摘要

Provided is a stationary vane unit (9) of a rotary machine in which a plurality of stationary vane members (10) is arranged around a central axis and outer shrouds (12) provided in the outer peripheries of the respective stationary vane members (10) are continuous and connected in the circumferential direction, the stationary vane unit including: a first band member (20) that extends in the circumferential direction and comes into contact with the outer shrouds (12) of the plurality of stationary vane members (10) from one side thereof in a main axial direction in which the central axis extends; a second band member (30) that extends in the circumferential direction and comes into contact with the outer shrouds (12) of the plurality of stationary vane members (10) from the other side thereof in the main axial direction; and a fastening member (40) that fastens the first band member (20) and the second band member (30) to each other so that the outer shrouds (12) of the plurality of stationary vane members (10) are connected to each other.
