PROBLEM TO BE SOLVED: To provide a centering rattle stopping device which can obtain strong clamp force even if having a mechanically simple structure, suppressing a wear of a component, and enduring use for a long period.SOLUTION: A centering rattle stopping device has first and second slide plates mounted with first and second V-shaped blocks clamping work; first and second sliding shafts which are coupled to the first and second slide plates to respectively slide that; and driving means which slides at least either one of the first or second sliding shafts. A link mechanism is composed of first and second arms respectively connected to first and second coupling pins engaged with the first and second sliding shafts; and a center arm which is respectively connected to the first and second arms through third and fourth coupling pins, and capable of rotating about a center axis. By operating the driving means, the first and second slide plates are moved to the center axis only by the same amount, with the link mechanism of the center arm. |
