Description

  The present invention relates to a cover structure of a swing slide door that opens and closes an entrance / exit provided on a side wall of a vehicle, and more particularly to a cover structure that covers an upper portion of a space between a swing slide door and a vehicle body.

  The swing slide door installed in the vehicle can swing so as to protrude outward from the state in which the entrance / exit is closed, and then slide backward to open / close the entrance / exit. Such a swing slide door is supported by a swing slide unit RU. For example, as shown in FIG. 13, a base 110 of a parallel link 101 is attached in the vicinity of the entrance / exit of the cab floor 100 which is a vehicle body base, A slide rail 130 and a slider (not shown) are slidably attached to the inner wall surface of the swing slide door 120, and a pair of front and rear arms 150, 160 are connected to the slider on the swing end side and the base 110 on the vehicle body base side. Each of the pins is coupled so as to be horizontally pivotable via the door, thereby restricting the position of the door. Further, the door load support is such that a pair of support arms 170 and 180, which are pin-coupled so as to be pivotable in the horizontal direction, are connected to each other by pin connection between the position near the center of gravity of the door 120 and the base 110. Arm 190 is equipped.

Examples thereof are disclosed in Japanese Patent Application Laid-Open No. 2003-320964 (Patent Document 1) and Japanese Patent Application Laid-Open No. 10-175444 (Patent Document 2).
In this way, the swing slide door 120 is held at the swing position that protrudes out of the vehicle from the closed position or at the fully open position that slides backward. At this time, a swing slide unit RU including a parallel link 101 and a door load support arm 190 which are driven to form a mode corresponding to an open / close state of the door is disposed in a space between the door and the outer wall surface of the vehicle body. For this reason, from the standpoint of maintaining aesthetics, the door or the occupant's hand or the like that descends from above the space is prevented from entering and directly contacting the space that houses the swing slide unit RU during the door opening / closing operation. For example, it is considered that the parallel link 101 and the door load support arm 190 are covered with a bellows-like covering member (not shown).

  Alternatively, as shown in FIG. 14, one end 221 of a flexible thin plate member 220 is integrally coupled to the base portion 210 of the swing slide unit RU supported on the vehicle body side, and the other end 222 forms a door inner wall surface. It inserts in the accommodation space 224 provided in 223 so that insertion / extraction is possible. Thereby, it is possible to cover the space 226 between the base 210 on the vehicle body side and the door trim 223 on the door side (not shown) from above.

An inclined extending portion 15b and a fastening flange 15c that is bent and extended from the downward inclined extending portion 15b and is bolted to the forward stepped portion 601 forming a part of the mounting recess T are provided.

The upper vertical column portion 152 welds a base end boss portion 41 that pivotally supports the base end of the door load support arm 18 via the vertical pin 43 so that the base end boss portion 41 is covered with the U-shaped fastening bracket 53. And are welded to each other. Further, the U-shaped fastening bracket 53 has a vertical wall surface extending away from the base end overlapped with the mounting recess T on the vehicle body side, and both members are bolted.
The U-shaped fastening bracket 53 that constitutes the main part of the base member 15 is vertically moved to the upper and lower flanges Ju, Jd (only the upper side is shown in FIGS. 4 and 5) that is the front end (right side in FIG. 5). The base ends of the bent pieces 94 and 95 (see FIG. 5) are integrally joined. As shown in the drawing, the pivotally supported end portion (base end portion) of the vertical plate-shaped link cover 96 is pivotally attached to the vertically extending ends of the vertically bent pieces 94 so as to be swingable around the rotation center line Lc. .

Further, as shown in FIGS. 3, 4, and 7, an upper cover cover 71 is pivotally attached to the upper flange Ju of the U-shaped fastening bracket 53 via a cover mounting bracket 70.
As shown in FIGS. 4 and 5, the link cover 96 includes a plate-like main portion 961 and upper and lower bent flanges 963 and 964.
As shown in FIGS. 5 and 6, the main portion 961 of the link cover 96 is opposed to the load support arm 18 and has a facing surface that can come into contact with the swing end m of the arm cover 91 pivotally supported by the trim 80. The
The link cover 96 is formed so that the base end side of the upper and lower flanges 963 (only the upper flange is shown in FIG. 5) is opposed to the upper and lower extension ends of the upper and lower bent pieces 94 and 95 (see FIG. 5). Are connected by fasteners c1 and c2 so as to be rotatable around the rotation center line Lc. In addition, the link cover 96 is pivotally biased toward a door load support arm 18 and a parallel link 16 (to be described later) by a coil spring (not shown), and abuts against any one of those portions.

