Abstract: A railcar bogie includes: a protection target member of the railcar bogie; and a protective film including an adhesive surface stuck to the protection target member. The protective film is configured such that an impact absorbing layer and a flame-retardant layer are laminated in this order from the protection target member side. The impact absorbing layer is thicker than the flame-retardant layer.

Abstract: A paint film-protecting sheet, which is unwound from a roll for use, and in which occurrence of adhesive transfer at edges thereof is effectively prevented, and a method of manufacturing same are provided. The paint film-protecting sheet is in the form of a roll obtained by winding in a lengthwise direction a pressure-sensitive adhesive sheet formed of a substrate in continuous sheet form and a pressure-sensitive adhesive layer disposed on the substrate. The substrate comprises a resin component made primarily of polyethylene resin or polypropylene resin. The paint film-protecting sheet, after being unwound from the roll, has a percent shrinkage, in the lengthwise direction, of not greater than 1.2% when heated at 80° C. for 1 hour.

Abstract: A paint film-protecting sheet that provides a high level of weather resistance and minimizes staining of the paint film, and a substrate for such a sheet are provided. The paint film-protecting sheet has a pressure-sensitive adhesive (PSA) layer formed on a sheet-like substrate. The substrate has a surface resin layer (layer A) forming a surface of the substrate on the PSA layer side and one, two or more resin layers (layers B) superimposed on a back side of the layer A. The layer B contains an organic weathering stabilizer HMS having a weight-average molecular weight Mw of at least 1.5×103 in a predetermined amount Pb. The layer A is either free of the organic weathering stabilizer HMS or contains the stabilizer in a predetermined amount Pa which satisfies the condition Pa/Pb?0.5.
