Generally, buildings such as apartments, office buildings, and residential buildings maintain very high airtightness in order to minimize the consumption of heating and cooling energy, and most have central control type air conditioners in order to comfortably create an indoor environment.

The air conditioner is used to filter fresh air outside the building and supply it to the inside of the building, or to supply cold air or hot air to the room.

There are many different types of air conditioners and they include air supply ducts for supplying air to the room. The duct, for example, is placed on the ceiling of the room and supplies air to every corner of the room.

In addition, a diffuser for the air duct is installed at the end of the duct for supplying air more efficiently. The diffuser for the air duct installed in the duct for air supply is configured to perform the function of spreading the air passing through the duct to a wider range of the indoor space.

Accordingly, the present invention is an improvement of a conventional air duct duct diffuser. First, an example of a conventional air duct duct diffuser is disclosed in Korean Patent Publication No. 2005-0080304 entitled " The contents of which will be referred to as "equipment").