As shown in FIGS. 7 and 8, the cover mounting bracket 70 fastened to the upper flange Ju of the U-shaped fastening bracket 53 with a bolt (not shown) includes a main part 702 extending above the fastening part 701, and a main part 702. The position restricting portion 703 is formed so as to protrude in the vehicle outward direction to restrict the lateral position P0, and the position restricting portion 704 is formed so as to protrude above the main portion 702 and restrict the longitudinal position P1. And a hinge 705 welded to a root portion of the position restricting portion 703 with respect to the main portion 702. In a state where the fastening portion 701 is fastened to the upper flange Ju with a bolt (not shown), the hinge 705 pivotally supports the base portion of the upper surface hidden cover 71 so as to swing around the central axis Lk that extends in the same direction as the vehicle body longitudinal direction X. ing.
Here, since the cover mounting bracket 70 is configured to be provided with a hinge 705, the height h1 between the hinge 705 on the position restricting portion 703 above the fastening portion 701 can be set relatively easily, The degree of freedom for setting the position of the center axis Lk of the base of the upper surface hidden cover 71 is increased.

The upper surface hidden cover 71 is relatively thick and is formed in a substantially rectangular shape as a rigid resin plate. In particular, as shown in FIGS. 4 and 6, when the parallel link 16 and the door load support arm 18 protrude in the vehicle exterior direction when held in the lateral position P0, It is formed to take a shape that covers the upper side of the space E <b> 1 between the inner wall surface of the rear door 4.
Here, when the upper surface hidden cover 71 is in contact with the position restricting portion 703 by its own weight and holds the lateral position P0, a predetermined gap is formed between the inner wall surface of the rear door 4 at a position facing the rotation end of the upper surface hidden cover 71. Opposed through t. In this case, the rear door 4 is relatively moved between the swing position D2 and the fully open position D3, but is formed so as not to interfere with each other.

  Further, when the rear door 4 moves from the swinging position D2 to the closing position D1, the rotation end of the upper surface hidden cover 71 comes into contact with the inner wall surface of the rear door 4 and receives a pressing force from the inner wall surface of the rear door 4, and FIG. The upward swing is started from this state. At the start of the upward swing, a projection 77 described later on the link cover 96 rotates the upper surface hidden cover 71 upward by a predetermined amount and simultaneously receives a pressing force from the inner wall surface of the rear door 4. Smooth upward rotation can be started.

  Further, when the inclination angle α is gradually increased as shown in FIGS. 9C and 9B and the rear door 4 reaches the closed position D1, it reaches the vertical position P1 as shown in FIG. 9A. At this time, the upper surface hidden cover 71 is held in an almost upright state by contacting the position restricting portion 704 that restricts the vertical position P1.

Thus, the upper surface hidden cover 71 is held almost upright, so that the upper surface hidden cover 71 is held in the gap between the inner wall surface of the rear door 4 and the vehicle exterior opening of the mounting recess T, and the rear door Since 4 is closed, the contact / separation operation to the closed position D1 is not hindered.
Here, as shown in FIGS. 4 and 5, a vertical plate-shaped link cover 96 is pivotally attached to the front end portion of the U-shaped fastening bracket 53 so as to be slidable around the rotation center line Lc. A push-up member 76 is welded to the upper flange 963 of the link cover 96. The push-up member 76 has a protrusion 77 that pushes up the lower surface in the vicinity of the central axis Lk of the base of the upper cover cover 71 when the link member 96 rotates together with the link cover 96 around the rotation center line Lc.

