PROBLEM TO BE SOLVED: To provide a magnetic instillation stopper allowing the repeated use of a magnet unit by facilitating the attachment and detachment of the magnet unit to and from a drip vessel. SOLUTION: This magnetic instillation stopper comprises the drip vessel 1 for housing a liquid; a float valve 10 liftably provided within the vessel; and a valve seat 20 provided inside the vessel, with a passage blocked by the float valve 10. A float-side permanent magnet 12 having magnetic poles on upper and lower end surfaces is provided on the float valve 10, and a magnetic unit 30 having a permanent magnet group for magnetically attracting the float-side permanent magnet 12 to allow the float valve 10 to abut on the valve seat 20 is provided to surround the circumference of the vessel 1. The magnet unit 30 comprises a pair of unit split bodies for holding each at least one permanent magnet openably and closably connected through a hinge part 34. |
