Abstract
Provided is a pressure vessel having a weld portion structure of a plate material in which a plate receiving a pressure or a load is attached by welding to a wall surface member such as a shell or a head. In the pressure vessel, a stress concentration on the weld portion structure is alleviated and an increase in welding amount and plate thickness of the wall surface member are suppressed. The pressure vessel includes a weld structure portion in which an end of a bolster plate () attached so as to partition an inside of a container body and receiving a pressure or a load is attached by welding to a wall surface member () of the container body, the weld structure portion having at least two sections including a weld portion (), i.e., shape displacement points of the weld portion () and a stepped portion ().
