Patent ID: 10458418

Abstract:
The ceiling fan includes: a body having a plurality of blades and an upper mounting pipe portion; a suspender which is fixed to a ceiling; a first pipe which is suspended from the suspender and suspends the body by the upper mounting pipe portion; and a second pipe which is accommodated in the inside of a lower portion of the first pipe and into which an upper portion of the upper mounting pipe portion is inserted. The first pipe, the second pipe and the upper mounting pipe portion are connected to each other by a connecting bolt which penetrates an overlapping part where the first pipe, the second pipe and the upper mounting pipe portion overlap with each other. A hollow projecting portion which projects from an outer peripheral surface of the second pipe is engaged with a recessed portion formed on an edge of a lower opening of the first pipe and a protruding portion formed on an outer peripheral surface of the upper mounting pipe portion thus restricting at least the relative movement among the first pipe, the second pipe, and the upper mounting pipe portion in the rotating direction of the blades.
