PROBLEM TO BE SOLVED: To appropriately perform filling of hydraulic liquid by pumping in a short time while improving productivity and economical efficiency by integrally molding a filter with a reservoir body. SOLUTION: An oil guide tube 2e is vertically projected on an upper wall 2n of the reservoir body 2. An upper opening of the oil guide tube 2e is set to be an oilhole 3. The filter 13 is integrally molded on a lower end interior of the oil guide tube 2e. An air hole 14 is provided on a sidewall between the filter 13 and the reservoir 2 by communicating with a storing liquid chamber 5 and the interior of the oil guide tube 2e. The air hole 14 is disposed on the upper side than the upper limit level gauge 2f. Even when the hydraulic liquid is filled up to the upper limit level gauge 2f, all of the air holes 14 are exposed on the liquid surface. COPYRIGHT: (C)2004,JPO
