Abstract
A variable discharge width device includes a hollow outer cylindrical part where inside and outside thereof communicate with each other via a discharge port, and an inner cylindrical part rotatable inside the outer cylindrical part along a circumferential wall of the outer cylindrical part. The inner cylindrical part can introduce fluid thereinto, and has a circumferential part opening formed in the circumferential wall so that inside and outside of the inner cylindrical part communicate with each other. The circumferential part opening is formed so that an opening width thereof changes in the circumferential direction of the inner cylindrical part. The variable discharge width device is capable of discharging the fluid introduced into the inner cylindrical part, from a communicating area formed by intersecting the circumferential part opening and the discharge port.
