Abstract
A nozzle according to one embodiment includes a nozzle unit and a guide surface. A first passage, a second passage, and the guide surface are provided to the nozzle unit. The first passage has a first open end. The second passage has a second open end, and a section that is positioned upstream of the second open end and that extends in a second direction. The guide surface has an edge in a first direction. The guide surface is exposed on the outer side at the edge, is along a third direction at the edge, the third direction being a direction becoming more distanced from an axis than the second direction does, as the third direction is extended further toward the first direction. A flow of fluid ejected from the second open end follows the guide surface, and becomes separated from the nozzle unit at the edge.
