Abstract

PURPOSE:To simplify connection between an electric fan main body and a stand by forming said main body detachable on the stand at the central part of a guard body equipped with a motor inside. CONSTITUTION:Blades 10 and an outside rotor 8, both pivoted on a front end projecting part of a fixed shaft 19 by means of a bearing 16, are prevented from falling out by means of a spinner 9. A rear end projecting part of the fixed shaft 19, piercing through a fitting plate 5, fixes a support plate 17 to the fitting plate 5 by screwing a nut body 24 to a screw part 23. The electric fan main body 1 can be disassembled by detaching the spinner 9 and the nut body 24. Thus, action of the external force on the connection part can be reduced.

(b) Prior art As a technology prior to the present invention, Japanese Patent Application Laid-Open No. 56-135792
There is an electric fan described in the publication. The electric fan has an electric motor attached to the center of the inner surface of the card body, and a fan main body formed by fitting blowing blades to the electric motor and supported by a stand at the lower part of the guard body. Therefore, although attempts have been made to make the electric fan thinner, the center of gravity of the main body of the electric fan is far from the support part of the stand, and a large force acts on the support part, so it is necessary to support it with sufficient strength. As a result, the structure of the connecting portion between the main body of the fan Jiff machine and the stand becomes large and complicated.
