<p>PROBLEM TO BE SOLVED: To provide structure to more exactly set a limit value of burden to be transmitted to lower limb via a pedal tread and to reduce increase of a manufacturing cost of a pedal separating part in the structure to bisect a pedal to limit the increase of the burden in the case of operation of a large external force such as the case of collision between vehicles. SOLUTION: The pedal is constituted by fastening a first pedal arm 1 with a second pedal arm 2 by a revolving shaft pin 3 and a breaking shaft pin 4, operated by using a pedal rotational center 5 as a fulcrum and an operating force is generated in a pressurization pin linkage part 6. When a force on pedal exceeds a prescribed limit of the force on pedal, the breaking shaft pin 4 is broken mainly by a shearing force, the second pedal arm 2 is rotated around the revolving shaft pin 3 and no excessive force is applied to a lower limb part, etc., of a crew in the case of collision, etc.</p> |
