タ。 A double cylindrical rotating shaft is rotatably fixed to a support and has two cylinders arranged concentrically with respect to the rotating shaft. Two external input/output ports are opened in the support part to lead each to the gap between the cylinders, and two ring-shaped permanent magnets are fixed to the support part facing the edges of the two cylinders at the ends of the double cylinder rotating shaft. and,
two ring-shaped magnetic pole pieces that transmit magnetic force to the magnetic fluid while separating the ring-shaped permanent magnet and the magnetic fluid;
A magnetic fluid that is attracted by magnetic force and seals the gap between the end of the double cylindrical rotating shaft and the two ring-shaped magnetic pole pieces, and a magnetic fluid that seals the gap between the double cylindrical rotating shaft, the external input/output port, the ring-shaped permanent magnet, and the ring-shaped magnetic pole pieces. An actuator characterized by having a support part that maintains and fixes a positional relationship.
