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