In the upper part of the slide door 30, a side-view rectangular window hole 31 is formed. Inside the sliding door 30, a side-view square window glass 33 is provided so as to be slidable in the vertical direction. The window glass 33 is linked to a known window regulator (not shown) provided in the slide door 30, and this window regulator is connected to a window opening / closing motor provided in the slide door 30. When the window opening / closing motor rotates by operating a door switch (not shown) provided in the vehicle, the window regulator is operated by the driving force of the window opening / closing motor, and the window glass 33 completely closes the window hole 31. It moves up and down between the closed position and the fully open position where the window hole 31 is completely opened. An inside handle 35 is provided on the inner side surface of the sliding door 30, and an outside handle 36 is provided on the outer side surface of the sliding door 30. Both the inside handle 35 and the outside handle 36 are rotatable between a non-operation position and an open position.
A known lock device 200 having a hook and a pole that can be engaged with and disengaged (locked and unlocked) is provided at the front end of the slide door 30. As is known, the locking device 200 can lock the full-close striker 27 when the inside handle 35 and the outside handle 36 are in the non-operating position, and when the inside handle 35 or the outside handle 36 is in the open position. The fully closed striker 27 cannot be locked (unlocked).
Furthermore, a locking device 40 that can be engaged with and disengaged from the full-open striker 25 and the intermediate striker 26 is provided on the front end side of the lower end portion of the slide door 30.

The lock device 40 has the following structure.
A fixed substrate 42 parallel to the ground (that is, horizontal) is fixed to the bottom surface of the slide door 30. A mounting piece 43 projects from the rear end of the fixed substrate 42. A bracket 45 smaller in size than the fixed substrate 42 is fixed to the upper surface of the fixed substrate 42. The front end portion of the upper surface of the bracket 45 is a stopper portion 46 that protrudes upward as compared with other portions. The stopper portion 46 is directed substantially in the front-rear direction, the rear end surface thereof is a first hook stopper 47 that is vertical, the inner end surface thereof is vertical and substantially in the front-rear direction, and the interlocking lever stopper surface 48 and the switching lever stopper surface (stopper). 49. Further, on the upper surface of the bracket 45, three pivot shafts 50, pivot shafts 51, and pivot shafts 52, each of which has a cylindrical shape, project upward. On the inner edge of the bracket 45, a first pole stopper 54 bent upward and a mounting piece 55 bent so as to form an L shape in plan view are projected. A second pole stopper 56 is provided on the upper surface of the bracket 45 so as to project upward. Further, a second hook stopper 57 projects upward from the outer edge of the bracket 45.

  The pivot shaft 51 is rotatably fitted with a pivot hole 61 formed in a hook (emergency lock mechanism) 60 and directed in the vertical direction. The hook 60 is formed with a normal engagement groove 63 and an emergency engagement groove (emergency lock mechanism) 64 that are parallel and linear to each other. The normal engagement groove 63 is a groove that can be engaged with and disengaged from the full-open striker 25 and the intermediate striker 26, and the emergency engagement groove 64 is a groove that can be engaged and disengaged only with the full-open striker 25. At the periphery of the hook 60, a stopper surface 65 that can come in contact with and separate from the second hook stopper 57 and a stopper surface 66 that can come in contact with and separate from the first hook stopper 47 are formed. Further, an arc surface 67 and an engagement surface 69 are formed on the peripheral surface of the hook 60 in an arc shape centering on the pivot shaft 51 in plan view. In the vicinity of the circular arc surface 67 on the upper surface of the hook 60, a cylindrical engagement pin 68 is provided so as to face in the vertical direction. The hook 60 is rotatable between a lock release position where the stopper surface 65 contacts the second hook stopper 57 and a lock position where the stopper surface 66 contacts the first hook stopper 47. Further, a torsion coil spring (biasing means) S1 shown in FIG. 2 is wound around the pivot shaft 51, and one end of the torsion coil spring S1 is engaged with the bracket 45 and the other end is engaged with the hook 60. As a result, the hook 60 is always urged to rotate toward the unlocking position by the torsion coil spring S1.