Here, as shown in FIG. 4, the link cover 96 at the fully open position D3 is in a position indicated by a two-dot chain line, and at that time, the protrusion 77 is at the position a1 and in the vicinity of the upper surface hidden cover 71. . Accordingly, when the link cover 96 is swung clockwise around the central axis Lk in FIG. 4 by the parallel link 16 or the like, the protrusion 77 is swung to the position a2. At this time, the inclined surface of the protrusion 77 pushes up the lower surface near the central axis Lk of the base of the upper surface hidden cover 71, and the upper surface hidden cover 71 is pressed as shown in FIG. Can start.
As shown in FIGS. 4 and 10, a parallel link 16 having a function of positioning each position of the sliding and sliding rear door 4 is provided on the U-shaped fastening bracket 53 that constitutes a main part of the base member 15. The parallel link 16 includes a front arm 31 and a rear arm 32.

  As shown in FIGS. 10 to 12, the base end of the front arm 31 is pivoted horizontally to the front portion of the lateral flange portion 15a having upper and lower double walls via a vertical pin 26f (see FIG. 3). The base end of the rear arm 32 includes a base end boss 321, and the base end boss is pivotally supported by the lower extension of the vertical pin 43 supported by the upper vertical column portion 152. For this reason, the rear arm 32 and the door load support arm 18 rotate around a common rotation center line Lar (see FIG. 8).

As shown in FIGS. 4 and 5, the swinging ends of the front arm 31 and the rear arm 32 are fitted to a door support rail 22 that is integrally coupled to an inner panel 402 of the rear door 4 via a mounting bracket 35. Here, the mounting bracket 35 is a bent plate material shaped so as to cover the central main portion of the inner wall of the inner panel 402, and a door-side pivot portion 37 (to be described later) is integrally mounted near the center of gravity of the door.
The door support rail 22 is fitted to the upper and lower downward rail grooves 33u and 33l of the door support rail 22 formed in the longitudinal direction X through the front and rear rollers 23f and 23r so as to be slidable in the front and rear direction.

Here, the front arm 31 and the rear arm 32 can be swung while maintaining a predetermined interval in the front-rear and up-down directions, and are formed so as to prevent mutual interference between both arms. The vicinity of each oscillating end of the front arm 31 and the rear arm 32 is pin-coupled to the front and rear ends of the slider 24 (see the broken line in FIG. 10), respectively, so that the relative distance is maintained at a predetermined value.
As shown in FIGS. 2 and 5, the outer panel 401 of the rear door 4 and the inner panel 402 arranged via the door interior space are integrally joined to each other at the front and rear and lower outer peripheral edges. An opening is formed in the upper peripheral edge of the panel. The opening is formed so that a lifting / lowering operation area of a door glass (not shown) and a sash 55 of the supporting member can be mounted.

In addition to the door glass, an opening / closing drive mechanism 19 (see FIG. 10), a wire harness W, and a controller 30 as control means are mounted in the interior space of the door. 10, the controller 30 is connected to the power source (not shown) on the vehicle body side and the main controller 300 by a wire harness W.
A vehicle interior side surface of the inner panel 402 of the rear door 4 is covered with a trim 80. As shown in FIGS. 2 and 3, the trim 80 has a slit 81 for inserting the front and rear arms 31, 32 of the parallel link 16 formed long in the front-rear direction X so that the upper half 80 u and the lower half 80 d are divided. The whole is locked to the inner panel 402 side by locking means (not shown) with respect to the entire inner side surface of the inner panel 402.

  As shown in FIGS. 2 and 3, a mounting hole 90 into which the door side pivotal support portion 37 is fitted is formed in the center of the upper half portion 80 u of the trim 80. Here, the door-side pivot portion 37 is integral with the door-side inner panel 402 and is pin-coupled to a door load support arm 18 side described later. The mounting hole 90 is formed in a horizontally long rectangular hole so that the peripheral edge of the mounting hole 90 in the upper half 80u does not interfere with the second swing arm 61 and the first swing arm 44 described later.

