Represent that as Fig. 3 and Fig. 5 lock slider 33 has the line of rabbet joint 33e (line of rabbet joint portion) of curved shape at bottom surface sections 33d.This line of rabbet joint 33e comprises: first α of hole portion that extends in parallel with moving direction, and second β of hole portion, second β of hole portion form with this first hole α of portion continuously and with the directional smoothing bending of moving direction approximate vertical.
Locking mechanism 60 at switch door 1 describes in detail now.Fig. 7 is the cut-away section schematic diagram of the locking mechanism that is in the lock state 60 seen from horizontal direction.In Fig. 7, planetary gears is positioned at the C1 side, and sliding door is in the C2 side.This locking mechanism 60 is the mechanisms of operating in horizontal plane, and is installed into the upside (planetary gears 20 sides) of the bottom surface sections 33d of contiguous lock slider 33, and with respect to substrate 5 fix in position (consulting Fig. 2, Fig. 4).
Represent that as Fig. 3 and Fig. 5 locking mechanism 60 is made of with the connecting rod maintaining body of operating 65 linkage 61 of deformable in horizontal plane by linear state or case of bending in horizontal plane.Linkage 61 forms by connecting three connecting rod 62a, 62b, 62c.Center linkage 62a is fixed into by means of connecting pin 63a at its vertical central portion can be with respect to substrate 5 rotations.The end of this center linkage 62a is connected to the end of connecting rod 62b by connecting pin 63b.The other end of center linkage 62a is connected to the end of connecting rod 62c by means of guiding connecting pin 63c.Connecting rod 62b and connecting rod 62c have pin 63d and 63e at the place, end with the tie point opposite side of connecting rod 62a.
As Fig. 3, Fig. 5 and shown in Figure 7, the pin 63d, the 63e that are in linkage 61 ends insert described end among guide channel 80A, the 80B respectively, guide channel 80A, 80B (representing with two short dash lines with the long dotted line that replaces in Fig. 3, Fig. 5) form point-blank and are parallel with the moving direction of lock slider 33, and described pin is installed along the mode that described guide channel 80A, 80B move with permission.That is moving of pin 63d, 63e uses restraint by means of guide channel 80A, 80B respectively.Sell the end formation roller (consulting Fig. 7) that 63d and 63e insert guide channel 80A, 80B, thereby allow the friction of minimizing and guide channel 80A, 80B, and can carry out moving of described end smoothly.Pin 63d and 63e also form roller (consulting Fig. 7) in the end of lock slider 33 sides, thereby allow to reduce the friction when the edge portion of hereinafter described engagement member 66A, 66B moves, but and steady lock operation.
The end of lock slider 33 sides of the guiding connecting pin 63c of linkage 61 forms roller, and inserts in the line of rabbet joint 33e of above-mentioned lock slider 33.Therefore, guide the position of connecting pin 63c by means of the position constraint of lock slider 33.Thereby, utilize the mobile linkage 61 that makes of lock slider 33 between linear state and case of bending, to switch.
Connecting rod maintaining body 65 constitutes by pair of engaging member 66A, 66B and with described pair of engaging member connection spring 69 connected to one another, and install with respect to linkage 61 (with respect to connecting pin 63a) symmetrically in the mode that allows to rotate in horizontal plane described pair of engaging member 66A, near the position of the 66B respective end of this linkage 61.Described engagement member 66A, 66B have the first junction surface 67A, 67B and the second junction surface 68A, 68B at its circumference respectively, and axis of rotation 81A, the 81B of engagement member 66A, 66B are fixedly mounted on the substrate 5 and (consult Fig. 7).Be fixed with cross-over connection member 82 on described pair of rotary shafts 81A, 81B, being used to rotate fixedly, the connecting pin 63a of the center linkage 62a of aforementioned link mechanism 61 supports (consulting Fig. 2, Fig. 4) by this cross-over connection member 82.
Be not subjected at connecting rod maintaining body 65 under the state of external force, engagement member 66A, 66B receive from the power that connects spring 69, and remain on the state that Fig. 3 represents.In this state, engagement member 66A, 66B move towards the extension of linear state by means of its outer edge (part of arrow P 2 expressions among Fig. 3) constrained linkage mechanism 61.Thereby, when linkage 61 by means of engagement member 66A, when 66B remains on case of bending, lock slider 33 is moving along locking direction A1 via line of rabbet joint 33e and guiding connecting pin 63c constraint.
