To provide an aluminum frame, which can correspond to the surface of a glass door freely and to which a dustproof packing for the aluminum frame capable of being mounted and demounted to and from the aluminum frame simply by force in the extent of the pushing of a finger is secured.

In the aluminum frame, a glass-mounting air gap section 3 is formed at one end of a top face by installing forward projected eaves 1 and the dustproof-packing mounting groove 5 for securing the dustproof packing 7 with a dustproof-packing upper edge section 4 composed of elastomer, rubber, soft resin having proper elasticity or the like at the other end, and an aluminum frame material in which an aluminum-frame connecting section 2 is set up onto the front is framed and constituted.
