Abstract:
Provided is a helmet that can effectively reduce the rotational speed of an impact and at the same time can effectively reduce translational acceleration. The helmet is provided with outside headgear formed from a hard material and an impact absorbing liner (14) disposed inside this headgear. The impact absorbing liner (14) is provided with a main body liner (16), a concave part (30) provided on the inside surface of this main body liner (16), an insert liner (18) mated to this concave part (30), and a central convex part (42) (central support member) disposed between bottom surface of the concave part (30) and the bottom surface of the insert liner (18).
