Claims

[Scope of utility model registration request]

In a feed drive device consisting of a screw shaft supported at both ends and a driven body equipped with a nut that engages the screw shaft, a plurality of bearings are opposed to each other at an intermediate portion of the screw shaft and are attached to the screw shaft. A cam is attached to the driven body that is biased and contacts a cam follower attached to the bearing when the driven body passes, and pushes the bearing apart to allow the driven body to pass. Feed shaft vibration prevention device.
