1. A pedal simulator comprising:
a housing having a first surface and a plurality of guide holes inwardly extending side by side from the first surface of the housing;
a piston part including (1) a first surface facing the first surface of the housing and (2) a plurality of piston rod units extending side by side from the first surface of the piston part and configured to slidably move within the plurality of guide holes, respectively, when the piston part moves toward the housing;
a plurality of damper parts respectively disposed within the plurality of guide holes of the housing and configured to be compressed by the plurality of piston rod units, respectively, when the plurality of piston units slidably moves inwardly of the housing through the plurality of guide holes, respectively, and press the plurality of damper parts, respectively,
wherein the plurality of damper parts includes first and second damper parts, the first damper part being configured to be compressed sooner than the second damper part when the plurality of piston rod units slidably moves toward the plurality of damper parts, respectively,
wherein the piston part further includes:
a piston body unit having first and second sides; and
a piston pressing unit disposed at the first side of the piston body unit, and
the second side of the piston body has the first surface of the piston part,
wherein the plurality of piston rod units includes:
a first piston rod unit disposed at the second side of the piston body unit and configured to press the first damper part; and
a second piston rod unit disposed at the second side of the piston body unit, spaced apart from the first piston rod unit and configured to press the second damper part,
wherein the first and second piston rod units have respectively different lengths,
wherein the first damper part is disposed to face the first piston rod unit and compressed by the pressure from the first piston rod unit,
wherein the second damper part is disposed to face the second piston rod unit, spaced apart from the first damper part, and compressed by the pressure from the second piston rod unit, and
wherein the first damper part includes:
a first damper body unit disposed at the housing;
a first damper contact unit spaced apart from the first damper body unit and configured to move by the first piston rod unit in contact with the first damper contact unit;
a connection unit having a first side movably disposed on the first damper body unit and a second side disposed on the first damper contact unit;
a sensor unit disposed on the first damper body unit and configured to detect a position of the first piston rod unit; and
a spring unit having a first side in contact with the first damper body unit and a second side in contact with the first damper contact unit, and configured to provide an elastic force to the first damper contact unit.
