Another conventional hair curler is disclosed in Japanese Utility Model Laid-Open Publication No. 56-52886. FIG. 20 shows a conventional example in which a synthetic resin bobbin constituting a hair winding body 2 formed to have elasticity in a radial direction is provided with a flexible heater capable of being deformed together with the bobbin. It has a built-in structure.

In the above-mentioned conventional example, in the hair curler shown in FIG. 16, when the hair is wound around the hair winding body 2 having a C-shaped cross section, tension is applied to the hair to secure the curl as shown in FIG. However, there is a problem in that one of the ends of the hair winding body 2 having a C-shaped cross section is rolled up to form a step, and the hair is curled with the step.

In the conventional example shown in FIG. 18, the hair winding body 2 is flexed and temporarily fixed by a hair pin 25, and the hair is wound. Then, the hair pin 25 is pulled out, so that the hair is tensioned and curled. Is attached,
There is a problem that it takes time to remove the hairpin 25 after temporarily fixing the hairpin 25 and winding the hair. In addition, when the hair is wound, the hair is temporarily fixed with the hairpin 25, so that the hair winding body 2 is in a rigid state as in the case of a tubular hair curler, so that tension is hardly applied when winding the hair, and the hair is aligned and wound neatly. There is a problem that it is difficult. In addition, there is a problem that a gap is generated after the hairpin 25 is pulled out, the hair is stepped at the corner of the gap between the locking pieces 22 at that time, and it is difficult to form a beautiful curl. Further, in this conventional example, since the hair curler itself does not have a heating means, there is a problem that it is necessary to externally heat or leave the hair curler for a long time to firmly curl.

Further, in the conventional example shown in FIG. 19, when the hair is wound around the hair winding body 2 in order to firmly curl the hair, since the cylindrical hair winding body 2 is a rigid body, tension is applied when the hair is wound. There is a problem that the hair is hard to be applied, and it is difficult to arrange the hair and to wind it neatly.

In the conventional example shown in FIG.
The energizing terminals are arranged at opposite positions on the circumference of the cylindrical connecting member, so if various hair curlers with different diameters are created to perform various curling, the distance between the energizing terminals changes Therefore, there is a problem that a power supply device for supplying electricity to the current-carrying terminals is required by the number thereof. Further, in this conventional example, the bobbin made of synthetic resin constituting the hair winding body 2 has elasticity in the radial direction and can be deformed. However, since the bobbin is cylindrical, it can be deformed around the circumference of the hair winding body 2 itself. The lengths are the same. Therefore, even in this conventional example, there is a problem that it is difficult to apply tension when the hair is wound around the hair winding body 2 in order to firmly curl the hair, and it is difficult to clean the hair by aligning the hair.
