<p>The The present invention discloses an underwater pump which is characterized by mounting a a stationary flexible-piece-winding preventing member such as a stationary sleeve on the outer periphery of the portion of the rotating shaft of the rotary motor where the rotating head such as the agitator is mounted. Due to such construction, the winding or adhesion of the flexible piece to the rotaryhead mounting portion can be effectively prevented.</p> |
