Abstract
A steam turbine is provided with moving blades which are affected less by erosion and fretting wear due to water and have a high reliability in strength. The moving blades are twisted moving blades, each provided with a blade portion and a shroud portion formed at its tip and a contact surface between shroud portions connecting adjacent moving blades whereby an extension plane of the contact surface toward the blade back side does not intersect with the blade tip of the blade back side shroud portion.
