Claims14
A pedal simulator comprising:
- a first damper housing;
- a second damper housing coupled to the first damper housing;
- a first bearing unit rotatably disposed on the second damper housing;
- a damper piston unit slidably accommodated inside the first damper housing;
- a damper coupled to the damper piston unit, accommodated inside the first damper housing, and compressed by a movement of the damper piston unit;
- a damper pressing rod coupled to the damper piston unit to press the damper piston unit;
- and
- a first elastic unit disposed between the damper pressing rod and the first damper housing to elastically support the damper pressing rod,
- wherein the first damper housing comprises:
- a damper housing body having one side to which the second damper housing is coupled, wherein the damper piston unit and the damper are disposed in the damper housing body;
- and
- a seating portion protruding from an inner peripheral surface of the damper housing body and extending along a circumferential direction of the damper housing body, the damper piston unit being seated on the seating portion by an elastic force of the first elastic unit,
- wherein the seating portion includes one or more step portions recessed in an outer surface of the seating portion.
