The present invention relates to a rail vehicle including a door column with finger protection rubber.

  In recent years, rail vehicles (railway vehicles) tend to be strongly demanded to reduce production costs and improve quality in addition to high performance and comfort. In order to reduce the manufacturing cost, it is necessary to manufacture a vehicle structure with high dimensional accuracy so that interior parts such as chairs, hanging leather, grip bars, and cargo racks can be attached with a small number of work steps.

  In order to produce a vehicle structure with high dimensional accuracy, a plurality of aluminum hollow extruded shapes (hereinafter referred to as extruded shapes) are arranged along the direction of extrusion, and the joint ends are distorted (deformed) with a small amount of heat input. The technique of joining by the friction stir welding which is hard to produce is being adopted. By assembling the roof structure, side structure, underframe and the like manufactured in this manner into a box shape, it becomes possible to manufacture a vehicle structure with higher dimensional accuracy than a conventional vehicle structure. A rail vehicle indicates a vehicle that travels along a guideway disposed on the ground side, and includes a vehicle that is used for a railway vehicle, a streetcar, a monorail, a new transportation system, and the like. Hereinafter, a rail vehicle will be described as an example of a rail vehicle.

  In order to reduce the number of man-hours for attaching interior parts, modularization has been promoted by reducing the number of parts by consolidating hanging leather, handrails, cargo racks, and the like. The interior module is a predetermined inside of the vehicle structure by a restraint that combines a special bolt and a nut with a curtain rail (or T-shaped slot, T-shaped groove) that is integrally formed with the extruded shape member constituting each structural body. Fixed in place.

  About a load shelf module and a ceiling module, it can attach simply to the predetermined location inside a vehicle structure. However, in the case of a door pocket module disposed in the vicinity of a movable part such as a sliding door used for entering and exiting passengers, etc., with respect to the finger protection rubber receipt that is one of the components constituting the door pocket module, the gap with the sliding door Since adjustment work is required, after attaching the door pocket module to the vehicle structure, the gap between the sliding door and the sliding door was fixed to the door pocket module while adjusting the gap by matching the actual thing. Since this fixing method is a method in the actual object matching work, not only the mounting man-hours are increased, but also there is a point that should be improved, for example, a chip cleaning work occurs due to the drilling work.

  In Patent Document 1, the side sliding door pocket portion of the railway vehicle entrance / exit portion is composed of a door pocket inner wall to which a decorative plate is attached and a door pocket pillar provided at an end thereof, and a grip bar is integrated with the door pocket column. A door structure for a railway vehicle that is modularized is disclosed. A rubber cover for finger protection is attached by elastic fitting on the side opposite to the side where the recessed groove into which the inner wall of the door pocket of the door pocket pillar is inserted is formed. The mounting position of the rubber cover is fixed and is not variable.
