1. A ventilator configured to blow air through a flow path from an opening part, the ventilator comprising:
a first louver on which a knob is mounted;
a plurality of second louvers each extending in a direction intersecting a longitudinal direction of the first louver, and arranged further to an upstream side in an airflow direction than the first louver;
a pair of side walls rotatably supporting the first louver, and the side walls defining a portion of the opening part;
a first inclined member defining a portion of the opening part between the pair of side walls, and the first inclined member being inclined so that an opening area of the opening part widens from the upstream side to a downstream side in the airflow direction, the first inclined member having a vertex of inclination in a cross-sectional view that is positioned at the upstream side in the airflow direction; and
a convex part arranged adjacent at the upstream side in the airflow direction to the vertex, wherein
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 in a direction orthogonal to both a rotation axis of the first louver and the airflow direction, and the convex part extends across the plurality of second louvers when seen along the airflow direction, and
in the direction orthogonal to both the rotation axis of the first louver and the airflow direction, in the maximum angle state, the convex part projects further inside the flow path than a position of a proximal end part of the first louver closest to the first inclined member.
