Abstract
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.
