- a plurality of fins which are disposed in a direction crossing a flow of air passing through the ventilation passage, and which is capable of opening and closing the ventilation passage by way of turning operation,
- wherein the plurality of fins includes a first fin and a second fin that are adjacent to each other,
- a respective one of the first fin and the second fin has:
- a turning shaft portion which is turnably pivoted to the casing body;
- and
- a plate-shaped fin main body configured to control the flow of air passing through the ventilation passage,
- wherein a protrusion portion which protrudes in a thickness direction is protrusively provided at the fin main body of the first fin,
- wherein a contact portion configured to close a gap between the first fin and the second fin that are adjacent to each other by the contact portion coming into contact with the protrusion portion is provided in proximity to the turning shaft portion of the fin main body of the second fin,
- wherein each of the first fin and the second fin is provided with an inner portion which includes the turning shaft portion, and an outer portion which includes the protrusion portion, and
- wherein a predetermined portion of the inner portion, other than the turning shaft portion, is included in the outer portion.
