatched state.

[0050] (Electric operation mechanism) The electric operation mechanism 22 is configured to be able to switch the latch mechanism 21 from a latched state to an unlatched state by the driving force of the actuator. Furthermore, the electric operation mechanism 22 is configured to be able to pull the cancel cable 82 by the driving force of the actuator. The electric operation mechanism 22 has a motor 41 which is an example of an actuator, a worm wheel 43 which rotates in response to the rotational power output by the motor 41, and a release lever 44 which moves by the rotation of the worm wheel 43.

[0051] The motor 41 is attached to the housing of the door lock device 20. The motor 41 has a rotating shaft to which a worm 42 is attached.

[0052] The worm wheel 43 is supported on the housing of the door lock device 20 so as to be rotatable about a straight line C5 (i.e., a straight line substantially perpendicular to the rotation center line C4 of the block lift lever 36) substantially parallel to the vehicle width direction. The worm wheel 43 is located forward of the block lift lever 36 and is located on the vehicle inner side of the rotation center line C4 of the block lift lever 36. The worm wheel 43 is engaged with a worm 42 attached to a rotating shaft of the motor 41 and configured to rotate by a rotational driving force outputted by the motor 41. The worm wheel 43 can move between a neutral position and a release position by rotating. The worm wheel 43 is constantly elastically biased toward the neutral position by a return spring (not shown), and is held in the neutral position by the biasing force of the return spring while the motor 41 is not operating. The worm 42 and the worm wheel 43 are configured to be capable of being driven in reverse so that the worm wheel 43 can move from the release position to the neutral position by the biasing force of the biasing spring.

[0053] The worm wheel 43 is provided with an engagement portion 431. The engagement portion 431 of the worm wheel 43 is a portion that can be engaged with and disengaged from a first engagement portion 441 of the release lever 44, and has a protruding configuration that protrudes from the surface of the worm wheel 43 facing the vehicle exterior toward the vehicle exterior (i.e., toward the side where the rotation center line C4 of the block lift lever 36 is located). When the worm wheel 43 moves from the neutral position toward the release position, the engagement portion 431 of the worm wheel 43 descends.

[0054] The release lever 44 is disposed in front of the block lift lever 36 and on the vehicle exterior side of the worm wheel 43. The release lever 44 is supported by the housing of the door lock device 20 so as to be rotatable about a straight line C6 parallel to the rotation center line C5 of the worm wheel 43. Specifically, a shaft hole penetrating in the vehicle width direction is provided in the middle part of the release lever 44 in the front-rear direction, and the release lever 44 is supported rotatably about the shaft hole by a support shaft (not shown) inserted into the shaft hole. The release lever 44 can be moved between a neutral position and a release position by rotating. The release lever 44 has a first engagement portion 441 provided in front of the shaft hole and a second engagement portion 442 provided behind the shaft hole. The first engagement portion 441 of the release lever 44 has a flat plate-like configuration extending toward the vehicle exterior. The first engagement portion 441 of the release lever 44 is located below the engagement portion 431 of the worm wheel 43. The second engagement portion 442 of the release lever 44 has a flat plate-shaped portion extending toward the outside of the vehicle. The second engagement portion 442 of the release lever 44 is located below the second engagement portion 362 of the block lift lever 36.

[0055] When the worm wheel 43 moves from the neutral position to the release position by the driving force of the motor 41, the first engagement portion 441 of the release lever 44 is pushed down by the engagement portion 431 of the worm wheel 43, and the second engagement portion 442 of the release lever 44 rises. In other words, the release lever 44 moves from the neutral position to the release position. Then, the second engagement portion 442 of the release lever 44 pushes up the second engagement portion 362 of the block lift lever 36. When the block lift lever 36 moves from the first position to the third position beyond the second position, the latch mechanism 21 switches from the fully latched state to the unlatched state as described above.

[0056] When the motor 41 stops after the latch mechanism 21 switches to the unlatched state, the worm wheel 43 moves from the release position to the neutral position by the biasing force of the return spring. As a result, the second engagement portion 362 of the block lift lever 36 is no longer pressed by the second engagement portion 442 of the release lever 44, so the block lift lever 36 moves to the first position by the biasing force of the block lift lever return spring. Also, the release lever 44 is pressed by the block lift lever 36 and moves to the neutral position.

