Description

[Technical field]

[0001] The present invention relates to a remote control device. [Background technology]

[0002] Patent Document 1 describes a vehicle including a vehicle body having a door opening and a sliding door for opening and closing the door opening. The vehicle body includes a first striker and a second striker. The sliding door includes a first latch mechanism and a second latch mechanism, a remote control device, a door lock drive unit, and a plurality of cables.

[0003] The first latch mechanism is configured to be able to transition from one of a fully latched state in which the first striker can be engaged with the first striker and an unlatched state in which the first striker cannot be engaged with the first striker to the other state. Similarly, the second latch mechanism is configured to be able to transition from one of a fully latched state in which the second striker can be engaged with the second striker and an unlatched state in which the second striker cannot be engaged with the second striker to the other state. By transitioning to the fully latched state, the first latch mechanism and the second latch mechanism restrain the sliding door disposed in the fully closed position to the vehicle body.

[0004] The remote control device is connected to the door lock drive unit via a release cable. The remote control device is also connected to the first latch mechanism via a first open cable and to the second latch mechanism via a second open cable. The remote control device relays power between the door lock drive unit and the first and second latch mechanisms.

[0005] The door lock drive unit performs a release operation to release the sliding door from its restraint on the vehicle body. In the release operation, the door lock drive unit pulls the release cable. The remote control device then pulls the first open cable and the second open cable. As a result, the first latch mechanism transitions to an unlatched state, and the second latch mechanism transitions to an unlatched state. In this way, the sliding door is released from its restraint on the vehicle body. The door lock drive unit then releases the pull on the release cable. In this case, the remote control device also releases the pull on the first open cable and the second open cable.

[0006] However, if the door lock drive unit malfunctions while pulling the release cable, the first latch mechanism and the second latch mechanism cannot transition from the unlatched state to another state. More specifically, the first latch mechanism and the second latch mechanism cannot restrain the sliding door to the vehicle body in the fully closed position. In this regard, the above remote control device has a cancel mechanism that cuts off the power transmission path between the door lock drive unit and the first and second latch mechanisms based on manual operation by the user. Therefore, in the above case, by activating the cancel mechanism, the first and second latch mechanisms can transition to the fully latched state. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2020-204225 A Summary of the Invention [Problem to be solved by the invention]

[0008] In the vehicle as described above, the door lock drive unit may be configured to perform a closing operation that transitions the first latch mechanism and the second latch mechanism to a fully latched state via a remote control device. In this case, the remote control device may have a cancel mechanism that interrupts a power transmission path between the door lock drive unit and the first and second latch mechanisms during the closing operation in case the door lock drive unit malfunctions during the closing operation. However, it is preferable that such a cancel mechanism be easy for a user to operate. [Means for solving the problem]

[0009] A remote control device that solves the above problem is applied to a door that opens and closes a door opening of a vehicle body having a first striker and a second striker, the door having a first door lock device that can be shifted to a fully latched state in which it can be engaged with the first striker and an unlatched state in which it cannot be engaged with the first striker, and a second door lock device that can be shifted to a fully latched state in which it can be engaged with the second striker and an unlatched state in which it cannot be engaged with the second striker, the remote control device being applied to a door that has a first striker and a second striker, the door lock device including a close passive lever connected to the first door lock device via a first close cable and connected to the second door lock device via a second close cable, a close active lever that drives the close passive lever, a release passive lever connected to the first door lock device via a first open cable and connected to the second door lock device via a second open cable, a release active lever that drives the release passive lever, and an emergency lever that drives the close passive lever and the release passive lever, the second door lock device is transitioned to an unlatched state when the open cable is pulled and to a fully latched state when the first close cable is pulled, the second door lock device is transitioned to an unlatched state when the second open cable is pulled and to a fully latched state when the second close cable is pulled, the close active lever causes the close passive lever to pull the first close cable and the second close cable when it rotates in a closing direction and releases the pulling of the first close cable and the second close cable by the close passive lever when it rotates in a direction opposite to the closing direction, the release active lever causes the release passive lever to pull the first open cable and the second open cable when it rotates in a release direction and releases the pulling of the first open cable and the second open cable by the release passive lever when it rotates in a direction opposite to the release direction, and the emergency lever is rotated in a forced release direction,By displacing the close passive lever relative to the close active lever, the pulling of the first close cable and the second close cable by the close passive lever is released, and by displacing the release passive lever relative to the release active lever, the pulling of the first open cable and the second open cable by the release passive lever is released. Effect of the Invention

[0010] The remote control device can make it easy for the user to understand the operation for releasing the pulling of the first closed cable and the second closed cable and the operation for releasing the pulling of the first open cable and the second open cable.

[0012] An embodiment of a vehicle 10 equipped with a remote control device 100 will now be described. As shown in FIG. 1, a vehicle 10 includes a vehicle body 20, a door support mechanism 30, a front door 40F, a rear door 40R, and a door control device 300.

[0013] <Vehicle 20> The vehicle body 20 has a door opening 21 that opens to a side surface. The vehicle body 20 also has a plurality of strikers 22 arranged along the edge of the door opening 21.

[0014] The door opening 21 has a front opening 21F which is a front portion of the door opening 21, and a rear opening 21R which is a rear portion of the door opening 21. In this embodiment, there is no pillar between the front opening 21F and the rear opening 21R. In other embodiments, the vehicle body 20 may have a pillar that divides the front opening 21F and the rear opening 21R.

[0015] The plurality of strikers 22 include a front striker 23F, a rear striker 23R, two upper strikers 24F, 24R, and two lower strikers 25F, 25R.

[0016] The front striker 23F is located at the front end of the door opening 21. The rear striker 23R is located at the rear end of the door opening 21. The two upper strikers 24F, 24R are located at the upper end of the door opening 21 and at the center of the door opening 21 in the front-rear direction. The two upper strikers 24F, 24R are lined up in the front-rear direction. The two lower strikers 25F, 25R are located at the lower end of the door opening 21 and at the center of the door opening 21 in the front-rear direction. The two lower strikers 25F, 25R are lined up in the front-rear direction. Of the multiple strikers 22, the front striker 23F, the upper striker 24F, and the lower striker 25F correspond to a connecting portion with the front door 40F of the vehicle body 20. On the other hand, of the multiple strikers 22, the rear striker 23R, the upper striker 24R, and the lower striker 25R correspond to a connecting portion with the rear door 40R of the vehicle body 20. The Upper Striker 24F corresponds to the "First Striker" and the Lower Striker 25F corresponds to the "Second Striker".

[0017] <Door support mechanism 30> The door support mechanism 30 has two front links 31F that connect the vehicle body 20 to the front door 40F, and two rear links 31R that connect the vehicle body 20 to the rear door 40R.

