継手。A connecting shaft connected to the joint end at the root of the blade and extending in the longitudinal direction of the blade; an outer cylinder connected to the joint end on the rotating shaft side and extending in the same direction as the connecting shaft; An inner cylinder is pivotally connected to the outer cylinder through a pair of pins perpendicular to the cylinder axis direction of the outer cylinder, and the connecting shaft is connected to the side joint end so as to be relatively tiltable. is connected to the inner cylinder by a connecting pin having a phase difference of 90 degrees from the pair of pins, and the tip edge of the outer cylinder is connected to the joint end at the root of the blade with a good rose, so that when it is stationary, it can be connected at the same time. A blade joint for a rotating machine, characterized in that the bellows has bending rigidity capable of supporting the bending moment due to the weight of the blade.
