Rotation support device for flying object

Abstract

A rotation support device for flying object has a stationary body having double-row outer ring raceways on an inner circumferential surface thereof and capable of supporting a motor stator, a rotating body having double-row inner ring raceways on an outer circumferential surface thereof and capable of supporting a motor rotor and a propeller, and a plurality of rolling elements arranged between the double-row outer ring raceways and the double-row inner ring raceways so as to be able to roll freely, at least one outer ring raceway of the double-row outer ring raceways directly formed on the inner circumferential surface of the stationary body and/or at least one inner ring raceway of the double-row inner ring raceways directly formed on the outer circumferential surface of the rotating body 3.
