To provide a truck frame for a railway vehicle which enables easy determination of reduction of joining strength of a side member and a center member constituting the truck frame.SOLUTION: The truck frame for a railway vehicle comprises: fastening bolts for joining a plurality of structure members constituting the truck frame; and a plurality of reinforcement members for joining the structure members. Each reinforcement member includes a first fiber reinforced plastic layer having first and second ends spaced apart from each other, and first and second ends being provided in the first fiber reinforced plastic layer and fitted to one of the structure members of the truck frame. A second fiber reinforced plastic layer is also disposed on the intermediate part of the first fiber reinforced plastic layer without covering the first and second ends on the first fiber reinforced plastic layer in order to increase the strength of the reinforcing member. The first and second ends are transparent or translucent.SELECTED DRAWING: Figure 13

    【課題】鉄道車両の台車枠を構成するサイド部材とセンター部材の接合強度の劣化を容易に判定できる台車枠を提供する。【解決手段】鉄道車両用の台車枠であって、台車枠を構成する複数の構造部材を接合する締結ボルトと、構造部材を接合する複数の補強部材とを有する。補強部材は、間隔をおいて配置された第1および第2の端部部分を有する第1の繊維強化プラスチック層と、第1の繊維強化プラスチック層に設けられ、台車枠の構造部材の一つに取り付けられる第1の端部部分と第2の端部部分とを有する。そして、補強部材の強度を強くするため、第1の繊維強化プラスチック層上で、第1の端部部分と第2の端部部分を覆うことなく、第1の繊維強化プラスチック層の中間部分に配置される、第2の繊維強化プラスチック層と、を有する。第1の端部部分と第2の端部部分は、透明または半透明である。【選択図】 図13
