<P>PROBLEM TO BE SOLVED: To provide a power transmission device having stable torque cutting-off performance while suppressing an increase of cut-off torque by suppressing the appearance of corrosive organisms on a contact face between an extraction member and a member to which one end thereof is connected, with easy and inexpensive treatment. Ž<P>SOLUTION: The power transmission device is provided with: the extraction member to be extracted during cutting off torque; and a fastening member for extractively fastening one end of the extraction member to a driving side member or a driven side member when transmission torque exceeds a set value. Surface treatment is applied to the contact face of the driving side member or the driven side member with the extraction member to suppress the appearance of the corrosive organisms.
