To provide a cleaning machine for joint between walls of an underground continuous wall capable of smoothly cleaning the joint between walls by reducing resistance to a brush part without degrading cleaning capacity.
A brush part 21 rubbing and removing attached substance stuck to a joint between walls is fitted to a cleaning machine main body 20 so as to be slanted against the projecting direction of the joint between walls. When the cleaning machine main body 10 is vertically moved, because the brush part 21 rubs the joint line while point-contacting with it without simultaneously contacting with the joint line, resistance against the brush part 21 is remarkably reduced compared with a conventional case, and because the joint line is rubbed with the brush part 21 extending over the full length, resistance against the brush part 21 can be reduced without degrading the cleaning capacity, and the joint between walls can be smoothly cleaned.
