請求の範囲第１項記載の歯車ポンプ。[Claims for Utility Model Registration] 1. In a gear pump in which a pair of gears mesh within a casing, the casing is divided into three parts, each having a thickness that is substantially the same as that of the gears, and the teeth of the pair of gears. It consists of an outer peripheral wall that contacts first, and a pair of side walls that contact both side surfaces of the pair of gears and are in close contact with both side surfaces of the outer peripheral wall, and penetrates through the one side wall and the outer peripheral wall. A gear pump characterized in that the both side walls and the outer circumferential wall are brought into close contact with each other by a bolt that is screwed and tightened to the other side wall, and the casing is sealed liquid-tightly. . 2. A through hole is provided that passes through the outer circumferential wall portion and the pair of side wall portions in a straight line, and a positioning pin is fitted into the through hole to temporarily fix the outer circumferential wall portion and the side wall portions. The gear pump according to claim 1 of the utility model registration claim.
