<p>A turbine having moving vane such that even if the length is made short or even if such vanes are used for a turbine of low rotational speed, the vanes can be joined tightly with no gap so that a high vibration attenuation effect may be produced. The turbine moving vane is characterized in that a joint member facing adjacent vanes has its circumferential peripheral face formed into a slope inclined in the axial direction with respect to the circumferential direction of the turbine, that at least one slope facing the adjacent vanes is provided with a groove extending in the slope direction, and that an auxiliary joint pin is inserted into the groove while a torsional moment is being applied to the vane portion of the moving vane embedded in a disc thereby to restrict the torsional return of the vane portion.</p> |
