PROBLEM TO BE SOLVED: To damp hydraulic pulsation within a system by providing inside one of the quick disconnect coupling member a surface that communicates with hydraulic fluid passage means of one of the coupling members, and further disposing a diaphragm that responds to the pulsation of the hydraulic fluid inside the conduit assembly. SOLUTION: A diaphragm 72 is disposed inside a main body of a female coupling member 44. An inner surface 72c of the diaphragm 72 fluidly communicates, through a bore 56a of a disc, with hydraulic fluid which moves via a hydraulic passage that is defined in the female coupling member 44 by a center axis passage 54d and a radial passage 54i. With this construction, the diaphragm 72 weakens the vibration of the hydraulic fluid or the pulsation transmitted from a crankshaft to a clutch pedal. Consequently, the beating of the pedal and the beating of the clutch pedal are minimized or eliminated. At the same time, the vibration felt by a driver from the clutch pedal is eliminated or minimized.