On the other hand, engagement member 66A, 66B form by means of with respect to fixing respectively stop pin 14A, the 14B of sliding door 11A, 11B towards the closing direction (direction of arrow B 1 expression among Fig. 3; Hereinafter referred to as " closing direction B1 ") move and when promoting the edge portion (part that P1 represents among Fig. 3) of the first junction surface 67A, 67B, can overcome the motive force that connects spring 69 and rotate in the direction that makes the second junction surface 68A, 68B near linkage 61 (direction that arrow R1 represents among the 3rd figure).11A, 11B are under the state of contract fully position at sliding door, as shown in Figure 5, stop pin 14A, 14B engage with the first junction surface 67A, 67B, and the position of the second junction surface 68A, 68B is to allow and the pin 63d that is arranged on place, linkage 61 ends, the position that 63e engages.That is engagement member 66A, 66B enter the not state of constrained linkage mechanism 61 distortion.At this moment, if lock slider 33 moves with locking direction A1, make linkage 61 be converted to linear state by means of guiding connecting pin 63c along line of rabbet joint 33e mobile so from case of bending.Then, being in the pin 63d, the 63e that locate linkage 61 ends engages with the second junction surface 68A, the 68B of engagement member 66A, 66B.Retrain the rotation of engagement member 66A, 66B thus.Therefore, can be by means of the first junction surface 67A, 67B constraint stop pin 14A, 14B in the opening direction (direction of representing with arrow B 2 among Fig. 3, Fig. 5.Hereinafter referred to as " opening direction B2 ") move.
On/Off and the lock operation of sliding door 11A, 11B are described now with reference to Fig. 2～Fig. 5.Fig. 2 illustrates the mode that sliding door 11A, 11B move towards closing direction B1, and shows the state of the latch-release of locking mechanism 60.In this state, stop pin 14A, 14B are in the position away from locking mechanism 60, and locking mechanism 60 is maintained at the state that Fig. 3 represents.
In this latch-release state, linkage 61 is case of bending, moves by the straight line extension of engagement member 66A, 66B constrained linkage mechanism 61.Thus, guiding connecting pin 63c and the line of rabbet joint 33e via linkage 61 retrains lock slider 33 moving towards locking direction A1.
Therefore, in the latch-release state of Fig. 2, Fig. 3, the sun gear 21 of planetary gears 20 is by above-mentioned electrical motor driven, driving force is passed to pinion 9 via annulus 22, perhaps transmits via the planet carrier that rotates with the revolution of planet gear 24 23 and makes torque-limiting spring 71 elastic deformations.
At this, torque-limiting spring 71 promotes to be connected in the driving component 70 of planet carrier 23, make to suppress the predetermined elastic force that planet carrier 23 rotates along with the revolution of planetary gear 24 and act on planet carrier 23, thus the running resistance balance when carrying out normal closing motion with sliding door 11A, 11B.Therefore, when normal closing motion, the sun gear 21 of planetary gears 20 is by electrical motor driven, and planetary gear 24 is unjust then only carry out rotation, therefore all driving forces of sun gear 21 all are delivered to pinion 9 via annulus 22, and sliding door 11A, 11B are actuated to On/Off.
And, even sliding door 11A, 11B move with closing direction B1, engagement member 66A, the 66B of the locking mechanism 60 that engages with stop pin 14A, 14B also receive the elastic force that is connected spring 69, thereby be maintained at the state that Fig. 3 represents, and can not rotate to latched position (position that Fig. 5 represents), till sliding door 11A, 11B arrive the contract fully position.Thus, can before arriving the contract fully position, sliding door 11A, 11B prevent that locking mechanism 61 from moving too early.Therefore, since stop pin 14A, 14B collide with the engagement member 66A, the 66B that have entered latched position and can not cause locking mechanism 60 to break down.
When during the closing motion of sliding door 11A, 11B because passenger when the running resistance that causes sliding door 11A, 11B such as being pressed from both sides and obviously increasing, as described later, planet carrier 23 overcomes the motive force that causes owing to torque-limiting spring 71 and rotates, detect the rotation of this planet carrier 23, make the rotation of electro-motor temporarily stop or correspondingly carrying out the predetermined safe action.
