A lifting structure is provided, which makes it possible to upwardly pull an object installed at the bottom of water, more reliably and at a high operation efficiency irrelevant to a state of the bottom of water. A lifting structure for lifting an object installed at a bottom of water comprises a lifting apparatus which has a lifting axis and which lifts the object along the lifting axis; a reaction force plate which has a bottom surface configured to press the bottom of water in a case that the object is lifted by the lifting apparatus; and a connecting portion which connects the lifting apparatus and the reaction force plate so that the bottom surface is rotatable with respect to the lifting axis.
