|1. (WO2018198664) SHUTTER DEVICE|
The shutter device (30) is provided with: multiple fins (31), each comprising a plate-like member, for switching between a cutoff state wherein airflow is cut off and an open state wherein air can pass through by rotating about a rotary shaft (310) disposed along the longitudinal direction of the fin; and seal members (313, 314), each comprising a member formed of a flexible material and formed so as to extend toward the outside from an end of the fin perpendicular to the rotary shaft. When one of a pair of adjoining fins is defined as a first fin and the other as a second fin, in the cutoff state, the seal member disposed on the first fin is pushed against the second fin by the force exerted by the air.
