Has been done. A hole 2 that opens is formed on the one side surface 6 to which the bristle substrate 6 is fixed and the other side surface 10 on the back side, and the hole 2 is provided with a hole opening / closing means 3 for opening and closing the hole 2. Has been done.

The hole opening / closing means 3 is composed of a lid part for closing the hole 2 and an opening / closing part 4 made of a shape memory alloy for opening the hole 2, and the opening / closing part 4 is a hole above the transformation point. 2 is opened, and the transformation point is set so as to return to the memorized shape below the transformation point. The opening / closing means 4 made of a shape memory alloy may have a plate shape or a rod shape.

The bristle substrate 6 is formed of a flexible material such as rubber or soft synthetic resin. The bristle holes are formed at the same pitch as the bristle 5, and the small holes 61 are formed between the rows of the bristle holes. They are lined up.

The bristle 5 may be formed into a unit by connecting the base portions of the bristle 5 with a connecting piece. The bristle 5 is passed through the bristle holes formed in the bristle substrate 6 from the back side, and the bristle substrate is also formed. It is fixed to the bristle substrate 6 by being heat-welded on the back side of 6. Also, the bristles 5 and the bristles substrate 6 may be fixed by two-color molding in a molding die.

As shown in FIG. 5, a large amount of hair is wrapped around (not shown), the inside of the brush 1 overheats to an abnormal temperature, and when the temperature exceeds the set temperature, the opening / closing part 4 of the hole opening / closing means 3 opens the lid part. The holes 2 are moved to open the holes 2, and the hot air is released. Then, the fixed end of the hole opening / closing means 3 is located at the tip end side, and the movable side of the lid part of the hole opening / closing means 3 is formed to face in the air blowing upper hand side direction. The lid serves as a guide plate and allows the abnormal warm air to escape. When the temperature drops, the hole opening / closing means 3 made of a shape memory alloy returns to its original state, and the lid block the hole 2 to prevent the temperature from dropping more than necessary. Since the hole opening / closing means 3 can automatically operate by raising or lowering the temperature, the temperature inside the brush 1 can be kept substantially the same, and the convenience of use can be maintained without worrying about the hair winding amount and the use time. It will improve.

Then, as shown in FIG. 6, the curling performance of the hair can be further improved by hitting the wound hair with the warm air escaping from the hole 2 on the back surface.
