PURPOSE: A diffuser for air-conditioning is provided to change angle of diffusion of air while applicable to the diffuser with a plurality of air diffusing members. CONSTITUTION: A diffuser includes at least three lifting units(20) installed at regular intervals, and having cylinder tubular bodies(21) perpendicularly fixed to an upper connecting member of a first diffusing member(11), and lifting rods(22) linearly lifted up from and to the cylinder tubular bodies. A second diffusing member(12) and a third diffusing member(13) are integrally fixed by a fixing tube member(14). The lifting rod of the lifting unit is fixed to an upper connecting member of the second diffusing member to allow the second diffusing member and the third diffusing member to be lifted up and down. The first diffusing member is mounted on an inside of a frame(10). The cylinder tubular body has a plurality of hook parts formed on a lower end thereof, and inserted and fixed to holes of the upper connecting member of the first diffusing member. A damper unit(40) is mounted on an upper part of the frame to control amount of supplied air.
