Abstract
The present invention relates to an impingement cooling mechanism that ejects a cooling gas toward a cooling target () from a plurality of impingement holes () formed in a facing member () that is disposed facing the cooling target (). Blocking members () that block a crossflow (CF), which is a flow formed by the cooling gas after being ejected from the impingement holes (), are installed on at least the upstream side of the crossflow (CF) with respect to at least a portion of the impingement holes (). Turbulent flow promoting portions () are provided in the flow path (R) of the crossflow (CF) regulated by the blocking members ().
