PROBLEM TO BE SOLVED: To provide a fluid pressurization device whose operability and convenience have been improved.SOLUTION: A fluid pressurization device 10 for pressuring fluid includes a housing 20 in which an accommodation part 23 for accommodating fluid is formed inside, and a port part 25 which is communicated with the accommodation part 23 and is opened to the outside is formed, a plunger 30 which can move in an axial direction in the housing 20, pressurizes or depressurizes the fluid in the accommodation part 23, and causes the fluid to flow into/out of the port part 25, a regulation part 40 disposed in the housing 20 for regulating the movement of the plunger 30 with respect to the housing 20, and an auxiliary part 50 for moving the plunger 30 in a state that the movement of the plunger 30 is regulated by the regulation part 40. A regulation operation part 41 for operating the regulation part 40 and an auxiliary operation part 51 for operating the auxiliary part 50 are located on the further tip side from a position on the most proximal side in a range that can accommodate the fluid of the accommodation part 23.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】操作性および利便性が向上する流体加圧装置を提供する。【解決手段】流体を加圧するための流体加圧装置10であって、流体を収容可能な収容部23が内部に形成されるとともに収容部23に連通して外部へ開口するポート部25が形成されたハウジング20と、ハウジング20内を軸方向へ移動可能であって収容部23内の流体を加圧または減圧させてポート部25から流入出させるプランジャー30と、ハウジング20に設けられてハウジング20に対するプランジャー30の移動を規制可能な規制部40と、規制部40によりプランジャー30の移動を規制した状態でプランジャー30を移動させる補助部50と、を有し、規制部40を操作する規制操作部41および補助部50を操作する補助操作部51は、収容部23の流体を収容可能な範囲の最も基端側の位置よりも先端側に位置する。【選択図】図2
