said frame is mounted on the head;
a front compressing portion provided on said frame or said apparatus body, and compressed against a frontal region of the
head;
first and second adjusters provided at both sides of said frame so that said first and second adjusters can move in the longitudinal
direction relative to said frame;
a back member that includes a back compressing portion compressed against an occipital region of the head, and is held by
said first and second adjusters; and
an interlock mechanism for enabling, as one of said first and second adjusters moves relative to said frame, the other of
said first and second adjusters to move with the same moving amount relative to said frame in the same direction as the one;
wherein each of said first and second adjusters includes a lock mechanism for locking and unlocking a unidirectional movement
of said adjuster in the longitudinal direction relative to said frame, and
