<p>PURPOSE: To precisely operate a strap by continuously or stepwise decreasing a thickness of the strap from the end part carrying a gripper toward the other end and securing appropriate toughness and flexibility at a working place. CONSTITUTION: Toward the opposite side from the neighborhood of the end part carrying the gripper of a gripper strap, at least in a part of the strap cross section, the thickness of the strap is continuously/uniformly or discontinuously/stepwise decreased, respectively, appropriate toughness is secured for the part requiring a high guiding precision, and appropriate flexibility is secured for the part engaging to a gear.</p> |
