Abstract: A hydraulic pilot valve consisting of a pair of pressure-reducing valves, wherein a stopper which can freely adjust maximum control inputs of operating levers (23, 24) of the hydraulic pilot valve is provided to make maximum pilot pressures output from the pair of pressure-reducing valves freely adjustable. Furthermore, in the hydraulic pilot valve, a stopper member for limiting a maximum control input of an operating lever is fixed to the operating levers (23, 24), so that an operating force during a maximum operation of an operating lever is received by the stopper member. Furthermore, in the hydraulic pilot valve, an erroneous operation due to vibrations and the like is prevented by a damper mechanism (50) interposed between a lever fixed to each of the operating levers (23, 24) and a main body (1) of the valve.
