Abstract
Brake apparatus (10; 110; 140) includes a transmission unit (75) for operatively connecting a brake pedal (12) to a master cylinder (17), and the transmission unit is capable of varying a ratio between an output amount of a push rod (86) connected to a master cylinder (17) and a movement amount of the brake pedal (12). Further, the transmission unit (75) is constructed such that, in a latter-half operation amount region (E2; E6; E9) of the brake pedal, the ratio of the operation amount of the brake pedal to the movement amount of the push rod is controlled, via the transmission unit, to increase in response to increase of the operation amount of the brake pedal.
