<p><P>PROBLEM TO BE SOLVED: To provide a helmet which, when worn by a head of a helmet wearer, can be removed with a comparatively small force, and the detaching operation of which can be performed easily and reliably with a comparatively simple arrangement. <P>SOLUTION: A recess-projection fitting mechanism to attach a blockish inside pad 38b on a head protecting cap portion side includes male hooks 56a-56c or female hooks 92a-92c on the inside pad side 38b, and female hooks 92a-92c or male hooks 56a-56c on the head protecting cap portion. When pulling the inside pad 38b outward from inside the head protecting cap portion at least partly, a recess-projection fitting disengaging slant surface 76b causes one hooks 56a-56c to relatively levitate from the other hooks 92a-92c, thus relatively disengaging the male hooks 56a-56c from the female hooks 92a-92c. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
