  • the right-hand and left-hand chin bands 65 are pulled horizontally (rightwardly and leftwardly, respectively) outwardly, thereby causing the wide portion 52 of the side hemming member 22 to spread, together with the lower parts of the cheek pad 36 and the impact-absorbing member 4, horizontally outwardly in skirt-like form. This helps facilitate the insertion of wearer's head into the helmet through the wearing opening 13, wherefore the wearer is able to put on the helmet 1 with ease.
  • Fig. 10 there is shown the second embodiment in which the impact-absorbing member 4 corresponding to the cheek-covering portion 9 (the cheek-covering body 18) has its lower edge made shorter in the vertical direction so as to be substantially flush with the lower edge 9a of the cheek-covering portion 9 corresponding to the cut-out portion 50, and made concavely above the wide portion 52 of the side hemming member 22 and the lower part of the cheek pad 36, and also, in a region between the wide portion 52 of the side hemming member 22 and the lower part of the cheek pad 36 under the impact-absorbing member 4 corresponding to the cheek-covering portion 9, there is formed a cavity passageway 68 surrounded with the side hemming member 22, the cheek pad 36, and the coupling sheet 63.
  • the lower side of the air passageway 44 communicates with the cavity passageway 68
  • the cheek pad 36 has, in its lower part, a pad communication hole 58 formed therethrough from the inside to the outside so as to communicate with the cavity passageway 68.
  • a single pad communication hole 58 is formed, or a plurality of pad communication holes 58 are spaced apart in the front-back direction, in each of the right-hand and left-hand cheek pads 36.
  • the second embodiment is structurally identical with the first embodiment described earlier. Note that, in the case of this embodiment, the inside-air communication hole 47 of the impact-absorbing member 4 provided in the first embodiment may either be omitted or be provided.
  • the wind flowing laterally outside the helmet shell 3 from front to rear is guided to turn laterally outwardly by the plural outside-air guide surfaces 57, wherefore the air in the helmet shell 3 can be effectively sucked out by the plural air ejection holes 55 arranged in the front-back direction.
  • the exhaled air of the helmet wearer is delivered from the region between the front ends of the right-hand and left-hand cheek pads 36 to the front of the air passageway 44 through the mouth communication hole 46, is whereafter delivered to the rear of the air passageway 44 so as to enter the cavity passageway 68, and is then discharged laterally outwardly of the helmet 1 from the cavity passageway 68 via the plural air ejection holes 55.
  • the inside air within the cheek pad 36 is delivered to the cavity passageway 68 through the pad communication hole 58, so that not only the exhaled air, but also the inside air within the cheek pad 36 can be smoothly delivered out of the air ejection holes 55 through the cavity passageway 68.
  • the helmet 1 is the full-face helmet having the chin-covering portion 10, the helmet 1 is not so limited, but may be an open-face helmet having no chin-covering portion 10.
  • the number of the air ejection holes 55 is not limited to four, but may be one to three, or five or more.
  • the air passageway 44 for causing exhaled air to flow backward for its movement toward the air ejection holes 55 is formed in between the chin-coveringportion 10 as well as the cheek-coveringportion 9 and the impact-absorbing member 4 corresponding to them by creating, at the outer surface of the impact-absorbing member 4 corresponding to the chin-covering portion 10 and the cheek-covering portion 9, the passageway-forming groove in the front-back direction.
  • an air passageway 44 for causing exhaled air to flow backward for its movement toward the air ejection holes 55 within the impact-absorbing member 4 located inside the chin-covering portion 10 and the cheek-covering portion 9 by creating, in the impact-absorbing member 4 corresponding to the chin-covering portion 10 and the cheek-covering portion 9, a passageway-forming groove in the front-back direction.
  • an air passageway 44 for causing exhaled air to flow backward for its movement toward the air ejection holes 55 can be formed in between the cheek pad 36 and the impact-absorbing member 4 located inside the chin-covering portion 10 and the cheek-covering portion 9 by creating, at the outer surface of the impact-absorbing member 4 corresponding to the chin-covering portion 10 and the cheek-covering portion 9, a horizontally-inwardly sunken passageway-forming groove in the front-back direction.
  • the impact-absorbing member 4 situated ahead of the mouth of the helmet wearer is formed with the paired right-hand and left-hand mouth communication holes 46, instead of this, it is also possible to form a single mouth communication hole 46 in the impact-absorbing member 4 situated ahead of the mouth of the helmet wearer so as to communicate with the fronts of the right-hand and left-hand air passageways 44.
