PROBLEM TO BE SOLVED: To provide a propeller shaft supporting structure capable of significantly retaining a sealing effect without corrosion caused by brine and the like by applying resin-employing constitution to a flange for covering the opening of the inner ring of an annular supporting member for supporting a center bearing at the interior of the inner ring, and easily producing a stopper piece at lower costs. SOLUTION: In a propeller shaft supporting structure, an annular supporting member 10 interconnecting an inner ring 11 to an outer ring 12 through an elastic member 13 journals a propeller shaft 1 through a center bearing 5 at the interior of the inner ring. Where, a stopper piece 20 made of a metal and formed in a flange-free simple cylindrical shape is press fitted the propeller shaft 1 and is abutted to the inner lace 5a of the center bearing 5, positioning the center bearing 5 at a given position in the axial direction for fixing. A flange 25 made of a resin is fittingly engaged with the extremity of the stopper piece 20. The flange 25 covers the opening of the inner ring 11.
