摘要： 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.
