Abstract
A submersible motor is given a relatively short axial length by arranging a member, at the portion which is on the lower end during use, to serve for transmitting radial torque as well as for transmitting thrust load. By such arrangement, the axial length normally required for the thrust bearing and radial bearing is made shorter.
