However, in the above-described door lock device, it may not be appropriate to start normal rotation of the motor when it is detected that the door is in a half-latched state (ajar state). That is, in a door lock device that includes a gear mechanism that transmits power from the motor to the latch and a cancel mechanism that cancels the transmission of power from the motor to the latch when the door handle is operated, when the door handle is operated, Transmission of power from the motor to the latch is cut off. Therefore, when the motor starts to be driven, the gear mechanism is rotated in a free state, and as a result, the gear mechanism generates an abnormal noise due to tooth rattling, which may give an uncomfortable feeling to the operator.

The door lock device of the present invention includes a gear mechanism that transmits power from the motor to the latch, and a cancel mechanism that cancels the transmission of power from the motor to the latch by operating an operating handle. The main purpose is to suppress the generation of abnormal noise when

The door lock device of the present invention employs the following means to achieve the above-mentioned main purpose.

The door lock device of the present invention includes:
A door lock device that holds a door on a vehicle body,
a latch that is movable from a full latch position that engages with a striker to hold the door in a fully closed state, through a half latch position that corresponds to a half-door state, to an unlatch position that releases the striker;
a motor that outputs power to the latch via a gear mechanism to move the latch to the full latch position;
an operation handle operated by an operator;
a canceling mechanism that is activated by operation of the operating handle and cancels transmission of power from the motor to the latch;
an operation detection device that detects that the operation handle is being operated;
It is determined whether the door is in the ajar state, and when it is determined that the door is in the ajar state, if the operation detection device does not detect that the operation handle is being operated, the a control device that drives the motor so that the door transitions from the ajar state to the fully closed state, and does not drive the motor if the operation detection device detects that the operating handle is being operated; ,
The main point is to have the following.

The door lock device of the present invention includes a latch that is movable from a full latch position that engages with the striker and holds the door in a fully closed state, to a half latch position that corresponds to a half-door state, and then to an unlatch position that releases the striker; It includes a motor that outputs power to the latch side via a gear mechanism to move the latch to the fully latched position, and a cancel mechanism that is activated by operating the operating handle and cancels the transmission of power from the motor to the latch. Further, the door lock device includes an operation detection device that detects an operation of the operation handle, and a control device. When the door is in the ajar state, if it is not detected that the operating handle is being operated, the control device drives the motor so that the door transitions from the ajar state to the fully closed state, and the operating handle is operated. If it is detected that it is inside, the motor will not be driven. In a door lock device equipped with a gear mechanism and a cancel mechanism, when the operating handle is operated, the gear mechanism becomes free, so if the motor is driven in this state, problems may occur due to tooth striking in the gear mechanism. A sound is produced. In the door lock device of the present invention, since the motor is not driven while the operation handle is being operated, the generation of the above-mentioned abnormal noise can be avoided.

In the door lock device of the present invention, when the control device determines that the door is in the ajar state, if the operation detection device detects that the operation handle is being operated, the control device The driving of the motor may be started after waiting until it is no longer detected that the handle is being operated. By waiting until the motor is ready to transmit power to the latch and then starting driving the motor, the door can be more reliably moved to the fully closed state.

Furthermore, in the door lock device of the present invention, the gear mechanism includes a first rotating element that is an input shaft into which power from the motor is input, a second rotating element that is an output shaft, and a third rotating element. , a planetary gear mechanism that decelerates the power input to the first rotating element and outputs it to the second rotating element while restricting rotation of the third rotating element, and when the operating handle is being operated; The rotation control member may also include a rotation restriction member that restricts rotation of the third rotation element and releases restriction on rotation of the third rotation element when the operation handle is not being operated.

As shown in FIG. 1, the door lock device 10 of this embodiment is mounted on a door 5 of a vehicle 1 and holds the door 5 in an opening of a vehicle body 2. This door lock device 10 includes a lower lock device 20 (first lock device), an upper lock device 30 (second lock device), a closer device 40, a release device 50, and a control device 60.

