The bleeding port is configured to be in communication with the reservoir chamber. The bleeding port has a bleeding-port inner diameter. The connecting port is configured to connect the reservoir chamber and a hydraulic chamber. The hydraulic chamber is at least partially defined by a piston. The reservoir structure includes an intermediate port through which a fluid is to flow from the connecting port to the bleeding port when bleeding the hydraulic reservoir. The intermediate port has an intermediate-port inner diameter smaller than the bleeding-port inner diameter. The bleeding plug is configured to be attached to the bleeding port.
