DEADMAN BRAKE DEVICE IN VEHICLE

PROBLEM TO BE SOLVED: To provide a deadman brake device for a vehicle having some characteristics such as a reduction of pedal treading pressure, elimination of fatigue feeling of an operator for carrying out an operation of a brake pedal, a manufacturing cost reduction through its simple structure, prevention of application of a braking force for the vehicle against a mere slight returning of the tread pedal and showing a superior operating characteristic. SOLUTION: This deadman brake device comprises a pedal lever 25 having a pedal part 26, a turning shaft 21 turned in response to an amount of tread of the pedal 26, a pedal biasing means 28 for biasing the pedal lever 25 and a wire-cooperating means 44 for releasing a brake wire 41. The pedal biasing means 28 comprises a biasing arm 29 fixed to the turning shaft 21, a spring mechanism 34 pivotally attached to a vehicle floor 19 through a pivot 33, and a connecting shaft 30 for connecting the biasing arm 29 with the spring mechanism 34. A resilient force acting line S1 for connecting the connecting shaft 30 with the pivot 33 approaches the center of the turning shaft 21 in response to a treading amount of the pedal 26.
