| description | To provide a flow rate control device which can substantially-constantly maintain a flow rate of fluid injected into an organism while being simple in a constitution.SOLUTION: A flow rate control device 1 comprises a flow rate adjustment chamber 10 in which fluid FL supplied from a fluid supply port 12 is discharged from a fluid discharge port 14, and a float 20 whose gravity is set smaller than the gravity of the fluid FL, and which has a fluid receiving face 23 for receiving the dynamic pressure of the fluid FL which flows in from the fluid supply port 12. A flow passage 30 of the fluid FL is formed of a clearance which is sandwiched between an outer surface 22 of the float 20 and an inner surface 18 of the flow rate adjustment chamber 10. A flow rate regulation part 33 which is constituted so that the float 20 is descended and the clearance GW is narrowed in the case of (D+mg)>B, and the float 20 is ascended and the clearance GW is expanded in the case of (D+mg) |
