Fixing mechanism for a container in a vehicle air conditioning device

A fixing mechanism of a container in a vehicle air conditioning device main body comprising an air passage for an airflow from an air inlet port to a purified air discharge port, and comprising at least:

• a blower for generating the airflow,
• a filter unit for purifying air during the passage of the airflow,
• an evaporator for cooling the airflow
• at least one container containing at least one of an antibacterial agent and a fragrance agent arranged in the air passage,
• an inlet/outlet port for accessing the filter unit and defined by a wall surface of the main body, and
• a lid removably coupled to the main body for covering the inlet/outlet port wherein one of a filter frame arranged on the filter unit and the lid includes a first concave part and a first convex part spaced from the first concave part for receiving the at least one container therebetween and wherein the container includes a second concave part identical in shape to the first concave part and disposed on an end of the at least one container and further includes a second convex part identical in shape to the first convex part and disposed on an end of the at least one container opposite from the second concave part with the second concave part mating with the first convex part and the second convex part mating with the first concave part to define fixing means for removably fixing the container within the air passage,
• wherein the first concave part and the second concave part include a projection forming a depression part internally therein, and
• wherein the first convex part and the second convex part include a projection that interlocks with the depression part of the first and second concave parts.
