However, since the top surface of this type of bicycle has a single-layer structure, it cannot be said that the shape retention force against external pressure is sufficient, and therefore, for example, the rider's exercise load is locally applied to the foot rest area while riding. If it hangs, there is a risk that the same part will cave in and make the running balance unstable.
In addition, since this structure does not have a side-sway prevention mechanism such as a front fin on the underside, there is a risk of inadvertent side-slip phenomenon while moving, which may cause instability while driving. There was a problem.

The embodiment shown in the figure is a surfboard body in which the entire periphery of a top sheet 1 made of thermoplastic soft synthetic resin, an intermediate sheet 2 made of the same, and a bottom sheet 3 made of the same are high-frequency welded to each other to form a bamboo leaf shape. 4, and extends between the intermediate sheet 2 and the lower sheet 3 along a line connecting the tip and tail of the surfboard body 4, and has both ends close to the edge of the tip and the edge of the tail. By sandwiching a large number of hanging pieces 5 and high-frequency welding the upper and lower ends of these band-shaped hanging pieces 5 to the intermediate sheet 2 and the lower sheet 3, when the surfboard body 4 expands, both ends are attached to the edge of the tip and Convex lines 6, 6' and concave lines 7 reaching the edge of the tail end,
7' are formed on the upper surface of the intermediate sheet 2 and the lower surface of the lower sheet 3, and a supply/exhaust plug 8 is provided on the wall of the surfboard body 4 for supplying and exhausting air between the intermediate sheet 2 and the lower sheet 3. In addition, fins 9 made of slightly hard thermoplastic soft synthetic resin are attached to the rear half of the lower surface of the lower sheet 3 at the locations where the convex stripes 6' are formed, and furthermore, fins 9 made of a slightly hard thermoplastic soft synthetic resin are attached to the intermediate portion of the lower surface of the lower sheet 3. A long narrow piece 10 made of thermoplastic soft synthetic resin is brought into contact along the convex line 6' at the location where the convex line 6' is to be formed, and both side edges and one end edge of the narrow piece 10 are high-frequency melted to the lower sheet 3. A reinforcing rod-shaped body 12 is inserted into and removed from the bag 11, and a slightly hardened reinforcing rod-shaped body 12 is inserted into and removed from the bag 11. A reinforcing sheet 13 made of soft thermoplastic synthetic resin is placed, and the entire periphery of the reinforcing sheet 13 is high-frequency welded to the top sheet 1, and a slightly hard thermoplastic soft material is placed on both sides of the middle part of the top sheet 1. Synthetic resin handle 1
4, 14' are attached, a belt 16 with a length adjustment fitting 15 is connected to one handle 14, the tip 17 of this belt 16 is passed through the other handle 14', and the tip 17 is folded in half. Hook-and-loop fasteners 18, 18' that engage with both of the bifold parts

As described above, the surfboard body is constructed by welding the entire circumferential edges of the top sheet, middle sheet, and bottom sheet made of thermoplastic soft synthetic resin to each other, and the surfboard body is constructed between the middle sheet and the bottom sheet. A large number of band-shaped hanging pieces are inserted along a line connecting the tip and tail ends of the band-shaped hanging pieces, each end of which is close to the edge of the tip end and the edge of the tail end, and both upper and lower ends of these band-shaped hanging pieces are inserted. is welded to the middle sheet and the bottom sheet, and an exhaust plug 8 is attached to the wall of the surfboard body between the middle sheet and the bottom sheet, so the upper part of the board has a double structure of the top sheet and the middle sheet. Therefore, the shape retention force against external pressure is also high, so even if the rider's exercise load is locally applied to the footrest part during running, this part will become depressed, causing defects such as unstable running balance. In addition, in the present invention, forward-facing fins are formed at the bottom of the lower sheet, so there is no chance of accidental skidding while the vehicle is moving.Furthermore, the fins are provided at a location near the rear of the lower sheet, which prevents this from occurring. The surfboard of this invention does not restrict the overall direction of the board more than necessary and prevent the rider from intentionally twisting his/her waist or changing the balance of motion, etc. This has the effect of making extremely stable windsurfing possible.