  A pivot hole 76 of a pole 75 is rotatably fitted to the pivot shaft 50 of the fixed substrate 42. One end of the pole 75 is provided with an engaging projection 77 that can be engaged with and disengaged from the arc surface 67 and the engaging surface 69 of the hook 60, and the other end is locked with one end of the operation wire W <b> 1. A portion 78 is formed. The operation wire W1 passes through the inside of the wire support case 80 fixed to the attachment piece 43, and the other end is linked to the inside handle 35 and the outside handle 36 of the slide door 30. A peripheral surface of the pole 75 is formed with a stopper surface 81 that can contact and separate from the second pole stopper 56 and a stopper surface 82 that can contact and separate from the first pole stopper 54. The pole 75 is rotatable between a non-engagement position where the stopper surface 81 contacts the second pole stopper 56 and an engagement position where the stopper surface 82 contacts the first pole stopper 54. If the pole 75 is located in the engagement position when the hook 60 is in the locked position, the engagement protrusion 77 of the pole 75 engages with the engagement surface 69 of the hook 60, so that the hook 60 rotates the torsion coil spring S1. It is held in the locked position against the urging force. Further, in FIG. 2, the torsion coil spring (biasing means) S <b> 2 is wound around the pivot shaft 50, one end of which is locked to the bracket 45, and the other end is locked to the pole 75. Is always urged to rotate toward the engagement position by the torsion coil spring S2.

  A pivot attachment hole 91 of a switching lever (hook control mechanism) 90 is rotatably engaged with the pivot attachment shaft 52 of the bracket 45. On the peripheral surface of the switching lever 90, there are a pressing surface 92 that can be brought into and out of contact with the peripheral surface of the engaging pin 68 of the hook 60, a stopper surface 93 located at the end opposite to the pressing surface 92, and a switching lever stopper. A stopper surface 94 that can come into contact with and separate from the surface 49 is formed. The switching lever 90 is rotatable between the operating position shown in FIGS. 5 to 8 and the non-operating position shown in FIGS. 3 and 4. When the pawl 75 is in the non-engagement position (when the pawl 75 and the hook 60 are in the non-engagement state), when the switching lever 90 is rotated to the operating position, the pressing surface 92 is moved to the engagement pin 68 of the hook 60. , And the hook 60 rotates to the engageable position shown in FIGS. On the other hand, when the switching lever 90 rotates to the non-operating position when the pawl 75 is in the non-engaging position (when the pawl 75 and the hook 60 are in the non-engaging state), the pressing surface 92 moves from the engaging pin 68. Since it leaves | separates, the hook 60 rotates to a lock release position by the rotation urging | biasing of the torsion coil spring S1. Further, since the torsion coil spring S3 shown in FIG. 2 is wound around the pivot shaft 52, one end of the torsion coil spring S3 is locked to the interlocking lever 95, and the other end is locked to the switching lever 90. The switching lever 90 is always urged to rotate toward the operating position by the torsion coil spring S3. The rotational biasing force of the torsion coil spring S3 is stronger than the rotational biasing force of the torsion coil spring S1.

  Further, a pivot attachment hole 96 of an interlocking lever (hook control mechanism) 95 positioned above the switching lever 90 is rotatably fitted to the pivot attachment shaft 52. The interlocking lever 95 is provided with a stopper 97 that can be brought into contact with and separated from the interlocking lever stopper surface 48 and a mounting piece 98 that can be brought into and out of contact with the stopper surface 93 of the switching lever 90. The interlocking lever 95 is rotatable between the non-operation position shown in FIGS. 3 and 4 where the stopper 97 contacts the interlocking lever stopper surface 48 and the operation position shown in FIGS. Further, since the torsion coil spring S4 shown in FIG. 2 is wound around the pivot shaft 52, one end of the torsion coil spring S4 is locked to the bracket 45 and the other end is locked to the interlocking lever 95. The lever 95 is always urged to rotate to the inoperative position side by the torsion coil spring S4. The attachment piece 98 of the interlocking lever 95 and the stopper surface 93 of the switching lever 90 can be contacted and separated. Further, the rotational biasing force of the torsion coil spring S4 is stronger than the rotational biasing force of the torsion coil spring S3. 98 rotates the switching lever 90 to its inoperative position. One end of an operation wire (hook control mechanism) W2 is locked to the attachment piece 98, and the operation wire W2 passes through the inside of the wire support case 100 fixed to the attachment piece 55, and the other end of the operation wire W2. Is connected to the window regulator. When the window glass 33 moves downward from the fully closed position to a predetermined position on the fully open position side (when the opening of the window hole 31 reaches a predetermined opening), the operation wire W2 is pulled in conjunction with the operation of the window regulator. As a result, the interlocking lever 95 rotates to the operating position (the position shown in FIGS. 5 to 8). Then, the switching lever 90 is rotated to the operating position where the stopper surface 94 abuts against the switching lever stopper surface 49 by the rotational biasing force of the torsion coil spring S3. Further, since the rotational urging force of the torsion coil spring S3 is stronger than the rotational urging force of the torsion coil spring S1, if the pole 75 is in the disengaged position (if the pole 75 and the hook 60 are in the disengaged state), the pressing force The surface 92 presses the engagement pin 68 and the hook 60 rotates to the engageable position. On the other hand, when the window glass 33 is moved from the predetermined position to the fully closed position side in a state where the hook 60 is located at the engageable position (a state where the opening degree of the window glass 33 is equal to or larger than the predetermined opening degree) (window glass). When the opening 33 is smaller than the predetermined opening), the operation wire W2 is relaxed, and the interlocking lever 95 and the switching lever 90 are moved to the non-operating position by the rotational biasing force of the torsion coil spring S4.