[0018] The two front links 31F are positioned offset in the vertical direction. The front link 31F has two hinges 32F, 33F whose axial direction is the vertical direction. The two hinges 32F, 33F are positioned at both ends of the front link 31F in the longitudinal direction. The hinge 32F is fixed near the front end of the door opening 21 in the vehicle body 20, and the hinge 33F is fixed to the front door 40F. In this way, the vehicle body 20, the two front links 31F, and the front door 40F constitute a link mechanism with the vehicle body 20 as a fixed link.

[0019] The two rear links 31R are positioned offset in the vertical direction. The rear link 31R has two hinges 32R, 33R whose axial direction is the vertical direction. The two hinges 32R, 33R are positioned at both ends in the longitudinal direction of the rear link 31R. The hinge 32R is fixed near the rear end of the door opening 21 in the vehicle body 20, and the hinge 33R is fixed to the rear door 40R. In this way, the vehicle body 20, the two rear links 31R, and the rear door 40R form a link mechanism with the vehicle body 20 as a fixed link.

[0020] As described above, the front door 40F swings between a fully closed position where the front opening 21F is fully closed and a fully open position where the front opening 21F is fully opened, drawing an arc-shaped trajectory. On the other hand, the rear door 40R swings between a fully closed position where the rear opening 21R is fully closed and a fully open position where the rear opening 21R is fully opened, drawing an arc-shaped trajectory and a linear trajectory. When the front door 40F and the rear door 40R are simultaneously opened, the front door 40F and the rear door 40R move in directions away from each other. On the other hand, when the front door 40F and the rear door 40R are simultaneously closed, the front door 40F and the rear door 40R move in directions approaching each other. In other words, the opening direction of the front door 40F is opposite to the opening direction of the rear door 40R, and the closing direction of the front door 40F is opposite to the closing direction of the rear door 40R.

[0021] <Front door 40F> As shown in Fig. 1, the front door 40F includes an upper locking device 50, a lower locking device 60, a front locking device 70, an operation unit 80, a door driving unit 90, a remote control device 100, and a plurality of cables C1 to C7. The front door 40F corresponds to a "door." The rear door 40R has the same configuration as the front door 40F, and therefore the following description will be omitted.

[0022] <Upper locking device 50 and lower locking device 60> As shown in Fig. 1, the upper locking device 50 is provided near the rear end of the front door 40F and near the top end of the front door 40F. The lower locking device 60 is provided near the rear end of the front door 40F and near the bottom end of the front door 40F. The upper locking device 50 and the lower locking device 60 have the same configuration. The upper locking device 50 corresponds to the "first door locking device" and the lower locking device 60 corresponds to the "second door locking device."

[0023] 2 and 3, the upper locking device 50 and the lower locking device 60 include a latch 51, a pole 52, an open lever 53, and a close lever 54. The upper locking device 50 and the lower locking device 60 also include a latch support shaft 55, a pole support shaft 56, an open lever support shaft 57, and a close lever support shaft 58. The upper locking device 50 and the lower locking device 60 also include a latch spring 51S, a pole spring 52S, an open lever spring 53S, and a close lever spring 54S.

[0024] As shown in Fig. 2, the latch 51 has a recess corresponding to the thickness of the striker 22. The latch 51 is rotatably supported by a latch support shaft 55. The latch 51 is biased in a first rotation direction R11 by a latch spring 51S. The pole 52 is rotatably supported by a pole support shaft 56. The pole 52 is biased in a second rotation direction R22 by a pole spring 52S. The axis of the latch support shaft 55 and the axis of the pole support shaft 56 are oriented in approximately the same direction.

[0025] 3, the open lever 53 is rotatably supported by an open lever support shaft 57. A first end of an upper open cable C1 is connected to the open lever 53 of the upper locking device 50, and a first end of a lower open cable C2 is connected to the open lever 53 of the lower locking device 60. The open lever 53 is biased in a first rotation direction R31 by an open lever spring 53S.

[0026] The close lever 54 is rotatably supported by a close lever support shaft 58. A first end of an upper close cable C3 is connected to the close lever 54 of the upper locking device 50, and a first end of a lower close cable C4 is connected to the close lever 54 of the lower locking device 60. The close lever 54 is biased in the second rotation direction R42 by a close lever spring 54S.

[0027] The axis of the open lever support shaft 57 and the axis of the close lever support shaft 58 are oriented in substantially the same direction. The axis of the open lever support shaft 57 and the axis of the close lever support shaft 58 are in a twisted positional relationship with the axis of the latch support shaft 55 and the axis of the pole support shaft 56.

[0028] <Front lock device 70> Many of the components of the front locking device 70 are similar to those of the upper locking device 50. For this reason, among the components of the front locking device 70, those components common to those of the upper locking device 50 are given the same reference numerals and will not be described.

[0029] 2 and 4, the front locking device 70 includes, as components common to the upper locking device 50, a latch 51, a pole 52, an open lever 53, a latch support shaft 55, a pole support shaft 56, and an open lever support shaft 57. The front locking device 70 also includes a latch spring 51S, a pole spring 52S, and an open lever spring 53S. As shown in FIG. 4, the front locking device 70 includes, as components not common to the upper locking device 50, a close lever 71, a release lever 72, a close lever support shaft 73, a release lever support shaft 74, and a release lever spring 72S. The front locking device 70 also includes a first door lock drive unit 75.

[0030] The open lever 53 is rotatably supported by an open lever support shaft 57. A first end of a front open cable C5 is connected to the open lever 53. The open lever 53 is biased in a first rotation direction R31 by an open lever spring 53S. The close lever 71 is rotatably supported by a close lever support shaft 73. The release lever 72 is rotatably supported by a release lever support shaft 74. A first end of a release cable C6 is connected to the release lever 72. The release lever 72 is biased in the first rotation direction R51 by a release lever spring 72S. An axis of the open lever support shaft 57 and an axis of the close lever support shaft 73 are oriented in substantially the same direction.

[0031] <First door lock drive unit 75> The first door lock driving unit 75 drives the close lever 71 and the release lever 72. More specifically, the first door lock driving unit 75 rotates the close lever 71 in a first rotation direction R41 and a second rotation direction R42, and rotates the release lever 72 in a first rotation direction R51 and a second rotation direction R52. The first door lock driving unit 75 includes an electric motor and a transmission mechanism that transmits the power of the electric motor to the close lever 71 and the release lever 72. As an example, the transmission mechanism of the first door lock driving unit 75 may have a gear that drives only the close lever 71 when rotating in one direction from a reference position, and drives only the release lever 72 when rotating in the other direction from the reference position.