As shown in FIG. 2, FIG. 3, or FIG. 4, the lower lock device 20 and the upper lock device 30 are engageable with strikers 6 and 7 fixed to the lower part of the opening of the vehicle body 2 and the upper part of the opening, respectively. The engagement of the latches 21 and 31 restricts the rotation of the latches 21 and 31, and the door 5 is placed in an ajar state (also referred to as a "half latch state") or a fully closed state (a "full latch state"). poles 22, 32 that are held on the poles (also referred to as

On the outer periphery of the latches 21, 31, there are half engaging parts 212, 312 that engage with the pawls 22, 32 in the half latch position, and full engaging parts 213, 313 that engage with the pawls 22, 32 in the full latch position. is formed. Further, a pressed portion 214 is formed on the outer periphery of the latch 21 and protrudes outward at a position spaced apart from the half-engaging portion 212 and the full-engaging portion 213. A tensile portion 314 that projects outward is formed at a position spaced apart from the full engagement portion 312 and the full engagement portion 313. The latches 21 and 31 are urged counterclockwise (unlatch direction DU) in FIGS. 3 and 4 around the rotation shafts 211 and 311 by springs (not shown).

The pawls 22, 32 have engaging parts 222, 322 extending from the rotation shafts 221, 321 so as to be able to engage with the half engaging parts 212, 312 and the full engaging parts 213, 313 of the latches 21, 31. and pressed portions 223, 323 that protrude in parallel to the rotation shafts 221, 321 at positions spaced apart from the rotation shafts 221, 321 and the engaging portions 222, 322. Further, the pawls 22 and 32 are biased clockwise in FIGS. 3 and 4 around the rotation shafts 221 and 321 by springs (not shown).

The closer device 40 transmits power from the closer motor 41 to the lower lock device 20 (latch 21) and the upper lock device 30 (latch 31) to change the door 5 from a half-door state (half-latch state) to a fully closed state (full-latch state). state). As shown in FIG. 2, this closer device 40 includes, in addition to a closer motor 41, a reduction gear mechanism 42, a pinion gear 43, a latch close lever 44, and an upper close cable 45.

The reduction gear mechanism 42 reduces the power from the closer motor 41 and transmits it to the pinion gear 43. As shown in FIG. 5, this reduction gear mechanism 42 is a single pinion type having a sun gear 421s (first rotational element), a ring gear 421r (second rotational element), and a carrier 421c (third rotational element) as rotational elements. It includes a planetary gear mechanism 421 and a rotation restriction member 422 that engages with a ring gear 421r to restrict rotation of the ring gear 421r. A rotating shaft of the closer motor 41 is connected to the sun gear 421s via a worm reducer (not shown), and a pinion gear 43 is connected to the carrier 421c so as to be integrally rotatable. Thereby, the reduction gear mechanism 42 functions as a reduction gear that reduces the power from the closer motor 41 that is input to the sun gear 421s and outputs it to the pinion gear 43 that rotates integrally with the carrier 421c.

As shown in FIG. 2, the latch close lever 44 includes a sector gear 442 that is formed in a fan shape with the rotation axis 441 as the center of curvature and meshes with the pinion gear 43, and a sector gear 442 that extends on the opposite side of the rotation axis 441 from the sector gear 442. It includes an extended pressing portion 443 and a tension portion 444 formed at a position spaced apart from the sector gear 442 and the pressing portion 443. In the pressing part 443, the sector gear 442 is driven by the power transmitted from the closer motor 41 to the pinion gear 43 via the reduction gear mechanism 42, and the latch close lever 44 is rotated to the rotation end in the clockwise direction in FIG. As a result, the pressed portion 214 of the latch 21 is pressed, and the latch 21 is rotated clockwise (full latch direction DL) in FIG. Thereby, the striker 6 can be retracted by the latch 21 to bring the lower lock device 20 into the fully latched state.

As shown in FIG. 2, one end of an upper close cable 45 is fixed to the tension portion 444 of the latch close lever 44. As shown in FIG. The other end of the upper close cable 45 is engaged with the tensioned portion 314 of the latch 31, as shown in FIG. When the latch close lever 44 rotates to the rotation end in the clockwise direction in FIG. 2, the tensioning portion 444 pulls the upper close cable 45 and moves the latch 31 clockwise in FIG. 4 (full latch direction DL). Rotate. Thereby, the striker 7 can be retracted by the latch 31 to bring the upper lock device 30 into the fully latched state. That is, by rotating the latch close lever 44 using the power from the closer motor 41, both the lower lock device 20 and the upper lock device 30 can be brought into the fully latched state, and the door 5 can be brought into the fully closed state.

