Claims

[Scope of utility model registration request]

A cylindrical protrusion that forms a liquid outlet on the bottom of a reservoir tank that stores hydraulic fluid and a connection port that has an inner diameter larger than the outer diameter of the protrusion and that is formed in the boss of the cylinder body are connected through a sealing member. a master cylinder that is connected to the connecting port, the master cylinder being interposed within the connecting port so as to be movable in the axial direction by a predetermined distance between the bottom surface of the connecting port and the tip of the projecting portion and seatable on the tip of the projecting portion; a filtration member that filters the working fluid flowing between the reservoir tank and the connection port when seated at the tip of the protrusion; and a filter member interposed between the filtration member and the bottom surface of the connection port, A master cylinder comprising: a biasing member that biases the member toward the tip of the protrusion with a predetermined load so that the filtering member is normally seated on the tip of the protrusion.
