Abstract:
A diffuser-type endplate propeller driving a hull and including a propeller hub a plurality of blades is provided. The propeller hub has an axis of rotation and is connected to a transmission shaft of the hull. The blade has a blade-body and an endplate. The blade-body is connected to the propeller hub and extends outward from the propeller hub to the corresponding endplate, the endplate bends from the corresponding blade-body to extend towards a stern of the hull, and the endplate has a leading edge and a trailing edge. A cylindrical surface is imaginarily formed by the leading edges while the diffuser-type endplate propeller is rotated about the axis. Each of the endplates has a first tangent plane at the leading edge thereof, the cylindrical surface has a second tangent plane at the leading edge. An included angle is measured from the second tangent plane to the first tangent plane.

Claim (Index 3):
The diffuser-type endplate propeller according to  claim 1 , wherein the leading edge keeps a first distance from the axis of the propeller hub, the trailing edge keeps a second distance from the axis of the propeller hub, and the first distance is shorter than the second distance.
