PROBLEM TO BE SOLVED: To design a structure of a double skin shape having a curtain rail like projection groove, so as to solve various problems following a fact that a curtain rail like projection grove projects to the surface of a conventional double skin shape having a front plate and a back plate interconnected via a tilt rib. SOLUTION: In each double skin shape of a rolling stock, a front plate and a back plate are interconnected via a tilt rib. The rib for connecting the front plate to the back plate is a vertical rib vertical to the front plate and the back plate. Two vertical ribs are paired adjacently, the pair of vertical ribs are arranged with a predetermined interval. Proximities of the front plates of the pair of adjacent vertical ribs are connected to the front plates via a connecting part of parallel curtain rail like grooves, and slots are disposed in the front plates in with the pair of vertical ribs, thereby forming the curtain rail like grooves.
