Further, in order to manufacture the head pad 5, the sponge material 5a and the cloth 5b are cut separately in advance, and then both are overlapped, adhered, and sewn. Therefore, the number of component parts and manufacturing steps increase. Moreover, since the head pad 5 is made up of a plurality of parts and a large number of processes, the dimensional accuracy tends to vary. Therefore, the yield of the head pad 5 is low. Furthermore, since the interior material is composed of a plurality of independent members, it is difficult to position the interior material when it is fitted into the liner, and because it is a soft material, it is easily deformed, making it difficult to handle during the manufacturing process.

All of these are known. Note that a plurality of ventilation grooves 13 are formed on the inner surface of the liner 11 in the front-rear direction. The interior material 12 is formed into a shape that can be fitted into the liner 11 by integrating a head part 14 that contacts the top of the head and a head side pad part 15 that surrounds the side part of the head. In order to prevent the head from getting stuffy, a ventilation groove 16 is formed on the inner surface of the head part 14 in a substantially ring shape to surround the top of the head, and correspondingly, a large number of ring-shaped protrusions 17 are formed on the outer surface. ing. The presence of the annular protrusion 17 on the outer surface prevents the hexion portion 14 from coming into close contact with the inner surface of the liner 11, improves the air permeability between the liner 11 and the interior material 12, and improves air cooling of the hexion portion 14 and the head pad portion 15. Stay effective.
Furthermore, a plurality of ventilation grooves 18 extending in the vertical direction are formed at appropriate intervals on the inner surface of the head pad portion 15. This ventilation groove 18 communicates the top of the head with the outside air through the lower end of the helmet, thereby maintaining ventilation inside. Note that the ventilation groove 18 is provided not only in the side part of the head as in this embodiment, but also in the head part 1.
4 may be formed on the entire inner surface of the interior material 12. Further, the lower end portion of the head side pad portion 15 is folded back outward to have a substantially J-shaped cross section to form a bent portion 19. The tip portion 19a is fitted within a gap 21 formed between a step portion 20 formed on the outer periphery of the opening of the liner 11 and the inner circumferential surface of the opening of the shell 10 (see FIG. 4).
