Abstract
A push-bar indexing device that, when an index table is rotated by a specific angle, the table is accurately stopped to accurately index a workpiece. Each time a push bar is moved, a stopper is moved to a predetermined position by excessive relative movement between a spindle and a main table. An engagement member is operatively associated with the index table, which causes the engagement member to be rotated by a specific angle each time the index table is rotated. This allows the engagement member to be engaged with the stopper of a predetermined position, causing the index table to be stopped by the stopper.
