Patent ID: 8499439

Claim:
A positioning apparatus for a thin plate material having a positioning hole, comprising: a pilot holder having a hold face; a positioning pin having a tapered tip and supported by the pilot holder so that the tapered tip protrudes from the hold face of the pilot holder; a pad having a pad face that opposes the hold face of the pilot holder; a movable member having a stop face that opposes the positioning pin and a relief hole for avoiding the tapered tip of the positioning pin from hitting the stop face, the movable member resiliently supported on the pad so that the movable member is vertically movable; the pilot holder and the pad in which the thin plate material is set between the hold face and the pad face relatively moving to insert the tapered tip of the positioning pin into the positioning hole of the thin plate material to be engaged with the tapered tip at the position of the relief hole, thereby positioning the thin plate material in an in-plane direction; and the stop face of the movable member being flush with or protruding from the pad face of the pad.
