    • PROBLEM TO BE SOLVED: To provide a coupling for connecting hydraulic ducts which can be assembled easily and have a long life by being held with lock elements fixed. SOLUTION: This coupling for connecting the hydraulic ducts according to the present invention comprises a first coupling element 1, a second coupling element 2 which can be inserted into a receptacle 3, and a non-locking element 10 arranged in an annular groove 9, held by the annular groove 9 at an end 11 in the first longitudinal direction and movably supported between a locked position and a released position and in the state where the coupling elements are connected, by inserting the second coupling element 2 into the receptacle 3, each of locking elements 10 is moved from the locked position to the released position, the coupling can be moved on the second coupling element 2 between the locked position and the released position and holding each of the locking elements 10 within the annular groove 9 at a second axial directional end, and by moving a non-locking sleeve 28 from the lock position to the released position, the locking element 10 is moved from the locked position to the released position.

    • PROBLEM TO BE SOLVED: To allow synchronization between a position of a steering drive and a position of a steering angle generator, by slight labor and time for constitution and manufacture. SOLUTION: The steering angle generator 2 is connected to a steering valve 3, the steering valve controls connection among the steering drive 11, a pressure medium source 5 and a tank 9 in response to an operation of the steering angle generator, and a correction device 15 allows the synchronization between the position of the steering drive 11 and the position of the steering angle generator 2, when the steering drive 11 or the steering angle generator 2 is within a reference range, and when the position of the steering drive 11 or the position of the steering angle generator 2 has a deviation from the reference range.
