Claims

[Scope of utility model registration request]

A reservoir body that stores hydraulic fluid, a cap that closes the upper opening of the reservoir body, and an atmospheric chamber that is provided below the cap and is connected to the outside air and is connected to the surface of the hydraulic fluid. A flexible gasket forming a reservoir chamber, and a perforated baffle plate provided below the gasket at a slight interval, a slit passing through the gasket and facing the gasket. A protrusion is provided on the back surface of the cap and the upper surface of the buffer plate to abut a position near the slit and open the slit when the gasket is deformed due to the differential pressure between the atmospheric chamber and the reservoir chamber. A reservoir featuring:
