Claims

[Claims for Utility Model Registration] A driven shaft that carries a driven gear, a drive shaft that carries a drive gear that meshes with the driven gear, and a bearing that rotatably supports the driven shaft and the drive shaft are housed inside the case body. A stuff-in box is disposed on the front side of the case body and has a seal member storage hole through which the drive shaft passes and a seal member is stored, and a stuff-in box is provided in front of the seal member stored in the seal member storage hole. In a gear pump in which a storage hole closing member is attached to the stuff-in box for regulating movement of the storage hole closing member, a cutter for scraping off deposits for removing deposits on the outer circumferential surface of the drive shaft is attached to the storage hole closing member at its tip. A gear pump characterized in that a gear pump is provided such that a portion is disposed along an outer circumferential surface of the drive shaft.
