    • A rolling stock includes: a pair of left and right post members provided upright on inner sides of left and right end portions of an end beam of an underframe, the end beam joined to a lower portion of a cab end structure; a recess portion open frontward, the recess portion formed in a front portion of the end beam between the pair of post members; and an impact absorbing member disposed between a bottom face of the recess portion and an inner face of the outside plate. The recess portion has such a size that the impact absorbing member is accommodated within the recess portion after being compressively deformed. Since the impact absorbing member is disposed on an inner side of the outside plate, the impact absorbing member is not exposed to the outside of the car body, and thus does not impair the design of the car body.

    • The present invention relates to a photosensitive resin composition excellent in pliability, ultraviolet sensitivity for development, developability with an aqueous alkali solution, and storage stability at room temperature and a circuit substrate employing the same. The photosensitive resin composition includes a siloxane-containing polyamic acid resin having structural units respectively represented by the following formulae (1), (2), and (3) and a photopolymerization initiator incorporated therein. The circuit substrate is coated with the photosensitive resin composition. In the formulae, Ar represents a residue of an aromatic tetracarboxylic acid; R1 represents alkyl group having 1 to 6 carbon atoms or phenyl group; R2 represents alkylene group having 2 to 6 carbon atoms or phenylene group; l represents a number of 0 to 10; R3 represents a divalent group or a direct bond; R4 represents —CH2═CH—R6—, in which R6 represents a direct bond, alkylene group having 1 to 6 carbon atoms, or phenylene group; R5 represents a diamine residue; and m, n, and o, indicating the range of the abundant molar ratios of the respective structural units, are 0.3 to 0.95, 0.05 to 0.7, and 0 to 0.5, respectively.
