摘要： A blower unit includes a rotation shaft, a centrifugal fan and a casing. The centrifugal fan has blades arranged around the rotation shaft. The casing has a wall part defining an opening. The ring part has a ring shape having a center coinciding with an axis of the rotation shaft. The ring part is provided at first axial ends of the blades and support the blades. The ring part includes an arcuate wall curved in a radially inward of the centrifugal fan. The centrifugal fan is housed in the casing such that the arcuate wall of the ring part is located radially inside of the opening of the wall part.

摘要： An electric blower includes an electric motor, a first fan, a second fan, a first casing and a second casing. The electric motor includes a motor body and a rotation shaft extending from the motor body only on one axial side of the motor body. The first fan is located to the one axial side of the motor body and defines a first axis of rotation aligned with the rotation shaft. The second fan is located to the one axial side of the motor body and further than the first fan from the motor body in an axial direction. The second fan defines a second axis of rotation aligned with the rotation shaft. The first fan and the second fan are driven by a driving force generated by the electric motor. The first fan is disposed in the first casing. The second fan is disposed in the second casing.
摘要翻译：电动鼓风机包括电动机，第一风扇，第二风扇，第一壳体和第二壳体。电动机包括电动机主体和仅在电动机主体的一个轴向侧从电动机主体延伸的旋转轴。第一风扇位于电动机主体的一个轴向侧面并且限定与旋转轴对准的第一旋转轴线。第二风扇位于电动机主体的一个轴向侧，并且比轴向上的电动机主体的第一风扇更远。第二风扇限定与旋转轴对准的第二旋转轴线。第一风扇和第二风扇由电动机产生的驱动力驱动。第一风扇设置在第一壳体中。第二风扇设置在第二壳体中。