  Further, a base end portion 911 of a long plate-like arm cover 91 that swings is pivotally mounted in the vicinity of the periphery of the mounting hole 90 of the upper half 80u on the front side of the vehicle body. The main portion 912 extending from the base end portion 911 via the hinge portion 913 has a long plate shape so as to cover the second swing arm 61 and the door side pivot portion 37 that are partially fitted into the mounting hole 90 when the door is closed. It is formed in a simple shape. The arm cover 91 is formed in a thick plate shape, and the hinge portion 913 is formed as a thin-film resin hinge. A base end of a coil spring (not shown) is locked to the base portion 911, a movable end of the coil spring is locked to the main portion 912, and the main portion 912 of the arm cover 91 is connected to the vehicle body front facing surface Ff of the second swing arm 61. It is urged to rotate so as to abut in the direction.

For this reason, it is possible to cover the vehicle body front facing surface Ff of the arm cover 91 in a state where the main portion 912 of the arm cover 91 follows at least the movement of the second peristaltic arm 61, and that the occupant directly contacts the door load support arm. Can be prevented, safety is improved, and aesthetics can be improved.
Further, a horizontally long convex portion 92 is continuously formed over the upper peripheral edge of the mounting hole 90 and the front and rear extension portions thereof, thereby blocking the line of sight from the vehicle heading toward the mounting hole 90 and the second swing arm 61 when the door is closed. We are trying to secure it.
As shown in FIGS. 4 and 10, a door load support arm 18 is attached above the parallel link 16.

  The door load support arm 18 has a base end of the first support arm 44 via a first vertical pin 43 on a base end boss portion 41 formed on an upper vertical column portion 152 on an upper portion of the base member 15 pivotally supported on the vehicle body side. Part 441 is pivotally supported. The base end portion 611 of the second support arm 61 is pivotally supported at the rotation end of the first support arm 44 via the second vertical pin 62, and the swing end 612, which is the other end, is near the center of gravity position of the rear door 4. The door side pivot portion 37 is pivotally supported via the third vertical pin 36.

  The first support arm 44 and the second support arm 61 constituting the door load support arm 18 are formed of a rigid material as a bar-shaped member having a vertically long cross section. As a result, the door load support arm 18 can be prevented from being deformed even when receiving a door load in the vertical direction, and the load at the center of gravity of the rear door 4 can always be transmitted to the base member 15. At this time, as shown in FIGS. 10 to 12, the door load support arm 18 reliably supports the door load of the rear door 4 at any position where it moves from the closed position D1 to the swing position D2 and the fully open position D3. The inclination of 4 can be regulated.

  The main part of the wire harness W is supported by such a door load support arm 18. That is, as shown by a two-dot chain line in FIG. 10, the wire harness W is an electrical device in the rear door 4, for example, an electric window regulator (not shown), power latches 6, 8 of the front and rear end lock portions J 1, J 2, J 3. Alternatively, the wiring harness W is formed by bundling each wiring of the latch sensor and the controller 30 (not shown), and the wire harness W is connected to the power source (not shown) on the vehicle body side and the main controller 300. Here, the wire harness W extends from the vehicle body side and is not attached to each side wall of the base end portion 441 of the door load support arm 18, the first support arm 44, the second support arm 61, the swing end 612, and the door side pivot support portion 37. The clips are sequentially fastened using clips formed of the illustrated resin, etc., reach the inner space side of the rear door 4, and are connected to a controller 30 or the like that is a control device.

Next, as shown in FIGS. 4, 5, and 10, the door support rail 22 is formed with an upper downward main, secondary rail grooves 33 u 1 and 33 u 2, a lower main downward rail groove 33 l 1, and a downward upward rail groove 33 l 2. A slider 24 is slidably inserted into the inside via a plurality of rollers r.
The slider 24 has a plate-like substrate 241 that is long in the front-rear direction X, a pair of vertically long walls 242 and 243 that are long in the front-rear direction X projecting from the upper surface of the substrate, and a downward projection from the downward wall behind the substrate 241. And a rear connecting pin 245 that is pin-coupled to the swinging end of the rear arm 32, a columnar downward projecting portion 244 that extends downward from a downward wall from the front of the substrate 241, and a downward projecting portion from the downward projecting portion 244. A front connecting pin 246 that is provided and is provided with a rocking end of the front arm 31 and a pin connection.

