Although an accelerator interlocking member (26) and an acceleration
function follow-up member (28) magnetically coupled with each other when
an automobile stops or travels at a car speed less than a predetermined speed are
released from the magnetic coupling when an accelerator erroneous operation is
made, a normal operation security apparatus (100) serves to lock the accelerator
interlocking member and the acceleration function follow-up member so that they
are mechanically coupled whereby the accelerator interlocking member and the acceleration
function follow-up member are integrally coupled with each other to prevent the
release of the magnetic coupling of them on a normal operation so as to be enable
to positively perform the overtaking operation and the ascent hill travel.
