All DC60 ball bearings (28) except a handful of the remaining bearings (28a to 28c) are grouped. A number of bearings are divided along the inner circumferential wall surface (40) of the roller (30), and later the remaining ball bearings (28a to 28c) are distributed along the circumference or distance. And it has been inserted into the corresponding cam groove (48a to 48c) of cam (52), cam (52) has been rotated in direction, has been shown with arrow A to make the first to third press surface. (50a to 50c) of cam (52) presses the remaining ball bearing (28a to 28c) at the same time along the radial outward. Outside or across, into the corresponding gap (56a to 56c) between adjacent ball bearings (28). These are arranged along the inner circumference wall surface (40). All bearings (28) leave a number of remaining bearings (28a to 28c) arranged in groups.