[0032] <Operation unit 80> As shown in Fig. 1, a first end of the emergency cable C7 is connected to the operation unit 80. The operation unit 80 may have any shape as long as it can pull the emergency cable C7 by being operated by a user or the like. For example, the operation unit 80 may be in the form of a lever or a button. However, the direction in which the operation unit 80 is operated, i.e., the direction in which it operates to pull the emergency cable C7, is a single direction.

[0033] <Remote control device 100> As shown in FIGS. 5 and 6, remote control device 100 includes a first remote control unit 101 having components mainly related to a release operation, and a second remote control unit 102 having components mainly related to a close operation.

[0034] <First remote control unit 101> 7 and 8, the first remote control unit 101 includes a first base 110, a release active lever 120, a release passive lever 130, an emergency lever 140, a lock lever 150, and a lock pin 160. The first remote control unit 101 also includes a lever support shaft 170, a release active lever spring 120S, a release passive lever spring 130S, and a lock lever spring 150S.

[0035] In the following description, the release active lever 120 will be referred to as the "RA lever 120," and the release passive lever 130 will be referred to as the "RP lever 130." Additionally, the release active lever spring 120S will be referred to as the "RA lever spring 120S," and the release passive lever spring 130S will be referred to as the "RP lever spring 130S."

[0036] As shown in FIG. 7, the first base 110 is plate-shaped. The first base 110 has a plurality of stoppers 111-113 for positioning a plurality of levers. The plurality of stoppers 111-113 are formed by cutting and raising a part of the first base 110. The first base 110 has a plurality of openings penetrating in the plate thickness direction. The first base 110 has a communication hole 114 as one of the plurality of openings. When viewed from the front in the plate thickness direction of the first base 110, the communication hole 114 extends in an arc shape. In the first base 110, a lever support shaft 170 is fixed at a position that is the center of the arc-shaped communication hole 114. The axis of the lever support shaft 170 extends in the plate thickness direction of the first base 110.

[0037] As shown in FIG. 7 and FIG. 8, the RA lever 120 is plate-shaped. The RA lever 120 has a base 121, a first arm 122, and a guide portion 123. The base 121 corresponds to the center of the RA lever 120. The RA lever 120 is rotatably supported by the lever support shaft 170 via the base 121. The first arm 122 extends from the base 121. A second end of the release cable C6 is connected to the tip of the first arm 122. In a front view in the plate thickness direction, the guide portion 123 extends so as to widen as it moves away from the base 121. The guide portion 123 has a guide hole 124 penetrating in the plate thickness direction. The guide hole 124 includes a first portion 125 that is a portion farther from the base 121, and a second portion 126 that is a portion closer to the base 121. In a front view in the plate thickness direction, the first portion 125 and the second portion 126 extend in an arc shape centered on the base portion 121. The circumferential length of the first portion 125 is less than the circumferential length of the second portion 126. Therefore, a first side surface 125a that defines the first portion 125 and a second side surface 126a that defines the second portion 126 are positioned offset from each other in the circumferential direction.

[0038] 7, a first end of the RA lever spring 120S is engaged with the RA lever 120, and a second end of the RA lever spring 120S is engaged with the first base 110. In this manner, the RA lever spring 120S biases the RA lever 120 in the first rotation direction R61. Therefore, the first arm 122 of the RA lever 120 is in contact with the stopper 111 of the first base 110.

[0039] As shown in FIG. 7 and FIG. 8, the RP lever 130 is plate-shaped. The RP lever 130 has a base 131, a second arm 132, a third arm 133, and a fourth arm 134. The base 131 corresponds to the center of the RP lever 130. The RP lever 130 is rotatably supported by a lever support shaft 170 via the base 131. The second arm 132, the third arm 133, and the fourth arm 134 extend in different directions from the base 131. A second end of the front open cable C5 is connected to a tip of the second arm 132. A second end of the upper open cable C1 and a second end of the lower open cable C2 are connected to a tip of the third arm 133. The fourth arm 134 has a guide groove 134a extending in the longitudinal direction of the fourth arm 134. The guide groove 134a penetrates the fourth arm 134 in the plate thickness direction.

[0040] As shown in Fig. 7, a first end of the RP lever spring 130S is engaged with the lever support shaft 170, and a second end of the RP lever spring 130S is engaged with the RP lever 130. In this way, the RP lever spring 130S biases the RP lever 130 in the first rotation direction R61. Therefore, as shown in Fig. 7, the third arm 133 of the RP lever 130 is in contact with the stopper 113 of the first base 110.

[0041] As shown in FIG. 7 and FIG. 8, the emergency lever 140 is plate-shaped. The emergency lever 140 has a base 141, a fifth arm 142, and a sixth arm 143. The base 141 corresponds to the center of the emergency lever 140. The emergency lever 140 is rotatably supported on the lever support shaft 170 via the base 141. The fifth arm 142 and the sixth arm 143 extend in different directions from the base 141. The fifth arm 142 has a first pressing portion 142a and a second pressing portion 142b. The first pressing portion 142a is located at the middle portion in the longitudinal direction of the fifth arm 142, and the second pressing portion 142b is located at the tip of the fifth arm 142. The first pressing portion 142a and the second pressing portion 142b are bent in the plate thickness direction of the fifth arm 142. However, the first pressing portion 142a extends in a direction opposite to the direction in which the second pressing portion 142b extends. As shown in Fig. 7, the second pressing portion 142b passes through the communication hole 114 of the first base 110. A second end of the emergency cable C7 is connected to the tip of the sixth arm 143.

[0042] In this embodiment, the RA lever 120, the RP lever 130, and the emergency lever 140 are stacked in the plate thickness direction of the first base 110. More specifically, the RP lever 130 is located farthest from the first base 110, and the emergency lever 140 is located closest to the first base 110. The RA lever 120 is located between the RP lever 130 and the emergency lever 140. In addition, the RA lever 120, the RP lever 130, and the emergency lever 140 are supported by a lever support shaft 170. In this respect, the rotation axis of the RA lever 120, the rotation axis of the RP lever 130, and the rotation axis of the emergency lever 140 coincide with each other.

[0043] As shown in FIG. 7 and FIG. 8, the lock lever 150 is molded from, for example, a resin material. The lock lever 150 has a link 151, a rotating shaft portion 152, and an engagement shaft portion 153. The link 151 is plate-shaped. When the link 151 is viewed from the plate thickness direction, the link 151 extends in an arc shape. The link 151 has a sliding groove 154 extending in the longitudinal direction of the link 151. The sliding groove 154 is located between the intermediate portion and the first end in the longitudinal direction of the link 151. The rotating shaft portion 152 extends from the link 151 in the plate thickness direction of the link 151. The rotating shaft portion 152 is located in the center portion in the longitudinal direction of the link 151. The lock lever 150 is supported by the first base 110 via the rotating shaft portion 152. In this way, the lock lever 150 is rotatable with respect to the first base 110. The engagement shaft portion 153 extends from the link 151 in the thickness direction of the link 151. The projection direction of the engagement shaft portion 153 is opposite to the projection direction of the rotation shaft portion 152. The engagement shaft portion 153 is located at a second end portion of the link 151 in the longitudinal direction.

