左方向（第１図において）に移動する。 3 and 4, reference numeral 21 denotes a counterbore (see FIG. 3), which is formed at the mouth end of the through hole 11 in the bearing member 13. This counterbore 21 is a place where a bush 23, which will be described later, is installed. 23 is a bushing, which is fixed by a fixing bolt 25 with the center of rotation a eccentric from the axis b.
It is installed in the counterbore portion 21 of the bearing member 13. This bush 23 can be rotated when the fixing bolt 25 is loosened, and cannot be rotated when the fixing bolt 25 is tightened. Reference numeral 27 denotes a bearing (corresponding to the rollers of this invention), which is externally fitted and fixed to the bush 23. This bearing 27 is in contact with the side surface of the shaft body 15, and its rotation axis (axis center) b is oblique with respect to the shaft center of the shaft body 15. The distance between the side surface of the shaft body 15 and the side surface of the bearing 27 can be adjusted by rotating the bush 23 around the fixing bolt 25. As a result, the side surface of the shaft body 15 and the side surface of the bearing 27 are smooth. You can choose which state you want to touch. And shaft body 1
When the shaft 15 is rotated in the direction of the arrow with the side surface of the bearing 27 in smooth contact with the side surface of the bearing 27, the bearing member 13 moves to the right (in FIG. 1) and rotates in the opposite direction of the arrow. When the bearing member 13 is moved, the bearing member 13 moves to the left (in FIG. 1).
