This positioning pin has a double structure, and a plurality of slits are formed radially from the center between the tip and the middle part, approximately parallel to the axial direction, and the tip is inside the inner diameter of the outer cylinder with a reduced diameter. A positioning pin characterized by having a means for expanding the inner diameter. (2) The means for expanding the inner diameter of the outer cylinder is an inner cylinder that is driven in the axial direction of the outer cylinder by a drive source, Claim 1
Locating pin as described in section. (3) The positioning pin according to claim 1 or 2, wherein a tapered surface is formed on the outer periphery of the inner cylinder so that the diameter decreases toward the tip. (4) The positioning pin according to claim 1 or 2, wherein a protrusion is formed on the outer periphery of the inner cylinder. (5) The utility model according to claim 1, wherein the means for expanding the inner diameter of the outer cylinder is a bag-like member made of an elastic member whose diameter is expanded by injection of fluid. Locating pin.
