Abstract
A rotary machine includes damper pins and platforms each having a flat surface extending in an axial line direction. For each adjacent pair of the platforms, a damper abutting surface of a first of the adjacent pair of the platforms extends toward a damper abutting surface of a second of the adjacent pair of the platforms as approaching an outer side of a rotor blade stage in a radial direction while opposing each other in a peripheral direction. A damper accommodation space, which is defined by surfaces including the damper abutting surfaces, is defined between each adjacent pair of the platforms. Each of the damper pins defines a regular polygonal prism extending in the axial line direction and includes a damper pin main body in which an angle defined by two side surfaces corresponds to an angle defined by the damper abutting surfaces between the adjacent pair of the platforms.
