  Therefore, when the bundle of hairs H is sandwiched between the upper hair clamping surface 4A and the lower hair clamping surface 4B, the sandwiched hair H is interposed between the upper hair clamping surface 4A and the lower hair clamping surface 4B. When the hair iron 10 is warmed and pulled down toward the end of the hair while sliding along the hair H, the hair H can be straightened.

  Here, in the present embodiment, when the upper and lower hair clamping surfaces 4A and 4B are brought into contact with each other in a state where the hair H is not sandwiched, a space portion is formed between the upper hair clamping surface 4A and the lower hair clamping surface 4B. 6 is formed.

It is preferable to design so as to be about a millimeter. Since the diameter of the general hair H is 0.05 mm or more, if the size of the space portion 6 is less than 0.05 mm, the pressing force for sandwiching the hair H is increased, and the size of the space portion 6 is increased. This is because if the amount is too large, an effective pressing force cannot be applied, and the hair H cannot be straightened.

  Furthermore, in the present embodiment, at least the lower hair clamping surface (second hair clamping surface) 4B of the upper and lower hair clamping surfaces 4A, 4B is supported so as to be movable relative to the case (clamping body). ing.

On the other hand, since the lower hair clamping surface 4B moves relative to the amount of the hair H to be sandwiched, it is possible to effectively perform straight squeezing while minimizing damage to the hair H.

  In the present embodiment, the four corners of the hair clamping member 16 are supported by the float springs 12, but the position and number of the float springs 12 can be set as appropriate. Moreover, it is preferable that the movable range of the hair clamping member 16 in the vertical direction is set to be about 0 to 3 mm. If the movement amount is 3 mm or more, the load applied to the sandwiched hair H and the frictional force generated when the hair is pulled down increase, and it becomes difficult to smoothly slide the hair iron 10 along the hair H. is there.

  Further, as shown in FIG. 1, a plurality of upper side clamping parts (first clamping parts) 2 </ b> A are provided at both ends in the width direction along the longitudinal direction of the clamping part 2, so as to follow the width direction of the clamping part 2. Guide protrusions 24 for guiding the hair H are provided.