The release device 50 transmits the operating force of the inside door handle 5i and the outside door handle 5o to the poles 22, 32 to release the fully latched state of the latch 21 of the lower lock device 20 and the latch 31 of the upper lock device 30. . The release device 50 includes a link lever 51, a lower lock open cable 52, a lower lock open lever 53, an upper lock open cable 54, an upper lock open lever 55, and a cancel cable 56.

The link lever 51 is connected to the inside door handle 5i and the outside door handle 5o via power transmission members, respectively, and rotates in conjunction with the operation of the inside door handle 5i or the outside door handle 5o. One end of a lower lock open cable 52 and one end of an upper lock open cable 54 are connected to the outer periphery of the linkage lever 51. As shown in FIG. 2, a lower lock open lever 53 is connected to the other end of the lower lock open cable 52, and an upper lock open lever 55 is connected to the other end of the upper lock open cable 54, as shown in FIG. is connected.

As shown in FIG. 2, the lower lock open lever 53 includes a tensioned part 532 extending from a rotation shaft 531 and a pressing part 533 extending from the rotation shaft 531 so as to be spaced apart from the tensioned part 532. Be prepared. The other end of the lower lock open cable 52 is fixed to the tensioned part 532. When the linking lever 51 is rotated by operating the inside door handle 5i or the outside door handle 5o, the lower lock open cable 52 is pulled, and the lower lock open lever 53 is rotated counterclockwise in FIG. rotate in the direction. The pressing portion 533 presses the pressed portion 223 of the pawl 22 by rotation of the lower lock open lever 53, and rotates the pawl 22 counterclockwise in FIG. 3. As a result, the engagement between the pawl 22 and the latch 21 is released, and the latch 21 is rotated counterclockwise (unlatch direction DU) in FIG. 3 by the biasing force of the spring. As a result, the lower lock device 20 becomes in an unlatched state (unfitted state).

As shown in FIG. 4, the upper lock open lever 55 includes a tensioned part 552 extending from a rotation shaft 551 and a pressing part 553 extending from the rotation shaft 551 away from the tensioned part 552. Be prepared. The other end of the upper lock open cable 54 is fixed to the tensioned part 552. When the linking lever 51 is rotated by operating the inside door handle 5i or the outside door handle 5o, the upper lock open cable 54 is pulled, and the upper lock open lever 55 is rotated clockwise in FIG. Rotate to. The pressing portion 553 presses the pressed portion 323 of the pawl 32 by rotation of the upper lock open lever 55, and rotates the pawl 32 counterclockwise in FIG. 4. As a result, the engagement between the pawl 32 and the latch 31 is released, and the latch 31 is rotated counterclockwise (unlatch direction DU) in FIG. 4 by the biasing force of the spring. As a result, the upper lock device 30 is in an unlatched state (unfitted state). That is, when the operator operates the inside door handle 5i or the outside door handle 5o and rotates the lower lock open lever 53 and the upper lock open lever 55, both the lower lock device 20 and the upper lock device 30 are brought into the unlatched state. As a result, the door 5 can be left open.

Further, one end of a cancel cable 56 is connected to the outer peripheral portion of the linkage lever 51. The other end of the cancel cable 56 is connected to a rotation regulating member 422 of the reduction gear mechanism 42, as shown in FIG. When the door handle (inside door handle 5i or outside door handle 5o) is operated, the cancellation cable 56 is pulled by the operating force transmitted from the door handle to the linking lever 51, and the rotation regulating member 422 and the planetary gear mechanism 421 are connected to each other. The engagement with ring gear 421r is released. As a result, the ring gear 421r becomes freely rotatable, and power transmission between the sun gear 421s and the carrier 421c of the reduction gear mechanism 42, that is, between the closer motor 41 and the pinion gear 43 is cut off. Therefore, if the operator operates the door handle while the closer device 40 is in the middle of transitioning from the half-latched state to the full-latched state, the transition to the full-latched state is canceled, and the operator immediately opens the door 5. It becomes possible to do so.

The control device 60 is configured as a microprocessor centered around a CPU, and includes a ROM, a RAM, and an input/output port in addition to the CPU. Detection signals from various switches are input to the control device 60 via input ports, and control signals to the closer motor 41 are output from the control device 60 via an output port. As shown in FIG. 6, the various switches include a latch switch 70 for detecting the state of the latch 21 of the lower lock device 20, a pole switch 75 for detecting the state of the pole 22 of the lower lock device 20, and an upper lock device. A latch switch 80 for detecting the state of the latch 31 of the upper lock device 30, a pole switch 85 for detecting the state of the pole 32 of the upper lock device 30, and an origin for detecting the origin (original position) of the latch close lever 44. Examples include a switch 76 and a handle switch 77 for detecting operation of a door handle (inside door handle 5i or outside door handle 5o).

