Zusammenfassung:	The present invention provides a resistance reduction apparatus for a moon pool. The resistance reduction apparatus for a moon pool comprises: a pair of inclined rails which are fixed to the left and right surfaces of a moon pool, respectively, to have an inclination becoming higher frontward and are extended from the rear surface of the moon pool through the top of a lower deck located in the front of the moon pool; a sliding plate which has left and right ends coupled to the rails to be slid, respectively; and a towing unit which pulls or releases the sliding plate. 본 발명은, 앞쪽으로 갈수록 높아지는 경사 자세를 취하며 문풀의 좌측면 및 우측면에 각각 고정되고, 상기 문풀의 뒷면으로부터 상기 문풀의 앞쪽에 위치하는 하갑판의 상부를 지나며 연장하는 한 쌍의 경사 레일; 상기 한 쌍의 경사 레일에 미끄럼 가능하게 각각 결합된 좌단 및 우단을 갖는 미끄럼판; 및 상기 미끄럼판을 당기거나 놓아주기 위한 견인 수단;을 포함하는 문풀용 저항 감소 장치를 제공한다.
