PROBLEM TO BE SOLVED: To provide a submerged actuator that enables bidirectional drive and a submersible having the submerged actuator.SOLUTION: A submerged actuator 1A comprises: a housing 11 immersed in water; a cylinder chamber 12 formed in the interior of the housing; a piston 13 slidably accommodated in the cylinder chamber to divide the cylinder chamber into a first pressure receiving chamber 17 and a second pressure receiving chamber 18; a rod 14 extending from the piston to the side of the first pressure receiving chamber to penetrate the housing; an escape chamber 31 formed in the interior of the housing, in which the internal pressure is kept lower than the external water pressure of the housing; and a changeover device having a first switch-over part for switching communication/blockage between the second pressure receiving chamber and the exterior of the housing, and a second switch-over part for switching communication/blockage between the second pressure receiving chamber and the escape chamber.SELECTED DRAWING: Figure 1 【課題】双方向への駆動を可能にする水中アクチュエータとそれを備える潜水機を提供する。【解決手段】水中アクチュエータ１Ａは、水中に浸されるハウジング１１と、前記ハウジングの内部に形成されたシリンダ室１２と、前記シリンダ室に摺動可能に収容され、前記シリンダ室を第１受圧室１７と第２受圧室１８に区画するピストン１３と、前記ピストンから前記第１受圧室側に延びて前記ハウジングを貫通するロッド１４と、前記ハウジングの内部に形成され、内部の圧力が前記ハウジングの外部の水圧より低く保たれた逃し室３１と、前記第２受圧室と前記ハウジングの外部との連通および遮断を切り換える第１切換部と、前記第２受圧室と前記逃し室との連通および遮断を切り換える第２切換部とを有する切換機構と、を備える。【選択図】図１
