A swimming assistance apparatus according to the present invention includes a base combined with a human body and a motor-driven pump provided in a base. The motor-driven pump has a water inlet and a water outlet to operate by a battery so as to generate water flow from the water inlet to the water outlet. Several kinds of structure can be used for the base. For example, a buoyant hull having a pair of grips at front sides and a controller adjacent to the grips, a base having a handle, the buoyancy of which is set little higher more than 0 and a belt detachably attached to a human body can be used for the base. The swimming assistance apparatus according to the present invention uses the motor-driven pump as driving source, so that the apparatus can be made smaller and lighter, and the apparatus can improve safety.

1. A swimming assistance apparatus comprising:a base adaptable to be combined with a human body; and a motor-driven pump provided in the base, the motor-driven pump has a water inlet and a water outlet to operate by a battery so as to generate water flow from the water inlet to the water outlet, wherein the motor-driven pump is an in-line motor-driven pump including: a cylindrical stator; a rotor provided inside of the stator, having an axial fan for feeding water from the water inlet to the water outlet; a first pressure chamber for transforming rotation kinetic energy with respect to water directing to the water outlet by the rotation of the axial fan to static pressure energy; a second pressure chamber disposed between the first pressure chamber and the water outlet, the first pressure chamber and the second pressure chamber are divided by a separator; and at least one guide hole provided in the separator to connect the first pressure chamber with the second pressure chamber.