[0057] (manual operation mechanism) The manual operation mechanism 23 is configured to switch the latch mechanism 21 from a fully latched or half latched state to an unlatched state by a manual door opening operation, and to move a cancel lever 71 (described later) from an initial position to a cancel position.

[0058] The manual operation mechanism 23 includes an open lever 51, which is an example of a third member. The open lever 51 is supported on the base plate so as to be rotatable about a straight line C7 parallel to the rotation center line C4 of the block lift lever 36. The open lever 51 can be moved between an initial position and an actuated position by rotating. The open lever 51 is made of a metal plate and manufactured by pressing. The open lever 51 has a long plate shape and is arranged so that its long dimension is approximately parallel to the vehicle width direction. An axial hole is provided at approximately the center of the long dimension direction (i.e., the vehicle width direction) of the open lever 51. The open lever 51 is rotatably supported by a support shaft (not shown) inserted through the axial hole. The open lever 51 is provided adjacent to the front side of the block lift lever 36.

[0059] The open lever 51 has a first engagement portion 511 and a second engagement portion 512. The first engagement portion 511 has a flat plate shape extending toward the front side, and the open rod 83 (see FIG. 8A) can be engaged with its upper surface. The second engagement portion 512 has a flat plate shape extending toward the rear side (i.e., the side where the block lift lever 36 is arranged). The second engagement portion 512 is located below a portion of the rotation center line C4 of the block lift lever 36 on the vehicle inner side.

[0060] The open lever 51 can be moved between an initial position and an actuated position by rotating. The initial position of the open lever 51 is a position where the second engagement portion 512 of the open lever 51 is spaced downward from the lower end of the block lift lever 36 that is located at the first position. The rotated position of the open lever 51 shown in FIG. 5 is the initial position. The actuated position of the open lever 51 is a position where the open lever 51 is rotated from the initial position in a direction where the first engagement portion 511 is lowered and the second engagement portion 512 is raised. The position where the open lever 51 is rotated counterclockwise by a predetermined angle from the initial position shown in FIG. 5 is the actuated position.

[0061] The open rod 83 is linked to the outside door handle 15 and the inside door handle 16. The open rod 83 is configured to move down when at least one of the outside door handle 15 and the inside door handle 16 is operated to open the door manually. Therefore, when the outside door handle 15 or the inside door handle 16 is operated to open the door manually, the first engagement portion 511 of the open lever 51 is pushed downward by the open rod 83, and the open lever 51 moves from the initial position to the operating position. The open lever 51 is constantly elastically biased toward the initial position by the open lever return spring. Therefore, the open lever 51 is located at the initial position while the door is not being operated to open the door manually.

[0062] When the open lever 51 moves from the initial position to the actuated position, the second engagement portion 512 of the open lever 51 comes into contact with the lower end (lower surface) of the block lift lever 36 and pushes up the block lift lever 36, moving the block lift lever 36 from the first position, past the second position, to the third position. In addition, when the open lever 51 moves from the initial position to the actuated position, the lower end (lower surface) of the open lever 51 pushes down the first engagement portion 712 of the cancel lever 71, moving the cancel lever 71 from the initial position to the cancel position.

[0063] (Closer mechanism) The closer mechanism 24 is a mechanism that switches the latch mechanism 21 from a half-latched state to a fully-latched state by the driving force of the door closer device 18 when the vehicle door 12 is in a half-closed position and the latch mechanism 21 is in a half-latched state (when the vehicle door 12 is in a so-called "half-door" state).

[0064] The closer mechanism 24 has a close lever 61. The close lever 61 is supported on the base plate so as to be rotatable about a straight line C8 parallel to the rotation center line C1 of the latch 31. The close lever 61 has an engagement portion 611. The engagement portion 611 is a plate-shaped portion extending radially outward from a circle centered on the rotation center line C8, and is configured to be engageable with and disengageable from the close claw 314 of the latch 31. The close lever 61 can be moved between an initial position and a closed position by rotating. The initial position is a position where the engagement portion 611 is not in contact with the close claw 314 of the latch 31 but is separated therefrom. When the close lever 61 moves from the initial position to the closed position, it abuts against the close claw 314 of the latch 31, which is positioned at the half latch position, and pushes the close claw 314, thereby moving the latch 31 from the half latch position to the full latch position.

