Abstract
A helmet that can be removed from the head of a helmet wearer who wears the helmet, with a comparatively small force, and simply and quickly including preliminary operation for removal. A recess-projection fitting mechanism to attach a blockish inside pad to a head protecting cap portion includes a male hook on a blockish inside pad side, and a female hook on a head protecting cap portion side. The interrupt portion of a pad takeout member including a pulling means can interrupt between the male hook and female hook to disengage their recess-projection fitting, and can catch on the male hook, and the male hook can be pulled out to outside the head protecting cap portion at least halfway.
