PROBLEM TO BE SOLVED: To provide a fluid pump device capable of suppressing concentration of stress by shaft thrust when an impeller member is rotated and driven and suppressing breakage (creep). SOLUTION: This fluid pump device is provided with the impeller member 5 rotated and driven relative to a motor side case 1. On an impeller shaft 6 insert-molded in a supporting cylindrical part 1f of the motor side case 1 and supporting the impeller member 5 rotatably, a supporting member travel regulation part 6a is provided in a recessed condition in the direction crossing the shaft orthogonally in a part to be inserted. A supporting member stress dispersion part 6b curved to the direction crossing the shaft orthogonally is formed in the supporting member travel regulation part 6a. COPYRIGHT: (C)2006,JPO&NCIPI
