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.

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.

Railroad vehicle and plug door for railroad vehicle

A railroad vehicle that moves a door to an airtight position and maintains air tightness of the door without increasing the size of a cylinder device; and a plug door for a railroad vehicle. When a door moves to a position, a piston extends in the vehicle width direction, a pressing member is contacts the inner surface of the door, and the door is moved toward a door frame. An auxiliary pressing device brings the piston into perpendicular contact with the inner surface of the door making it is possible to efficiently move and press the door without increasing the size of a cylinder device even when the door must be moved across a distance to arrive at an airtight position. The main pressing device is used to press the door toward the door frame.

The present invention provides a vehicle seat which includes a seat back including a seat back body and an upholstery that covers front, back, and upper surfaces and both side surfaces of the seat back body. In the vehicle seat, the seat back body includes a frame having a frame shape and serving as a framework, a front-side cover portion placed so as to cover a front side of an inner space of the frame and supporting a back of a seated occupant, and a back-side cover portion placed so as to cover a rear side of the inner space. The front-side cover portion and the back-side cover portion are covered by the upholstery. The back-side cover portion includes a flexible back-side sheet body stretched across the frame.

Vehicle seat

The present invention provides a vehicle seat which includes a seat frame, a seat cushion receiving member stretched across the seat frame, and a seat cushion placed on the seat cushion receiving member. In the vehicle seat, the seat cushion has such dimensions as to cover the seat frame as viewed in plan, and a lower surface of the seat cushion has a raised portion in a region covering the seat frame, and the raised portion is raised so as not to contact the seat frame.
