摘要： Vane members have a space formed therein and a plate spring member is disposed inside the space of the vane members and elastically contacts inner surfaces of the vane members. The plate spring member includes a positioning portion, an elastic contact portion, and a connection portion. The elastic contact portion is divided into a plurality of segments in a length direction of the vane members. The elastic contact portion elastically contacts the inner surfaces of the vane members without any partial contact throughout an entire surface thereof. The elastic contact area between the elastic contact portion and the inner surfaces of the vane members is widened.

摘要： The invention includes vane members that have a space formed therein and a plate spring member that is disposed inside the space of the vane members and elastically contacts inner surfaces of the vane members. The plate spring member includes a positioning portion, an elastic contact portion, and a connection portion. The elastic contact portion is divided into plural numbers in the length direction of the vane members. As a result, in the invention, the elastic contact portion elastically contacts the inner surfaces of the vane members without any partial contact throughout the entire surface thereof. Accordingly, the elastic contact area between the elastic contact portion and the inner surfaces of the vane members is widened, so that self-excited vibration generated in a turbine vane may be reliably suppressed.
摘要翻译：本发明包括在其中形成有空间的叶片构件和设置在叶片构件的空间内并弹性地接触叶片构件的内表面的板簧构件。板簧构件包括定位部，弹性接触部和连接部。弹性接触部分在叶片构件的长度方向上分成多个。结果，在本发明中，弹性接触部分在叶片构件的内表面弹性地接触，而在其整个表面上没有任何部分接触。因此，弹性接触部与叶片构件的内表面之间的弹性接触面积变宽，能够可靠地抑制在涡轮叶片中产生的自激振动。

摘要： It is possible to easily and rapidly slot a blade root of a final (last) turbine rotor blade into a blade groove on a turbine disc even when the plan-view shape of a shroud of the turbine rotor blade is complex. A turbine rotor blade that is provided with a blade root that is slotted into a blade groove formed on a circumferential portion of the turbine disc to hold the whole blade, a blade portion that is exposed to high-temperature gas, a platform that supports this blade portion, a shank that connects the blade root and the platform, and a shroud that extends along the circumferential direction from the end of the blade portion has a cut-out portion cut out to a predetermined depth, either at the leading-edge or the trailing-edge of the blade root, along the lengthwise direction thereof from the end of the blade root to an intermediate part of the shank.
