In a helmet (H) including a chin-covering portion provided on a cap body (1) to define a space (3) for breathing of a user, the chin-covering portion (1a) includes a lower end edge (10) which is formed to be directed upwards in a backward direction on wearing position of the cap body (1), and bulges (12) formed at left and right outer surfaces thereof to be continuous to the lower end edge (10). Therefore, travel wind (W) is passed on outer surfaces of the bulges (12) to traverse the lower end edge (10), thereby generating a negative pressure or vacuum at a lower portion of the chin-covering portion (1a) to draw out the user's breath in the breathing space (3) to below the chin-covering portion (1a). Thus, the fogging of an inner surface of a shield plate (6) is prevented without deteriorating the strength of the chin-covering portion (1a). <IMAGE> |
