Summary:PROBLEM TO BE SOLVED: To solve problems that oil contained by an electric machine may coke as heat is accumulated and temperature of the electric machine considerably rises and mechanical characteristics may be lost as a stator is overheated. SOLUTION: In the accessory box in the aircraft engine for supporting the electric machine 16 such as an alternator wherein a rotor 14 is rotation-guided by a bearing 24 supported by a supporting part 40 of a material of small coefficient of thermal expansion, the support part itself is supported by a stator cover 42 working as a heat bridge between a stator main body 20 of the electric machine and the housing 10 of the accessory box.
