<p>The purpose of the invention is to provide a variable discharge width device which hardly causes a fluctuation in the discharge pressure even if a discharge width is changed, and to provide an applying device provided with the variable discharge width device. A variable discharge width device 100 includes a hollow outer cylindrical part 112 where inside and outside thereof communicate with each other via a discharge port 116, and an inner cylindrical part 130 rotatable inside the outer cylindrical part 112 along a circumferential wall of the outer cylindrical part. The inner cylindrical part 130 can introduce fluid thereinto, and has a circumferential part opening 138 formed in the circumferential wall 136 so that inside and outside of the inner cylindrical part 130 communicate with each other. The circumferential part opening 138 is formed so that an opening width thereof changes in the circumferential direction of the inner cylindrical part. The variable discharge width device 100 is capable of discharging the fluid introduced into the inner cylindrical part 130, from a communicating area 148 formed by intersecting the circumferential part opening 138 and the discharge port 116.</p> |
