PROBLEM TO BE SOLVED: To provide a pressure container being capable of suppressing scattering of fragments of a container main body of the pressure container to an outside even when the container main body is subjected to brittle fracture by an increase of an internal pressure while manufacturing the container main body by casting.SOLUTION: A pressure container 10 for electrical machinery comprises: a container main body 11 being manufactured by casting and formed with a housing space 9 capable of housing a part of an electric circuit constituting a power system inside thereof; and a coating portion 20 provided so as to surround an outside of the container main body 11. The coating portion 20 includes: a synthetic resin layer 22 being provided on an external surface 12 of the container main body 11 and constituted of synthetic resin; and a net-like synthetic fiber net 23 being provided so as to surround an outside of the synthetic resin layer 22 and constituted of synthetic fiber.SELECTED DRAWING: Figure 2 【課題】圧力容器の容器本体を鋳造により製作しつつ、内部圧力の上昇により容器本体が脆性破壊するような場合であっても容器本体の破片が外部に飛散することを抑制可能な圧力容器を提供する。【解決手段】実施形態によれば、電気機器用の圧力容器１０は、鋳造により製作されて、電力系統を構成する電気回路の一部を収容可能な収容空間９が内側に形成された容器本体１１と、当該容器本体１１の外側を囲うように設けられた被覆部２０とを有している。当該被覆部２０は、容器本体１１の外面１２上に設けられて合成樹脂で構成された合成樹脂層２２と、当該合成樹脂層２２の外側を囲うように設けられ且つ合成繊維で構成されており且つ網状をなしている合成繊維網２３とを有する。【選択図】図２
