PURPOSE:To constitute so that a holder does not stand in the carrying way of an object to be worked when a moving member goes backward, by making a holder supporting base for the object to be worked go forward and backward by the moving member which expands and contracts, and providing the holder on the holder supporting base so as to rise and fall easily. CONSTITUTION:When an oil pressure cylinder 4 is expanded, a moving member 6 goes forward, abuts on a holder 9, erects the holder 9, and advances a holder supporting base 8. By this operation, a holder tip 9a presses an object to be worked A, and makes it go along a positioning member 3. When the object to be worked is pressed, the moving member 6 is made to go backward. In this case, restoring force of a spring existing between the tip of the moving member 6 and a stopper 12 operates on the holder supporting base 8, and the holder supporting base 8 goes backward, as well. When the supporting base 8 goes backward by a constant extent and the stopper 12 abuts on a bearing member 7, the tip of the moving member 6 is separated from the holder 9 and the holder 9 falls down so that it does not stand in the carrying way of the object to be worked A. |
