Abstract
A blade or vane row including a plurality of blade or vane segments (), each including a blade or vane body (), being disposed in a rotational direction to form an annular shape and defining a flow path (R) along which working fluid (G) flows. The blade or vane segments () each have an end wall portion () that faces the flow path (R) and extends in a rotational direction. The blade or vane body extends from the end wall portion, and the blade or vane body is disposed in the flow path (R). Surfaces (A,B) of the end wall portion () in the rotational direction each include an inclined portion (). The inclined portion is inclined so as to extend to a flow path (R) side and downstream in a turn direction of the working fluid (G) that flows along the flow path (R).
