Claims

[Scope of utility model registration request]

A ring comprising a ring portion and a stem portion integrally provided at one end of the ring portion, an axial fan disposed in an air passage formed by the ring portion, and an inlet side of the axial fan. and an electric motor supported by the stem portion and driving the axial fan, wherein the stem portion of the shroud is formed separately from the ring portion and is joined to the ring portion. In order to reduce the area that obstructs the flow of air at the joint, both ends of the ring part are formed as venturi parts that open outward, and the stem part is connected to the ring-shaped holding part that holds the electric motor. 1. A shroud for an electric blower fan device, comprising an arm portion for connecting a holding portion to the ring portion, the width of the connecting portion of the arm portion to the ring portion being as small as possible.