Next, the operation of the above sliding door device will be described.
If the sliding door 30 is in the fully closed position and the inside handle and outside handle are not operated, the hook of the locking device 200 locks the full closing striker 27, and the sliding door 30 is held in the fully closed position. The When the inside handle 35 or the outside handle 36 is rotated to the open position side in this state, the hook of the lock device 200 releases the full-close striker 27, so that the slide door 30 can be slid to the full open position side (rear). Become.

Thus, the lock device 40 functions when the slide door 30 is slidable to the fully open position. However, since the operation of the lock device 40 changes depending on the state of the window glass 33, the state of the window glass 33 is changed to 2. The explanation is divided into streets.
(When the window glass 33 is on the fully closed position side (upper side) from the predetermined position)
First, the case where the window glass 33 is on the fully closed position side from the predetermined position will be described with reference to FIGS. 3 and 4.
In this case, since the switching lever 90 and the interlocking lever 95 are located at the non-operating position, the hook is located at the unlocking position as shown in FIG. Accordingly, when the slide door 30 is slid to the fully open position, the hook 60 does not contact the intermediate striker 26 and the slide door 30 slides to the fully open position even if the locking device 40 moves to the side of the intermediate striker 26. . When the slide door 30 reaches the fully open position, the full-open striker 25 is engaged with the normal engagement groove 63 of the hook 60 as shown in FIG. 3, and the hook 60 is twisted as shown in FIG. Rotate to the locked position against the rotational biasing force. When the hook 60 is rotated to the locked position, the inside handle 35 and the outside handle 36 are returned to the initial positions, so that the engaging protrusion 77 of the pole 75 that is urged to rotate toward the engaging position by the torsion coil spring S2. Engages with the engagement surface 69 of the hook 60. Accordingly, the hook 60 is held in the locked position, and as a result, the slide door 30 is held in the fully open position.
(When the window glass 33 is on the fully open position side (lower side, including the predetermined position; the same applies hereinafter) from the predetermined position)
Next, the case where the window glass 33 is on the fully open position side with respect to the predetermined position will be described with reference to FIGS. 5 and 6.
When the window glass 33 is on the fully open position side (lower side) from the predetermined position, as shown in FIG. 5, the switching lever 90 and the interlocking lever 95 are positioned at the operating position, so that the hook is positioned at the engageable position. To do. Therefore, when the slide door 30 is slid to the fully open position side and the locking device 40 reaches the side of the intermediate striker 26, the intermediate striker 26 is engaged with the normal engagement groove 63 of the hook 60 in the engageable position. To do. Further, as shown in FIG. 6, the hook 60 rotates to the locked position against the rotational biasing force of the torsion coil spring S1. Then, since the inside handle 35 and the outside handle 36 have returned to the initial positions, the engagement protrusion 77 of the pole 75 that is urged to rotate toward the engagement position by the torsion coil spring S2 is the engagement surface of the hook 60. 69, the hook 60 is held in the locked position, and the slide door 30 is held in the intermediate position. Thus, when the window glass 33 is on the fully open position side (lower side) from the predetermined position, there is a possibility that the occupant has put his hand or head in the opening of the window hole 31, but the slide door 30 is It is safe because it does not move to the fully open position and stops at an intermediate position.
When the window glass 33 is moved from the predetermined position to the fully open position side (lower side) due to a manufacturing error of the window regulator, a manufacturing error of the length of the operation wire W2, or a wiring mode of the operation wire W2. The interlocking lever 95 may rotate in the clockwise direction from the position shown in FIGS. In this case, the switching lever 90 that is rotationally biased by the torsion coil spring S3 rotates only to the operating position where the stopper surface 94 abuts against the switching lever stopper surface 49 of the stopper portion 46, but the interlocking lever 95 is illustrated in FIG. 5, the mounting piece 98 of the interlocking lever 95 and the stopper surface 93 of the switching lever 90 are separated from each other. Thus, even if the interlocking lever 95 rotates excessively in the clockwise direction, the switching lever 90 stops at the operating position, so that the hook 60 is positioned at the engageable position. Accordingly, the intermediate striker 26 is reliably engaged with the normal engagement groove 63 of the hook 60.

