A railcar includes a side sliding door and entrance peripheral-member surrounding the side entrance. The entrance peripheral-member includes a door pocket post in which outer and inner portions are inwardly of the outer portion in car-width direction coupled to each other. The side sliding door peripheral portion is pressed against an edge portion, extending along the side entrance of the entrance peripheral-member via a rubber seal at the side entrance closed state. In the side entrance open state, the side sliding door is pulled into a door pocket space facing the door pocket post inner portion. A portion projecting inwardly in car-width direction beyond the inner portion and including a tip end contacting the rubber seal provided at at least part of region constituted by portions of upper and lower edges of the side entrance peripheral-member and lateral edge at the edge portion door pocket post side of the entrance peripheral-member.

In energy absorbing structures in an entire train, a compression amount at an interface between cars at an end portion of a train is reduced and compression at an interface between cars at a center portion of the train is facilitated. In the structure, a plurality of cars (Ato A) are coupled to one another through couplers (Bto B), and energy absorbing structures (Sto S, Sto S) are provided between cars. An average compressive load corresponding to a value obtained by dividing an energy absorption amount of the energy absorbing structure by a maximum compression amount of the energy absorbing structures (Sto S, Sto S) is set smaller at an interface between cars at a center portion of the train than at an interface between cars on an outer side of the train (closer to an end portion).