Then, should expect that owing to driving sun gear 21 towards the direction of closing sliding door 11A, 11B, sliding door 11A, 11B are near the contract fully position, and the stop pin 14A, the 14B that fix with respect to sliding door 11A, 11B contact (consulting Fig. 3) with engagement member 66A, 66B.Making sliding door 11A, 11B when closing direction B1 is moved further from this state-driven sun gear 21, stop pin 14A, 14B promote engagement member 66A, 66B, and enter into the recess of the first junction surface 67A, 67B, make engagement member 66A, 66B rotate simultaneously in the arrow R1 of Fig. 3 direction.
When sliding door 11A, 11b arrive the contract fully position, engagement member 66A, 66B are bonded on the first junction surface 67A, 67B with stop pin 14A, 14B, and finish moving towards latched position, in latched position, the second junction surface 68A, 68B are towards the pin 63d, the 63e that are in linkage 61 ends.Thus, allow the transformation of linkage 61 towards linear state.Therefore when sliding door 11A, 11B moved to the contract fully position, lock slider 33 can move towards locking direction A1, and lock slider 33 is connected to linkage 61 via guiding connecting pin 63c and line of rabbet joint 33e, and linkage 61 is arrived linear state by allowed transition.As a result, the rotation of the planet carrier 23 that is connected with lock slider 33 by means of torque-limiting spring 71 and driving component 70 tolerables.
On the other hand, when in a single day sliding door 11A, 11B arrive the contract fully position, just can not move with closing direction B1.Therefore, also can stop the rotation that is connected to the annulus 22 of sliding door 11A, 11B via rack and pinion mechanism 10.Therefore, the driving force that continues the sun gear 21 of rotation passes to planet carrier 23 at this moment, make planet carrier 23 rotate with counterclockwise in Fig. 2, and lock slider 33 moves at locking direction A1 via torque-limiting spring 71 and driving component 70.Along with lock slider 33 the moving of locking direction A1, linkage 61 is converted to linear state (state shown in Figure 5) from case of bending (state shown in Figure 3).In linear state, the rotation of engagement member 66A, 66B is retrained by pin 63d, the 63e of linkage 61.Therefore stoped mobile with the first junction surface 67A of engagement member 66A, 66B, stop pin 14A, 14B that 67B engages.Therefore, moving of sliding door 11A, 11B locks via described stop pin 14A, 14B.Locking spring 73 is installed on the guide shaft 72, and locking spring 73 promotes the installation portion 33a of lock slider 33 towards locking direction A1, and this lock slider 33 that has suppressed to be in latched position is got back to the latch-release position, and allows to keep more reliably lock-out state.
Therefore as shown in the figure, be deformed into Fig. 4 and state shown in Figure 5 by means of state from Fig. 2 and Fig. 3 demonstration, after sliding door 11A, 11B moved to the contract fully position, locking mechanism 60 automatically switched to lock-out state, and will pull thus 11A, 11B are locked in closed condition.Therefore, the sun gear 21 that can be only drives planetary gears 20 with single actuator realize and the pull locking of closing interlock of 11A, 11B can simplify driving structure.
And, under Fig. 4 and lock-out state shown in Figure 5, can impose dual locking, promptly, can apply the locking of rotating, and retrain the locking that these linkages 61 are out of shape from linear state towards case of bending by means of lock slider 33 by means of linkage 61 constraint engagement member 66A, 66B.Even for example entering thus because of the power failure of vehicle or fault etc. can not supply power to the state of electro-motor and output shaft (above-mentioned sun gear 21) when freely rotating, the unlatching of also can prevent from very reliably to pull 11A, 11B by means of above-mentioned double locking structure.Even this means that vehicle take place to have a power failure, also still can prevent to pull 11A, 11B are not intended to unlatching because of blast etc.
