| description | PURPOSE:To provide the subject device prolonged in life, having a long stroke and reduced in its external dead space by integrally connecting the end part on a vacuum side of a rotary shaft to the screw shaft part of the ball screw arranged in an outside pipe and integrally connecting the base end part of the straight advance shaft pipe engaged with the inner surface of the outside pipe in a non-rotatable manner and allowing its leading end part to protrude from a flange to a nut part. CONSTITUTION:An outward flange 11 is provided to the open left end of an elongated outside pipe 10 in order to connect the outside pipe 10 to a vacuum container in an airtight state and a rotary shaft 12 pierces the right closed end of the outside pipe 10 through a radial bearing 13 and a seal member 14. The right end of the screw shaft part 15a of the ball screw 15 received in the outside pipe 10 is integrally connected to the left end of the rotary shaft 12 to be extended up to the outward flange 11. The nut part 15b of the ball screw 15 straightly advances under vacuum by the rotation of the rotary shaft 12 and a straight advance shaft pipe 16 extends and contracts with respect to the screw shaft part 15a of the ball screw 15 to be able to advance straightly. |
