This contact portion 6A is inserted into the groove of the sill 4 and, as shown in FIG. 7, is always in contact with the car (not shown) side of the vertical surface forming the groove of the sill 4. Thereby, the clearance gap produced between the sliding door 3 and the threshold 4 can be obstruct | occluded. Since the cross section of the contact portion 6A is a curved surface, the contact area with the vertical surface of the groove of the sill 4 is reduced. Therefore, when the door is opened and closed, the frictional resistance is reduced, and the door opening and closing operation is smooth.

Next, the structure of the door stopper lower part airtight component 7 is demonstrated based on FIG.
As shown in FIG. 8, the door bottom lower airtight component 7 is composed of a main body 7 </ b> C and a contact member 7 </ b> G. The main body 7C has a bottom portion 7F, and a first vertical portion 7D and a second vertical portion 7E that respectively extend in the vertical direction from the bottom portion 7F, thereby forming a recess. The first vertical portion 7D and the second vertical portion 7E are provided in parallel, and the first vertical portion 7D is longer in the horizontal direction than the second vertical portion 7E and shorter in the vertical direction. ing. On the other hand, the contact member 7G has an L shape extending downward from the first vertical portion 7D and forms a contact portion 7A having the same shape as the contact portion 6A of the lower airtight component 6.
The concave portion of the main body 7C of the door-holding lower part 7 can be fitted into a notch 3B formed at the lower end of the door-holding surface 3A of the sliding door 3, and when fitted, the inner surface of the first vertical portion 7D is the door surface 3A. The inner surface of the second vertical portion 7E contacts the inner side of the door contact surface 3A, and the inner surface of the bottom portion 7F contacts the edge of the notch portion 3B. Further, the outer surface of the bottom 7 </ b> F comes into contact with the fixing portion 6 </ b> B of the lower airtight component 6. Here, the second vertical portion 7E has a horizontal dimension shorter than the width of the door contact surface 3A. For this reason, when the door-holding airtight part 7 is fitted into the notch 3B formed at the lower end of the door-holding surface 3A, two U-faces facing each other and the second face are formed on the inside of the U-shaped portion of the sliding door 3. A space 11 is created between each side surface of the vertical portion 7E.
As shown in FIG. 6, the contact portion 7 </ b> A of the door-holding lower airtight component 7 is always in contact with the car (not shown) side of the vertical surface forming the groove of the sill 4. Since the frictional resistance is reduced, the door opening and closing operation is smooth. The door bottom lower airtight component 7 is made of an elastic material such as chloroprene rubber or ethylene propylene rubber. For this reason, the 1st and 2nd vertical parts 7D and 7E which form the recessed part of the door-holding lower part airtight component 7 have elastic force in the opening-and-closing direction of the sliding door 3, and the said recessed part is the lower end of 3 A of dooring surfaces of the sliding door 3 When inserted into the notch 3B formed in the shape, the first and second vertical portions 7D and 7E sandwich the lower end including the notch 3B of the door contact surface 3A of the sliding door 3 by elastic force, and thereby the door contact surface 3A. The lower end of can be fitted.
