Abstract: A liquefied gas tank installed in a surrounding structural body includes: a tank main body in which a liquefied gas is storable, the tank main body including a plurality of planar portions and corner portions between the planar portions, the corner portions having less rigidity than that of the planar portions; a bottom supporting body that supports the tank main body from below the tank main body; and a plurality of side supporting bodies that support the tank main body from side of the tank main body. The tank main body is configured to stand by itself by being supported by the bottom supporting body when the tank main body stores no cargo, and be supported by the bottom supporting body and the side supporting bodies when the liquefied gas is stored in the tank main body.

Abstract: A crash energy absorber is provided at a front portion of a carbody of a railcar and configured to crush by a load from a front side to absorb crash energy. The crash energy absorber includes: a main absorbing portion extending in a front-rear direction; and a pair of sub absorbing portions respectively provided at upper and lower sides of the main absorbing portion. Each of the pair of sub absorbing portions is formed integrally with the main absorbing portion via breakable portions each extending in the front-rear direction.

Abstract: A bodyshell structure of a railcar, includes a plurality of side window opening portions formed on a side bodyshell along a railcar longitudinal direction, and the side window opening portions include a plurality of large window opening portions arranged on a railcar-longitudinal-direction center portion of the side bodyshell and a plurality of small window opening portions arranged on both railcar-longitudinal-direction sides of the large window opening portions and each having a smaller opening area than the large window opening portion.

Abstract: An obstacle deflector provided at a front portion of an underframe of a carbody of a railcar includes an obstacle deflecting plate configured to protect the carbody from an obstacle on a railway track when the railcar is traveling. The obstacle deflecting plate includes a main plate portion provided to receive the obstacle by a surface thereof and having a curved shape that is convex toward a front side in a traveling direction in plan view and a sub plate portion projecting toward a rear side from the main plate portion and is continuously provided along the main plate portion so as to extend from a convex, curved front end portion of the main plate portion toward a pair of left and right side portions of the main plate portion, the left and right side portions being located at the rear side in the traveling direction.

Abstract: A car includes a car equipment protection structure, The car equipment protection structure includes an underframe, couplers and guide members. Each of the guide members is provided on a railcar inner side of an attached flange portion of the underframe to which the couplers are attached. Moreover, the guide members respectively include inclined surfaces, each of which is opposed to at least a part of the coupler. Each of the inclined surfaces is inclined toward the railcar inner side as it extends downward.

Abstract: The present invention is a bodyshell structure of a railcar, the bodyshell structure including: a side bodyshell including an outside plate portion, an inside plate portion, and a joint portion configured to join the outside plate portion and the inside plate portion; an inside window opening formed on the inside plate portion and provided inside the railcar; and an outside window opening formed on the outside plate portion and having a smaller opening area than the inside window opening, and at least one of the inside window opening and the outside window opening has an oval shape extending in the railcar longitudinal direction or a circular shape.
