PURPOSE:To reduce the frequency of generation of high pressure in a brake device by quickly increasing the pedal stamping force at the stage as going beyond the normal braking zone, and giving the operator a sense of stroke end. CONSTITUTION:One end of a tensile spring 9 is coupled with a frame, while the other end is coupled with one end of a link 11 which is fastened to the frame rotatably. The tensile spring 9 is in advance given the initial tensile force, and rotation of the link 11 due to this initial tensile force is hindered by a stopper 12. The other end of the link 11 is arranged facing a link arm 2 of a brake pedal 1 with possibility of contacting. When the brake pedal 1 is stamped to approx. the middle position of pedal stroke S to cause the link arm 2 to contact the link 11, the initial tensile force of the tensile spring 9 is added to the pedal stamping force, and the operator is given a sense of stroke end expressly. |
