To provide an adjustable jet device attachable to a surf board.SOLUTION: An adjustable jet device attached to a surf board has a structure: including two horizontally symmetrical push plates 11 and two horizontally symmetrical holding blocks 46; installed each in between the push plate and the holding block, with fixing mechanisms 101 each capable of strongly sandwiching the push plate and the holding block, so as to fix them on right and left sides of the slide plate 13; comprising an extending mechanism 102, etc., capable of having a length extending horizontally adjusted to adapt to a width of the slide plate in between the two right and left holding blocks; and capable of being attached to a surf board and having the surf board proceed while accelerating it by a jet method on a water surface without waves as well as stopping ejection of air when changing direction, thus working to decelerate, improving possibility for adjustment, and capable of being combined with different types of surf boards.SELECTED DRAWING: Figure 1
【課題】サーフボードに取り付けられる調節可能なジェット装置を提供する。【解決手段】左右対称になる二つの押し板11と左右対称になる二つの挟みブロック46を含み、前記押し板と前記挟みブロックとの間には前記押し板と前記挟みブロックをきつく挟んでスライド板13の左右両側に固定できる固定機構101が設置され、左右二つの前記挟みブロックの間には前記スライド板の幅に対応できるように左右に延伸する長さが調節可能な延伸機構102等から構成され、サーフボードに取り付けられ、波のない水面でジェット式によりサーフボードを加速度で進ませる上に、方向を変える時に空気を噴くことを止められ、こうして減速の効果を果たせ、調節可能性を向上させ、異なるタイプのサーフボードと組み合せられる構造を有する。【選択図】図1
