The state of being attached to 41 will be maintained.

Referring again to FIGS. 1 and 2, when the helmet wearer wears the goggles 51, the goggle band 52 is attached to the outer periphery of the cap body 1, but the goggle band 52 slips from the cap body 1. In order to prevent it from coming off, a plurality of protrusions 53 that elastically engage with the goggle band 52 are provided at a portion of the edge member 5 corresponding to the goggle band 52, and the protrusions 53 are provided below the goggle band 52. A step portion 54a protruding outward is provided so as to protrude, and step portions 54b protruding outward under the goggle band 52 are provided on both outer surfaces of the shell 2 near the front portion so as to be continuous with the step portion 54a.

The visor body 55 of the visor 6 has a rear face edge closely contacting the outer surface of the shell 2 while having an upper surface 55a that smoothly extends to the outer surface of the cap body 1, that is, the outer surface of the shell 2 and extends obliquely downward toward the front. The visor main body 55 is attached to the cap body 1 with screws 56 in the opened state, and an opening 57 corresponding to the pair of inlets 12 provided in the shell 2 is formed in the central portion of the visor body 55 near the rear. It is provided. Moreover, the peripheral edge of the opening 57 extends toward the outer surface of the shell 2 and abuts against the outer surface.
57a are integrally connected to each other, and the side wall portion 57a is formed so as to surround the pair of introduction ports 12. Thus, the opening / closing lid 58 is pivotable between the position where the opening 57 is opened as shown in FIG. 1 and the position where the opening 57 is closed so that the opening / closing lid 58 is closed.
When the helmet wearer takes a normal riding posture on the motorcycle with the opening / closing lid 58 in the open position, the opening 57 opens forward.

Referring also to FIG. 8, introduction ports on both sides of the opening 57 are also provided.
Three openings 59 are provided in the visor body 55 at a portion corresponding to 13. Moreover, these openings 59 are provided at the front end of each air guide groove 60 provided in the visor body 55 while being deeper from the side surface 55a toward the front and along the front-back direction. When the person takes a normal riding posture in the motorcycle, the opening is made toward the front.

Next, the operation of this embodiment will be described. Interior pad
24 is attached to the cap body 1 in a state in which a bead 28 provided on a peripheral portion thereof is elastically engaged with a locking portion 29 of the edge member 5 at the front part and the rear part of the cap body 1, and Cushions on both sides 35
Attaches the insertion protrusion 36a to the shell 2 and the cushion liner 3.
It is attached to the cap body 1 with the protruding end portion 36b elastically engaged with the locking portion 29 while being inserted therebetween. At this time, the support plate 36 of the side cushion 35 is inserted into the through hole 40 on the side of the interior pad 24, and the portion of the interior pad 24 corresponding to the binaural ears 4, 4 of the cover extension 26 is the side cushion. It will be sandwiched between 35 and the earlid 4. Further, the ceiling pad 31 includes a pair of engaging plates 32 provided on the ceiling pad 31 side, and both ends of the engaging plate 32 provided on the cushion liner 3 side.
It is attached to the cap body 1 by engaging with 33 respectively. Moreover, by engaging the bead 28 of the interior pad 24 and the projecting end 36b of the side cushion 35 with the locking portion 29 of the edge member 5, the lower ends of the shell 2 and the cushion liner 3 are closed over the entire circumference. Thus, mud and the like are prevented from entering between the shell 2 and the buffer liner 3.

Thus, when removing the interior pad 24 from the cap body 1 for washing, for example, with the side cushions 35 removed from the cap body 1, remove the bead 28 from the locking portion 29 of the edge member 5. Further, when the interior pad 24 is attached to the cap body 1, the reverse operation to the above-mentioned removal may be performed. Moreover, the bead 28 provided on the peripheral portion of the interior pad 24 is elastically engaged with the locking portion 29 of the edge member 5, and the engaged state is reliably maintained and the engaging / disengaging operation is performed. It is also easy to perform, and the engaging / disengaging operation is much easier than the conventional one in which the insert piece is inserted between the shell 2 and the cushion liner 3, and the attaching / detaching operation of the interior pad 24 to / from the cap body 1 Can be done easily.

Also, the operation of attaching and detaching the ceiling pad 31 is performed only by engaging and releasing the engaging strings 33 of the two engaging plates 32,
Moreover, even if the ceiling pad 31 gets wet with sweat, the engagement state of the engagement plate 32 with the locking string 33 is not adversely affected, and the cap body 1
It is possible to reliably maintain the attachment state to the.

