<p>PROBLEM TO BE SOLVED: To provide a grommet-expanding machine capable of stably expanding a long grommet for electric wire passing work. SOLUTION: The root part of an expanding claw 1, passed through a grommet and its front end, are supported by link mechanisms disposed in parallel. A cylinder actuator 5 interlockingly drive the link mechanisms 2, 3 to relatively move three expanding claws 1 supported by first, second and third links 8, 9 and so on to a radially expanded position and enlarge the grommet with the claw.</p> |
