An apparatus for regulating a contact pressure of a circuit breaker is provided to easily regulate a contact pressure by regulating a contact pressure of both contactors. An apparatus for regulating a contact pressure of a circuit breaker comprises the followings: a rotation axis(6) rotating according to an opening/closing operation of a circuit breaker(1); a rotation axis lever(7) rotating together with the rotation axis, and adhered to the rotation axis; a connection link(10) in which one end is connected to the rotation axis lever through a middle link(8) and the other end is axis-supported by an operation supporter(9); and a main circuit connection part giving a contact pressure to both contactors, and having an insulation rod(12), a wipe link(13), and contact pressure spring(14).