[0044] As shown in Fig. 7, a first end of the lock lever spring 150S is engaged with the first base 110, and a second end of the lock lever spring 150S is engaged with the lock lever 150. In this way, the lock lever spring 150S biases the lock lever 150 in the first rotation direction R71. For this reason, the engagement shaft portion 153 of the lock lever 150 contacts the tip portion of the fifth arm 142 of the emergency lever 140, as shown in Fig. 8.

[0045] As shown in Figs. 7 and 8, the lock pin 160 is columnar. The lock pin 160 is inserted through the guide hole 124 of the RA lever 120, the guide groove 134a of the RP lever 130, and the slide groove 154 of the lock lever 150. In this way, the lock pin 160 connects the RA lever 120, the RP lever 130, and the lock lever 150. The lock pin 160 is immovable in the thickness direction of the RA lever 120, the RP lever 130, and the lock lever 150. On the other hand, the lock pin 160 is movable in a direction perpendicular to the thickness direction of the RA lever 120, the RP lever 130, and the lock lever 150. More specifically, the lock pin 160 is movable inside the guide hole 124 relative to the RA lever 120. Also, the lock pin 160 is movable along the guide groove 134a relative to the RP lever 130. Furthermore, the lock pin 160 is movable along the slide groove 154 relative to the lock lever 150. In the following description, the position of the lock pin 160 shown in Fig. 7 will be referred to as the "coupled position".

[0046] <Second remote control unit 102> 9 and 10, the second remote control unit 102 includes a second base 210, a close active lever 220, a close passive lever 230, and a cancel lever 240. The second remote control unit 102 also includes a connecting shaft 251, a close active lever support shaft 252, a cancel lever support shaft 253, a close passive lever spring 230S, and a cancel lever spring 240S. Furthermore, the second remote control unit 102 includes a second door lock drive unit 260, as shown in FIGS. 5 and 6.

[0047] In the following description, the close active lever 220 will be referred to as the "CA lever 220," and the close passive lever 230 will be referred to as the "CP lever 230." Additionally, the close active lever support shaft 252 will be referred to as the "CA lever support shaft 252," and the close passive lever spring 230S will be referred to as the "CP lever spring 230S."

[0048] As shown in Fig. 9, the second base 210 is plate-shaped. The second base 210 has a stopper 211 that determines the rotation range of the cancel lever 240. The stopper 211 is formed by cutting out a part of the second base 210. A CA lever support shaft 252 and a cancel lever support shaft 253 are fixed to the second base 210. The axis of the CA lever support shaft 252 and the axis of the cancel lever support shaft 253 both extend in the plate thickness direction of the second base 210.

[0049] As shown in Figs. 9 and 10, the CA lever 220 has a plate shape. The CA lever 220 has a base 221, a sector gear 222, and a seventh arm 223. The base 221 corresponds to the center of the CA lever 220. The CA lever 220 is rotatably supported by the CA lever support shaft 252 via the base 221. When the CA lever 220 is viewed from the plate thickness direction, the sector gear 222 has a sector shape centered on the base 221. The sector gear 222 has a gear train extending in an arc shape. The seventh arm 223 extends from the base 221.

[0050] The CP lever 230 has a swing arm 231, a balancer 232, and a roller 233. The swing arm 231 is in the shape of a long plate. A base end of the swing arm 231 in the longitudinal direction is connected to a tip end of the seventh arm 223 of the CA lever 220 by a connecting shaft 251. Thus, the CP lever 230 is rotatable relative to the CA lever 220 around the axis of the connecting shaft 251. A tip end of the swing arm 231 in the longitudinal direction rotatably supports the balancer 232. A second end of the upper close cable C3 and a second end of the lower close cable C4 are connected to the balancer 232. The roller 233 is in the shape of a disk. The roller 233 is located in the center between the base end and the tip end of the swing arm 231. The roller 233 may be rotatable with respect to the swing arm 231, or may be non-rotatable.

[0051] 9, a first end of the CP lever spring 230S is engaged with the seventh arm 223 of the CA lever 220, and a second end of the CP lever spring 230S is engaged with the swing arm 231 of the CP lever 230. In this way, the CP lever spring 230S biases the CP lever 230 in the first rotation direction R91 relative to the CA lever 220.

[0052] As shown in Figs. 9 and 10, the cancel lever 240 is plate-shaped. The cancel lever 240 is L-shaped when viewed from the front in the plate thickness direction. The cancel lever 240 is rotatably supported by the cancel lever support shaft 253. Here, the rotation axis of the cancel lever 240 coincides with the rotation axis of the RA lever 120, the rotation axis of the RP lever 130, and the rotation axis of the emergency lever 140. A first end of the cancel lever 240 contacts the roller 233 of the CP lever 230. Meanwhile, as shown in Fig. 9, a second end of the cancel lever 240 contacts the second pressing portion 142b of the emergency lever 140.

[0053] 9, a first end of the cancel lever spring 240S is engaged with the second base 210, and a second end of the cancel lever spring 240S is engaged with the cancel lever 240. In this way, the cancel lever spring 240S biases the cancel lever 240 in the first rotation direction R61. The cancel lever 240 is positioned by contacting the stopper 211 of the second base 210.

[0054] In the second remote control unit 102, the CP lever 230 is biased by the CP lever spring 230S. Therefore, a torque that rotates the CP lever 230 in the first rotation direction R91 is applied to the CP lever 230 by the CP lever spring 230S. Meanwhile, the restoring forces of the close lever springs 54S of the upper locking device 50 and the lower locking device 60 are applied to the close cables C3, C4 connected to the CP lever 230. In other words, the CP lever 230 is biased by the close cables C3, C4. Therefore, a torque that rotates the CP lever 230 in the second rotation direction R92 is applied to the CP lever 230 by the close cables C3, C4.

[0055] In this embodiment, the torque corresponding to the pulling force of the close cables C3, C4 is greater than the torque corresponding to the restoring force of the CP lever spring 230S. However, as shown in Fig. 9, the cancel lever 240 presses the roller 233 of the CP lever 230, so the CP lever 230 is restricted from rotating in the second rotation direction R92 relative to the CA lever 220. Therefore, as long as the cancel lever 240 presses the roller 233 of the CP lever 230, the CP lever 230 can rotate integrally with the CA lever 220. Furthermore, in the state shown in Fig. 9, the central axis of the roller 233 of the CP lever 230 and the center of rotation of the CA lever 220 are approximately aligned.

