PURPOSE:To prevent the surface of water from separating from a front end wall by slidably installing a door body having a certain submersible depth on the front end wall of a coast-fixed type air chamber for wave-power power generation, with an oilless lubrication method and maintaining water- and air-tightness. CONSTITUTION:A slidable door body 2 is installed along the front end wall 31 of a coast-fixed type air chamber for wave-power power generation. This door body 2 is formed into a thin box shape the inside of which is made hollow so that its buoyant force is adjusted by means of ballast 4 to enable the door body 2 to float at a certain depth (d). The door body 2 is guided along both side right and left grooves 27 vertically movable between the top and bottom dead centers 14, 26 of a slide to which buffering members, 3, 30 are fixed respectively. Three sets of bearings Ba-Bc are provided in the grooves 27, and the bearing Ba is constructed in such a way that a bush 10a of a sea-water lubricant member installed on a bush housing 9a by means of a rubber packing 11a, can be pressed against a sleeve metal 7a on the door body 2 side. The other bearings Bb, Bc are also nearly equally constructed. |
