<P>PROBLEM TO BE SOLVED: To provide a pump deice capable of increasing suppressing force for suppressing peeling of a resin member covering a stator or the like from a partition member formed with a partition arranged between a stator and a pump chamber. <P>SOLUTION: The pump device includes the partition member 11 having the partition 11a arranged between a pump chamber arranged with an impeller and a rotor and a stator and preventing the inflow of fluid in the pump chamber to an arrangement location of the stator, and the resin member made of resin and formed to cover the stator. The partition 11a is formed in a substantially bottomed cylinder shape with a flange having a cylinder 11b, a bottom 11c, and a flange 11d, and the resin member covers the cylinder 11b and the bottom 11c, and is formed to cover one side surface of the flange 11d. On an outer circumferential surface of the cylinder 11b, a peeling prevention groove 11j for preventing peeling of the resin member from the partition member 11 is formed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