  Here, the rear connection pin 245 and the pivot pin of the rear roller 23r are disposed on the same center line Lrr, and the front connection pin 246 and the pivot pin of the front roller 23f are disposed on the same center line Lrf. The front and rear rollers 23f and 23r slidable along the downward and downward rail grooves 33u1 and 3311 of the support rail 22 have a configuration in which they are also arranged at the outer swing center points prf and prr (see FIG. 10) of the parallel links. The peristaltic displacement of the parallel link 16 is facilitated.

  Here, the downward rail grooves 33u1 and 33u2 above the door support rail 22 are formed long in the front-rear direction X. On the other hand, as shown in FIG. 10, the lower main downward rail groove 3311 and the lower upward rail groove 33l2 are formed up to substantially the middle part in the longitudinal direction of the door support rail 22, and are formed at the rear (left side in FIG. 10). It has not been. The lower main downward rail groove 33l1 and the lower upward rail groove 33l2 are fitted with the front roller 23f at the sliding end of the front arm 31 fitted therein and the front roller 23fs in the vicinity thereof. In particular, the front roller 23f abuts against the stopper wall portion rs0 of the lower main downward rail groove 3311 to prevent further forward sliding of the relative door support rail 22 (rear door 4). The swing position D2 of the rear door 4) is regulated.

  Therefore, when the front arm 31 swings around the front arm swing base point pcf, that is, when the front arm 31 swings relatively around the center line of the front roller 23f at the swing position D2 (around the outer swing center point prf), The side of the front roller 23fs near the front roller 23f rotates so as to draw an arc (see an arrow of a two-point difference line in FIG. 10) q1 around the center line of the front roller 23f. In this state, the previous roller 23fs is displaced while maintaining a roller contact state outside the stopper wall portion rs0, and the center line of the front roller 23f can be prevented from shifting in the front-rear direction X. By relatively swinging the front arm 31 around the center line of the front roller 23f, the door support rail 22 (rear door 4) can swing from the swing position D2 to the closed position D1 shown in FIG. At this time, the preceding roller 23fs reaches the deepest curved portion of the upward-facing rail groove 3312 as shown in FIG.

  On the other hand, the front arm 31 swings around the front arm swing base point pcf, the front roller 23f contacts the stopper wall rs0 of the main downward rail groove 3311, and the door support rail 22 (rear door 4) reaches the swing position D2. When the support rail 22 (rear door 4) slides rearward toward the fully open position D3, as shown in FIG. 10, the adjacent previous roller 23fs faces the straight portion from the curved portion of the upward-facing rail groove 3312. The front roller 23f and the front roller 23fs smoothly slide relative to each other along the main downward rail groove 33l1 and the subordinate upward rail groove 33l2, and as shown in FIG. 11, the door support rail 22 (rear door 4) is fully opened. It can be moved to D3.

The parallel link 16 connects the slider 24 fitted to the door support rail 22 of the rear door 4 and the base member 15, so that the middle portion of both arms is provided in the front-rear direction provided in the trim 80 as shown in FIG. X is inserted into a long slit 81. The upper opening portion of the slit 81 is covered with an upper lip 82 made of an elastic material that interferes with the rear arm 32, and the lower opening portion is covered with a lower lip 83 made of an elastic material that interferes with the front arm 31.
Next, the rear door 4 is provided with an opening / closing drive mechanism 19 (see FIG. 10).

  As shown in FIGS. 1 and 10 to 12, the opening / closing drive mechanism 19 has a function of moving the rear door 4 from the closed mounting position to the fully open position by the rotational force of the motor 101 and the winding drum 46 that form the drive source. In other words, the opening / closing drive mechanism 19 includes a motor 101 disposed in the rear door 4, a winding drum 46 that is wound around the motor 101 and driven so as to be rewound, and an opening that is retractably wound around the winding drum 46. The operation cable 49 and the closing operation cable 51, the end pulley po1 at the front end of the door support rail 22 around which the opening operation cable 49 is wound, and the end pulley pc1 at the rear end of the door support rail 22 around which the closing operation cable 51 is wound up. , An open first pulley po2 on the front arm 31, a second pulley po3, a first pulley pc2 on the rear arm 32, a second pulley pc3, and an anchor of the open operation cable 49 pivotally supported by the lateral flange portion 15a. A cable end poe connected to each other, and a cable end pce connected to the anchor portion of the closed operation cable 51.

