Claim 5:
6. A motor-integrated fluid machine to suction a fluid from a suction port and discharge the suctioned fluid from a discharge outlet, the machine comprising:
a shaft portion at a center of a rotation axis;
a rotating portion configured to rotate around the shaft portion;
an outer peripheral portion on an outer periphery of the shaft portion; and
a motor configured to rotate the rotating portion,
wherein the rotating portion is rotatably supported on the shaft portion so that a shaft portion side is a fixed end side and an outer peripheral portion side is a free end side,
wherein the motor is an outer peripheral drive motor configured to apply power from the outer peripheral portion to rotate the rotating portion,
wherein the rotating portion includes:
a plurality of blades provided side by side in a circumferential direction of the rotation axis, and
a rotation outer peripheral portion provided on an outer peripheral side of the plurality of blades,

wherein the motor includes:
a rotor side magnet in the rotation outer peripheral portion, and
a stator side magnet in the outer peripheral portion facing the rotor side magnet,

wherein the plurality of blades includes a first blade and a second blade,
wherein at least a predetermined portion of the first blade and at least a predetermined portion of the second blade are located at different positions in an axial direction of the rotation axis, and
wherein a surface formed in an end portion on a suction port side of each of the plurality of blades during rotation is defined as a rotor plane, and
wherein, in the plurality of blades, the rotor plane in a portion on an outer peripheral side of the first blade and the rotor plane in a portion on an outer peripheral side of the second blade are in the same plane, and wherein a portion on an inner peripheral side of the first blade is closer to the suction port side than a portion on an inner peripheral side of the second blade in the axial direction of the rotation axis such that the rotor plane in the portion on the inner peripheral side of the first blade and the rotor plane in the portion on the inner peripheral side of the second blade are not in the same plane.
