The present invention relates to a mounting structure of a trembler for a hydraulic engine-mount which trembles while combined with a nozzle plate as hydraulic liquid flows into an upper liquid chamber and a lower liquid chamber which are separated by the nozzle plate. The mounting structure of a trembler for a hydraulic engine-mount comprises: a nozzle plate having an upper opening part intercommunicating with the upper liquid chamber and a lower opening part intercommunicating with the lower liquid chamber, and including a supporting part having a space inside; and a trembler mounted inside the supporting part, wherein the trembler has a shape of a ball. The present invention having the above-mentioned composition can solve the hanging problem of an existing membrane in the shape of a film by having a trembler in the shape of a ball. The present invention can also attenuate trembling in a low-frequency region by using the size and shape of the supporting part and the diameter value of the trembler as tuning factors, and can provide higher degrees of freedom in design.