Next, the operation of the rear door 4 will be described.
It is assumed that the rear door 4 is held at the closed position D1 before the controller 30 receives the door opening command.
At that time, the power latches 6 and 8 of the front end upper lock portion J1, the front end lower lock portion J2 and the rear end lock portion J3 on the rear door 4 side are held in a non-energized state while holding the locked state.
In this case, as shown in FIG. 12, the swinging ends of the rear arm 32 and the front arm 31 are drawn into the vehicle interior, and the door support rail 22 together with the slider 24 of the swinging ends of both arms closes the rear door 4 shown in FIG. (Refer FIG. 1) The state which hold | maintains D1 is maintained.

In the state in which the rear door 4 holds the closed position D1, as shown in FIG. 7A, the link cover 96 abuts against the parallel link 16 and rotates largely forward, and the arm cover 91 has a swing end m at the first end. The two swing arms 61 abut against the front-facing surface Ff of the vehicle body and rotate backward.
In this case, the link cover 96 and the arm cover 91 are overlapped closest to the trim side and are fitted below the horizontally long convex portion 92 so that the parallel link 16 and the door load support arm 18 are completely line of sight of the passenger in the vehicle. Covered from.
Further, as shown in FIG. 9A, the upper surface hidden cover 71 is held almost upright, so that the upper surface hidden cover 71 is pressed against the end of the trim 80 of the rear door 4 and the vehicle exterior opening of the mounting recess T is provided. It is held in a state of being sandwiched in the gap between the two and is disposed outside the vehicle, so that it does not protrude into the vehicle and does not impair the beauty.

Next, when the controller 30 receives a door opening command, the power latches 6 and 8 of the front end upper lock portion J1, front end lower lock portion J2 and rear end lock portion J3 of the rear door 4 at the closed position D1 are connected via the wire harness W. The lock release output is issued.
Next, the motor 101 of the drive source M is driven, and the cable end poe connecting the anchor portion of the open operation cable 49 and the fixed pulley po1 on the door support rail 22 as shown by a thick two-dotted line in FIG. A cable stretched between them is taken up by an open winding portion (not shown) of the winding drum 46. At this time, the loose side of the closing operation cable 51 is rewound to a closed winding portion (not shown).

As a result, the front arm 31 and the rear arm 32 interlocked therewith are oscillated and displaced from the closed position D1 to the oscillating position D2 shown in FIG. At this time, the front arm 31 swings around the front arm swing base point pcf, and the front roller 23f at the swing end of the front arm 31 is kept in contact with the stopper wall portion rs0 of the lower main downward rail groove 3311. Since the previous roller 23fs in the vicinity of the front roller 23f maintains the roller contact state outside the stopper wall rs, the center line of the front roller 23f is prevented from shifting in the front-rear direction X, and the swinging displacement of the parallel link is reliably performed. Made.
The link cover 96 and the arm cover 91 are swung following the parallel link 16 and the door load supporting arm 18 until the rear door 4 holds the swing position D2, and the link cover 96 is swung as shown in FIG. By maintaining a state where the vicinity of the end and the swing end m of the arm cover 91 overlap each other, these function as partition walls.

  In particular, as the rear door 4 moves toward the swing position D2, the state is sequentially displaced in the states of FIGS. 9B, 9C, and 9D, that is, the swing end of the upper surface hidden cover 71 is within the trim 80. It fluctuates in the horizontal direction due to its own weight while sliding on the wall surface. When the rear door 4 reaches the swing position D2, the upper surface hidden cover 71 contacts the position restricting portion 703 and is securely held at the lateral position P0, and the parallel link 16 and the door load support arm 18 below the space E1. Is covered from above. At this time, the upper cover cover 71 having high rigidity can function as a partition on the upper side with respect to the door load support arm 18 and the parallel link 16, and the occupant's safety can be reliably maintained, and the occupant's downward eyes can be seen. The door load support arm 18 and the parallel link 16 side can be covered and function to maintain the aesthetic appearance.

