PURPOSE: A quick-coupler device is provided to reduce the resistance of fluid in the coupler, and to easily couple a female coupler to a male coupler without a screw. CONSTITUTION: A quick-coupler device is composed of a female coupler(F), a male coupler(M), and a coupling unit(C) for coupling the female coupler to the male coupler. The female coupler includes a female valve cylinder(10), a valve shaft(40) movably installed in the female valve cylinder, a first sealing member(50) fixed to the valve shaft, a first stopper ring(90) fit into the female valve cylinder, a support member(70) for guiding and supporting the valve shaft, a valve spring(80) installed between the valve shaft and the support member and elastically supporting the valve shaft, and an O-ring(100) installed at the female valve cylinder. An insertion portion(23) is formed at one end of the male coupler, and is inserted into the female valve cylinder.