[0056] As shown in Fig. 5 and Fig. 6, the second door lock driving unit 260 includes an electric motor 261, a pinion 262 that rotates based on the power transmitted from the electric motor 261, and a case 263 that houses the components of the second door lock driving unit 260. Although not shown, the case 263 houses a reducer that transmits the rotation of the output shaft of the electric motor 261 to the pinion 262 while reducing the speed. The second door lock driving unit 260 is fixed to the second base 210 by a fastening member such as a screw. At this time, as shown in Fig. 9, the pinion 262 meshes with the sector gear 222 of the CA lever 220. In this respect, the second door lock driving unit 260 can drive the CA lever 220.

[0057] <Door drive unit 90> 1, the door drive unit 90 is disposed near one of the front links 31F. Although not shown, the door drive unit 90 preferably has an electric motor and a transmission mechanism that transmits the power of the electric motor to the front door 40F. The door drive unit 90 operates the front door 40F to open in the opening direction and to close in the closing direction.

[0058] <Cables C1 to C7> The multiple cables C1 to C7 are, for example, Bowden cables. The multiple cables C1 to C7 may be high-rigidity rods. The upper open cable C1 corresponds to the "first open cable," and the lower open cable C2 corresponds to the "second open cable." In addition, the upper closed cable C3 corresponds to the "first closed cable," and the lower closed cable C4 corresponds to the "second closed cable."

[0059] <Door control device 300> The door control device 300 is a processing circuit having a CPU and a memory. The memory stores a program executed by the CPU. The door control device 300 controls the first door lock driving unit 75, the second door lock driving unit 260, and the door driving unit 90 based on an operation command signal input from an opening / closing switch arranged around the driver's seat, around the front door 40F, or on a portable device.

[0060] When an opening operation command signal for opening the front door 40F is input, the door control device 300 causes the first door lock drive unit 75 to perform a release operation for releasing the restraint of the front door 40F from the vehicle body 20. Then, when the release operation is completed, the door control device 300 stops the first door lock drive unit 75 and causes the door drive unit 90 to open the front door 40F toward the fully open position. When the front door 40F reaches the fully open position, the door control device 300 stops the door drive unit 90.

[0061] When a closing operation command signal for the front door 40F is transmitted, the door control device 300 causes the door drive unit 90 to perform a closing operation of the front door 40F toward the fully closed position. When the front door 40F reaches a position near the fully closed position, the door control device 300 stops the door drive unit 90. Next, the door control device 300 causes the first door lock drive unit 75 and the second door lock drive unit 260 to perform a closing operation to restrain the front door 40F from the vehicle body 20. When the closing operation is completed, the door control device 300 stops the first door lock drive unit 75 and the second door lock drive unit 260. Furthermore, the door control device 300 returns the first door lock drive unit 75 and the second door lock drive unit 260 to their initial states before the start of the closing operation.

[0062] <Action of this embodiment> <Door lock device closing operation> The closing operation by the first door lock drive unit 75 and the second door lock drive unit 260 will be described together with the closing operation of the front door 40F by the door drive unit 90.

[0063] 2, when the front door 40F is positioned in the opening direction from the fully closed position, the upper locking device 50, the lower locking device 60, and the front locking device 70 are in an unlatched state. More specifically, the latch 51 is positioned at an unlatched position where the latch 51 rotates furthest in the first rotation direction R11 within the rotation range of the latch 51 due to the restoring force of the latch spring 51S. Also, the pole 52 is positioned at an engagement position where the pole 52 rotates furthest in the second rotation direction R22 within the rotation range of the pole 52 due to the restoring force of the pole spring 52S. The unlatched position is a position where the latch 51 cannot be engaged with the striker 22. Also, when the latch 51 is positioned at the unlatched position, the pole 52 positioned at the engagement position is not engaged with the latch 51.

[0064] When the front door 40F is moved to the vicinity of the fully closed position by the door drive unit 90, the states of the upper locking device 50, the lower locking device 60, and the front locking device 70 change. In detail, as shown by two-dot chain lines in Fig. 2, the striker 22 comes into contact with the latch 51 in the upper locking device 50, the lower locking device 60, and the front locking device 70. If the closing operation of the front door 40F continues after the striker 22 comes into contact with the latch 51, the latch 51 is pushed by the striker 22 to rotate in the second rotation direction R12. At this time, the pawl 52 rotates in the first rotation direction R21 from the locking position while sliding against the latch 51.

[0065] When the rotation of the latch 51 continues with the closing operation of the front door 40F, the pole 52 no longer slides against the latch 51. Then, the pole 52 rotates in the second rotation direction R22 due to the restoring force of the pole spring 52S. That is, as shown in FIG. 11, the pole 52 returns to the latching position where it is latched with the latch 51. Therefore, the latch 51 cannot rotate toward the unlatched position as long as the pole 52 remains in the latching position. Hereinafter, the position of the latch 51 shown in FIG. 11 is referred to as the half-latched position.

[0066] When the latch 51 rotates to the half-latched position, the driving of the door drive unit 90 is stopped. Then, the first door lock drive unit 75 and the second door lock drive unit 260 start the closing operation. Note that the timing when the first door lock drive unit 75 and the second door lock drive unit 260 start the closing operation may be before the driving of the door drive unit 90 ends.

[0067] First, the closing operation of the first door lock driving portion 75 will be described. As shown in Fig. 4, in the front lock device 70, the first door lock drive unit 75 rotates the close lever 71 in the first rotation direction R41. Then, as shown by the solid arrow in Fig. 11, the tip of the close lever 71 moves toward the latch 51. That is, the latch 51 is pushed by the close lever 71 to rotate in the second rotation direction R12. At this time, the pawl 52 rotates in the first rotation direction R21 from the locking position while sliding against the latch 51.

[0068] When the latch 51 continues to rotate in the second rotation direction R12 in accordance with the rotation of the close lever 71, the pole 52 no longer slides against the latch 51. Then, the pole 52 rotates in the second rotation direction R22 due to the restoring force of the pole spring 52S. That is, as shown in FIG. 12, the pole 52 returns to the latch position where it is latched with the latch 51. Therefore, the latch 51 cannot rotate toward the unlatched position as long as the pole 52 remains in the latch position. Hereinafter, the position of the latch 51 shown in FIG. 12 is referred to as the fully latched position, and the state of the front lock device 70 is referred to as the fully latched state. After the latch 51 rotates to the fully latched position, the first door lock drive unit 75 rotates the close lever 71 in the second rotation direction R42. As a result, the close lever 71 returns to the initial position before the start of the close operation. In other words, the close lever 71 moves away from the latch 51.

