ABSTRACT:
A helmet has a chin cover portion formed immediately below a window opening of a front of a cap body. A recess is formed on a front surface of a shell at the chin cover portion. A housing covers the recess and opens at an upper end to the window opening. The housing is secured to the shell. Air intake holes are formed at the housing. A distribution chamber and a plurality of air introducing ducts are defined between the housing and a bottom of the recess. The ducts upwardly extend from the distribution chamber and communicate with a plurality of jet holes. The distribution chamber of a large volume can be formed without impairing the strength of a buffer liner inside the shell. The air introduced from the air intake holes can be reliably jetted out to the inner surface of the shield plate which closes the window opening, to prevent a cloud forming on the inner surface of the shield plate.