In this embodiment, the latch switches 70 and 80 include three electrodes (first electrodes 71 and 81, second electrodes 72 and 82, and third electrodes 73 and 83) arranged in the circumferential direction, and latches 21 and 31. It is configured as a rotary switch having rotating contacts 74 and 84 that interlock (rotate together). The first electrodes 71 and 81 are connected to the input port of the control device 60 via the half-latch switch signal line 61, and the second electrodes 72 and 82 are connected to the input port of the control device 60 via the full-latch switch signal line 62. connected to. Further, the third electrodes 73 and 83 are connected to the ground line 69. The rotating contacts 74, 84 conduct (turn on) the first electrodes 71, 81 and the third electrodes 73, 83 until the latches 21, 31 reach the half-latched position from the unlatched position, and after the latches reach the half-latched position. disconnects (turns off) the first electrodes 71, 81 and the third electrodes 73, 83. Thereby, the first electrodes 71, 81, the third electrodes 73, 83, and the rotating contacts 74, 84 constitute a half latch switch for detecting the half latch position of the latches 21, 31. In the half-latch switch, first electrodes 71 and 81 are each connected to a common half-latch switch signal line 61. Therefore, the half-latch switch signal line 61 is turned off when both the latch 21 of the lower lock device 20 and the latch 31 of the upper lock device 30 reach the half-latch position. Further, the rotating contacts 74, 84 conduct (turn on) the second electrodes 72, 82 and the third electrodes 73, 83 until the latches 21, 31 reach the full latched position from the unlatched position, and after the latches 21, 31 reach the full latched position, disconnects (turns off) the second electrodes 72, 82 and the third electrodes 73, 83. Thereby, the second electrodes 72, 82, the third electrodes 73, 83, and the rotating contacts 74, 84 constitute a full latch switch for detecting the full latch position of the latches 21, 31. In the full latch switch, second electrodes 72 and 82 are each connected to a common full latch switch signal line 62. Therefore, the full latch switch signal line 62 is turned off when both the latch 21 of the lower lock device 20 and the latch 31 of the upper lock device 30 reach the full latch position.

The pole switches 75 and 85 are contact switches provided in the movable range of the poles 22 and 32. One terminal of the pole switches 75 and 85 is connected to an input port of the control device 60 via a pole switch signal line 63. The other terminals of the pole switches 75 and 85 are connected to the ground line 69. In the pole switches 75 and 85, when the poles 22 and 32 are in the non-engaged position, the poles 22 and 32 are in contact and conductive (turned on), and when the poles 22 and 32 are in the engaged position (the poles 22 and 32 are in the latch 21, When the pawls 22, 32 are in the position of engaging with the half engaging portions 212, 312 or the full engaging portions 213, 313 of 31, the poles 22, 32 are separated and shut off (off). The pole switches 75 and 85 are each connected to a common pole switch signal line 63. Therefore, the pole switch signal line 63 is turned off when the pole 22 of the lower lock device 20 and the pole 32 of the upper lock device 30 are both in the engaged position.

The origin switch 76 is, for example, a contact switch provided in the movable range of the latch close lever 44. One terminal of the origin switch 76 is connected to an input port of the control device 60 via the origin switch signal line 64. The other terminal of the origin switch 76 is connected to the ground line 69. The origin switch 76 is turned on when the latch close lever 44 comes in contact with the latch close lever 44 when it is near the origin, and is disconnected when the latch close lever 44 is not near the origin and is shut off. (off).

The handle switch 77 is, for example, a contact switch provided in the movable range of the link lever 51. One terminal of the handle switch 77 is connected to the input port of the control device 60 via the handle switch signal line 65. The other terminal of the handle switch 77 is connected to the ground line 69. In the handle switch 77, when the door handle (inside door handle 5i or outside door handle 5o) is not operated, the linking lever 51 is separated and shut off (off), and when the door handle is being operated, the linking lever 51 is turned off. Continuity (turns on) occurs upon contact.

