ABSTRACT:
A predetermined number of sprags 21 are consecutively inserted into sprag pockets 45 in a boss 44 on a rotary index table by means of a sprag inserting section 50. Then, a ribbon spring 22 is fitted to the boss 44 by means of a ribbon-spring fitting section 50, and an outer retainer 23 is fitted to the boss 44 by means of an outer-retainer fitting section 70. At the same time, the boss 44 is continuously rotated to move the sprags 21 toward the radially outward side of the boss 44 by the centrifugal force acting in the sprags 21, thereby allowing the sprags 21 to be inserted and fitted into sprag inserting windows 28 and 30 of the ribbon spring 22 and the outer retainer 23. Further, an inner retainer 24 is fitted to the boss 44 by means of an inner-retainer fitting section 80 to insert and fit the sprags 21 into the sprag pockets 45 of the inner retainer 24.
