Title:
EXTRUDED SHAPE FOR RAILROAD CAR AND STRUCTURE FOR RAILROAD CAR
Document Type and Number:
Japanese Patent JP2009298333
Kind Code:
A
Abstract:

To form a grooved rail for hanging easily by post-working without projecting utilizing a space (dead space) between two front plates.

An extruded shape 11 forming a side body structure includes a plurality of perpendicular webs 11c extended in the direction perpendicular to first and second front plates 11a and 11b and connecting the front plates to each other. In the second front plate 11b, a hanging groove can be formed at a corresponding portion between adjacent perpendicular webs 11c by forming a long hole 11f for interpositioning a support bolt to furnish an interior trimming material in the longitudinal direction of the extruded member by the post-working. On an external surface of the second front plate 11b, minute projections 11e extending in the longitudinal direction of the extruded member are formed at the center in the width direction of the corresponding portion between the perpendicular webs 11c. Each of the perpendicular webs 11c is provided with a restraint projection 11d extended in parallel with the front plates 11a and 11b and restraining an interposition of a head T1 of the support bolt T at a position corresponding to a height of the head of the support bolt T from the side where the long hole 11f is provided.
