Abstract

A rotor blade (6) includes: a blade attachment plate (4) fixed to a shaft of a motor to rotate; and a blade (5) joined to the blade attachment plate (4) by fastening members and rotating together with the blade attachment plate (4) to form airflow along the shaft. The blade (5) includes a blade attaching portion joined to the blade attachment plate (4) by the fastening members, and a blade portion to generate the airflow. In an axial direction of a rotational axis (AX) of the blade attachment plate (4), a center of gravity of the blade (5) is located downstream of an axially perpendicular plane (L) that is orthogonal to the rotational axis (AX) of the blade attachment plate (4) and passes a midpoint of a line connecting a center of a plate thickness of the blade (5) at a portion at which a forward-most fastening member among the fastening members in a rotational direction of the blade attachment plate (4) fixes the blade attaching portion to the blade attachment plate (4) and a center of a plate thickness of the blade (5) at a portion at which a rearward-most fastening member among the fastening members in the rotational direction fixes the blade attaching portion to the blade attachment plate(4).
