PURPOSE:To avoid the coming off of front and rear guards from the retaining grooves of a lower cushioning body and permit a stable and retainable packing of an electric fan by providing a projection for insertion between the ribs of a guard between lower retaining grooves in supportable engagement with the outer peripheral rings of front and rear guards. CONSTITUTION:There are provided a retaining recess part 26 formed of a tetragonal notch serving to curtail the amount of the molding material of a lower cushioning body 3, lower retaining grooves 28 and 29 on the bottom thereof, with which outer peripheral rings 15 and 18 are engaged, a projection 35 thereon between the grooves 28 and 29 for insertion between the ribs 19 of a rear guard 7 and side retaining grooves 30 and 31 on the upper corners of the retaining recess part 26, with which the outer peripheral rings 15 and 18 are engaged. A front guard 6 is supported by the lower retaining groove 28 and the side retaining groove 30 and the rear guard 7 is supported by the lower retaining groove 29 and the side retaining groove 31. Therefore, the front and rear guards 6 and 7, when supported by all of the grooves 28, 29, 30 and 31, are supportably spread upwardly from the lower retaining grooves 28 and 29. |
