Description of the Related Art In a conventional rowing boat that rows an oar with an oar catch on the side of a ship as a fulcrum, the maximum force can be exerted when the grip portion of the oar is pulled toward the front, so that the axle where the rower is in the traveling direction is used. The boat rowing with the back was all. The downside of this rowing boat is that you have to look back often during the rowing to make sure
Every time I was out of hand, and I couldn't run in a stable way.
Rowers are mentally comfortable if they can look forward and can avoid unexpected waves and obstacles, but it was difficult with conventional rowing boats.

した手漕ぎボートについてを課題とする。SUMMARY OF THE INVENTION In order to solve the drawbacks of the present invention, the rower can row the ball in the advancing direction while the rower can exert the maximum force as before. It is an object to provide a boat oar and a rowing boat to which the oar is fixedly mounted.

When you pull, the webbing must be made to scratch the water. Therefore, the grip part of the oar and the webbed part are divided by the part of the body that is in the middle, and a fixed gear is provided in each of the divided parts, and a `` mechanism part that changes the direction of the force '' is provided. The problem was solved by attaching the part to the all receiver on the side of the boat.

部が水を掻くことになる。Various examples of the "method of changing the direction of force" for obtaining the above-mentioned effects are conceivable, but the following examples will be given as typical ones. (A) As shown in FIG. 1 and FIG.
A steel tube is welded to each of the gears on the opposite side of the meshing side. One of the cylinders is used as a grip portion, and a web made of resin or the like is attached to one side. (B) The present invention can also be implemented by cutting an already-made oar into the tube manufactured by shortening the above-mentioned tube at the body, and inserting and fixing each of them. (C) As shown in FIGS. 3 and 4, a square opening is provided in the trunk A of the oar that moves about the fulcrum A. A bearing that contacts the inside of the rectangular opening is provided on the barrel B of the oar that moves about the fulcrum B. Now, if the grip portion of the oar is pulled to the left in the drawing, the rectangular opening rotates rightward about the fulcrum A. At this time, the rectangular opening pushes the bearing fixed to the barrel B of the oar to the right in the drawing. The torso B of the oar rotates the webbed part to the left around the fulcrum B, so the grip part and the webbed part of the oar move to the same left direction, and the hiragana "ku"
Draw a letter. Therefore, when the grip portion of the oar is pulled, the webbing portion scrapes the water.

可能になる。[Effects of the Invention] Just as the back driving of a car is difficult in terms of maneuverability and safety, there is a danger such as a grounding and collision in a conventional rowing boat. If the oar according to the present invention is mounted, since the rowing can be faced directly in the traveling direction, the above-mentioned inconvenience can be eliminated, and a rowing boat with a sufficient margin and a fun boating can be enjoyed.
