PROBLEM TO BE SOLVED: To provide a blast cleaning apparatus by which a drying apparatus occupying a large installation area can be dispensed with a quick cleaning treatment is made possible, at the same time a dust-separation means and a circulation supply system of a cleaning solution are dispensed with, and further a simplification of the apparatus and a cost-reduction can be attained. SOLUTION: A blast chamber 3 is provided to enclose the lower half part 2b of a breathable endless transport means 2. A jet nozzle 4 is provided in the blast chamber 3, a gas-supply pipe 5 and a blast-cleaning material supply pipe 6 are connected to the nozzle 4. A blast cleaning material B is supplied to the nozzle 4 by the pipe 6, and the endless transport means 2 is cleaned by a mixed jet C of air flow A and the cleaning material B.