[0069] Next, the closing operation of the second door lock drive portion 260 will be described. As shown in FIG. 9, in the remote control device 100, the second door lock drive unit 260 rotates the CA lever 220 in a first rotation direction R81. In the state shown in FIG. 9, the CA lever 220 and the CP lever 230 rotate substantially integrally, so that the CP lever 230 rotates together with the CA lever 220 in the first rotation direction R81. As a result, as shown in FIG. 13, the CP lever 230 pulls the close cables C3 and C4 via the balancer 232. Then, as shown in FIG. 3, in the upper locking device 50 and the lower locking device 60, the close lever 54 rotates in the first rotation direction R41. As a result, similar to the front locking device 70, the latch 51 rotates to the full latch position, and the pole 52 is disposed in the locking position. That is, the upper locking device 50 and the lower locking device 60 transition to the full latch state. In this respect, the first rotation direction R81 corresponds to the "close direction".

[0070] After the latch 51 rotates to the fully latched position, in the remote control device 100, the second door lock drive unit 260 rotates the CA lever 220 in the second rotation direction R82. In the state shown in FIG. 13, the CA lever 220 and the CP lever 230 rotate substantially integrally, so that the CP lever 230 rotates together with the CA lever 220 in the second rotation direction R82. As a result, as shown in FIG. 9, the pulling of the close cables C3, C4 by the CP lever 230 is released. That is, as shown in FIG. 3, in the upper locking device 50 and the lower locking device 60, the close lever 54 rotates in the second rotation direction R42 according to the restoring force of the close lever spring 54S. As a result, the close lever 54 returns to the initial position before the start of the close operation. In other words, the close lever 54 moves away from the latch 51.

[0071] In this manner, the closing operation by the first door lock drive unit 75 and the second door lock drive unit 260 is completed. In this embodiment, the front lock device 70 transitions to a fully latched state by the closing operation of the first door lock drive unit 75. Similarly, the upper lock device 50 and the lower lock device 60 transition to a fully latched state by the closing operation of the second door lock drive unit 260. As a result, the front end, upper rear end, and lower rear end of the front door 40F are restrained by the vehicle body 20.

[0072] <Door lock device close cancel operation> As shown in Figures 9 and 13, in the closing operation, the second door lock driving unit 260 causes the remote control device 100 to pull the close cables C3, C4. In this way, the second door lock driving unit 260 transitions the upper locking device 50 and the lower locking device 60 from the half-latched state to the full-latched state. Here, consider a case where the second door lock driving unit 260 malfunctions while pulling the close cables C3, C4. The malfunction of the second door lock driving unit 260 refers to a case where the pulling of the close cables C3, C4 cannot be released, for example, when the electric motor 261 of the second door lock driving unit 260 breaks down or the CA lever 220 becomes stuck.

[0073] As shown in Figures 12 and 13, when the close cables C3, C4 are pulled in the upper locking device 50 and the lower locking device 60, the close lever 54 restricts the rotation of the latch 51 in the first rotation direction R11. Therefore, even if the first door lock driving unit 75 performs a release operation, the latch 51 cannot rotate toward the unlatched position. In other words, the first door lock driving unit 75 cannot shift the upper locking device 50 and the lower locking device 60 to the unlatched state. As a result, the front door 40F cannot be opened from the fully closed position. Therefore, even in the above case, a close cancel operation is performed to enable the lower locking device 60 and the front locking device 70 to be shifted to the unlatched state.

[0074] As shown in Fig. 13, in a situation where a close cancel operation is required, the CP lever 230 pulls the close cables C3, C4. In other words, a reaction force of the force pulling the close cables C3, C4 acts on the CP lever 230. However, the cancel lever 240 presses the roller 233 of the CP lever 230. Therefore, the CP lever 230 is restricted from rotating relative to the CA lever 220 in the second rotation direction R92 based on the reaction force.

[0075] The close cancel operation is started when the user pulls the emergency cable C7 via the operation unit 80. When the emergency cable C7 is pulled in the remote control device 100, the emergency lever 140 rotates in the second rotation direction R62. When the emergency lever 140 rotates in the second rotation direction R62, the second pressing portion 142b of the emergency lever 140 presses the cancel lever 240. As a result, the cancel lever 240 rotates in the second rotation direction R62. The second rotation direction R62 corresponds to the "forced release direction" for the emergency lever 140.

[0076] As shown in Fig. 13 and Fig. 14, when the cancel lever 240 rotates in the second rotation direction R62, the cancel lever 240 comes off the roller 233 of the CP lever 230. In other words, the cancel lever 240 rotates from a restricting position that restricts the relative rotation between the CP lever 230 and the CA lever 220 to an allowing position that allows the relative rotation between the CP lever 230 and the CA lever 220. Therefore, the CP lever 230 rotates around the axis of the connecting shaft 251 due to a reaction force of the force pulling the close cables C3, C4. In detail, the CP lever 230 rotates in the second rotation direction R92 relative to the CA lever 220, which cannot rotate. In this way, in the remote control device 100, the pulling of the close cables C3, C4 by the CP lever 230 is released.

[0077] 3, in the upper locking device 50 and the lower locking device 60, the close lever 54 rotates in the second rotation direction R42. Therefore, the close lever 54 is no longer present in the rotation direction toward the unlatched position of the latch 51. In other words, by performing the release operation, the upper locking device 50 and the lower locking device 60 can transition to the unlatched state.

[0078] The above has described the close cancel operation of the second door lock drive unit 260, but the above-mentioned problems may also occur when the first door lock drive unit 75 performs the close operation. For this reason, it is preferable that the close cancel operation be performed by pulling the emergency cable C7 for the first door lock drive unit 75 as well. Such a close cancel operation is described in, for example, JP 2016-30982 A.

[0079] <Door lock device release operation> The release operation by the first door lock drive unit 75 will now be described. 12, when the front door 40F is in the fully closed position, the upper locking device 50, the lower locking device 60, and the front locking device 70 are in the fully latched state. More specifically, in the upper locking device 50, the lower locking device 60, and the front locking device 70, the latch 51 is in the fully latched position, and the pole 52 is in the locking position. Therefore, the latch 51 cannot rotate toward the unlatched position.

[0080] As shown in FIG. 4, in the release operation, the first door lock driving unit 75 rotates the release lever 72 in the second rotation direction R52. Then, the release lever 72 pulls the release cable C6. As shown in FIG. 15, when the release cable C6 is pulled, the RA lever 120 rotates in the second rotation direction R62 in the remote control device 100. The RA lever 120 is connected to the RP lever 130 via the lock pin 160. Therefore, when the RA lever 120 rotates in the second rotation direction R62, the RP lever 130 rotates in the second rotation direction R62 together with the RA lever 120. In detail, the first side surface 125a of the RA lever 120 pushes the lock pin 160 in the second rotation direction R62, and the lock pin 160 pushes the RP lever 130 in the second rotation direction R62, so that the RP lever 130 rotates. As a result, the RP lever 130 pulls the open cables C1, C2, and C5.

