Abstract
An airflow-direction adjustment device includes a housing in which a front end side is set as an air outlet and a back end side is set as an air inlet; a fin turnably supported inside the housing; and a gear mechanism for adjusting a direction of the fin by a rotation of an operating portion. An essential part is formed such that the fin is formed by a pair of vanes disposed on right and left or top and bottom inside the housing, and each vane is turnably supported in a front-and-back direction of the housing respectively as a supporting point on a common pivot line set in a plate width direction.
