The connecting member 2 has a hole 3 for fixing through the cord 1, but has an internal space 11 following the hole 3, into which the tip portion 6 of the strap portion 5 is inserted and fixed with an adhesive. Things. Accordingly, the coupling structure of the hand strap structure of the present invention is generally a coupling member 2 having a certain degree of rigidity and a flexible strap portion 5 coupled with an adhesive.

The strap portion 5 must be adapted to fit in the hand so as to be gripped by hand. Therefore,
Care must be taken in choosing the plastic resin used for molding. Since the strap portion 5 is joined to the joining member 2 with an adhesive, the strap portion 5 is formed of a soft resin,
Even if the coupling member 2 is generally made of a hard resin, the two-color molding technique is not required.

[0016]

Embodiment 2 FIG. 2 is different from FIG. 1 in that a hole 13 having a screw-shaped inner wall is provided in the two ends of the strap portion 5,
On the other hand, the coupling member 2 has two protrusions 12 each having a barb shape as shown in an enlarged view on the strap portion 5 side, and each protrusion 12 is provided at each loop end 6 of the strap portion 5 with a screw hole. When the insertion member 13 is inserted and fixed, the joining member 2 and the strap portion 5 are firmly joined. Furthermore, you may glue using an adhesive.

The strap portion 5 has a shape that can be grasped by hand, and therefore, a long belt-shaped or long object having a circular cross section is suitable. Mounting string 1
Is a portion for fixing to a portable device, and can be changed in shape as such, and can be formed into a convenient shape for fixing as such.
