PROBLEM TO BE SOLVED: To easily mount and dismount a cap, a diaphragm plate, and a diaphragm in a reservoir and improve a supply property of brake liquid and maintenance workability. SOLUTION: A screw insertion hole 23 is formed in the diaphragm plate 12. Slits 24, 24 passing through a central axis of the screw insertion hole 23 are cross-formed in a thin film left in the screw insertion hole 23 to form four engaging pieces 12c in the thin film. A screw insertion hole 20 of the cap 11 and the screw insertion hole 23 in the diaphragm plate 12 are set on the same axis to insert a set screw 14 from the cap 11 side. The engaging piece 12c is engaged with a shaft 14a of the set screw 14 to temporarily assemble three parts of the cap 11, the diaphragm plate 12, and the set screw 14 in advance.
