To solve the problem on a conventional roller gear cam which requires very hard work for machining and special machine and tool for machining, and provide a intermittently rotating roller gear cam as required.

Driven rollers 8 for engaging a cam 4 of a driving shaft 5 are radially and axially supported at predetermined intervals on the outer periphery edge of a driven spider 2. The cam 4 spirally and peripherally provided on the driving shaft 5 has an intermittent stop portion 19 peripherally provided in the same inclination as that of a center line between the adjacent driven rollers 8 and an intermittent feed portion 18 peripherally provided in inclination to the center line between the adjacent driven rollers 8. The intermittent stop portion 19 is provided with slopes 19a, 19b having press contact in a wedged manner between the adjacent driven rollers 8.
