Abstract

PURPOSE:To make it possible to mount a device body on the car room side of a toe board while laterally extending the device body with respect to a pedal by converting the rotation of a rotary shaft turned with the stepping of the pedal in a master cylinder, etc., to the axial movement of a piston. CONSTITUTION:Pistons 5, 6 inwardly go back by return springs 7, 8 when the brake pedal 3 of a master cylinder mounted on a toe board C is not stepped in, and a reverse tank T and front and rear brakes F, R are communicated to each other via piston chambers 14a, 14b. When the brake pedal 3 is stepped in under said situation, the respective pistons 5, 6 are outwardly pushed out against springs 7, 8 via guide pins 9, 10 which are guided into guide grooves 11, 12 by the rotation of a rotary shaft 15. Hereby, oil in piston chambers 14a, 15b is pressurized and forcedly sent via connecting oil passages 17a, 17b to the front and rear brakes F, R, allowing prescribed braking force to be generated.
