PROBLEM TO BE SOLVED: To prevent forward movement of a heel part at the time of a collision without damaging the degree of freedom of foot movement at an ordinary time by projecting a stopper member receiving the heel part on a floor surface at only the time of a collision. SOLUTION: A recess 6 is provided at a horizontal direction location which matches with a pedal 5 of the lower part of a toeboard 3. The recess 6 stores an air bag 7 incorporating a gas generator 7a and the opening part is covered with a cover 7b. At the time of a collision, gunpowder within the gas generator 7a is ignited by a signal from an acceleration sensor and the air bag 7 expands. The air bag 7 breaks the cover 7b, projects on a floor surface 2a from the front and advances to a space between the floor surface 2a and a pedal 5. The air bag 7 functions as a stopper member receiving a heel part (b) of a foot (a) of an occupant and forward movement of the heel part (b) by inertia is prevented. Because the stopper member 7 does not normally project on the floor surface 2a, the degree of freedom of movement of the foot (a) of the occupant is not constrained. |
