Description

  The present invention relates to a seal structure applied to a vehicle including a sliding door.

  Some automobiles have a sliding door on the side of the vehicle body. An upper rail, a lower rail, and a center rail that extend in the front-rear direction are provided above, below, and behind the door opening that opens and closes the sliding door. The sliding door is provided with rollers that are supported so as to be able to roll on the upper rail, the lower rail, and the center rail, respectively, and the sliding door slides along the upper rail, the lower rail, and the center rail by the rolling of these rollers. .

  An opening is formed in the rocker (side sill) below the door opening, and the lower rail is provided on the back side of the opening. The rocker is provided with a linear seal member extending along the lower edge of the opening. Water, dust, or the like rolled up by the front wheels is likely to enter the opening. If water or dust gets into the opening, grease applied to the roller may be dropped with water, or sand may be caught between the roller and the lower rail, which may hinder smooth opening and closing of the sliding door. is there. In a state where the sliding door is closed, the filament seal member fills the gap between the sliding door and the rocker, thereby preventing water and dust from entering the opening.

JP 2009-143451 A

  In order to satisfactorily prevent water and dust from entering the lower rail, the linear seal member only needs to extend forward from the front end of the lower rail. However, when the linear seal member extends long forward, when the sliding door is a rear door, when the front door disposed on the front side of the sliding door is closed, the front door is moved to the front end of the linear seal member. Abut. Therefore, when the front door is closed, the front door receives a repulsive force from the linear seal member, and depending on the user, the front door may not be closed smoothly.

  Moreover, the filament sealing member is affixed on the rocker with the double-sided tape. Therefore, when the occupant gets on and off from the door opening, if the occupant's feet are caught by the linear seal member, the linear seal member may be peeled off from the rocker.

  Furthermore, there is also a problem that during the operation of attaching the filament seal member to the rocker, it is difficult to position the filament seal member, and variation occurs in the application position of the filament seal member.

  An object of the present invention is to provide a seal structure that can prevent entry of water, dust, or the like into an opening, and can suppress the occurrence of peeling of a linear seal member and variation in mounting position.

  In order to achieve the above-described object, the seal structure according to the present invention includes a sliding door that has an opening formed in a rocker below the door opening and is slidably supported by a lower rail provided on the back side of the opening. The rocker is provided with a linear seal member for filling a gap between the rocker and the sliding door along a lower end edge of the opening. The seal member includes a longitudinally extending portion extending in the vertical direction in front of the opening at the front end portion, and a longitudinal wall portion extending outward in the vehicle width direction is formed on a front end edge of the longitudinally extending portion, The longitudinally extending portion is provided with engagement means for engaging with the rocker for fixing to the rocker.

  According to this configuration, the longitudinally extending portion extending in the vertical direction is provided in front of the opening at the front end portion of the linear seal member. The longitudinally extending portion is formed with a longitudinal wall portion that extends outward from the front end edge in the vehicle width direction. Therefore, entry of water, dust, or the like from the front end portion of the opening can be satisfactorily prevented without extending the line seal member forward beyond the front end of the opening. As a result, entry of water or dust into the opening can be suppressed.

  Further, since the vertically extending portion is fixed to the rocker by the engaging means, even when the occupant gets on and off from the door opening, even if the occupant's foot is caught on the linear seal member, the linear seal member due to the catch Can be prevented. Furthermore, since the filament seal member can be attached to the rocker on the basis of the portion where the engaging means is engaged with the rocker, the occurrence of variations in the attachment position of the filament seal member in the rocker can be suppressed.

  Further, in the configuration in which the engaging means is provided in a portion other than the longitudinally extending portion of the linear seal member, water or the like may enter the inside of the rocker from a gap generated in the engaging portion between the rocker and the engaging means. . Since the engaging means is provided in the vertically extending portion, the engaging means is disposed at a relatively high position, so that water or the like can enter the gap generated at the engaging portion between the rocker and the engaging means. Can be suppressed.

  ADVANTAGE OF THE INVENTION According to this invention, the approach of water, dust, etc. to an opening part can be suppressed, and the smooth opening and closing of a sliding door can be ensured.
