Abstract
An object is to provide an air conditioning unit and a vehicular air conditioning device that can efficiently distribute conditioned air while preventing an increase in the dimensions of a damper. The air conditioning unit includes a main duct (D1), a subduct (D4) branching from the main duct (D1) and guiding air to a foot outlet port (24), and a second switching damper (30) disposed in the subduct (D4) facing the main duct (D1). The second switching damper (30) includes a rotating shaft (31) and a damper body (32) including a guiding shroud (33) extending in the circumferential direction around the rotating shaft (31). An end flange (34A) at one circumferential end of the damper body (32) protrudes into the main duct (D1) as a result of rotation of the second switching damper (30) around the rotating shaft (31). A radial length (R1) of an end flange (34A) is greater than a radial length (R2) of an end flange (34B) at the other circumferential end of the guiding shroud (33).
