Claims

[Claims for Utility Model Registration] (1) It has a long male threaded shaft and a female thread that is screwed onto the male threaded shaft, and by rotationally driving either the male threaded shaft or the female thread, the horizontal In a device for horizontally moving a moving object, a support means for supporting the male screw shaft is disposed in a movable range of the horizontally moving object so as to be movable up and down, and detecting when the horizontally moving object approaches the supporting means. The horizontally moving object is provided with a detection means for detecting the support means, and when the horizontally moving object approaches the support means, the support means is lowered, and when the object moves away from the object, the support means is brought into contact with the male threaded shaft. Rotational run-out prevention device for screw shafts used to drive moving objects. (2) Preventing rotational runout of a screw shaft for driving a horizontally moving object as set forth in claim 1, wherein the support means includes a hydraulic cylinder and the detection means includes a hydraulic switching valve. Device. (3) Utility model registration claim 1, in which the support means includes a spring, and the detection means includes a dog that presses the spring.
A device for preventing rotational runout of a screw shaft for driving a horizontally moving object as described in 2.
