A luggage is formed of a main body, a cover body, and an expansion portion connecting the main body and the cover body. The main body has a frame which is provided in opposite inner sides with an expansion structure including two slide rails, an expansion board, and two retaining rods. The expansion board is fastened to a frame of the cover body such that the expansion board can be moved along the two slide rails. The holding capacity of the luggage can be thus adjusted.
