PURPOSE: An oil reservoir tank of a brake master cylinder is provided to prevent oil from flowing to a gap between an oil inlet and a reservoir cap even if a gasket is deformed due to a temperature change. CONSTITUTION: An oil reservoir tank of a brake master cylinder comprises an oil reservoir, a reservoir cap(30), a gasket(40), and a deformation preventing unit(50). The oil reservoir stores oil. An oil inlet is formed in one side of the oil reservoir. The reservoir cap opens and closes the oil inlet of the oil reservoir. The gasket seals a gap between the oil inlet and the reservoir cap. The deformation preventing unit is protruded from the oil reservoir in order to prevent an oil leak when the gasket is deformed. |
