| 摘要 |
The blower of the present invention comprises a gas blowing part which holds an impeller which blows gas, a motor part which holds a rotor which makes the impeller rotate, and a partition wall part which partitions the gas blowing part from the motor part. The top end part of the rotor in the axial direction passes through the partition wall part and supports the center of rotation part of the impeller present inside the gas blowing part. At the through hole of the partition wall part through which the top end part of the rotor in the axial direction passes, a noncontact type shaft seal is arranged. Further, the surface of the partition wall part facing the impeller is formed with a groove for trapping foreign matter. |