In order to switch to the latch-release state from above-mentioned lock-out state and to open sliding door 11A, 11B, only utilize above-mentioned electro-motor that sun gear 21 is got final product towards driving in the opposite direction with the side of closing closed procedure simply.In lock-out state (Fig. 4 and Fig. 5),, thereby stop the rotation of annulus 22 because sliding door 11A, 11B are engaged member 66A, 66B locking.On the other hand, lock slider 33 is towards the latch-release direction (direction of arrow A 2 expressions among Fig. 3, Fig. 5; Hereinafter referred to as " latch-release direction A2 ") the motive force that only moves by means of locking spring 73 suppressed.That is in this state, if the driving force opposite with these locking spring 73 motive forces passes to lock slider 33, lock slider 33 can move at latch-release direction A2 so.Therefore, when from lock-out state with sun gear 21 when driving in the opposite direction with the side of closing closed procedure, all driving forces of sun gear 21 all are passed to planet carrier 23, and lock slider 33 is through the motive force of driving component 70 opposing locking springs 73 and move towards latch-release direction A2.Along with this lock slider 33 towards the moving of latch-release direction A2, the guiding connecting pin 63c of linkage moves to second β of hole portion along the edge portion of line of rabbet joint 33e from first α of hole portion, makes linkage 61 be converted to case of bending from linear state thus.Therefore, make the disengaging that engages of the second junction surface 68A, 68B with the pin 63d, the 63e that are in linkage 61 ends of engagement member 66A, 66B.So by means of the tensile-elasticity of the connection spring 69 that connects described pair of engaging member 66A, 66B, engagement member 66A, 66B receive junction surface 67A, the 67B power of (with linkage 61 opposition sides) toward the outer side of winning that makes.That is engagement member 66A, 66B receive the power that makes that described member rotates along the R2 direction in Fig. 5.Therefore, stop pin 14A, 14B that tolerable and the second junction surface 68A, 68B are in engagement state move towards opening direction B2, and remove the locking of sliding door 11A, 11B.
In position shown in Figure 2, lock slider 33 retrains towards the deformation limit of the mobile locked spring 73 of latch-release direction A2.Lock slider 33 retrains towards the mobile deformation limit that is not limited to locked spring 73 of latch-release direction A2, also can impose restriction by planet carrier 23 is contacted with substrate 5.And, can suitably set the length of guide channel 80A, 80B, make by means of the distortion of moving constrained linkage mechanism 61 that retrains described pin 63d, 63e by guide channel 80A, 80B, therefore lock slider 33 is mobile restrained, and wherein pin 63d, the 63e of linkage 61 insert among guide channel 80A, the 80B.
Because lock slider 33 is mobile restrained towards latch-release direction A2's, the driving force of the sun gear 21 of planetary gears 20 can be delivered to annulus 22 sides this moment.Therefore, sliding door 11A, 11B is driven towards opening direction B2 via rack and pinion mechanism 10.In this process, make described member towards the power (power of the R2 direction of Fig. 5) of latch-release rotated position because engagement member 66A, 66B receive from what connect spring 69, so engagement member 66A, 66B can not retrain moving of stop pin 14A, the 14B fixing with respect to sliding door 11A, 11B.
Can provide with lock slider 33 be arranged on the structure that is connected via not shown line or other connecting elements from the not shown bar of vehicle interior or outside come-at-able position, the people operates this bar when the emergency to allow, make lock slider move in the direction of disarm state, thereby unlock manually opened then sliding door 11A, 11B.As simpler structure, this bar can directly be fixed to lock slider 33.
The situation that to use Fig. 8 and Fig. 9 explanation one of them side's (sliding door from fully open position when move the contract fully position) sliding door 11A and the sliding door 11B when the closing motion of sliding door 11A, 11B running resistance obviously to increase now.This is corresponding to the situation that for example has the passenger to be clamped by the 11A that pulls, 11B or sliding door and passenger's case of collision.Fig. 8 is the schematic diagram of the state of planet carrier 23 when normal closing motion.The schematic diagram of the state of planet carrier 23 when Fig. 9 is the running resistance increase of pulling during closing motion.
When the closing motion of the 11A that normally pulls, 11B, promptly at two sliding doors 11A, 11B under not from the situation of the mobile obstruction of outside during with normal running resistance operation, as mentioned above, the driving force of sun gear 21 is delivered to annulus 22 sides, drives towards closing direction B1 via will pull 11A, 11B of rack and pinion mechanism 10.This is because as mentioned above when sliding door 11A, 11B are in position beyond the contract fully position, lock slider 33 mobile restrained.That is under the mobile restrained state of this lock slider 33, the driving component 70 that is connected to planet carrier 23 is promoted with the predetermined elastic force that can suppress these planet carrier 23 rotations by torque-limiting spring 71.In the present embodiment, make and suppress the elastic force that planet carrier 23 rotates and act on the planet carrier 23 via driving component 70, so as with the running resistance balance of sliding door 11A, 11B.That is, when the masterpiece that is not less than normal running resistance during closing motion is used to pull 11A, 11B, planet carrier 23 can rotate, thereby enters state shown in Figure 9, makes simultaneously torque-limiting spring 71 elastic deformations under the situation about being maintained fixed in the position of lock slider 33.