[0081] Then, as shown in FIG. 3, in the upper locking device 50 and the lower locking device 60, the open lever 53 rotates in the second rotation direction R32. Also, as shown in FIG. 4, in the front locking device 70, the open lever 53 rotates in the second rotation direction R32. Therefore, as shown by the solid arrow in FIG. 12, the pawl 52 is pushed by the open lever 53 and rotates in the first rotation direction R21. That is, the pawl 52 is no longer engaged with the latch 51. As a result, the latch 51 rotates in the first rotation direction R11 according to the restoring force of the latch spring 51S, and is disposed in the unlatched position shown in FIG. 2. In other words, the upper locking device 50, the lower locking device 60, and the front locking device 70 transition to the unlatched state. In this respect, the second rotation direction R62 corresponds to the "release direction."

[0082] When the upper locking device 50, the lower locking device 60, and the front locking device 70 are in the unlatched state, as shown in FIG. 4, the first door lock driving unit 75 rotates the release lever 72 in the first rotation direction R51 to release the pulling of the release cable C6. As shown in FIG. 7, in the remote control device 100, when the pulling of the release cable C6 is released, the RA lever 120 rotates in the first rotation direction R61 due to the restoring force of the RA lever spring 120S. Also, the RP lever 130 rotates in the first rotation direction R61 due to the restoring force of the RP lever spring 130S. In this way, the RA lever 120 and the RP lever 130 return to their initial positions before the release operation. As a result, the pulling of the open cables C1, C2, and C5 is released. As shown in FIG. 3 and FIG. 4, in the upper locking device 50, the lower locking device 60, and the front locking device 70, the open lever 53 returns to its initial position before the release operation.

[0083] <Door lock device release cancel operation> As shown in Figures 4 and 15, in the release operation, the first door lock drive unit 75 pulls the open cables C1, C2, and C5 via the release cable C6 and the remote control device 100. In this way, the first door lock drive unit 75 transitions the upper lock device 50, the lower lock device 60, and the front lock device 70 from the fully latched state to the unlatched state. Here, consider a case where the first door lock drive unit 75 malfunctions while pulling the open cables C1, C2, and C5. The malfunction of the first door lock drive unit 75 refers to a case where the pulling of the open cables C1, C2, and C5 cannot be released, for example, when the electric motor of the first door lock drive unit 75 breaks down or the release lever 72 becomes stuck.

[0084] As shown in Fig. 15, in the upper locking device 50, the lower locking device 60, and the front locking device 70, when the open cables C1, C2, and C5 are pulled, the pole 52 cannot be engaged with the latch 51. Therefore, even if the first door lock driving unit 75 and the second door lock driving unit 260 can rotate the latch 51 to the fully latched position by performing the closing operation, they cannot hold the latch 51 in the fully latched position. In other words, the first door lock driving unit 75 and the second door lock driving unit 260 cannot transition the upper locking device 50, the lower locking device 60, and the front locking device 70 to the fully latched state. Therefore, even in the above case, a release cancel operation is performed to enable the upper locking device 50, the lower locking device 60, and the front locking device 70 to transition to the fully latched state.

[0085] As shown in Fig. 15, in a situation where a release cancel operation is required, the release cable C6 is in a pulled state. Therefore, the RA lever 120 cannot rotate in the first rotation direction R61. The RP lever 130 is connected to the RA lever 120 via a lock pin 160. More specifically, the lock pin 160 is in contact with a first side surface 125a that defines the first portion 125 of the RA lever 120. Therefore, the lock pin 160 cannot move in the first rotation direction R61. Since the lock pin 160 cannot move in the first rotation direction R61, the RP lever 130 cannot rotate in the first rotation direction R61 either.

[0086] The release cancel operation is started when the user pulls the emergency cable C7 via the operation unit 80. As shown in Fig. 15 and Fig. 16, in the remote control device 100, when the emergency cable C7 is pulled, the emergency lever 140 rotates in the second rotation direction R62 until it comes into contact with the stopper 112. Here, when the emergency lever 140 comes into contact with the stopper 112, the user cannot pull the emergency cable C7 via the operation unit 80. Therefore, when the emergency lever 140 comes into contact with the stopper 112, the user can recognize that he or she has operated the operation unit 80 by the required amount.

[0087] As shown in FIG. 15 and FIG. 16, when the emergency lever 140 rotates in the second rotation direction R62, it pushes the engagement shaft portion 153 of the lock lever 150. Therefore, the lock lever 150 rotates in the second rotation direction R72. When the lock lever 150 rotates in the second rotation direction R72, it pushes the lock pin 160 toward the axis of the lever support shaft 170. Then, the lock pin 160 moves along the slide groove 154 of the lock lever 150 and also moves along the guide groove 134a of the RP lever 130. In addition, the lock pin 160 moves inside the guide hole 124 of the RA lever 120. More specifically, the lock pin 160 moves from the first portion 125 to the second portion 126 of the guide hole 124.

[0088] 16, when the lock lever 150 rotates most in the second rotation direction R72, the lock pin 160 is no longer in contact with the first side surface 125a that defines the first portion 125 of the guide hole 124. In other words, the lock pin 160 displaces from a connection position that connects the RA lever 120 and the RP lever 130 so that they cannot rotate relative to each other to a disconnection position that allows the RA lever 120 and the RP lever 130 to rotate relative to each other. As a result, the RP lever 130 and the lock pin 160 become rotatable relative to the RA lever 120 in the first rotation direction R61.

[0089] However, when the emergency lever 140 rotates until it contacts the stopper 112, the first pressing portion 142a of the emergency lever 140 contacts the second arm 132 of the RP lever 130. Therefore, the rotation of the RP lever 130 in the first rotation direction R61 is restricted by the emergency lever 140.

[0090] Next, the user releases the operation of the operation unit 80, thereby releasing the pulling of the emergency cable C7. As shown in Fig. 17, when the pulling of the emergency cable C7 is released, the emergency lever 140 becomes rotatable in the first rotation direction R61, and therefore the RP lever 130 also becomes rotatable in the first rotation direction R61. Therefore, the RP lever 130 and the emergency lever 140 rotate in the first rotation direction R61 due to the restoring force of the RP lever spring 130S.

