Abstract: A railroad vehicle fire-resistant floor structure with improved fire resistance against underfloor fires includes a mounting part for installing underfloor equipment on the lower surface of an underframe, and a fire-resistant member. The fire-resistant member is a fire-resistant coating applied to the lower surface of the underframe. The fire-resistant coating is preferably a foamable fire-resistant coating. A cover that covers an exposed portion exposed from the fire-resistant coating (foamable fire-resistant coating) is attached to the mounting part. The underfloor equipment is installed at the mounting part with a closing plate sandwiched therebetween.

Abstract: According to a railcar, a fuse member that couples a first end beam to a second end beam along a car longitudinal direction is formed as a channel material with an approximately U-shaped cross-section, including a web disposed to extend along the car longitudinal direction and a pair of flanges disposed upright from both end portions of this web. Accordingly, when a load received in collision exceeds a predetermined value, the fuse member buckles to allow the first end beam to move toward the second end beam to ensure reducing variation of the load that allows the first end beam to move toward the second end beam. Consequently, when the intended load is input, the first end beam is allowed to move toward the second end beam.

Abstract: When a bicycle is removed, a hook is first removed from a hooking ring and a rubber string built from a rim side of a wheel is removed from the wheel. Next, the wheel is removed from the space between a first rack member and a second rack member, thereby the second rack member is automatically and forcibly folded toward a base member and the first rack member through the forcible power of a spring hinge. At that time, although the second rack member collides with the base member or the first rack member, collision shock at the time of collision is relieved by a cushion member. After the bicycle is removed, based on that a seat of a flip-up seat is moved downward, the retaining space for the bicycle can be restored to passenger's seat.

Abstract: According to a railcar, a low-floor underframe includes side beams to which side bodyshells are coupled, a high-floor underframe includes a center sill disposed to extend in a car longitudinal direction at a center in a car width direction and a body bolster coupled to this center sill and to be an installation portion of a bogie, and the body bolster is coupled to the side beam by a coupling member. Thus, the car end compression load input to the high-floor underframe can be directly transmitted from the center sill and the body bolster to the side beams via the coupling member. This can disperse the car end compression load on the side bodyshells to ensure the car strength against the car end compression load.

Abstract: Provided is a sound absorbing panel that can satisfy the heat resistance properties and melting/dripping resistance properties required inside of a railway vehicle. A pier sound absorbing panel includes five sheets of first through fifth glass cloths that are stacked on an aluminum base plate. The edge section of the fifth glass cloth is affixed to the rear surface of the base plate using an adhesive, and the first through fourth glass cloths are fastened using staples. In other words, the first glass cloth and the base plate are fixed using an adhesive, and this adhesive is prevented from melting by the five sheets of the first through fifth glass cloths. The adhesive that fixes the edge section of the fifth glass cloth at the other surface of the base plate is prevented from melting by the five sheets of the first through fifth glass cloths and the base plate.

Abstract: Provided are a railroad vehicle that makes it possible to maintain the air tightness of a door and a plug door for a railroad vehicle. A second rail is provided parallel to a first rail in the longitudinal direction of a vehicle body above the leading edge side (door side) of a plug rail. The second rail supports the leading edge side of the plug rail. As a result, both edges of the plug rail are supported by the first rail and the second rail. Dangling of the leading edge side of the plug rail is thus prevented even when the plug distance (the distance that the door moves in the vehicle body width direction) is long. In this way, it is possible to block the doorway without leaving a gap using the door and to maintain the air tightness of the door.

Abstract: Provided is rolling stock in which a center beam is formed of an upper plate part, a lower plate part, and a pair of side plate parts located on opposite sides of the upper plate part and the lower plate part into a rectangular tube cross-sectional shape. Each of the upper plate part and the lower plate part is formed by placing a plurality of plate members on each other, at least an outermost one of the plate members is formed in a flat plate shape, and a ridge portion projecting to a tube inner side is formed in a center portion, in the width direction, of the plate member located on an inner side such that the ridge portion is continuous in a longitudinal direction of the center beam, and which has an underframe capable of preventing the upper plate part and the lower plate part from buckling.

Abstract: Provided is a rolling stock having a car body formed by joining side structures to an underframe, end structures, and a roof structure, the side structures having lower portions inclined toward an inside of the car body, the rolling stock having a structure allowing lower end portions of side posts of the side structures and side beams of the underframe to be securely joined. Side beams 21 in an underframe 20 of a rolling stock and lower end portions of side posts 31 having lower portions inclined toward an inside of a car body are joined by means of joint members 71. Each joint member 71 has a side-beam fixation plate portion fixed to an outer face of the side beam and a side-post fixation plate portion fixed to a side face of a lower end portion of the side post.
