Abstract
A telescopic fan cage includes a main frame and a side frame which are slidably connected with each other to form a fan installation space. The side frame is capable of sliding toward the main frame to shrink the fan installation space, or sliding away relative to the main frame to expand the fan installation space. An apparatus case includes a casing and the telescopic fan cage. The telescopic fan cage is detachably disposed in the casing. Therein, the side frame is capable of sliding toward the main frame to shrink the fan installation space, so that the telescopic fan cage is at a transit state for moving in or out the casing; the side frame is capable of sliding away relative to the main frame to expand the fan installation space, so that the telescopic fan cage is at an installation state for being fixed in the casing.
