Abstract

A regulator for regulating airflow through an air outlet includes a plurality of louver blades integrated with axis portions supported at bearing holes and interconnected through an interlocking member; a supporting plate with the bearing holes attached to an air outlet; and an elastic portion provided on the supporting plate to be capable of deforming along an axis of the louver blades. Also, the regulator may include a damper; a manual operating member for tilting the louver blades and damper; and two gears engaging each other and disposed at an interconnecting portion between the manual operating member and the damper. One of the gears is formed in two portions separated along an axis and provided coaxially. The two portions have slightly shifted pitch, and are able to displace with each other in a circumferential direction with elasticity.
