SOLUTION: In a turnbuckle T, rear ends of a pair of threaded rods 20 and 30 are screwed to a right screw and a left screw formed at both ends of a nut 1 respectively. An end of the threaded rod 20 is a fixed pin 2 attached to a fixed body 5. An end of the other threaded rod 30 is jointed to a movable arm 7 rotatable around a fulcrum pin 6 via the movable pin 3. Rotating the nut 1 of the turnbuckle 7 dislocates a rotating wheel 8 installed at the arm end of the movable arm 7. COPYRIGHT: (C)2005,JPO&NCIPI
