PURPOSE:To improve the effect of vibration damping and protect an engaging part from being broken off by making a connecting piece for connecting two moving blades adjacent to each other to be provided with connecting projections, which are to be inserted into connecting holes placed on the moving-blade surfaces opposing to the projections, on its both sides. CONSTITUTION:In the neighborhood of the rear edges 1a, 2a and front edges 1b, 2b on the tips of turbine moving blades 1, 2 adjacent to each other are provided shelves 10a, 10b and 11a, 11b projecting from the blade surfaces of moving blades in the opposite direction in such a manner as to be incorporated in a body. On the central part of each of these shelves 10a, 10b, 11a, 11b are provided connecting hole 12a, 12b, 13a, 13b which point in the direction intersecting perpendicularly with the blade surface of moving blades respectively. In addition, a connecting piece 16 for connecting the tips of the moving blades 1, 2 adjacent to each other is provided on the sides 16a, 16b which may come in close contact with the tips of the shelves 10a, 10b facing each other in such a manner that it is incorporated in one with connecting projections 17, 18 projecting in the opposite direction with each other. And further, the connection of the moving blades 1, 2 is completed by way of placing the connecting projections 17, 18 in the connecting holes 12a, 13b on the shelves 10a, 11b.
