To provide a silencer which can prevent a crack of a flank plate, and can secure safety at the traveling of a railway vehicle, and a railway vehicle having such a silencer.SOLUTION: A silencer 4 connected to an exhaust system of a diesel engine comprises a hollow cylinder part 41 having a center axis along a direction in which an exhaust gas flows. In the silencer 4, an internal space of the hollow cylinder part 41 is partitioned to a plurality of silence chambers (for example, a first silence chamber 414, a second silence chamber 415 and a third silence chamber 416) by partitioning plates 413A, 413B which are arranged orthogonal to the center axis, and connected to an internal peripheral face of the hollow cylinder part 41. The diesel engine is for use in a railway vehicle, and a heat insulation material (for example, glass wool 46) is attached to a face at which the silence chambers (the first silence chamber 414, the second silence chamber 415 and the third silence chamber 416) of the partitioning plates 413A, 413B are formed.SELECTED DRAWING: Figure 3

    【課題】胴板の割れを防止し、鉄道車両の走行時の安全性を確保することが可能な消音器およびそのような消音器を備える鉄道車両を提供すること。【解決手段】ディーゼルエンジンの排気系に接続される消音器4であって、排気ガスの流れる方向に沿って中心軸を有する中空円筒部41を備え、中心軸に対し直角に配置されるとともに中空円筒部41の内周面に結合された仕切り板413A,413Bにより、中空円筒部41の内部空間が、複数の消音室(例えば、第1消音室414、第2消音室415、第3消音室416)に区切られた消音器4において、ディーゼルエンジンは、鉄道車両用であること、仕切り板413A,413Bの、消音室(第1消音室414、第2消音室415、第3消音室416)を形成する面に、断熱材(例えば、グラスウール46)が取り付けられている。【選択図】図3
