Abstract
In a rotary index device for a machine tool, in which the index position of, for example, a circular table is maintained by normally clamping a clamp disc with a clamping mechanism and in which, for example, the circular table is unclamped by an unclamping mechanism when an indexing operation is performed, the clamping mechanism includes a fixing portion, a resiliently deformable supporting portion, and an urging mechanism. The fixing portion is fixed to a housing of the rotary index device for the machine tool. One end of the supporting portion is secured to the fixing portion, and a pressing portion having a face that opposes the clamp disc is secured to the other end of the supporting member. The urging mechanism normally urges the supporting portion towards the clamp disc to realize a state in which the clamp disc is pressed by the pressing portion.
