  However, as in Patent Document 1, in the structure in which the groove formed in the bottom portion of the sliding door is engaged with the lower rail provided in the scraper portion, the lower rail and the groove There is a gap between them. Therefore, noise generated during traveling enters the vehicle through this gap.

  In addition, when the door end side end of the door end rubber is formed in an arc shape, even if the lower end of the door end rubber and the lower end of the sliding door main body have the same height, a groove is formed in the bottom of the sliding door. If provided, the door end rubbers cannot be brought into contact with each other at the lower end of the door end rubber. Therefore, when the door end side end portion of the door end rubber has an arc shape, the height of the lower end of the door end rubber is set above the lower rail. As a result, the sound generated during traveling is likely to enter the vehicle.

  Accordingly, an object of the present invention is to provide a sliding door structure for a railway vehicle that can prevent noise generated during traveling from entering the vehicle.

Therefore, it is possible to suppress the sound generated during traveling from entering between the lower ends of the sliding doors 3a and 3b and the lower edge of the entrance 1a.
Moreover, since the sliding doors 3a and 3b are guided to the vehicle outer side by the upper guide mechanism 6 and the lower guide mechanism 12 immediately before reaching the closed position, the door main body 31 can be pressed against the contact surface 11b.
Moreover, since the part which contacts the contact surface 11b of the door main body 31 is comprised by the lower compression member 34 which can be elastically deformed, the door main body 31 can be pressed on a lower contact part, and can be made to adhere more reliably. . As a result, intrusion of traveling sound can be more reliably suppressed.

Moreover, in this embodiment, when the surface (front end surface of the protrusion part 32a) which faces the contact surface 11b of the door elastic member 32 is orthogonal to the vehicle width direction, when the sliding doors 3a and 3b are in the closed position, The protruding portion 32a of the tip elastic member 32 contacts the contact surface 11b. Therefore, it can suppress more that the sound which generate | occur | produces at the time of driving | running | working enters into a vehicle from between the lower end part of the sliding doors 3a and 3b and the lower edge of the entrance / exit 1a.
Moreover, since the door-end elastic member 32 is comprised with the elastic body, the door-end elastic member 32 can be pressed on a lower contact member, and can be made to adhere more reliably. As a result, intrusion of traveling sound can be more reliably suppressed.

In the present embodiment, when the sliding doors 3a and 3b are in the closed position, the upper end portion of the side surface of the door body 31 is provided with the upper compression member 7 (upper contact portion) provided along the upper edge of the entrance 1a. Therefore, it is possible to suppress sound generated during traveling from entering between the upper ends of the sliding doors 3a and 3b and the upper edge of the entrance 1a.
Further, since the sliding doors 3a and 3b are guided to the vehicle outer side by the upper guide mechanism 6 and the lower guide mechanism 12 immediately before reaching the closed position, the door main body 31 can be pressed against the upper compression member 7 (upper contact portion). it can.
Moreover, since the upper compression member 7 which contacts the door main body 31 can be elastically deformed, the door main body 31 can be pressed against the upper compression member 7 and can be made to adhere more reliably. As a result, intrusion of traveling sound can be more reliably suppressed.

  Further, in the present embodiment, when the sliding doors 3a and 3b are in the closed position, the upper end portion of the inner surface of the door tip elastic member 32 is in contact with the upper compression member 7, so that the sound generated during traveling is the sliding door 3a, Intrusion into the vehicle from between the upper end of 3b and the upper edge of the entrance 1a can be further suppressed.
