Abstract

PURPOSE: To improve the transmission of movement in a straight direction by transmitting a movement from a location outside a vacuum housing to a mechanism inside the vacuum housing by virtue of mutual magnetic adhesive forces of ringlike magnets attached on both the inside and outside surface of a partition wall.
CONSTITUTION: For forming a rotation power transmission section A, an external S-pole permanent magnet 3 having a flange 1 united with a yoke 4 and an internal parts connected with a driven unit 10 are provided respectively on the external surface and the internal surface of a vacuum partition wall 6 which has a fitting flange 1 to a vacuum equipment at one end. A straight power transmission section B is put aside the section A and consists of an external ringlike permanent magnet 8 and an internal ringlike permanent magnet 9. A nonmagnetic spacer 11 for interferencing a magnetic field is interposed between both the transmission sections A, B. Both of the permanent magnets 8, 9 as shown in the magnification, are disposed for having magnetic poles in their feed directions, thereby obtaining the magnetic adhesive forces.