The outer peripheral edges portion of planet carrier 23 is fixed with permanent magnet 83, and the sense switch 84 (collision detection unit, limit switch) that is installed in substrate 5 sides is arranged to move with the rotation of planet carrier 23 by means of permanent magnet 83 and is switched.Particularly, the position of the planet carrier 23 when sliding door 11A, 11B move with normal running resistance, this sense switch 84 is in the OFF state.On the other hand, when planet carrier 23 rotated scheduled volume along with the increase of sliding door 11A, 11B running resistance, this sense switch 84 became ON state (consulting Fig. 9).When this sense switch 84 switched to the ON state, the signal that stops to drive sent electro-motor to, and stopped the driving of electro-motor.
By means of above-mentioned setting, when during the closing motion of sliding door 11A, 11B because feasible sliding doors such as sliding door clamping passenger or opposite opened sliding door and passenger's collision during towards the running resistance increase of closing direction B1, the driving that can stop electro-motor imposing on the passenger's who is clamped by pull 11A, 11B etc. impact force with mitigation.When being clamped or colliding (detected by door) action of carrying out is not limited to stop the driving of electro-motor when sense switch 84 is in the ON state, also can control to reduce the driving output of electro-motor.
Carry out such setting: make at sliding door 11A, 11B when being in the contract fully position, even the above-mentioned signal that stops to drive electro-motor does not transmit or described signal is transmitted the driving that also can not stop electro-motor.Therefore, can not stop the driving of electro-motor during towards the shift action of locking direction A1 at above-mentioned lock slider 33.
Also such structure can be arranged: for example, provide and detect the lock-out state detecting sensor that sliding door is in the lock state, if and above-mentioned sense switch 84 sends after the detection signal, this lock-out state detecting sensor is not sent detection signal in the given time, judge then that the sliding door that is produced by sliding door is clamped or the generation of collision etc., and stop to drive electro-motor.And, for example also can be used in combination the deceleration sensor that detects the deceleration of pulling.In the case, in closing motion when the translational speed of sliding door when big, by means of the rotation that above-mentioned sense switch 84 detects planet carriers can decision gate clamp, collision etc., and near sliding door arrives fastening position and the translational speed of sliding door when slowing down, can carry out that door is clamped by means of deceleration sensor, the detection of collision etc.
As mentioned above, opening and closing apparatus with lock according to present embodiment comprises: rack and pinion mechanism 10, described rack and pinion mechanism 10 has a pair of tooth bar 7A, 7B and the pinion 9 that is installed in respectively on a double-wing door 11A, the 11B that can come and go the opposite opened that moves with respect to the housing (wall) of vehicle, described pinion 9 and described a pair of tooth bar 7A, 7B engagement; Electro-motor as the ON/OFF drive source of above-mentioned sliding door 11A, 11B; Locking mechanism 60, described locking mechanism 60 is installed on the substrate 5 that attaches to housing, to be locked in the contract fully position by means of a mobile above-mentioned double-wing door 11A, the 11B of making that retrains stop pin 14A, 14B respectively, described stop pin 14A, 14B are individually fixed in the corresponding sliding door of an above-mentioned double-wing door 11A, 11B; Lock slider 33 is used to make above-mentioned locking mechanism 60 to switch between lock-out state and latch-release state; And, planetary gears 20, described planetary gears 20 has sun gear 21, driving force can be exported to the annulus 22 and the planet carrier 23 of above-mentioned pinion 9, and the driving force of above-mentioned electro-motor is imported described sun gear 21, and planet carrier can be exported to driving force lock slider 33; And be arranged so that above-mentioned driving force is exported to above-mentioned lock slider 33 from above-mentioned planet carrier 23 at above-mentioned sliding door 11A, when 11B is positioned at the contract fully position.
By means of above-mentioned structure, retrained by locking mechanism 60 respectively owing to be individually fixed in the moving of stop pin 14A, 14B of each sliding door of a double- wing door 11A, 11B, therefore can independently lock each among a described double-wing door 11A, the 11B.Thus, even rack and pinion mechanism 10 breaks down, moving of two sliding doors 11A, 11B also can remain on lock-out state.On the contrary, when rack and pinion mechanism 10 normal operations, even the locking of a sliding door 11A (11B) hinders for some reason etc. and removes, because a described sliding door 11A (11B) is connected with another sliding door 11B (11A) via rack and pinion mechanism 10, therefore as long as the locking of another sliding door 11B (11A) is effective, this sliding door 11A (11B) can be maintained lock-out state.Therefore, can carry out the sliding door 11A of opposite opened, the locking of 11B more reliably.
