Air pump device and seat device

An air pump device, comprising:

• an electric pump unit that includes a pump mechanism and a motor that drives the pump mechanism, wherein the pump mechanism and the motor are integrated with each other;
• a case accommodating the electric pump unit;
• and
• an anti-vibration member arranged between the electric pump unit and the case, wherein
• the pump mechanism and the motor are aligned in an axial direction of the motor,
• the pump mechanism includes an inlet and an outlet in an axial end at a side opposite to the motor in the axial direction of the motor,
• the case includes a first wall and a second wall that are located at opposite sides in the axial direction of the motor and oppose the electric pump unit, and
• the anti-vibration member includes
• a first axial anti-vibration portion arranged between the electric pump unit and the first wall in the axial direction of the motor, and
• a second axial anti-vibration portion arranged between the electric pump unit and the second wall in the axial direction of the motor,
• wherein the first axial anti-vibration portion covers the inlet to function as an air filter of the pump mechanism.
