Abstract
An air compressor includes a cooling fan having a back plate serving as a plate shape part formed on a flat plate, a normal line thereof being set to a direction along a rotational shaft of a motor, blades extending parallel with the rotational shaft from an inner side of the back plate towards an outer periphery thereof and being centrifugally formed on the back plate, and a ring part having a cylindrical shape substantially parallel with the rotational shaft and extending from the back plate towards a heat generation surface. When the motor is operated, exterior air sucked by the cooling fan is guided to a central part thereof, flows towards an outer periphery thereof along the back plate, deflected by the ring part, flows towards and collides with the heat generation surface and further flows radially.
