Abstract

PURPOSE: To improve the feeling of a brake in braking, by providing a reaction plate with a finger which is cut and erected in the radial direction in accordance with a reaction lever and curved for urging forward or backward.
CONSTITUTION: The curved shape of a finger 24 is changed forward or backward depending on the fluctuation in a reaction force applied from an output rod 18 to a reaction plate 22. At that time, the center 23a of the fulcrum engagement portion 23 of both the finger 24 and a reaction lever 19 is displaced in the radial direction. As a result, the lever ratio of the lever 19 is altered so that the ratio of increase and decrease in a reaction force transmitted through a valve plunger 10 and an input rod 9 to a brake pedal not shown in the drawing is made nonlinear. For that reason, the ratio of the increase in the reaction force transmitted to the brake pedal is reduced. The increase in the reaction force transmitted to the brake pedal is relatively small even if the thrusting force of a power piston 3 increases. The brake pedal can thus be advantageously operated.
