PROBLEM TO BE SOLVED: To provide a turbine moving blade and a turbine that are high in structural reliability, by keeping the turbine moving blades to be brought into contact with each other and implementing vibration proof. SOLUTION: In the turbine, rotor side hooks 63, 64 are circumferentially disposed on an outer peripheral edge of a turbine rotor 6. The rotor side hooks 63, 64 are fitted in moving blade side hooks 31, 32 formed in a groove portion 3 of a blade to fit and fix the plural turbine moving blades 10, 10. Upper faces of the moving blade side hooks 31 are inclined with respect to lower faces of the rotor side hooks 63 circumferentially formed on the outer periphery of the turbine rotor 6. Each lower face of the rotor side hook 63 is brought into contact with each upper face of the moving blade side hook 31 at a point to form a wedge-shaped gap 66. During operation of the turbine, outward force, generated from centrifugal force, in a radial direction of the turbine rotor 6 acts on the turbine moving blade 10, so that the turbine moving blade 10 falls down toward a direction to narrower the wedge-shaped gap to be disappeared. At this time, an apparent length in a circumferential direction is extended, so that shroud covers 1, 1 on the top of neighboring two turbine moving blades 10, 10 are brought into contact with each other.
