2. Description of the Related Art Conventionally, there are two types of helmets that are mounted on a motorcycle, such as a jet type and a full face type. Jet type helmets are made so that only the head is covered with a cap shell and the face is exposed to the outside, while the full face type helmet is configured to cover not only the head but also the entire face. It was done. Jet-type helmets are light and easy to wear. On the other hand, a full-face type helmet has high safety,
Wearing is troublesome.

[0003]

[Problems to be Solved by the Invention] A motorcycle usually has four
Since the vehicle travels on the same road as the wheeled vehicle, the driver is easily affected by the exhaust gas from the four-wheeled vehicle while the vehicle is running. When actually riding on a two-wheeled vehicle, the driver often runs just behind the exhaust duct of a four-wheeled vehicle, and has to run while directly inhaling the exhaust gas. This is the driver of a four-wheeled vehicle that can run with the window glass tightened,
It will inhale the exhaust gas so rich that it is unmatched by a passerby walking on a sidewalk a little away from the roadway.

The harmfulness of exhaust gas is clearly stated by an allergy specialist, and there is data that almost 100% of children living near intersections where traffic is heavy become asthmatic. It is also said that long-term inhalation of rich exhaust gas increases the risk of lung cancer.

As described above, when riding on a motorcycle, the vehicle directly inhales exhaust gas, so it can be said that the driver is at risk of suffering from asthma and lung cancer. In order to protect themselves from such dangers, drivers have conventionally devised ways to reduce the effects of exhaust gas, such as wearing a helmet and running while wearing a sanitary mask. Is the reality. However, it is hard to wear a helmet over the mask, and it does not look good. Further, there is a drawback that the mask cannot be removed with the helmet on, and that a hygiene mask or a hay fever mask that is usually on the market is easily affected by wind during traveling.

On the other hand, a full-face type helmet provided with a filter on the chin covering portion is disclosed in Japanese Utility Model Laid-Open No. 59-426.
No. 6,086,045. The helmet disclosed in this publication is developed for motocross competition, and has a filter attached to prevent mud and sand while traveling on a rough road. A full-face type helmet provided with such a filter has a problem that it is difficult to attach and detach the helmet as described above. In particular, jet-type helmets are widely used for driving on ordinary roads because of their simplicity and other reasons.In a clean place where there are few cars around, you may want to take off your face to drive. . Further, in recent years, some banks, convenience stores, and the like prohibit access to the store with a full-face type helmet on, and it is very inconvenient to take off the entire helmet each time.

In the construction of the helmet disclosed in Japanese Utility Model Laid-Open No. 59-426, since the entire face is covered with the helmet, the driver's exhalation stays inside the helmet and the front of the eyes is covered. There is also a problem that it is difficult to see ahead. In most actual helmets, a transparent wind shield called a shield is provided in front of the cap shell 1, but it is omitted in the drawings of the present invention.

According to the helmet of the present invention, since only the mask portion including the filter can be easily removed from the cap shell of the helmet, the helmet has the filter function while maintaining the easy attachment / detachment characteristic of the jet-type helmet. A helmet can be provided. Therefore, when traveling in a state where there are few cars around and the vehicle is not affected by exhaust gas and the like, it is possible to take off the mask part and enjoy traveling freshly. Further, since the air filter itself is also removable from the mask portion, the filter can be easily replaced. In addition, it is preferable to use an air filter having as fine a mesh as possible, and it is more preferable if it has a deodorizing effect.

Further, a preferred embodiment of the present invention is characterized in that an exhaust valve is provided below the air filter of the mask portion. That is, it is necessary to use a filter with fine eyes in order to improve the performance of the filter, but if a filter with fine eyes is used, it will take force to breathe. Therefore, an exhaust valve is provided so that at least exhalation can be performed easily.
