Abstract: A perfume dispenser for motor vehicles includes a support bearing a perfume-dispensing body, wherein the support has a generally circular base provided with slits and an articulated dorsal attachment coupled to a supporting structure of a motor vehicle, and a front arm connected to the base and bent in front of this to form an open receptacle. The perfume-dispensing body consists of a flattened cylindrical casing set in a projecting way within the receptacle and connected in a coaxially rotatable way to the base. The casing contains a hydrophilic material soaked with a perfumed fluid and has dorsal slits facing the slits of the base of the support.
