PURPOSE:To perform lever operation accurately so as to improve lever operating feeling by providing an operating lever operable in both longitudinal and lateral directions from the neutral position at a lever supporting member for actuating the changeover of a brake control valve. CONSTITUTION:A lever supporting member 6 integral with an operating lever 7 is tiltingly rotated only in the lateral direction against a fitting rotary body 3 so as to actuate the changeover of a brake control valve integral with the fitting rotary body. Accordingly, when the operating lever 7 is laterally tilted, the lever supporting member 6 integral with the operating lever 7 directly actuates the changeover of the brake control valve 5. In addition, as this lever supporting member 6 is rotated in the longitudinal direction integrally with the brake control valve 5 integral with the fitting rotary body 3, dislocation in the positional relation between the lever supporting member 6 and the brake control valve 5 is not generated, and thereby the changeover operation of the brake control valve 5 is performed accurately corresponding to the lateral tilting of the operating lever 7, thus performing the gang control of the steering brake 4. Accordingly, lever operating feeling can be improved. |
