Abstract
The present invention relates to an impingement cooling mechanism () that ejects a cooling gas (G) toward a cooling target () from a plurality of impingement holes () formed in an opposing member () that is arranged opposite the cooling target (). Turbulent flow promoting portions () are provided in the flow path of a crossflow (CF), which is a flow that is formed by the cooling gas (G) after being ejected from the impingement holes (). The turbulent flow promoting portions () are constituted so that a turbulent flow is promoted from the upstream side to the downstream side of the crossflow (CF).
