To provide an electric pump capable of increasing the straight advance force and acceleration of a fluid.
Double reversely rotating vanes are rotated reverse to each other by the drive force of a driving source. Also, a forward shaftless first reversely rotating vane and a shaftless second reversely rotating vane located at the rear of the first reversely rotating vane are formed of cylindrical bodies having hollow parts guiding a fluid in one direction from their one end faces to the other end faces and wide vane bodies having spiral outer peripheral ends fixed airtight to the inner peripheral surfaces of the cylindrical bodies, respectively. The second reversely rotating vanes accept forward entrainment flows produced on the first reversely rotating vanes, and force-feed it as rear entrainment flows while correcting in a reverse direction.
