A ventilator includes a first louver, second louvers, side walls, a first inclined member, and a convex part. The first inclined member is inclined so that an opening area widens from the upstream side to a downstream side. The first inclined member has a vertex of inclination in a cross-sectional view that is positioned at the upstream side. The convex part is arranged adjacent at the upstream side in the airflow direction to the vertex. In a maximum angle state in which the first louver is rotated so that an upstream end part of the first louver is closest to the first inclined member, the upstream end part is positioned further to the downstream side in the airflow direction than the vertex. The convex part projects further to an inside of the flow path than the vertex, and extends across the second louvers when seen along the airflow direction.
