<p>A helmet, wherein a stabilizer part having an air flow deflection surface (63) apart gradually from the outer peripheral surface of a head protective body ranging from a front end to a rear end, a stabilizer component member having a vent port forming part (61), or a vent port forming member (51) is disposed on the outside of the head protective body, exhaust ports (55a to 55c) are provided in a step surface (64) substantially extending from near the rear end of the air flow deflection surface (63) to the outer peripheral surface of the head protective body, and the vent port forming member (51) further comprises air flow dividing parts (62a, 62b) having exhaust ports (54a, 54b) substantially surrounded by fork projected parts (66) to effectively exhaust the air inside the head protective body through the exhaust ports (55a to 55c) and/or (54a, 54b), and the specified traveling stability of the head protective body can be achieved.</p> |
