Work machine

A work machine, comprising:

• a motor;
• an output shaft, rotated by driving of the motor;
• a first fan, being a centrifugal fan fixed to the output shaft and rotating integrally with the output shaft;
• a second fan, being a centrifugal fan located on one side of the first fan in an axial direction of the output shaft, fixed to the output shaft, and rotating integrally with the output shaft;
• and
• a rectification member, accommodating the first fan and the second fan therein, and, in response to the output shaft rotating to one side in a rotation direction, causing a first airflow blown out from the first fan and a second airflow blown out from the second fan to join together and flow out toward one side in the axial direction, wherein
• the rectification member comprises a rectification section in which the second airflow is rectified so as to flow to the one side in the axial direction and is suppressed from flowing to the other side in the axial direction, wherein
• the rectification section is arranged radially outside the output shaft with respect to at least the second fan, and changes a direction of the second airflow into toward the one side in the axial direction;
• and
• a sub rectification section is provided radially outside the first fan;
• and
• the sub rectification section is arranged on the other side in the rotation direction with respect to the rectification section, and is formed in a rib shape extending along a direction that is inclined to the one side in the axial direction as going toward the one side in the rotation direction as viewed in a radial direction of the output shaft.
