PURPOSE: To provide a body of rolling stock retaining a shock-absorbing structure part inside it within a range outstandingly not-exceeding a size of the structural member without adding particular members to the inside of the body or a lower part of the floor in the body constituted of a hollow extrusion material. CONSTITUTION: In the body of the rolling stock composed of a hollow material 40, a hollow material 51 having a shock-absorbing function is provided on the hollow material 40 at an end part of a base frame 30 having a high possibility receiving a collision load. The hollow material 40 makes the longitudinal direction thereof as the longitudinal direction of the body. When the collision load is applied thereto, a part of the hollow material 51 is deformed and ruptured to absorb an impact force. An impact force to passengers is relaxed as small as possible at the time of collision of a train only by machining a part of the hollow material without totally varying the present body structure and a safety can be enhanced.
