When the connecting members 11 and 12 are to be separated from each other, the rear connecting member 12 can be forced to swing in the direction shown by the arrow P, so that the opposite side wall 31 of the rear connecting member 12 can cross the first stop. twenty four. At that time, the shaft 32 can be disengaged from the bearing 27. In the buckle 4 constructed as described above, in order to prevent the shaft 32 from unintentionally falling off from the bearing 27, the size of the width L of the opening of the bearing 27 is preferably smaller than the diameter D of the shaft 32, and at the same time the shaft 3 2 is squeezed between the upright wall 16 of the projection 5 and the bearing 27. However, the present invention may be implemented by using only one of these two measures. The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed in the diving fins according to the present invention, each of the buckles for connecting the blade and the heel belt to each other is a simplified structure including only the front connecting member and the rear connecting member, And these two components can be assembled together without time and effort. Under favorable results, diving fins using these buckles can be manufactured at a significantly lower cost than that required to make known diving fins using buckles.