[0065] One end of a close cable 81 is connected to the close lever 61. When the close cable 81 is pulled by the door closer device 18, the close lever 61 rotates from the initial position to the close operating position. The close lever 61 is constantly elastically biased toward the initial position by a close lever return spring (not shown).

[0066] Here, the door closing operation will be described. The door lock ECU 13 continuously judges whether or not the condition for executing the door closing operation for each vehicle door 12 is satisfied. For example, the door lock ECU 13 acquires the detection results of each door sensor 14, and when there is a vehicle door 12 located in a half-closed position, it judges that the condition for executing the door closing operation for the vehicle door 12 is satisfied. Then, the door lock ECU 13 operates the actuator of the door closer device 18 of the vehicle door 12 for which the condition for executing the door closing operation is satisfied. As a result, the close cable 81 is pulled, and the close lever 61 of the door lock device 20 moves from the initial position toward the close position. Therefore, the latch 31 moves from the half latch position toward the full latch position. At this time, the striker 101 that is inserted into the striker holding groove 313 is pushed toward the outside of the vehicle as the latch 31 rotates, and the vehicle door 12 moves from the half-closed position toward the fully closed position due to the reaction force. When the latch 31 is in the fully latched position, as described above, the latch mechanism 21 is in the fully latched state and the vehicle door 12 is in the fully closed position. After that, the door lock ECU 13 stops the operation of the actuator of the door closer device 18.

[0067] (Cancellation mechanism) The cancel mechanism 25 is configured to be able to pull the cancel cable 82 in order to stop the door closing operation. The action of pulling the cancel cable 82 is referred to as the "cancel operation." The cancel mechanism 25 has a cancel lever 71. An end of the cancel cable 82 is connected to the cancel lever 71, and the cancel lever 71 is configured to rotate to pull the cancel cable 82.

[0068] The cancel lever 71 is supported rotatably coaxially with the open lever 51. Specifically, the cancel lever 71 has an axial hole penetrating in the front-rear direction, and a support shaft that supports the open lever 51 and the cancel lever 71 coaxially and rotatably is inserted into the axial hole. The cancel lever 71 is disposed adjacent to the open lever 51 on the front side of the open lever 51. Therefore, the open lever 51 is disposed on the front side of the block lift lever 36, and the cancel lever 71 is disposed further in front of the open lever 51. That is, the cancel lever 71 is disposed facing the block lift lever 36 along the direction of the rotation center line C4 of the block lift lever 36. The term "facing" refers to the relationship between the block lift lever 36 and the cancel lever 71 being disposed such that they have portions that face each other in the direction of the rotation center line C4 of the block lift lever 36, and the open lever 51, which is a separate member, may be disposed between the two.

[0069] The cancel lever 71 has a cancel cable connecting portion 711, a first engaging portion 712, and a second engaging portion 713. An end of the cancel cable 82 is connected to the cancel cable connecting portion 711. The first engaging portion 712 of the cancel lever 71 is a portion that can be engaged with and disengaged from the lower end (lower surface) of the open lever 51. Specifically, the first engaging portion 712 has a plate-like configuration that extends toward the rear side (i.e., the side where the open lever 51 is arranged), and is located below the open lever 51. The second engaging portion 713 of the cancel lever 71 is a portion that can be engaged with and disengaged from the fifth engaging portion 365 of the block lift lever 36. Specifically, the second engaging portion 713 has a protruding shape (specifically, a flat plate-like shape that extends toward the rear side) that protrudes toward the rear side (i.e., the side where the block lift lever 36 is arranged). Since the open lever 51 is disposed between the cancel lever 71 and the block lift lever 36, the second engagement portion 713 of the cancel lever 71 is provided at a position spaced above the open lever 51 so as not to interfere with the open lever 51. Furthermore, the rear end portion of the second engagement portion 713 of the cancel lever 71 is located rearward of the open lever 51. The rear end portion of the second engagement portion 713 is located above the fifth engagement portion 365 of the block lift lever 36.

