Abstract
A shutter device includes fins made of a plurality of plate-shaped members. Each of the fins is configured to switch between a state of blocking an air flow and a state of not blocking the air flow, a frame is configured to rotatably support the fins, and a link member is configured to transmit a driving force to each of the fins to operate the fins. Each of the fins is provided with a support protrusion rotatably supported by the frame, and a driving protrusion rotatably supported by the link member. A plurality of supporting grooves that accommodate the support protrusions therein are formed in the frame to recess along a predetermined direction. The link member prevents the support protrusion from being removed from the supporting groove.
