A shock isolation structure applied in an optical disc drive is provided. The shock isolation structure includes a bottom portion, a top portion, and a neck portion jointing the bottom portion and the top portion. The portions have a through hole running through the top surface of the top portion and the bottom surface of the bottom portion along a run-through central line. In the neck portion, any ring-shaped cross section using the run-through central line as the normal has a first wall thickness on a first extension line starting from the run-through central line and extending towards the outer peripheral of the ring-shaped cross section, and has a second wall thickness on a second extension line starting from the run-through central line and extending towards the outer peripheral of the ring-shaped cross section. The first wall thickness is larger than the second wall thickness.
