Abstract: PURPOSE:To maintain the high vacuum by utilizing a permanent magnet and an electromagnet as a bearing while arranging them at the low vacuum side. CONSTITUTION:A rotary side permanent magnet (1-a) and a fixed side permanent magnet (1-b) are provided as an upper axial and passive magnetic bearing utilizing the repulsion force, and it is constructed such that the recovery force will function when the center axis of the magnet (1-a) is shifted against the center axis of the magnet (1-b) thus to hold the upper section of a rotary member to the center to be determined by the magnet (1-b). The movable range of the rotary member in the rotary axis is limited in such range as a1<a< a2 by means of mechanical bearings 9, 10 to apply the unilateral force on the rotary member continuously. The position in the direction of the rotary shaft is detected by a displacement sensor in the direction of the rotary shaft (4-b) and a displacement sensor target in the direction of the rotary shaft (4-a) thus to control the current flowing through an electromagnet for controlling the direction of the rotary shaft to the constant level where the rotary member will be between a1 and a2 continuously.
