The present invention relates to a rectifying bearing for inputting or outputting a current to a revolving armature. More particularly, the present invention relates to a rectifying bearing of a rotation-type electric connecting function which reduces frication/abrasion and noise generated in an instantaneous contact between electrodes for applying electricity, and extends operation life. The rectifying bearing includes a housing; a first electrode fixed to the housing; second electrodes which are insulated from each other to surround the first electrode and are fixed to the circumference of the housing; a conductive inner rotation body which is rotatably installed to the first electrode and is electrically connected; and a roller part which comprises a conductive roller and a non-conductive roller which are rotatably arranged around the inner rotation body to be in contact with the second electrode. |
