STROKE SIMULATOR

摘要

Provided is a stroke simulator capable of suppressing occurrence of inclination of a piston with respect to a sliding surface formed in a cylinder. The stroke simulator includes a simulator piston which is displaced by sliding on a sliding surface formed in a first cylinder, and a first return spring which is housed in the first cylinder and applies, to the simulator piston, a reaction force which is generated by an elastic deformation of the spring under a pressing force due to a displacement of the simulator piston, and generates the reaction force which is applied to the simulator piston as a brake reaction force for a brake operating element. The stroke simulator is characterized in that a cup seal for sealing a gap formed between the sliding surface and the simulator piston is mounted in the middle in the axial direction of the sliding surface.

1. A stroke simulator comprising:
a simulator piston which is displaced by sliding on a sliding surface formed in a first cylinder, in response to a hydraulic pressure which is generated by a hydraulic pressure generating unit due to an operation of a brake operating element by a driver; and a reaction force generating unit which applies a reaction force corresponding to a displacement of the simulator piston to the simulator piston, the stroke simulator generating the reaction force which is applied to the simulator piston as a brake reaction force for the brake operating element, wherein the sliding surface is formed in a part of the first cylinder, wherein the stroke simulator includes a second cylinder, which is coaxially formed in communication with the first cylinder and houses the reaction force generating unit therein, and wherein a cup seal is attached to a gap formed between the simulator piston and the sliding surface in the middle in the axial direction of the sliding surface.
