Both side portions of the passenger compartment 11 are formed by body panels 13 constituting the vehicle body 2, and door openings 14 are opened in the body panel 13 on the left side of the rear seat 12. An entrance / exit step portion 14a is formed at the lower edge of the door opening 14.

  A seal surface 15 is formed on the body panel 13 on the outer periphery of the door opening 14. A bead 16 extending in the vertical direction and protruding outward in the vehicle width direction is formed on the lower side portion 15a of the seal surface 15. The bead 16 is formed below the front end of the step portion 14 a of the door opening 14, that is, at the front end of the lower side portion 15 a of the sealing surface 15. A storage portion 17 is provided below the corner portion 15b formed at the front end of the lower side portion 15a of the seal surface 15 so as to extend outward in the vehicle width direction. The storage portion 17 is curved backward as it goes outward in the vehicle width direction, and has an opening portion 17a that opens to the body panel 13, so that the front end of the slide rail 31 described later is stored and supported. Note that the upper edge of the opening 17a of the storage portion 17 is disposed on the outer side in the vehicle width direction than the lower edge.

  On the other hand, on the inner surface of the slide door 3, a weather strip 21 having a frame shape and having substantially the same cross section continuous in the longitudinal direction is provided. The weather strip 21 comes into contact with the sealing surface 15 when the slide door 3 is closed. That is, the lower side portion 21 a and the corner portion 21 b of the weather strip 21 come into contact with the lower side portion 15 a and the corner portion 15 b of the sealing surface 15. The slide mechanism 4 includes a slide rail 31 supported by the vehicle body 2 below the door opening 14 and an arm member 32 supported by the inner surface of the slide door 3.

  As shown in FIGS. 2 to 4, the slide rail 31 extends in the longitudinal direction of the vehicle body, and has an inner member 31a having a substantially L-shaped cross section and an outer member 31b having a substantially Z-shaped cross section. It is composed of And the groove part 31c is formed by joining the outer wall of the inner side member 31a, and the inner wall of the outer side member 31b, and the slide rail 31 is arrange | positioned so that the opening of the groove part 31c may face the vehicle width direction outer side.

  Further, the slide rail 31 is curved so that the tip side thereof is along the storage portion 17, and the portion disposed in the storage portion 17 is disposed on the inner side in the vehicle width direction than the seal surface 15. And the part which protruded the vehicle body outward from the accommodating part 17 is extended so that it may be gradually arrange | positioned from the inner side of the sealing surface 15 toward the outer side as it goes to the vehicle body rear.

  That is, the bead 16 is disposed on the outer side in the vehicle width direction with respect to the slide rail 31, and the lower side of the sealing surface 15 facing the position immediately before the corner 21b where the lower side 21a of the weather strip 21 rises and is connected to the vertical side. It is formed in the part 15a.

  On the other hand, the base end of the arm member 32 is supported by the inner surface of the slide door 3, and a roller (not shown) is rotatably supported at the distal end. The roller is slidably fitted in the groove 31c of the slide rail 31.

  Therefore, with the above-described configuration, the roller at the tip of the arm member 32 slides in the groove 31 of the slide rail 31 and the slide door 3 slides in the vehicle body front-rear direction, thereby opening and closing the door opening 14. Is done. Further, in the sliding door closed state, the arm member 32 is housed in the housing portion 17, the slide door 3 is smoothly moved toward the door opening portion 14 side, and the weather strip 21 contacts the seal surface 15.

  At this time, the lower side 21 a of the weather strip 21 abuts on the lower side 15 a of the sealing surface 15 and abuts only on the upper end of the bead 16. Thereby, even if the lower side portion 21 a of the weather strip 21 contacts the bead 16, no gap is generated between the lower side portion 15 a of the sealing surface 15 and the lower side portion 21 a of the weather strip 21. As a result, intrusion of water, dust, and sound such as rain water and car wash water into the vehicle interior 11 is prevented.

  When water such as rain water or car wash water flows along the outer periphery of the slide door 3 in the closed state of the slide door, the water crosses from the upper side of the weather strip 21 to the vertical side, and the vertical side It flows downward along. Next, the water that flows along the vertical side portion of the weather strip 21 flows down to the outside of the vehicle as it is or flows into the lower side portion 21a.

  Here, the water flowing into the lower side 21a of the weather strip 21 collides with a portion protruding downward from the lower side 21a of the weather strip 21 of the bead 16 (a portion below the upper end contacting the lower side 21a). And is drained downward along the bead 16 and drained. At this time, since the slide rail 31 is not disposed below the bead 16, the water drained by the bead 16 is drained outside the vehicle without flowing down on the slide rail 31.

Therefore, according to the slide door structure of the present invention, the bead 16 is provided at the front end of the lower side portion 15a of the sealing surface 15 that contacts the lower side portion 21a of the weather strip 21, and the bead 16 is arranged in the vehicle width direction with respect to the slide rail 31. On the outside , the water such as rain water and car wash water that has flowed into the lower side portion 21a of the weather strip 21 is formed on the slide rail 31 by extending vertically and projecting outward in the vehicle width direction. Without dropping, the beads 16 can be drained downward and drained. As a result, rust and freezing of the slide rail 31 can be suppressed, and the slide operation of the slide door 3 can be performed smoothly.

  Further, since the lower side 21a of the weather strip 21 abuts only on the upper end of the bead 16, there is no gap between the lower side 15a of the sealing surface 15 and the lower side 21a of the weather strip 21, so that the weather strip The water flowing into the lower side portion 21a of the 21 can be drained efficiently without deteriorating the sealing performance by the portion of the bead 16 protruding downward from the lower side portion 21a of the weather strip 21.

Further, the bead 16 is formed on the lower side portion 15a of the sealing surface 15 opposite to the position just before the corner portion 21b where the lower side portion 21a of the weather strip 21 rises, so that the water flowing from the vertical side portion of the weather strip 21 flows. can be drained by the bead 16 together, it is possible to improve the drainage efficiency.

  That is, when a bead is provided at a position far from the corner portion of the weather strip, drainage depends on the weight of the water itself between the corner portion and the bead, and the drainage effect by the bead is diminished. However, the drainage effect can be improved by providing the bead 16 at a position near the corner portion 21b of the weather strip 21 as in this configuration. Further, since the contact position of the weather strip 21 with the bead 16 is at the lowest position of the lower side portion 21 a, there is no possibility that the water that has flowed over the bead 16 will travel along the weather strip 21 beyond that.

  In this embodiment, the bead 16 is provided at the front end of the lower side 15a of the seal surface 15. However, if the slide rail 31 is not disposed below the bead 16, it may be provided anywhere on the lower side 15a. Absent. Further, although the bead 16 is provided on the outer side in the vehicle width direction from the slide rail 31, the bead 16 may be provided on the inner side in the vehicle width direction from the slide rail 31. That is, the bead 16 and the slide rail 31 may be arranged so as not to overlap in the vertical direction in the vehicle width direction. Furthermore, even when a slide door is provided on the right side of the vehicle, the configuration of the present invention can be applied.

  The present invention can be applied to a vehicle sealing structure in which the amount of water flowing into the lower side portion of the door weather strip is reduced to prevent water from entering between the lower side portion and the sealing surface on the vehicle body side.