And by means of this structure, the power of electro-motor distributes via planetary gears 20, so that drive the pinion 9 of rack and pinion mechanism 10 on the one hand, drives lock slider 33 on the other hand.Therefore, owing to be used for being incorporated in the tight space from the structure of electro-motor transmission (distributions) power, therefore can simplified structure, and the opening and closing apparatus with lock of compactness is provided.
In addition, owing to being not uses buffer spring as patent documentation 1 to be to use planetary gears 20 to distribute driving force from electro-motor, therefore be locked under the state of fastening position at sliding door 11A, 11B, even because of electro-motor fault etc. loses driving force, the power of latch-release direction can not be applied to lock slider 33 etc. yet, and prevents unexpected latch-release.
And, having lock slider 33 according to the opening and closing apparatus with lock of present embodiment, lock slider 33 makes above-mentioned locking mechanism 60 switch between lock-out state and latch-release state by means of moving along with the driving of above-mentioned planet carrier 23.Above-mentioned locking mechanism 60 is arranged so that when above-mentioned sliding door 11A, 11B are positioned at position beyond the contract fully position and stops moving of above-mentioned lock slider 33, allows when being positioned at the contract fully position that at above-mentioned sliding door 11A, 11B above-mentioned lock slider 33 moves.
By means of this structure, stop moving of lock slider 33 during owing to the position beyond sliding door 11A, 11B are in the contract fully position, so when sliding door 11A, 11B arrive the contract fully position reliably, just conduct the locking operations.That is, can when closing direction B1 drives, prevent to conduct the locking operations prematurely at sliding door 11A, 11B, thereby prevent that the damaged of locking mechanism 60 or sliding door 11A, 11B are promptly restrained before arrival contract fully position.
And in the opening and closing apparatus with lock according to present embodiment, above-mentioned locking mechanism 60 comprises: along with the linkage 61 that can be out of shape between linear state and case of bending that moves of above-mentioned lock slider 33; And, when above-mentioned sliding door is positioned at position beyond the contract fully position, this linkage 61 is remained on the connecting rod maintaining body 65 of case of bending.By means of this locking mechanism 60, at above-mentioned sliding door 11A, when 11B is positioned at the contract fully position, this linkage 61 is deformed into linear state, and constraint is individually fixed in the moving of stop pin 14A, 14B of above-mentioned sliding door 11A, 11B thus.
By means of this structure, by making linkage 61 be in linear state, moving of sliding door 11A, 11B can be locked in the contract fully position, and because in the position beyond the contract fully position, linkage 61 remains on case of bending by means of connecting rod maintaining body 65, therefore just conduct the locking operations after sliding door 11A, 11B arrive the contract fully position.Thereby owing to use linkage 61 to drive locking mechanisms 60, locking mechanism 60 can form compactly, and because locking mechanism 60 is driven by mechanical type, therefore can realize stable driving.
In addition, have stop pin 14A, 14B according to the opening and closing apparatus with lock of present embodiment, described stop pin 14A, 14B are fixed in above-mentioned sliding door 11A, 11B so that extend towards vertical direction.Above-mentioned connecting rod maintaining body 65 is made of pair of engaging member 66A, 66B, described pair of engaging member 66A, 66B have the first junction surface 67A, 67B and the second junction surface 68A, 68B, the first junction surface 67A, 67B are rotatably installed near the both ends of aforementioned link mechanism 61, and engage with above-mentioned stop pin 14A, 14B in the contract fully position, the second junction surface 68A, 68B are in contract fully position and the engaged at end that is in the aforementioned link mechanism 61 of linear state.When above-mentioned sliding door 11A, 11B are in position beyond the contract fully position, above-mentioned engagement member 66A, 66B stop above-mentioned lock slider 33 to move by stoping aforementioned link mechanism 61 towards the transformation of linear state, when above-mentioned sliding door 11A, 11B move towards closing direction B1, allow above-mentioned lock slider 33 to move, thereby rotate to the position that the end that makes aforementioned link mechanism 61 engages with the above-mentioned second junction surface 68A, 68B by the promotion of above-mentioned stop pin 14A, 14B.
