PROBLEM TO BE SOLVED: To provide a gripper of a conveyer capable of both holding a plurality of kinds of workpieces or the like different in size and shape, and avoiding interference with a peripheral device.SOLUTION: A gripper 5 is disposed on a conveyer and comprises a pair of holding portions 51 for holding a cylindrical workpiece, which engage with a holding guide 53. The holding guide 53 has a linear parallel guide portion 531 for moving the pair of holding portions 51 parallel to each other, and a pair of curved open guide portions 532 for opening distal ends of the pair of holding portions 51 to both sides at both end portions of the parallel guide portion 531. The pair of holding portions 51 can move to a holding position 511 where they come closer to each other along the parallel guide portion 531 to hold the cylindrical workpiece and a retreat position where the distal ends retreat separately from each other along the open guide portions 532. |
