Abstract
The surfboard fin, in particular, a long surfboard fin has been fixed to or removed from the surfboard under application of a washer and a screw. This operation is quite inconvenient and the fin is removed or fixed when the surfboard is used or is not used, resulting in that the prior art fin has required a quite amount of labor for it. The present invention enables this operation to be carried out manually in an easy manner. The box is fixed to a groove formed at the surfboard with adhesive agent and then the inside part of the box is formed with two grooves standing at different levels. The front long groove is positioned at a slight higher location and one pin of the fin can be inserted into the groove. The rear part pin can be inserted into several L-shaped grooves arranged at a slight lower part of the rear part of the box. The fin has a slight higher front part, has a step and the rear part is positioned at a slight lower location and the front part and the rear part have a total number of two pins each of which is set at the front part and the rear part, respectively. With such an arrangement as above, the fin can be fixed by fitting the two pins into both grooves and the troublesome fixing or removing operation of the fin can be overcome.
