PROBLEM TO BE SOLVED: To provide a pressure variation-cushioning mechanism which can secure a circulation performance of an ink guide core.SOLUTION: A pressure variation-cushioning mechanism 180 has a cushioning space K connected to a paint tank 140 to cushion a pressure variation of the paint tank 140 by circulation of paint and air between the paint tank 140 and the cushioning space K. The pressure variation-cushioning mechanism 180 includes a pressure variation-cushioning structure, a body cylinder 170T, and an engaging part 170B. The pressure variation-cushioning mechanism is a first cushioning space-forming member 183 that, for example, forms a cushioning space K1 having a predetermined channel or a second cushioning space-forming member 184 that forms a cushioning space K2 having a predetermined channel. The body cylinder 170T supports a first core part in a paint feeder 160 that feeds the paint from the paint tank 140 to a brush 120. The engaging part 170B engages a second core part of the paint feeder 160. The pressure variation-cushioning mechanism 180 is provided in the body cylinder 170T. |