Next, in a state in which the window glass 33 is located on the fully closed position side (upper side) from the predetermined position, the slide door 30 moves from the fully closed position to the fully open position side, and the slide door 30 moves to the intermediate position (of the lock device 40). When the occupant moves the window glass 33 from the predetermined position to the fully open position side (lower side) by operating the door switch after the hook 60 exceeds the position where the hook 60 is positioned beside the intermediate striker 26), This will be described with reference to FIGS.
In this case, after the sliding door 30 exceeds the intermediate position, the hook 60 moves to the engageable position in conjunction with the operation of the window regulator (see FIG. 7), so that the sliding door 30 reaches the fully open position. However, the full-open striker 25 cannot be engaged with the normal engagement groove 63 of the hook 60. However, in this case, when the slide door 30 reaches the fully open position, the fully open striker 25 is engaged with the emergency engagement groove 64 of the hook 60 as shown in FIG. Therefore, as shown in FIG. 8, the hook 60 is rotated to the locked position against the rotational biasing force of the torsion coil spring S1 by the full-open striker 25. Then, the engaging protrusion 77 of the pole 75 that is rotationally biased toward the engaging position by the torsion coil spring S2 engages with the engaging surface 69 of the hook 60, so that the hook 60 is held in the locked position. As a result, the slide door 30 is held in the fully open position.

Finally, an operation when the slide door 30 located at the fully open position is slid to the fully closed position side (front side) will be described. Also in this case, the subsequent operation of the locking device 40 changes depending on the state of the window glass 33, and the state of the window glass 33 at this time will be described in two ways.
(When the window glass 33 is on the fully closed position side (upper side) from the predetermined position)
By operating the inside handle or the outside handle to rotate the pole 75 to the non-engagement position, the hook 60 can be rotated to the unlocking position side, so that the normal engagement groove 63 or the emergency engagement groove The fully open striker 25 can escape from 64, and the slide door 30 can slide forward. Even if the sliding door 30 slides forward and the locking device 40 reaches the side of the intermediate striker 26, the hook 60 is positioned at the unlocking position as shown in FIG. There is no contact with the striker 26 (see the phantom line in FIG. 3), and the sliding door 30 slides smoothly to the fully closed position. When the slide door 30 reaches the fully closed position, the hook of the locking device 200 locks the fully closed striker 27 as described above.
(When the window glass 33 is on the fully open position side (lower side) from the predetermined position)
On the other hand, in this case, since the hook 60 is located at the engageable position, as shown in FIG. 9, when the slide door 30 slides forward and the locking device 40 reaches the side of the intermediate striker 26, The intermediate striker 26 contacts the stopper surface 66 of 60. Then, when the hook 60 is rotated counterclockwise in FIG. 9 by the intermediate striker 26, the hook 60 gets over the intermediate striker 26, and the engagement pin 68 twists the pressing surface 92 of the switching lever 90 to produce a coil spring S3. The switching lever 90 rotates counterclockwise in FIG. 9, and the stopper surface 93 is separated from the mounting piece 98. When the hook 60 completely passes (passes) the intermediate striker 26, the switching lever 90 rotates clockwise by the rotational biasing force of the torsion coil spring S3, and the stopper surface 92 presses the engaging pin 68. Returns to the engageable position. When the sliding door 30 slides to the fully closed position, the hook of the locking device 200 locks the fully closing striker 27 as described above.

  As described above, according to the present embodiment, the sliding door 30 moves from the fully closed position to the fully opened position side in a state where the window glass 33 is located on the fully closed position side (upper side) from the predetermined position, and the sliding door After 30 exceeds the intermediate position (the position where the hook 60 of the locking device 40 engages with the intermediate striker 26), the occupant operates the door switch to move the window glass 33 from the predetermined position to the fully open position side (lower side). ), The emergency engagement groove 64 formed in the hook 60 grips the full-open striker 25, so that the slide door 30 can be held in the full-open position. Therefore, it is possible to prevent the slide door 30 from bouncing back against the rear wall of the door opening 21.
