PURPOSE: A neck structure for a reservoir tank is provided to allow for re-utilization of material when the reservoir tank is discarded, while permitting the capacity of coolant to be checked through naked eyes of a user. CONSTITUTION: A neck structure comprises a body(21) having a neck mounting hole(22) formed at the top surface of a container for storage of coolant, and a bolt hole(23) formed at both sides of the neck mounting hole; a tank neck(30) having both sides where a bracket(31) to be fixed into the bolt hole through a bolt(50) is arranged, a center where a mounting portion(32) to be inserted into the neck mounting hole is formed, a cap coupling portion(33) extended upward, and a discharge path(36) formed at one side surface of the cap coupling portion so as to discharge the coolant from the reservoir tank; and an O-ring(40) fitted between the tank neck and the neck mounting hole so as to prevent a leakage of coolant.
