Disclosed is a device to regulate a variable pedal feeling. According to the present invention, the device to regulate the variable pedal feeling which regulates a stroke distance of a repulsive piston disposed in a pedal simulator providing a pedal feeling to a driver, includes: the pedal simulator having an oil hole formed on the upper portion thereof in such a manner to be connected to a master cylinder to receive an hydraulic pressure in accordance to the driver′s pedal force, a simulator block having a bore formed therein to communicate with the oil hole, a first repulsive part and a second repulsive part disposed serially in the bore in such a manner to be sequentially pressurized by the pedal force, and a damping housing supporting the second repulsive part disposed on the lower portion of the bore in such a manner to be restricted in the rotation thereof; and an actuator having a spindle screw-coupled to the damping housing and a motor connected to the spindle to provide a rotary force, wherein a first repulsive piston of the first repulsive part provides the pedal feeling to move by a first stroke distance and brought into contact with a second repulsive piston of the second repulsive part, and the second repulsive piston of the second repulsive part pressurized by the first repulsive piston moves by a second stroke distance to provide the pedal feeling, such that the damping housing linearly moves in accordance with the forward and backward rotation of the spindle in such a manner to be varied in position, thus varying the position of the second repulsive part in the state where the second stroke distance of the second repulsive part is fixated and adjusting the first stroke distance of the first repulsive part. |
