To provide a rudder plate provided with a rudder plate hub with reduced total weight, capable of being manufactured with suppressed amount of material and cost, and insuring sufficient high strength in comparison with a conventional rudder plate.SOLUTION: A facility is proposed for a water craft, especially for a case of a ship with a semi-balanced rudder or a full spade rudder including: a front edge and a back edge, a first side wall (12), a second side wall (13) positioned on a side facing the first side wall (12), and a rudder plate hub (17) arranged in a connection space (16) for connecting a rudder stock, in the case of the rudder plate provided with the rudder plate hub. The rudder plate hub (17) includes a hub body (29). The hub body (29) includes an inner bore (30) for receiving the rudder stock for a hub outside surface (31) which should be arranged to be totally separated from an inner side surface of the first side wall (12) and an inner side surface of the second side wall (13), and the hub outside surface (31) extending in the periphery direction.SELECTED DRAWING: Figure 4

    【課題】従来の舵板と比較して、全重量が低減し、材料およびコストをおさえた製造が可能で、十分な高強度を保障している、舵板ハブを備えた舵板を提供する。【解決手段】舵板ハブを備えた舵板の場合、前縁と後縁と、第1の側壁(12)と第1の側壁(12)の向かい側に位置する第2の側壁(13)と、ラダーストックを連結するための連結空間(16)に配置される舵板ハブ(17)と、を含む、ウォータ・クラフト、特に船のための半釣合舵またはフルスペード舵の場合において設備を提案する。舵板ハブ(17)はハブボディ(29)を含み、ハブボディ(29)は、その全体が第1の側壁(12)の内側側面と第2の側壁(13)の内側側面とから離隔されて配置されるべきハブ外側表面(31)のために、ラダーストックを受容する内側ボア(30)と、周方向に延びたハブ外側表面(31)を含んでいる。【選択図】図4