[0070] The cancel lever 71 can be rotated between an initial position and a cancel position by rotating. The initial position of the cancel lever 71 is a position where the cancel cable 82 is not pulled (no tension is applied to the cancel cable 82), the first engagement portion 712 is not engaged with the open lever 51 located at the initial position, and the second engagement portion 713 is not engaged with the fifth engagement portion 365 of the block lift lever 36 located at the initial position (a position separated from the fifth engagement portion 365). The cancel position is a position rotated a predetermined angle from the initial position in a direction in which the first engagement portion 712 descends and the cancel cable connecting portion 711 and the second engagement portion 713 ascend. The cancel cable connecting portion 711 and the second engagement portion 713 are provided on the vehicle inner side of the rotation center line C7, and the first engagement portion 712 is provided on the vehicle outer side of the rotation center line C7. Then, when the cancel lever 71 moves from the initial position to the cancel position (i.e., when the first engagement portion 712 rotates in the direction in which it rises and the second engagement portion 713 descends), the cancel cable connection portion 711 rises and pulls the cancel cable 82 connected to the cancel cable connection portion 711.

[0071] Next, a description will be given of the operation of the cancel mechanism 25. In this embodiment, the door closing operation can be canceled by either the manual door opening operation or the driving force of the motor 41.

[0072] (Cancellation action by motor driving force) 7A and 7B are diagrams showing a cancel operation by the driving force of the motor 41. When the door lock ECU 13 detects that the unlatch switch 17 has been operated, it operates the motor 41 to move the worm wheel 43 from the neutral position to the release position. When the motor 41 operates and the worm wheel 43 moves from the neutral position to the release position, the second engagement portion 442 of the release lever 44 pushes up the second engagement portion 362 of the block lift lever 36. Therefore, as shown in FIG. 7A, the block lift lever 36 moves from the first position to the third position (rotates counterclockwise in FIG. 7A). Since the second engagement portion 713 of the cancel lever 71 is located above the fifth engagement portion 365 of the block lift lever 36, when the block lift lever 36 moves from the first position to the third position, the fifth engagement portion 365 of the block lift lever 36 engages (abuts) with the second engagement portion 713 of the cancel lever 71. When the block lift lever 36 rotates further from the position shown in FIG. 7A toward the third position, the fifth engagement portion 365 of the block lift lever 36 pushes up the second engagement portion 173 of the cancel lever 71. As a result, the cancel lever 71 rotates from the initial position toward the cancel position. Then, as shown in FIG. 7B, when the block lift lever 36 reaches the third position, the cancel lever 71 reaches the cancel position. When the cancel lever 71 moves from the initial position to the cancel position (in other words, when the cancel cable 82 is pulled), the force of the door closer device 18 to pull the close cable 81 is lost. Therefore, by operating the unlatch switch 17 during the door closing operation, the door closing operation is canceled.

[0073] In addition, since the first engagement portion 712 of the cancel lever 71 is located below the open lever 51, when the cancel lever 71 moves from the initial position to the cancel position, the first engagement portion 712 of the cancel lever 71 moves in a direction away from the open lever 51. Therefore, the open lever 51 does not interfere with the cancel lever 71.

[0074] (Cancellation action by manual door opening) 8A and 8B are diagrams showing a cancel operation due to a manual door opening operation. When a manual door opening operation is performed, as shown in FIG. 8A, the open rod 83 comes into contact with the upper surface of the first engagement portion 511 of the open lever 51 and presses down the first engagement portion 511 of the open lever 51. As a result, the open lever 51 moves from the initial position toward the operating position. Then, as shown in FIG. 8A, when the open lever 51 moves from the initial position toward the operating position, the lower end (lower surface) of the open lever 51 comes into contact with the first engagement portion 712 of the cancel lever 71.

[0075] When the open lever 51 rotates further from the position shown in Fig. 8A toward the operating position, the lower end of the open lever 51 presses down the first engagement portion 712 of the cancel lever 71. Then, as shown in Fig. 8B, when the open lever 51 moves to the operating position, the cancel lever 71 moves to the cancel position. When the cancel lever 71 moves from the initial position to the cancel position, the force of the door closer device 18 pulling the close cable 81 is lost. Therefore, by performing a manual door opening operation during the door closing operation, the door closing operation is canceled.

[0076] The second engagement portion 713 of the cancel lever 71 is located above the open lever 51, on the vehicle inner side of the rotation center line C7. Therefore, when the cancel lever 71 moves from the initial position to the cancel position, the open lever 51 does not interfere with the operation of the cancel lever 71. In addition, the front end of the fifth engagement portion 365 of the block lift lever 36 is located rearward of the open lever 51. Therefore, the open lever 51 and the block lift lever 36 do not interfere with each other.

