ABSTRACT:
A wet type friction contact device comprises a non-driving member; a driving member which drives to the non-driving member; and fluid which is intervened between the non-driving member and driving member; wherein the coefficient of dynamic friction of the contact area between the non-driving member and the driving member is not less than 0.2. Therefore, the present invention provides a wet type friction contact device which secures a large amount of torque capacity compared with that of the conventional wet type contact device without bringing about large-size unit thereof and also without requiring disassembly and exchange thereof.