By the way, the cover plates 19 and 20 are respectively interposed between the inner pad 24 and the front and rear inner surfaces of the cushion liner 3, and the front and rear portions of the inner pad 24 are moved by the head of the helmet wearer. The inner pad 24 will not be pushed into the front end portion and the rear end portion of each ventilation groove 8 and 9 even if it is pressed against the cushion liner 3 side. Further, a pair of engagement plates 32 are attached to the ceiling pad 31, and these engagement plates 32 also prevent the ceiling pad 31 from being pushed into the ventilation grooves 8 and 9. Therefore, when the motorcycle is running, air is introduced into the ventilation grooves 8 and 9 from the ventilation holes 10 and 11, and also from the ventilation grooves 8 and 9.
Air is smoothly discharged to 18 and ventilation grooves 8,
The air flow in the inside 9 becomes smooth, the air flow from the front to the rear is efficiently generated in the ventilation grooves 8 and 9, and the inside of the cap body 1 can be efficiently ventilated.

Moreover, when the helmet wearer takes a normal riding posture on the motorcycle, the opening 57 provided in the visor body 55 of the visor 6 opens forward with the opening / closing lid 58 in the open position. In addition, both openings 59 are also opened forward. Therefore, when the opening / closing lid 14 is in the open position, the openings 57, 59 are not formed when the motorcycle is traveling.
It is possible to reliably introduce fresh air into the ventilation grooves 8 and 9 through the introduction ports 12 and 13. Further, when it is not necessary to introduce a large amount of air into the cap body 1, the opening 57 is provided with the opening / closing lid 58.
If you close the inlet with 13 and open the inlet 13,
A relatively small amount of air can be introduced into the cap body 1 only from the inside, and when the opening / closing lid 14 is closed, the introduction port 13 into the cap body 1 is introduced.
It is possible to block the introduction of air from.

By the way, if the helmet wearer is riding in a motorcycle and his face is facing upward, traveling wind will hit the lower surface side of the visor 6. However, the opening 59 serves to guide the air below the visor body 55 from the air guide groove 60 to the rear side, and therefore even if the helmet wearer faces his or her face upward, the visor 6 is directed rearward by the traveling wind. It is possible to avoid being disturbed as much as possible. In this way, the opening 59 is provided in order to prevent the visor 6 from being tilted.
By bringing the rear edge of the shell into close contact with the outer surface of the shell 2, no step is formed between the visor 6 and the cap body 1, thus improving the aesthetic appearance.

Further, the jaw belt cover 44 is fixed to the jaw belt 41 by engaging a hook-and-loop fastener 48 fixed to the base end portion of the jaw belt 41 and a hook-and-loop fastener 49 provided on the inner surface at one end of the jaw belt cover 44. In order to release the fixed state, pull the jaw belt cover 44 along the insertion direction 47 to release the hook fasteners 48, 49 from the engaged state, and also attach the jaw belt cover 44 to the jaw belt 41. At times, it is sufficient to grasp one end of the jaw belt cover 44 with the jaw belt 41 inserted through the jaw belt cover 44 until one end of the jaw belt cover 44 reaches the base end of the jaw belt 41. The attachment / detachment operation to / from the 41 can be performed extremely easily.

C. Effect of the Invention As described above, according to the present invention, when the chin belt cover is attached to the chin belt, the chin belt is inserted into the chin belt cover to a position where the first and second hook-and-loop fasteners are aligned. Then, it is only necessary to grasp the part of the jaw belt cover corresponding to the hook-and-loop fastener, so that the first and second hook-and-loop fasteners can be engaged with each other and the jaw belt cover can be properly fixed to the jaw belt. On the other hand, when removing the chin belt cover,
When the cheek pad is dirty due to contact with the cheek of the helmet wearer, it can be easily separated from the jaw belt by releasing the hook fastener from the jaw belt by simply pulling on the jaw belt cover. The entire jaw belt cover including the cheek pad can be easily attached to and detached from the jaw belt, and can be easily washed as a single body. Moreover, even though the chin belt cover with the cheek rests can be detached from the chin belt in this way, each chin belt itself can be firmly fixed at its base end to the shell of the cap body from beginning to end. Therefore, there is no possibility that the attachment strength of each jaw belt to the cap body is impaired.

Further, in particular, the first hook-and-loop fastener is fixed only to one surface of the jaw belt, and the second hook-and-loop fastener is fixed to only one inner surface of the jaw belt cover facing the one surface. Therefore, it is possible to reliably prevent the chin belt cover from being set up on the chin belt by turning the chin belt cover upside down. It can always be set correctly in the proper mounting position facing the side.