FIG. 7 is a time chart showing the state of each switch of the lower lock device 20, the state of each switch of the upper lock device 30, and how the signals input to the control device change over time. In the figure, "unfitted" in the latch fitted state is a state in which the latches 21 and 31 are in the section from the unlatched position to a position past the half-latched position, and the poles 22 and 32 are in the disengaged position. shows. "Full latch" indicates a state in which the latches 21 and 31 are in a position past the full latch position and the pawls 22 and 32 are in the engaged position. "Half latch" indicates an intermediate state between "unmated" and "full latch."

The door lock device 10 locks the door 5 in a fully closed state by rotating the latches 21 and 31 of the two lock devices (lower lock device 20 and upper lock device 30) in the full latch direction. When the latches 21 and 31 rotate in the full-latch direction and reach the half-latch position, the half-latch switches of the latch switches 70 and 80 are turned from on to off. In FIG. 7, the time ta1 at which the half latch switch of the latch switch 70 is turned off is later than the time tb1 at which the half latch switch of the latch switch 80 is turned off, so the half latch switch signal line 61 is turned off at time ta1. , the control device 60 recognizes that both latches 21 and 31 have reached the half-latched position.

When the latches 21, 31 further rotate in the full latching direction and the pawls 22, 32 engage with the half engaging portions 212, 312 of the latches 21, 31, the pawl switches 75, 85 turn from on to off. In FIG. 7, since the time ta2 at which the pole switch 75 is turned off is later than the time tb2 at which the pole switch 85 is turned off, the pole switch signal line 63 is turned off at time ta2, and the control device 60 It is recognized that both have reached the engaged position.

When the latches 21 and 31 further rotate in the full-latch direction and reach the full-latch position, the full-latch switches of the latch switches 70 and 80 are turned from on to off. In FIG. 7, the time ta3 at which the full latch switch of the latch switch 70 is turned off is later than the time tb3 at which the full latch switch of the latch switch 80 is turned off, so the full latch switch signal line 62 is turned off at time ta3. , the control device 60 recognizes that both latches 21 and 31 have reached the full latched position.

When the latches 21 and 31 further rotate in the full-latch direction and the pawls 22 and 32 engage with the full engagement portions 213 and 313 of the latches 21 and 31, the pawl switches 75 and 85 turn from on to off. In FIG. 7, since the time ta4 at which the pole switch 75 is turned off is later than the time tb4 at which the pole switch 85 is turned off, the pole switch signal line 63 is turned off at time ta4, and the control device 60 It is recognized that both have reached the engaged position.

Next, the operation of the door lock device 10 of this embodiment configured in this manner will be described. In particular, the operation when the door 5 is moved from the ajar state (half latch state) to the fully closed state (full latch state) will be described. FIG. 8 is a flowchart showing an example of a control routine executed by the CPU of the control device 60.

When the control routine is executed, the CPU of the control device 60 first inputs the state of the half latch switch signal line 61 and the state of the pole switch signal line 63 (step S100), and the lower lock device 20 and the upper lock device 30 are activated. It is determined whether both are in a half-latch state (the half-latch signal line 61 is off and the pole switch signal line 63 is off), that is, the door 5 is in a half-door state (step S110). If it is determined that the door 5 is not in the ajar state, the process returns to step S100 and repeats the process. On the other hand, if it is determined that the door 5 is in the ajar state, the state of the handle switch signal line 65 is input (step S120), and the door handle (inside door handle 5i or outside door handle 5o) is being operated ( It is determined whether the handle switch signal line 65 is on) (step S130). If it is determined that the door handle is not being operated, a closing operation is started to control the closer motor 41 so that the door 5 shifts from the ajar state to the fully closed state (step S140), and this routine ends. On the other hand, if it is determined that the door handle is being operated, the process returns to step S100. That is, if it is determined that the door handle is being operated, the closing operation is not performed even if the door 5 is in the ajar state. As described above, when the door handle is operated, the ring gear 421r of the planetary gear mechanism 421 of the reduction gear mechanism 42 becomes freely rotatable, and the transmission of power from the closer motor 41 to the pinion gear 43 is interrupted. If the closer motor 41 is driven in this state, the planetary gear mechanism 421 may generate an abnormal noise due to tooth striking, which may give the user a sense of discomfort. In this embodiment, when the door handle is being operated, the closer motor 41 is not driven even if the door 5 is in the ajar state, which prevents abnormal noise from occurring in the reduction gear mechanism 42 (planetary gear mechanism 421). can be avoided. If it is determined in step S130 that the door handle is being operated, the process returns to step S100 and the process is repeated, and in the process of repeating the process, it is determined that the door is in the ajar state in step S110, and if the door handle is not being operated in step S130. When the determination is made, a closing operation is started (step S140), and this routine is ended. That is, if the door handle is being operated while the door 5 is in the ajar state, the closing operation is started after waiting until the door handle is no longer being operated. Thereby, the door 5 can be moved to the fully closed state more reliably.

