Fluid machine

A fluid machine, comprising:

• a housing that includes an inner circumferential surface;
• an operating member that is configured to draw fluid into and discharge the fluid from the housing;
• and
• a motor that is accommodated in the housing and is configured to rotate the operating member, wherein
• the motor includes:
• a stator that is fixed to the inner circumferential surface of the housing and includes a stator core, the stator core including a first end face and a second end face, the second end face being on a side opposite to the first end face;
• and
• a rotor that is arranged on a radially inner side of the stator, the rotor includes:
• a tubular portion that includes an inner circumferential surface and includes, in an axial direction of the tubular portion, a first end and a second end, the second end being on a side opposite to the first end;
• a magnetic member that is fixed to the inner circumferential surface of the tubular portion and includes a first end face and a second end face, the second end face being on a side opposite to the first end face;
• and
• a plug provided at one of the first end and the second end of the tubular portion,
• the fluid machine comprises two bearings that rotatably support the rotor,
• the tubular portion includes a first portion that protrudes in the axial direction in relation to the first end face of the stator core and the first end face of the magnetic member,
• the tubular portion includes a second portion that protrudes in the axial direction in relation to the second end face of the stator core and the second end face of the magnetic member,
• the first portion and the second portion of the tubular portion are rotatably supported by the two bearings, respectively,
• the magnetic member is spaced apart in the axial direction from the plug so that a space is defined inside the tubular portion by the tubular portion, the magnetic member, and the plug, and
• one of the two bearings is provided on a radially outer side of the space.
