PURPOSE: Structure of an outer case made of synthetic resin is provided to reduce the weight and prevent the corrosion of the corner from rust by making the outer case of light synthetic resin, and to improve the rigidity by integrally forming a reinforcing member. CONSTITUTION: An outer case comprises an outer case body manufactured by injection molding synthetic resin; and a reinforcing member(12) integrally formed with the outer case to reinforce the outer case. The reinforcing member is formed of inverse L-shaped steel made of metal material. The inverse L-shaped steel is installed in the corner of the outer case body. The rigidity is improved, and rust is prevented with integrally forming the reinforcing member in the synthetic resin outer case body.
