To provide a water surface propulsion device which is light weight, easy to carry, and with high operability.SOLUTION: A water surface propulsion device to be attached to a floating body is composed with: a slider composed to be attached to the floating body; a driving shaft of a pillar body composed to penetrate inside the slider in the vertical direction to a bottom surface of the floating body; a pedal connected to a top end unit pf the driving shaft; a connection unit connected to a bottom end unit of the driving shaft; a fin connected through a revolving shaft of the connection unit; the fin composed to be capable of rotation with a shaft of the connection unit as a center; and a stopper provided restricting the rotational angle of the fin in the upward direction to be relatively smaller than the rotational angle in the downward direction.SELECTED DRAWING: Figure 1

    【課題】軽量で持ち運び容易であり、操作性の高い水上推進装置を提供する。【解決手段】浮体に取り付けるための水上推進装置は、浮体に取り付けられるように構成されたスライダと、浮体の底面に対して垂直方向にスライダ内部を貫通するように構成された柱体の駆動軸と駆動軸の上端部に接続されたペダルと駆動軸の下端部に接続された接続部と、接続部の回動軸を介して接続されるヒレで構成され、ヒレは接続部の軸を中心に回転可能に構成され、更にヒレの上方向への回転角度が、下方向への回転角度よりも相対的に小さくなるように制限するストッパーを備えた水上推進装置を提供する。【選択図】図1
