PURPOSE:To prevent a shock of wave from being applied to an inner cable, by axially slidably providing each pulley, wound with the inner cable of handling and steering units, and screwing a steering screw of the steering unit to a steering pipe. CONSTITUTION:A steering wheel is mounted to one end of a driving shaft 4 in a handling unit 2, and an operating main shaft 5 is fitted to the other end and turned together with the shaft 4. A handling side pulley 6 is axially slidably fitted to the shaft 5 so as to turn with the shaft 5. An inner cable 9 is stopped to the pulley 6, and a guide 8 of the inner cable 9 covers the pulley 6. A driven pulley 13 is axially fitted slidably to a driven shaft 12 in a steering unit 10 so as to turn with the shaft 12, and the inner cable 9 is stopped to the shaft 12. A steering screw 14 is enclosed by a guide pipe 15 and screwed to a steering pipe 16 to which a steering rod is pivotally mounted. The both units 2, 10 are coupled through an inner cable tension adjusting device 21 by a conduction pipe 20 to which the inner cable 9 is inserted. A shock of wave is applied to the screw 14 but not transmitted to a speed increasing means 19, not resulting in the factor for extension of the inner cable 9. |
