Zusammenfassung: | To provide a finger pump that suppresses generation of noise and vibration.SOLUTION: A finger pump includes: a frame boy 261 that has a pair of walls 266 and 267 facing to each other in a first direction 310; and a plurality of pressing parts 271 that are aligned in a second direction 320 orthogonal to the first direction 310 and disposed between the pair of walls 266 and 267, and reciprocates in a third direction 330 orthogonal to the first direction 310 and the second direction 320 to press a tube. A first gap 342 is provided between the wall 266 and the pressing parts 271 and between the wall 267 and the pressing parts. A second gap 341 is provided between adjacent pressing parts 271. The first gap 342 in the first direction 310 is smaller than the second gap 341 in the second direction 320.SELECTED DRAWING: Figure 7
【課題】騒音または振動の発生が抑制されるフィンガーポンプ、を提供する。【解決手段】フィンガーポンプは、第1方向310において対向する一対の壁部266,267を有するフレーム体261と、第1方向310と直交する第2方向320に並び、一対の壁部266,267の間に設けられ、第1方向310および第2方向320と直交する第3方向330に往復移動することによって、チューブを押圧する複数の押し子271とを備える。各壁部266,267と、複数の押し子271との間には、第1隙間342が設けられ、隣り合う押し子271の間には、第2隙間341が設けられる。第1方向310における第1隙間342の大きさは、第2方向320における第2隙間341の大きさよりも小さい。【選択図】図7 |
