Abstract
A scroll casing has a scroll portion, a discharge portion provided with a discharge port, and a tongue portion. An extended plate has, in a cross section obtained by cutting in a thickness direction, a change point, at which an enlargement ratio of an area of the cross section is enlarged so as to be larger on a downstream side than that on an upstream side due to a change of inclination. In the extended plate, an angle θ1, and an angle θ2 satisfy a relationship of either 0≤θ2<θ1 or 0<θ2≤θ1. A distance L1 and a distance L2 satisfy a relationship of L2<L1.
