摘要：

PROBLEM TO BE SOLVED: To provide a fluid feeder capable of both feeding and drawing-in of fluid by a same pipe line and an endoscope device.

SOLUTION: Residual water after pressing a press part at the upper end of a switch shaft 36 forming a spray switch to simultaneously carry out air sending and water sending to remove deposits on the outer surface of an objective lens and clean the lens is increased after the operation in a state wherein a space 35 set on the bottom part of the spray switch communicates with a water sending pipe line in a process of returning the switch shaft 36 upward by the elastic force of a spring. Thus the residual water is drawn in from the tip end of the water sending pipe line by the negative pressure produced in the space 35 and removed.