[0091] The emergency lever 140 returns to its initial position before the release cancel operation by contacting the stopper 111, and the RP lever 130 returns to its initial position before the release operation by contacting the stopper 113. When the RP lever 130 returns to its initial position, the pulling of the open cables C1, C2, C5 is released. As a result, as shown in Figures 3 and 4, in the upper locking device 50, the lower locking device 60, and the front locking device 70, the open levers 53 return to their initial positions before the release operation. In this way, the upper locking device 50, the lower locking device 60, and the front locking device 70 can be transitioned to a fully latched state by the close operation.

[0092] When the emergency lever 140 rotates in the first rotation direction R61, the emergency lever 140 moves away from the lock lever 150. However, as shown in Fig. 7 and Fig. 17, after the release cancel operation is performed, the position of the lock pin 160 is different, and therefore the lock lever 150 is disposed in a position different from the initial position.

[0093] <Effects of this embodiment> (1) If the first door lock drive unit 75 malfunctions while a release operation is being performed, a release cancel operation is performed. This allows the upper locking device 50, the lower locking device 60, and the front locking device 70 to transition to a fully latched state. On the other hand, if the first door lock drive unit 75 and the second door lock drive unit 260 malfunction while a close operation is being performed, a close cancel operation is performed. This allows the upper locking device 50, the lower locking device 60, and the front locking device 70 to transition to an unlatched state.

[0094] Here, the release cancel operation and the close cancel operation are performed by the user pulling the emergency cable C7 via the operation unit 80. In other words, the user does not need to perform different operations on the operation unit 80 when performing the release cancel operation and the close cancel operation. Therefore, the remote control device 100 can improve the convenience for the user when the release cancel operation and the close cancel operation are performed. In other words, the remote control device 100 can make the operation for releasing the pulling of the close cables C3, C4 and the operation for releasing the pulling of the open cables C1, C2 easy for the user to understand.

[0095] (2) In the release cancel operation, the remote control device 100 moves the lock pin 160 from the coupled position to the uncoupled position in response to the rotation of the emergency lever 140. In this way, the remote control device 100 allows the rotation of the RP lever 130 relative to the RA lever 120. Therefore, the remote control device 100 can achieve the release cancel operation with a relatively simple configuration.

[0096] (3) In the close cancel operation, the remote control device 100 rotates the cancel lever 240 from the restricted position to the permitted position in response to the rotation of the emergency lever 140. In this way, the remote control device 100 permits the rotation of the CP lever 230 relative to the CA lever 220. Therefore, the remote control device 100 can achieve the close cancel operation with a relatively simple configuration.

[0097] (4) In the remote control device 100, the rotation axes of the RA lever 120, the RP lever 130, the cancel lever 240, and the emergency lever 140 are aligned. This reduces the transmission loss during power transmission between the RA lever 120, the RP lever 130, and the emergency lever 140. In addition, the transmission loss during power transmission between the emergency lever 140 and the cancel lever 240 is reduced.

[0098] (5) The vehicle 10 includes a first door lock drive unit 75 for performing a closing operation on the front lock device 70, and a second door lock drive unit 260 for performing a closing operation on the upper lock device 50 and the lower lock device 60. Therefore, a large door lock drive unit is not required compared to a case where a single door lock drive unit performs the closing operations of the upper lock device 50, the lower lock device 60, and the front lock device 70.

[0099] The torque required to release the door lock devices is smaller than the torque required to close the door lock devices, so the release operations of the upper lock device 50, the lower lock device 60, and the front lock device 70 can be performed by a single, compact first door lock drive unit 75.

[0100] (6) When the front door 40F is disposed in the fully closed position, if the first door lock drive unit 75 of the front lock device 70 malfunctions, the front door 40F cannot be opened. In this regard, the remote control device 100 rotates the emergency lever 140 in the second rotation direction R62 by pulling the emergency cable C7 by operating the operation unit 80. In this case, the RP lever 130 rotates in the second rotation direction R62 by being pressed by the first pressing portion 142a of the emergency lever 140. That is, the RP lever 130 pulls the open cables C1, C2, and C5. In this way, the remote control device 100 can release the front door 40F from being restrained against the vehicle body 20 in the fully closed position.

[0101] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

[0102] In the close cancel operation, the pulling of the close cables C3, C4 by the CP lever 230 may be released by linearly displacing the CP lever 230 relative to the CA lever 220. Similarly, in the release cancel operation, the pulling of the open cables C1, C2, C5 by the RP lever 130 may be released by linearly displacing the RP lever 130 relative to the RA lever 120.

[0103] In the remote control device 100, the rotation axes of the RA lever 120, the RP lever 130, the emergency lever 140, and the cancel lever 240 do not have to coincide. This eliminates the need to consider overlapping of multiple levers when designing and assembling the remote control device 100.

[0104] The configuration of the rear door 40R may be different from the configuration of the front door 40F. For example, one of the front door 40F and the rear door 40R may be provided with a center striker, and the other of the front door 40F and the rear door 40R may be provided with a center lock device that can be locked to the center striker.

[0105] The front door 40F may include only the first door lock driving unit 75 out of the first door lock driving unit 75 and the second door lock driving unit 260. In this case, it is preferable that the first door lock driving unit 75 and the remote control device 100 are configured to be able to pull the close cables C3 and C4 in the closing operation.

[0106] In the front door 40F, the arrangement of the two door lock devices, the upper lock device 50 and the lower lock device 60, may be changed as appropriate. For example, the two door lock devices may be arranged side by side in the front-rear direction along the lower edge of the front door 40F.

[0107] In the front door 40F, the first door lock drive unit 75 does not have to be configured integrally with the front lock device 70. Similarly, in the front door 40F, the second door lock drive unit 260 does not have to be configured integrally with the remote control device 100.

[0108] The front door 40F may be a sliding door that opens and closes the front opening 21F by moving in the front-rear direction. The vehicle 10 may be provided with either the front door 40F or the rear door 40R.

[0109] The remote control device 100 can also be applied to a back door that opens and closes an opening at the rear of the vehicle body 20. <Additional Notes> The technical ideas that can be understood from the above-described embodiment and modified examples will be described.

[0111] [Aspect 2] The remote control device described in aspect 1 includes a lock pin that displaces between a connected position that connects the release active lever and the release passive lever so that they cannot rotate relative to each other and a disconnected position that allows the release active lever and the release passive lever to rotate relative to each other, and a lock lever driven by the emergency lever, and it is preferable that the lock lever displaces the lock pin from the connected position to the disconnected position when the emergency lever rotates in the forced release direction.

[0112] [Aspect 3] The remote control device according to aspect 1 or aspect 2 further comprises a cancel lever which is driven by the emergency lever and displaces between a restricting position which restricts the relative rotation of the close passive lever and the close active lever and a permissible position which permisses the relative rotation of the close passive lever and the close active lever, and it is preferable that the cancel lever displaces from the restricting position to the permissible position when the emergency lever rotates in the forced release direction.
