A liquid pump has a sealing mechanism utilizing magnets. The sealing mechanism
includes an annular rotating seal attached to the lower surface of a rotary base
member fixed to the motor rotating shaft. Additionally, a flexible stationary seal
is joined and separated with respect to the rotating seal. Movable magnets are
disposed on the rotary base and are adapted to be displaced by centrifugal force
due to a rotation of the rotary base member. A stationary magnet is disposed on
the upper-surface side of a vertical sliding member to which the flexible stationary
seal is fixed. The flexible stationary seal utilized has a cylindrical body. At
the upper and lower end portions and the side surface portion, connecting portions
to the stationary and movable members are formed. The middle portion has an elastic
portion is formed on it.
