    • A small watercraft equipped with a lock mechanism for an engine hood is disclosed. The watercraft includes a deck, an engine hood that is pivotably provided to the deck around a pivot shaft, and covers an engine room thereunder from above so as to open and close, and a lock mechanism for locking the hood in an open position. The mechanism includes one member attached to the hood, another member attached to the deck, and a stopping member. At least one of the one member and the another member is formed with a protruding portion that protrudes in the radial direction of the pivoting. The stopping member is attached to the other member, and the protruding portion engages with the stopping member when the engine hood reaches a predetermined open position so that the protruding portion stops the pivoting of the one member to lock the hood in the position.
    • 公开了一种装有发动机罩的锁定机构的小型船只。 船舶包括甲板,发动机罩,其枢转地设置在甲板周围的枢轴上,并且从上方覆盖其下方的发动机室以便打开和关闭;以及锁定机构,用于将发动机罩锁定在打开位置。 该机构包括附接到罩的一个构件,附接到甲板的另一构件和止动构件。 一个构件和另一个构件中的至少一个形成有在枢转的径向方向上突出的突出部分。 止动构件附接到另一构件,并且当发动机罩达到预定打开位置时,突出部分与止动构件接合,使得突出部分停止一个构件的枢转以将发动机罩锁定在该位置。

    • A bulkhead structure for a personal watercraft reduces the weight of the personal watercraft while maintaining the rigidity of an outer shell of a body by utilizing the inside space of the body. Alternatively, the structure can further enhance the rigidity of the outer shell of the body without increasing the weight. The hull and a deck are joined to form the outer shell of the body of the personal watercraft. A plate-shaped member spans substantially horizontally in a direction of the width of the body of the personal watercraft and has right and left sides fixed in the vicinity of a junction portion of the hull and the deck.
    • 用于个人船只的舱壁结构通过利用身体的内部空间来保持个人船舶的重量,同时保持身体外壳的刚性。 或者,该结构可以进一步增强身体的外壳的刚性,而不增加重量。 船体和甲板连接形成个人船体的外壳。 板状构件在个人船舶的主体的宽度方向上基本上水平地延伸,并且具有固定在船体和甲板的接合部分附近的左右两侧。
