The invention aims at reducing the beating noise generated from motors of equipments placed in a galley unit of an aircraft. A galley unitof an aircraft includes a cabinetformed of honeycomb panels and the like. The cabinethas a counterfor cooking, and a compartmentformed under the counterfor storing service carts. A plurality of ovensfor heating warm dishes are provided above the counter. Each ovenhas a fan motor for making the inner heat even. If all the fan motors of the ovens are driven at the same rotation frequency, a beating noise will be generated from the motor and amplified through the compartment. Therefore, the rotation frequencies of the fan motors are slightly varied.
