This invention relates to an assembling structure of water conduction device for mist maker in which the water conduction device comprises a mounting seat and a capillary water-conduction fiber; resilient pieces being provided at both sides of the mounting seat, which have engaging means provided thereon; a mounting hole being further provided within the housing of the mist maker, in which the mounting seat of the water conduction device is assembled, the engaging means provided on the resilient pieces of the mounting seat being interlocked on the wall face of the assembling hole of the housing such that the water conduction device can be mounted within the housing of the mist maker. If the water conduction device is to be replaced, two resilient pieces has to be pressed such that the engaging means are released from the interlocking with the wall face of the assembling hole, then the water conduction device can be detached for replacement.
