PURPOSE: A structure for preventing wear of a Wankel type compressor is provided to prevent wear of a triangular rotor and an inner wall of a cylinder, pressure loss due to a gap formed by the wear, and noise due to friction between the rotor and the cylinder by installing a sealing member on a corner of the rotor for elastic action preventing wear due to the friction between the rotor and the inner wall of the cylinder. CONSTITUTION: Sealing members(20) are installed to corners of a rotor(11) to prevent wear of the rotor and an inner wall of a cylinder due to friction. Sealing member insertion holes(17) are formed on the corners of the rotor to allow the sealing members to be inserted and fixed thereto. The sealing member comprises a cylindrical sealing body(21) abraded by friction with the inner wall of the cylinder as the rotor rotates to prevent direct friction between the rotor and the inner wall of the cylinder; and a spring(22) fixed to a bottom of the sealing body to protrude the sealing body abraded by friction with the inner wall of the cylinder due to rotation of the rotor so that the sealing body always contacts with the inner wall of the cylinder.
