Abstract:
1. A cleaning device comprising: a first cleaning member provided at a first side of a curved grid electrode plate that is curved in a short-side direction, the first cleaning member being pressed against the curved grid electrode plate to clean the first side of the curved grid electrode plate; a receiving member provided at a second side of the curved grid electrode plate, the receiving member receiving a pressing load applied by the first cleaning member; and a moving unit that moves the first cleaning member and the receiving member in a long-side direction of the curved grid electrode plate, wherein the first cleaning member and the receiving member are formed such that a pressure based on the load that is applied to an end portion of the curved grid electrode plate in the short-side direction is higher than a pressure based on the load that is applied to a central portion of the curved grid electrode plate in the short-side direction.