Next, by the action of the opening / closing drive mechanism 19 and the wire harness W, the rear door 4 passes through the swing position D2, and the door support rail is relative to the slider 24 at the swing end of the parallel link 16 where the swing is stopped. Assume that the 22 side is slid to the fully open position D3 shown in FIG.
Here, the link cover 96 and the arm cover 91 are swung following the door load support arm 18 until the rear door 4 holds the fully open position D3. In this state, as shown in FIG. 6C, the link cover 96 is in contact with the parallel link 16, and the base end of the arm cover 91 is pressed by the second swing arm 61 and is sandwiched between the trims. Thus, the swing end m approaches the arm facing surface of the link cover 96 and faces the arm.

In this state, the gap between the front end portion of the rear door 4 at the fully open position D3 and the case member 15 on the vehicle body side is securely closed by the link cover 96, and this link cover 96 serves as a partition wall, so And the door load support arm 18 can be partitioned.
Further, while the rear door 4 is moved from the swing position D2 to the fully open position D3, a predetermined gap t is maintained between the swing end of the upper surface hidden cover 71 and the trim 80 of the rear door 4, so that a smooth fully open operation can be performed without mutual interference. Moreover, since the arm cover 91 and the link cover 96 cover the sides of the swing slide unit U and the upper surface is covered with the upper cover cover 71, the safety of the occupant is improved and the aesthetics can be further improved.

When the controller 30 receives a door closing command, the motor 101 as a driving source is driven to operate reversely to the states of FIG. 6B and FIG. 6A. It is made smoothly as well.
In particular, when the rear door 4 moves from the fully open position D3 to the swing position D2 and then moves from the swing position D2 to the closed position D1, the link cover 96 is in the position shown in FIG. 4, and the protrusion 77 is in the position a1. . Accordingly, when the link cover 96 is swung clockwise around the central axis Lk in FIG. 4, the protrusion 77 is swung to the position a <b> 2, and the inclined surface of the protrusion 77 near the center axis Lk of the upper surface hidden cover 71. The lower surface is pushed upward and pressed as shown in FIG. 9C to smoothly start the upward swing.

  Further, the sliding end of the upper surface hidden cover 71 comes into contact with the trim 80, receives a pressing force, and gradually increases the inclination angle α as shown in FIGS. 9C and 9B from the state of FIG. 9D. When the rear door 4 reaches the closed position D1, the vertical position P1 is reached as shown in FIG. 9 (a). At that time, the rear door 4 comes into contact with the position restricting portion 704 that restricts the vertical position P1, and the upper surface hidden cover 71 is contacted. Is held almost upright. As described above, the upper surface hidden cover 71 is held between the inner wall surface of the rear door 4 and the vehicle exterior opening of the mounting recess T, and the rear door 4 is closed, which may hinder the contact / separation operation to the closed position D1. Nor does it degrade the aesthetics.

In the above description, the upper surface hidden cover 71 covers the door load support arm and the upper space E1 of the parallel link 16. However, the upper surface is simply a relatively small size that covers only the parallel link 16 and facilitates mounting. A hidden cover 71 may be used. Furthermore, although the structure which covers the door load support arm and the front side of the parallel link 16 with the link cover 96 and the arm cover 91 has been disclosed, the arm cover 91 may be removed to simplify the structure.
The upper surface hidden cover 71 provided with the projections 77 as shown in FIG. 4 was attached at the initial stage of the upward rotation of the upper surface hidden cover 71. However, these may be excluded in some cases, and the shape of the inner wall surface of the trim 80 and the upper surface hidden The tilt angle of the cover 71 may be adjusted to facilitate the initial swinging of the upper cover cover 71 and to simplify the configuration.

  Even in the case of adopting such a configuration, the upper surface hidden cover covers the upper space of the space E1 between the vehicle body and the swing slide door, so that the occupant is prevented from directly contacting the parallel link. Yes, safety is improved and aesthetics can be improved.
