Claims

[Scope of utility model registration request]

A linear roller 7 having a rack 3 and rotatable at one end
A slidable rack shaft 2 to which a rack shaft 2 is attached, a pair of idle gears 4a and 4b that mesh with the rack 3 of the rack shaft 2, and a driven gear 5a that rotates while meshing with the idle gears 4a and 4b, respectively. , 5b, and connecting pins 9a, 9 to the driven gears 5a, 5b, respectively.
a pair of swing arms 6a and 6b, which are rotatably disposed via the shaft 2 and have rotatable arm rollers 8a and 8b attached to their tips, respectively; and a drive device 15 that drives the rack shaft 2. Consisting of
The moving distance of the straight roller 7 and the pair of arm rollers 8a, 8b with respect to the center of the workpiece 16 to be stabilized is determined by the swing arms 6a, 6b and the driven gear 5.
