Abstract
A bag equipped with a bottom case, which is comprised of a bottom plate and a side peripheral wall and is integrally provided at its inner or outer surface with handle holding members and at its outer surface with caster mounting members, and which is coupled to an upper case made of fabric material or synthetic resin, is disclosed. The bottom case is detachably coupled to an upper case to allow only one case of both cases to be separated from the other case and to be cleaned or replaced with a new one. The bottom case is provided at its side wall with a reinforcing frame to prevent the side wall from being squeezed or broken. The bottom case is provided with handle mounting members to be integrally formed thereto or to be separated therefrom so as to diversify design and appearance of the bag.
