Abstract
An ECU for an engine is held in a circuit holding member provided in an air cleaner cap of an intake device. A space between the ECU and the circuit holding member is filled with a potting material, so that the ECU is fixed to the circuit holding member. As a result, the ECU can have high shakeproof properties not to cause malfunctions and not to be damaged by vibrations.
