PROBLEM TO BE SOLVED: To provide a gear pump which eliminates necessity for a subflow path without poor economy discarding a material resin. SOLUTION: In a gear pump constituted by providing a casing 1 having inlet/outlet flow paths, pair of gears meshed with each other to rotate in the inside of the casing 1 and bearings 212, 222 supporting rotary shafts 211, 221 integrally rotated with both of these gears, so as to transfer feed a fluid from the inlet flow path to the outlet flow path by meshing a pair of the gears rotated, fluid flow paths 213, 223 connecting the inlet/outlet flow paths are provided between a side surface of the bearings 212, 222 and a side surface of both the gears. |
