A coarse positioning structure used for a mounting member (3) and a mounted member (1), and a washing machine, for resolving a problem of a large error arising upon performing coarse positioning matching between a mounted member (1) and a mounting member (3). The coarse positioning structure comprises an engaging hook (2) on the mounted member (1) and an engaging hole (31) on the mounting member (3). A fastening block (4), fixedly connecting the engaging hook (2) and the engaging hole (31), is disposed on at least a side surface of the engaging hook (2). The washing machine comprises the coarse positioning structure used for the mounting member (3) and the mounted member (1). The fastening block (4) disposed on the engaging hook (2) fixedly connects the engaging hook (2) and the engaging hole (31), such that the gap between the engaging hook (2) and the engaging hole (31) becomes small, further reducing the range of action of the mounted member (1), increasing the precision of the coarse positioning match bet
