PROBLEM TO BE SOLVED: To provide a vehicular brake system which has good mountability on a vehicle and the durability and operational feeling of which can be improved.SOLUTION: The vehicular brake system includes: an operational rod 16 for transmitting operational force of a brake operation member 71 to an input piston 15; a cylindrical first receiving part 29 disposed on an outer peripheral side of a front portion of the operational rod while being separated from the operational rod; a cylindrical second receiving part 30 disposed on the surrounding of a rear portion of the operational rod; a return spring 27 disposed between the first and second receiving parts and energizing the operational rod in a direction where the operational rod is returned to an initial position; a cylindrical stopper member 21 for supporting rear ends of a fail spring 36 and a fail cylinder 12 and restricting forward movement of equal to or more than predetermined distance of the fail cylinder; and a cylindrical swing member 28 disposed on a front end of the first receiving part and having a pressurization surface 28a formed into a projected arcuate shape. The stopper member has a recessed arcuate shaped receiving hole 21e on a rear part, and the pressurization surface contacts the receiving hole in a slidable manner. |
