る。(Means for Solving the Problems) In order to solve the problems caused by the occurrence of discharge phenomenon in the rotary support part according to the above-mentioned prior art, the present invention is made of a metal plate and has a substantially L-shaped cross section. a reinforcing ring having a shape and being fitted onto either the housing or the shaft passing through the housing; and a reinforcing ring made of a rubber-like elastic material and adhesively bonded to the end of the reinforcing ring to fit the housing and the shaft. An oil seal having a seal piece that elastically contacts the other circumferential surface is reinforced by arranging a conductive piece that is joined to a reinforcing ring and elastically contacts the sliding circumferential surface of the seal piece. The ring and conductive piece form a conductive circuit between the housing and the shaft. The conductive piece can be made by punching a copper plate or the like into a snake's eye shape and having multiple slits radially on the sliding side, or made by braiding thin metal wires into a ring shape.
A ring-shaped material made of a rubber-like elastic material mixed with metal fibers, carbon fibers, etc. is used.
