An unloading device includes a pair of support bodies which supports side surfaces of a vulcanized tire vulcanized by a tire vulcanizer from the lower portion in a vertical direction, and a movement portion which moves the support bodies. The movement portion includes a horizontal movement mechanism which moves the support bodies in a horizontal direction from a position at which the vulcanized tire can be extracted from the tire vulcanizer to a position at which the vulcanized tire can be held by a PCI device for cooling the vulcanized tire, and a transport mechanism which transports the vulcanized tire, which is received from the PCI device by the support bodies, to a carrying-out destination.

Unloading device

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 ().
