<p>PURPOSE:To perform connection of two systems in a manner that the neutral position of a machine system coincides with that of a hydraulic system by assembling the support part on the car body side of a displacement transmitting means after the fulcrum on the rear wheel steering shaft side of the displacement transmitting means is set to a neutral position, and thereafter, assembling a hydraulic switch valve. CONSTITUTION:In assembly of a machine system to displace a rear wheel steering shaft 13 and a hydraulic system to assist displacement thereof, after the engaging end part D side of a cross lever 14a is inserted in a swing seal 56, an output rod member 16 and a yoke assembly 18 are assembled, and the angle positions of the yoke assembly 18 and an input shaft 26 are respectively regulated to a neutral position. The rear wheel steering shaft 13 engaged with an engaging end part B of the cross lever 14a is assembled to decide the neutral position of the rear wheel steering shaft 13. Thereafter, after a support 38 is engaged with an engaging end part C of the cross lever 14a, it is secured to a car body. After, as noted above, regulation of the neutral position of the machine system and a work to fix fulcrums A-C of the cross lever 14a are completed, a valve spool 42 of a hydraulic switching valve 15 is engaged with the engaging end part C of the valve spool 42.</p> |
