Strap bar receiving parts hanging downward from the roof bodyshell part are fixed to the roof bodyshell part. An upper horizontal member and a lower horizontal member are provided like bridges between the paired side bodyshell parts. The upper horizontal member and the lower horizontal member are disposed at an interval in a vertical direction and connected by connection pipes. The upper horizontal member is formed by a plurality of reinforcement pipes and the lower horizontal member is formed by a plurality of reinforcement pipes. At least one ends of the plurality of reinforcement pipes are fixed to the strap bar receiving parts. ## Claims ### Claim 1 A railcar including a under frame, paired side bodyshell parts respectively provided on opposite sides of the under frame in a car width direction, a roof bodyshell part provided like a bridge between upper end portions of the paired side bodyshell parts, and an end bodyshell part, the railcar having a reinforcement structure, wherein the reinforcement structure includes hanging members having one ends fixed to the roof bodyshell part to extend downward from the roof bodyshell part, an upper horizontal member provided in an upper portion of a car interior and disposed like a bridge between the paired side bodyshell parts; a lower horizontal member provided in the upper portion of the car interior and disposed in a position displaced downward from the upper horizontal member like a bridge between the paired side bodyshell parts, and a connection member for connecting the upper horizontal member and the lower horizontal member, wherein the upper horizontal member has a plurality of upper reinforcement members at least one ends of which are respectively connected to the hanging members and the lower horizontal member has a plurality of lower reinforcement members at least one ends of which are respectively connected to the hanging members. ### Claim 2 (depends on 1) The railcar including the reinforcement structure according to claim 1, wherein the plurality of connecting members are provided between the upper horizontal member and the lower horizontal member. ### Claim 3 (depends on 2) The railcar including the reinforcement structure according to claim 2, wherein the plurality of connecting members form a truss structure together with the upper horizontal member and a lower horizontal member. ### Claim 4 (depends on 2) The railcar including the reinforcement structure according to claim 2 further including luggage shelves respectively provided to the paired side bodyshell parts and extending in a longitudinal direction of the car, wherein the reinforcement structure includes a first reinforcement structure part and a second reinforcement structure part, the first reinforcement structure part includes a first upper reinforcement member and a first lower reinforcement member having one ends fixed to the hanging member and the other ends fixed to the luggage shelf and a first connection member for connecting the first upper reinforcement member and the first lower reinforcement member, the second reinforcement structure part includes a second upper reinforcement member and a second lower reinforcement member having opposite ends respectively connected to the hanging members and a second connection member for connecting the second upper reinforcement member and the second lower reinforcement member, and the respective luggage shelves form a truss structure together with the first reinforcement structure part and the second reinforcement structure part. ### Claim 5 (depends on 4) The railcar including the reinforcement structure according to claim 4, wherein the reinforcement structure further includes seat members positioned below the respective luggage shelves and respectively provided to the paired side bodyshell parts, a rod-shaped member for connecting the luggage shelf and the seat member, and a third reinforcement structure part standing on the under frame to support and reinforce the seat member. ### Claim 6 (depends on 5) The railcar including the reinforcement structure according to claim 5, wherein the third reinforcement structure part has an inverted triangular sectional shape and has a lower end portion connected to the under frame and an upper side portion supporting a seat portion of the seat member. ### Claim 7 (depends on 5) The railcar including the reinforcement structure according to claim 5, wherein the third reinforcement structure has a member, provided to the under frame, extending in the longitudinal direction of the car, and having a hat-shaped section, and a first support member connecting the member and the seat member. ### Claim 8 (depends on 5) The railcar including the reinforcement structure according to claim 5, wherein the third reinforcement structure has a receiving member provided to a cross beam of the under frame and a second support member provided between the seat member and the receiving member. ### Claim 9 (depends on 1) The railcar including the reinforcement structure according to claim 1 further comprising a strap attachment having a strap bar which extends in the longitudinal direction of the car and from which a plurality of straps hang at intervals in the longitudinal direction of the car and strap bar receiving parts fixed to the roof bodyshell part to respectively support the strap bar, wherein the hanging members are the strap bar receiving parts of the strap attachment.