FIG. 9 is a time chart showing the operation of the closer device when the door is ajar and the door handle is not operated. As shown in FIG. 9, in the control device 60, both the latches 21 and 31 reach the half-latch position and the state of the half-latch switch signal line 61 is turned off (time t11), and the poles 22 and 32 switch to the latches 21 and 31. When a predetermined time TB has elapsed (time t13) after the pole switch signal line 63 is engaged with the half-engaging parts 212 and 312 and turned off (time t12), the closer motor 41 is driven in the forward direction (latched). (driving in the direction of rotating the close lever 44 toward the full latch side) is started. Note that the normal rotation drive may be started when a predetermined time TA has elapsed since the state of the half-latch switch signal line 61 was turned off (time t11). Next, the control device 60 causes the latches 21 and 31 to both reach the full latch position and the state of the full latch switch signal line 62 to turn off (time 14), and the poles 22 and 32 to the full engagement portions 213 of the latches 21 and 31. , 313 and the state of the pole switch signal line 63 is turned off again (time t15), the normal rotation drive of the closer motor 41 is stopped. Subsequently, when a predetermined time TD has elapsed since stopping the forward rotation of the closer motor 41 (time t16), the control device 60 causes the closer motor 41 to be reversely driven (in the direction of returning the latch close lever 44 to the origin). drive). Note that the reverse drive may be started when a predetermined time TC has elapsed since the state of the full latch switch signal line 62 was turned off (time t14). Then, when the state of the origin switch signal line 64 changes from on to off, the control device 60 stops the reverse drive of the closer motor 41. Note that the reverse drive may be stopped when a predetermined time TE has elapsed since the start of the reverse drive (time t16).

FIG. 10 is a time chart showing the operation of the closer device when the door handle is operated with the door ajar. The control device 60 controls the door handle (inside door) even if a predetermined time TB has elapsed since the state of the half latch switch signal line 61 was turned off and the state of the pole switch signal line 63 was turned off (time t13). When the handle 5i or the outside door handle 5o is being operated and the handle switch signal line 65 is on, the closer motor 41 does not start to rotate forward. When the door handle is no longer being operated and the state of the handle switch signal line 65 changes from on to off (time t21), the control device 60 starts driving the closer motor 41 in normal rotation. Next, the control device 60 controls the closer motor 41 when the full latch switch signal line 62 is turned off (time t22) and the pole switch signal line 63 is turned off again (time t23). Stop normal rotation drive. Then, when a predetermined time TD has elapsed after stopping the forward rotation drive of the closer motor 41 (time t24), the control device 60 starts reverse drive of the closer motor 41, and changes the state of the origin switch signal line 64. When turned off (time t25), the reverse rotation of the closer motor 41 is stopped.

In the door lock device 10 of the present embodiment described above, when the door 5 is in the ajar state, if the door handle (inside door handle 5i or outside door handle 5o) is not being operated, the door 5 is in the ajar state. The closer motor 41 is driven so as to shift from the door to the fully closed state, and the closer motor 41 is not driven if the door handle is being operated. This prevents rattling noise (abnormal noise) caused by the closer motor 41 being driven when the reduction gear mechanism 42 (ring gear 421r of the planetary gear mechanism 421) is in a free state due to the operation of the door handle. can be avoided. Moreover, if the closer motor 41 is not driven because the door handle is being operated, the closer motor 41 is started to be driven after waiting until the door handle is no longer being operated, thereby ensuring that the door 5 is fully closed. can be moved to.

In the embodiment, the strikers 6 and 7 are provided at the opening of the vehicle body 2, and the door lock device 10 is provided at the door 5, but the present invention is not limited to this, and the door lock device may be provided at the opening of the vehicle body 2. , the door 5 may be provided with a striker.

In the embodiment, the door lock device 10 locks the door 5 in the fully closed state by engaging the two latches 21 and 31 with the two strikers 6 and 7, but The door 5 may be locked by engaging the latch.
