Abstract
A predetermined number of sprags are consecutively inserted into sprag pockets in a boss on a rotary index table by a sprag inserting section . Then, a ribbon spring is fitted to the boss by a ribbon-spring fitting section , and an outer retainer is fitted thereto by an outer-retainer fitting section . At the same time, the boss is continuously rotated to move the sprags radially outward by centrifugal force, thereby allowing the sprags to be inserted and fitted into sprag inserting windows and of the ribbon spring and the outer retainer . Further, an inner retainer is fitted to the boss by an inner-retainer fitting section to insert and fit the sprags into the sprag pockets of the inner retainer
