A method of manufacturing a roller turret cam index device including a roller turret cam and a roller turret which engage each other such that said roller turret cam and said roller turret are rotatable about respective two axes that are spaced apart from each other and intersect each other, said method comprising:
- a step of preparing a turret body having a plurality of mounting holes formed therein such that said mounting holes are arranged in a rotating direction of said turret body;
- a step of preparing a plurality of roller shafts each including a roller support portion on which said roller is rotatably mounted, and a stud portion which is eccentric with respect to said roller support portion;
- a preliminary roller turret assembling step of preparing a preliminary roller turret assembly wherein each of said roller shafts is rotatably fitted at said stud portion in a corresponding one of said mounting holes;
- a preliminary index device assembly step of preparing a preliminary index device, by assembling said preliminary roller turret assembly and said roller turret cam within a housing;
- an angular pitch adjusting step of adjusting an angular pitch of adjacent ones of said plurality of rollers of said preliminary roller turret assembly, by rotating the roller shafts;
- and
- a fixing step of fixing all of said roller shafts to said turret body after said angular pitch adjusting step.