[0077] According to the door lock device 20 of this embodiment, the driving force of the motor 41, which is an example of an actuator of the door lock device 20, can switch the latch mechanism 21 from a latched state to an unlatched state and can also stop the door closing operation. In other words, a "mechanism for stopping the door closing operation by the driving force of the motor (actuator)" can be added to the door lock device 20. Therefore, the user can switch the state of the latch mechanism 21 and stop the door closing operation by operating the unlatch switch 17, which is an electrical switch (i.e., without manually operating the door handle).

[0078] Furthermore, according to this embodiment, the door closing operation can be stopped by the driving force of the motor 41 that switches the state of the latch mechanism 21. Therefore, a separate motor (a motor separate from the motor 41 that switches the state of the latch mechanism 21) for moving the cancel lever 71 to the cancel position is not required. Furthermore, since the cancel lever 71 is moved from the initial position to the cancel position by the movement of the block lift lever 36 that moves the block lever 35, it is not necessary to add a member for transmitting the driving force of the motor 41 to the cancel lever 71 (a member for transmitting the driving force of the motor 41 to the block lift lever 36 and a member other than the block lift lever 36). Therefore, a "mechanism for stopping the door closing operation by the driving force of the motor 41 (actuator)" can be added to the door lock device 20 without increasing the number of parts and size of the door lock device 20.

[0079] Moreover, according to this embodiment, the block lift lever 36 directly abuts against the cancel lever 71 to move the cancel lever 71 to the cancel position. With this configuration, a member (a member arranged across the block lift lever 36 and the cancel lever 71) for transmitting the movement of the block lift lever 36 to the cancel lever 71 is not necessary. Therefore, the number of parts of the door lock device 20 and the size of the door lock device 20 are not increased. Furthermore, compared to a configuration in which the door lock device 20 does not have a "mechanism for canceling the door closing operation by the driving force of the motor 41", the movement of the block lift lever 36 can be transmitted to the cancel lever 71 only by providing the second engagement portion 362 on the block lift lever 36 and the second engagement portion 713 on the cancel lever 71 (i.e., only by partially changing the shapes of the block lift lever 36 and the cancel lever 71). Therefore, it is not necessary to change the arrangement of each member constituting the door lock device 20. Furthermore, it is not necessary to change the shapes of members other than the block lift lever 36 and the cancel lever 71. Therefore, a mechanism for stopping the door closing operation by the driving force of the motor 41 can be easily added to the door lock device 20.

[0080] Furthermore, according to the door lock device 20 of this embodiment, the open lever 51 moves from the initial position to the operating position, thereby moving the cancel lever 71 from the initial position to the cancel position. In this case, the open lever 51 and the cancel lever 71 do not interfere with the block lift lever 36. Therefore, the cancel lever 71 can be moved to the cancel position even by a manual door opening operation. Therefore, the door closing operation can be stopped by either the driving force of the motor 41 by the user's operation of the unlatch switch 17 or the manual door opening operation of the door handle by the user.

[0081] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. The present invention can be modified without departing from the spirit of the invention, and such modifications are also included in the technical scope of the present invention.

[0082] For example, in the above embodiment, the latch mechanism 21 has the block lift lever 36, and the cancel lever 71 engages with the block lift lever 36, but the present invention is not limited to such a configuration. In short, it is sufficient that the door lock device 20 has a member that moves to switch the latch mechanism 21 between the latched state and the unlatched state, and the cancel lever 71 engages with this member. In other words, in the above embodiment, an example is shown in which the latch mechanism 21 is a so-called double pole type, but the configuration of the latch mechanism 21 is not limited.

[0083] The door closer device 18 may be connected to the door lock device 20 by the close cable 81 and the cancel cable 82, and may be configured so that the close cable 81 can be pulled by the driving force of the actuator, and the action of pulling the close cable 81 can be stopped and the tension of the close cable 81 can be removed by pulling the cancel cable 82 from the outside. For example, the door closer device 18 may include an actuator, a power transmission mechanism that transmits the driving force of the actuator to the close cable 81, and a power transmission interruption mechanism that receives the tension of the cancel cable 82 and interrupts the transmission of power from the power transmission mechanism to the close cable 81. According to such a door closer device, when the cancel cable 82 is pulled, the power transmission from the actuator to the close cable 81 is interrupted, the action of pulling the close cable 81 is stopped, and the tension of the close cable 81 is removed. However, the configuration of the door closer device 18 is not limited to the above example. [Explanation of symbols]
