PURPOSE:To improve the vibrating property of a moving vane assembly, by providing dovetail grooves in the front and rear projections of the tips of moving vanes, providing joiners with blades, and inserting the joiners into the dovetail grooves. CONSTITUTION:The tip of each of moving vanes 1 are provided with front and rear projections 2, 3. The adjacent projections 2, 3 of the moving vanes 1 are located in contact with each other. Dovetail grooves 7 are provided in the peripheral surfaces of the projections 2, 3. Joiners 8 are inserted into the dovetail grooves 7 to couple the moving vanes 1 to each other. blades 9 project from the peripheral surfaces of the joiners 8. The moving vanes 1 are thus coupled together along the total circumference of a moving vane assembly to improve its vibrating property.
