The present invention relates to an independent test device capable of an axis-inclined propeller cavitation test in a uniform flow. According to the present invention, the independent test device comprises: a large cavitation tunnel having an opening unit on an upper surface to insert an underwater body; a tubular trunk wall unit attached to the large cavitation tunnel in order for the opening unit to be located on an inner side of an end in a longitudinal direction; and an installation structure located in the trunk wall unit, changing an angle in a longitudinal direction of the underwater body in order for a longitudinal axis of the underwater body and the longitudinal axis of the large cavitation tunnel to be at a predetermined angle with each other. The independent test device capable of the axis-inclined propeller cavitation test in a uniform flow is able to control an axis inclination of the underwater body using a rotation member installed in the installation structure and is able to maintain the axis inclination during a cavitation test using an angle control nut installed in the rotation member, an angle fixing nut, and a power lock.
