  In the slide door structure 10 of the present embodiment, a door trim 44 is provided inside the slide door 22. The door trim 44 is provided with an armrest 46 and a door pocket 48, and an end 46 </ b> A projecting inward in the vehicle width direction of the armrest 46 is formed on the entire sliding door side member positioned above the pair of link arms 16 and 18. Among them, it is the part that protrudes inward in the vehicle width direction.

  As shown in FIG. 4, the armrest 46 serves as an auxiliary closing member that closes the door-side opening 38 </ b> A between the shielding plates 30 and 32 when the slide door 22 is in the door opening / closing intermediate position. Yes. That is, as shown in FIG. 4, the armrest 46 overlaps with the door side opening 38 </ b> A between the shielding plates 30 and 32 when the slide door 22 is in the door open / closed intermediate position, so that the door side opening 38 </ b> A is obtained. It is configured to block.

  Further, in the slide door structure 10 of the present embodiment, the rocker portion 12 is provided with a scuff plate 50. A weather strip 52 is provided outside the scuff plate 50 in the vehicle width direction, and a projecting end portion 52A of the weather strip 52 outward in the vehicle width direction is a rocker portion located above the pair of link arms 16 and 18.

The vehicle body side opening 38B is closed.

  Next, the operation of the sliding door structure 10 having the above configuration will be described.

  As described above in detail, in the sliding door structure 10 according to the present embodiment, the shielding plates 30 and 32 have the opening 38 between the pair of link arms 16 and 18 as shown in FIGS. It is the structure which rocks | fluctuates interlockingly with a pair of link arms 16 and 18, closing. Therefore, according to this configuration, it is possible to sufficiently close the opening 38 between the link arms 16 and 18 when the link arms 16 and 18 swing.

  In the sliding door structure 10 according to the present embodiment, the shielding plates 30 and 32 are held by the pair of link arms 16 and 18 so as to swing integrally with the link arms 16 and 18. Therefore, the opening 38 between the link arms 16 and 18 can be reliably closed by the shielding plates 30 and 32 when the pair of link arms 16 and 18 swings with a simple configuration.

  In this type of sliding door structure 10, the shape (opening position and opening area) of the opening 38 between the link arms 16 and 18 changes as the link arms 16 and 18 swing. According to the above, it is possible to make the closed region by the shielding plates 30 and 32 follow the change in the shape of the opening 38 accompanying the swinging of the link arms 16 and 18. Thereby, it is possible to sufficiently close the opening 38 between the link arms 16 and 18 in the entire range of the door opening / closing locus of the slide door 22.

  Moreover, in the sliding door structure 10 which concerns on this embodiment, the shielding plates 30 and 32 are made into the structure of multiple sheets (in this embodiment, 2 sheets as an example). Therefore, by using a plurality of shielding plates 30 and 32, the degree of freedom of the shape of the shielding plates 30 and 32 is increased, and the followability to the change in the shape of the opening 38 accompanying the swinging of the link arms 16 and 18 is improved.

  In particular, for example, the bellows member can deal only with the expansion / contraction direction (that is, the movement is one-dimensional). According to the above configuration, it is possible to follow the expansion and contraction accompanying the swinging and the shape change caused by the movement in the link swinging direction). Further, when the bellows member is used, the appearance is poor and the durability is low, but according to the present embodiment, since the shielding plates 30 and 32 are used, the appearance is good and the durability is high.

  Further, in the sliding door structure 10 according to the present embodiment, by forming the two shielding plates 30 and 32, as shown in FIG. 4, the opening area of the opening 38 between the link arms 16 and 18 is maximized. It is also possible to ensure a large shielding area at the door opening / closing intermediate position.

