ロリツクブースタ装置のリザーブタンク構造。[Scope of Claim for Utility Model Registration] A hydraulic booster that uses hydraulic pressure to assist the brake pedal depression force, a hydraulic pump that generates hydraulic pressure to be supplied to the hydraulic booster,
In a hydraulic circuit in a hydraulic booster device, the hydraulic circuit is equipped with an accumulator that stores a part of the hydraulic oil pressurized by the hydraulic pump in an oil path leading to the hydraulic booster. A reserve tank is installed to store the hydraulic oil, and the reserve tank is provided with an outside air introduction hole to facilitate the supply and removal of the hydraulic oil. The air chamber is formed from a bellows member that can change the chamber volume according to the rise and fall of the oil level of the hydraulic oil. A reserve tank structure for a hydraulic booster device characterized by:
