PROBLEM TO BE SOLVED: To rapidly change setting of waiting positions of an upper claw and a lower claw corresponding to the thickness of a work, in a grip mechanism used for conveying a work. SOLUTION: Waiting position contacts P1, P2 for a pair of upper claw and lower claw to be opened or closed by a cam mechanism are set on a large diameter vertex and on the small diameter vertex of a cam 21a for the upper claw. When the work is thick, the upper claw is made to wait at the waiting position contact for the upper claw set to the large diameter vertex; while when the work is thin, the waiting position contact P2 for the upper claw set to the small diameter vertex is waited so that the upper claw can be opened or closed at the gripping time of the shortest upper claw stroke, in response to the thickness of the work.
