ABSTRACT:
A hydraulic reservoir with fluid level detector includes a main body having an internal space for containing brake oil; a cap attached to the main body for covering a top opening of the main body; a diaphragm arranged across the top opening of the main body, the outer circumference of the diaphragm being held between the main body and the cap, and the space between the cap and the diaphragm communicating with the atmosphere; a reed switch fixed to the main body, a float provided with permanent magnet, so arranged as to be vertically movable in the internal space of the main body, the reed switch and the float with permanent magnet constituting a fluid level detector, and when the float with permanent magnet is positioned under a predetermined level, the reed switch being closed by magnetic force of the permanent magnet; an operating rod for pushing down the float, being vertically movable and able to be pushed down from the external against buoyancy of the float; and a cylindrical portion integrally formed with the diaphragm, being closed at the lower end, the operating rod being inserted into the cylindrical portion and the float being pushed down through the closed end of the cylindrical portion by the operating rod.
