[0002]

2. Description of the Related Art When mounted on a motorcycle, a helmet is required to be worn. In general, a conventional helmet is provided with a helmet as an impact cushioning material to protect the head when worn. A foamed resin material is disposed between an outer shell material and an inner shell material of the cap shell. Since the liner as the shock absorbing material is inexpensive, lightweight and has good performance, styrene foam is generally used.

[0003] Styrofoam or the like used as the above-mentioned shock buffering material (so-called liner) has excellent heat insulating properties in addition to buffering shocks, so that it has a cold protection effect when worn in winter and in summer. Has the advantage that heat transfer from the outer shell material heated by direct sunlight or the like can be effectively blocked.

[0004] However, because of the heat insulating effect as described above,
When used in summer, the helmet internal temperature will be 45
Since the temperature rises to more than ℃, there is a problem that the helmet wearer is uncomfortable due to abnormal sweating, odor and the like due to the temperature rise.

[0005]

For this reason, recent helmets equipped with a ventilation system have been put on the market. In this ventilation system, an air inlet for introducing air into the front of the helmet and an air outlet on the rear of discharging the air are formed, and the wind (air) flowing into the helmet from the air inlet during traveling is controlled. After flowing through the air outlet, it is discharged from the air outlet.

A helmet equipped with the above-mentioned ventilation is suitable for use in the summer, but on the other hand, in the winter, even if the air inlet is closed, the helmet has a disadvantage that it is cold because of the good air flow. For this reason, helmets provided with ventilation are generally inconvenient for use in winter and tend to be used only in summer. Helmets with such a limited period of time cannot be used throughout the year, and during that time they lose their product value.

In a helmet in which a foamed resin material such as styrene foam is disposed between an inner shell material and an outer shell material, these inner shell material, outer shell material, foamed resin material, interior Parts for processing and attaching / detaching the material are required, and the number of processed parts and the number of parts are increased.

It is an object of the present invention to provide a helmet provided with a ventilator which can be used comfortably all season.

Another object of the present invention is to provide a helmet provided with a ventilator which can easily change the application conditions in hot or cold weather.

It is a further object of the present invention to provide a helmet provided with a ventilator which can easily attach and detach an interior material with little processing and without increasing the number of parts.
