PROBLEM TO BE SOLVED: To provide a helmet having sufficient impact absorption capacity while obtaining high air permeability and heat radiation.SOLUTION: Four leg parts of a hammock 2 extending downward from a crown part include a pair of front leg parts 6a and 6b and a pair of rear leg parts 7a and 7b. The pair of front leg parts 6a and 6b are formed in an entire arch shape extending circularly from the crown part side to connection parts 8, and the pair of rear leg parts 7a and 7b are formed in the entire arch shape extending circularly from the crown part side to the connection parts 8. Thus, the shapes of the front and rear arch shapes can sufficiently absorb an impact force received from directions other than the crown part side during overturn and fall of a wearer.SELECTED DRAWING: Figure 1 |