  In the sliding door structure 10 according to the present embodiment, the shielding plates 30 and 32 are configured to maintain a state where they overlap each other in the vertical direction (overlapping vertically) when the pair of link arms 16 and 18 swings. Therefore, when the shielding plates 30 and 32 swing together with the pair of link arms 16 and 18, the edges (terminals) of the shielding plates 30 and 32 do not face each other. It is possible to prevent each other from being caught (in a butting state), and the relative sliding operation between the shielding plates 30 and 32 accompanying the swing of the pair of link arms 16 and 18 can be made smooth. As a result, the opening 38 between the link arms 16 and 18 can be reliably closed over the entire range of the door opening / closing locus of the slide door 22.

  In particular, as shown in FIG. 5, the opening area of the door opening 28 can be ensured (the pair of link arms 16, 18) by making two shielding plates 30 and 32 substantially overlap each other at the door fully open position. The opening 38 between the link arms 16 and 18 can be closed without hindering securing the swing angle to the rear of the vehicle. Further, since the opening area of the door opening 28 can be ensured to be large, the passenger can get on and off the third seat 56 behind the second seat 54.

  Further, as shown in FIG. 3, the two shielding plates 30 and 32 are configured so as to overlap each other even in the fully closed position of the door, thereby shielding the link arms 16 and 18 and between the hinge bases 14 and 24. The plates 30 and 32 can be stored compactly. Thereby, size reduction of the arrangement | positioning space of the slide door 22 and a vehicle body can be achieved. Further, since the shielding structure can be completed within the hinge assembly configured by the hinge bases 14 and 24 and the link arms 16 and 18, restrictions on the vehicle body side and the slide door 22 side can be reduced.

  Further, in the sliding door structure 10 according to the present embodiment, the sub arms 40 are provided on the pair of link arms 16 and 18. Therefore, as shown in FIG. 6, even when a downward load is applied to one of the link arms 16 and 18 via the shielding plates 30 and 32, the downward load is distributed to the other link arm 16 and 18 by the sub arm 40. Is done. Thereby, the deformation | transformation by the concentrated load of one link arm 16 and 18 and the deformation | transformation damage of the shielding plates 30 and 32 accompanying this can be prevented, and the obstruction | occlusion state of the opening 38 between link arms 16 and 18 can be maintained.

  In particular, in the present embodiment, the shielding plates 30 and 32 are cantilevered. However, as shown in FIG. 6, the sub-arm 40 can support the free end portions 30B and 32B. Even when a downward load is applied to the free ends 30B and 32B of the plates 30 and 32, the amount of deformation on the free ends 30B and 32B can be minimized.

  In the sliding door structure 10 according to the present embodiment, as shown in FIG. 4, the armrest 46 overlaps the door side opening 38 </ b> A between the shielding plates 30 and 32 in the vehicle plan view, thereby forming the door side opening 38 </ b> A. The scuff plate 50 and the weather strip 52 are configured to close the vehicle body side opening 38B by overlapping the vehicle body side opening 38B between the shielding plates 30 and 32 in plan view of the vehicle. Therefore, even if the door side opening 38A and the vehicle body side opening 38B are formed between the shielding plates 30 and 32 when the pair of link arms 16 and 18 are swung as in the present embodiment, the door side opening 38A and the vehicle body side opening 38B are closed by the armrest 46, the scuff plate 50, and the weather strip 52, respectively. Thereby, the obstruction | occlusion area with respect to the opening 38 between the link arms 16 and 18 can be expanded.

  Further, in the sliding door structure 10 according to the present embodiment, as shown in FIG. 5, the shielding plates 30 and 32 hardly project from the pair of link arms 16 and 18 when the door is fully opened. By providing, it can also prevent that boarding / alighting property is inhibited. Further, by closing the opening 38 between the link arms 16 and 18 with the shielding plates 30 and 32, the shielding plates 30 and 32 can be used as a step for getting on and off. Thereby, boarding / exiting property is also improved. In this case, if the surfaces of the shielding plates 30 and 32 are slip-prevented, it is possible to further improve boarding / exiting performance by preventing slipping during boarding / exiting.

  Next, a modification of this embodiment will be described.

  In the above-described embodiment, the two shielding plates 30 and 32 are configured, but two or more configurations may be used.
