Zusammenfassung:	PURPOSE: To raise film cooling capacity by having a suitable porous film cooling hole pattern consisting of a plurality of small film cooling holes which leans downward from high temperature side to low temperature side and are isolated densely from one another. CONSTITUTION: A suitable cooling hole pattern consists of many small film cooling holes 80, and these cooling holes 80 inclines acutely in the downstream direction from the high temperature side 61 of liners 48 and 50 to the low temperature side 57, and are isolated densely from one another. That is, for example, these cooling holes 80 have diameters of about twenty mill and tilt angles of about 20 deg., and are densely isolated from one another at intervals 6.5 to 7.5 times the diameter of the hole 80, and the holes 80 in the rows adjoining each other in axial direction are slid from each other in circumferential direction by about half the angle between the holes 80 adjoining each other in circumferential direction, which raises the equality of a cooling film more. Hereby, this liner can raise the film cooling effect.
