Abstract
An air outlet device for an air conditioner includes a housing that also serves as an air outlet, swingable fins supported by the housing, a pinion gear portion that can swing with the fins, a rack gear portion that meshes with the pinion gear portion, and an operation portion that can linearly move with the rack gear portion. When the fins are swinging to a maximum swingable angle, a rack tooth portion of the rack gear portion, which meshes with the pinion gear portion, is a rack large tooth portion that is formed larger than the adjacent rack tooth portions.
