Variable pedal feeling adjustment device

A variable pedal feeling adjustment device to adjust a pedal feeling provided for a driver by hydraulic pressure caused by pedal effort of a driver, comprising:

• a pedal simulator including a simulator block formed with an oil hole at an upper portion thereof and a bore therein, the oil hole being connected to a master cylinder through a passage to receive hydraulic pressure caused by pedal effort of a driver and the bore communicating with the oil hole, a damping housing slidably installed to a lower portion of the bore to seal a lower end portion of the bore while being restricted in rotation, a first reaction unit provided in the bore and configured to provide reaction force by being pressurized by oil supplied from the master cylinder, and a second reaction unit supported by the damping housing and configured to provide reaction force by being compressed by pressurization of the first reaction unit;
• an auxiliary simulator including an auxiliary chamber connected to the passage through a connection passage, an auxiliary piston slidably provided in the auxiliary chamber, and an auxiliary spring to elastically support the auxiliary piston;
• and
• a control valve installed to the connection passage to control transfer of hydraulic pressure to the auxiliary chamber.
