Abstract:
In the present invention the end plate (60) of a blade (50) has a gas path surface (61) facing a combustion gas flow passage (49) side, an end surface (63) along the edge of the gas path surface (61), multiple passages (81p), and a baseboard hole (75p). The multiple passages (81p) extend along the direction of an end surface portion (63p), which is a portion of the end surface (63), and are arranged in the direction toward and away from the end surface portion (63p). The baseboard hole (75p) opens at the end surface portion (63p). The baseboard hole (75p) communicates with an inside passage (83p), which is the passage among the multiple passages (81p) that is farthest from the end surface portion (63p).
