Claims

[Scope of utility model registration request]

A reservoir body that has an internal space and has an opening at the top and a supply section at the bottom, and the reservoir body that closes the opening and is fitted with relative rotation. a flexible diaphragm disposed between the cap and the opening with its outer circumferential edge pressed between the cap and the opening; and a low-friction sliding ring disposed between the outer circumferential edge of the diaphragm and the cap. and a reservoir in which the diaphragm and the sliding ring are coupled to each other via a concavity and convexity, an outer part of the diaphragm located on the outer peripheral side of the joint between the sliding ring and the diaphragm, and a cap on the outer side of the diaphragm. A hydraulic fluid reservoir comprising a convex portion extending toward the cap and a concave portion into which the convex portion fits.
