Abstract
PURPOSE:To draw an operating wire to a sufficient length by a small-scale lightweight apparatus, by providing a guide means for guiding the movement of a connection piece when a drive piece is revolved by an operating means and increasing the traction quantity of an operating wire as compared with the revolving quantity of the drive piece. CONSTITUTION:The operating wire 11 mounted to the leading end of a curved part 2 at one end thereof is drawn by revolving an operating lever 6 to bend the curved part 2 and the moving quantity of the connection pin 15 connecting a connection arm 13 and a wire stopper 10 (that is, the movement quantity of the operating wire 11) is made larger than that of the connection pin 15 at the leading end of the drive arm 12 to a large extent. By constituting a curving operating apparatus of a link mechanism, the stroke of the operating wire 11 is largely increased by a small apparatus. The magnitude of the stroke of the operating wire 11 to the angle of rotation of the operating lever is appropriately set by changing the distance from the center of a rotary shaft 7 to a recessed groove 9, the distance up to the connection pin 14 and the length of the connection arm 13.
