The electronic apparatus includes a circuit board on which electronic component is mounted and a chassis housing the circuit board. The chassis is provided with a biasing force applying member applying a biasing force to at least one of top and bottom surfaces of the circuit board to hold the circuit board in position such that the circuit board is allowed to be displaced in a direction parallel to a plane of the circuit board.

Electronic apparatus including circuit board chassis

An intake module for a vehicular engine has a casing that is constructed of an air cleaner housing portion and an electronic control unit (ECU) housing portion. The air cleaner housing portion that houses an air cleaner is mounted on the engine. The ECU housing portion that houses an ECU is connected with the air cleaner housing portion. A plurality of reinforcement ribs is formed on an outer periphery of the ECU housing portion.

Intake module having integrally housed ECU

An intake module has an electronic control unit (ECU) housing portion that houses an ECU. The ECU housing portion is provided in a manner that a lateral direction of the ECU housing portion is approximately coincident with a direction of an intake air passage that is located upstream from the ECU housing portion. Intake air is blown to an air blown area that is located on one side of the ECU housing portion. Heat-producing components and low heat-resistant components are mounted in the air blown area and in an area away from the air blown area, respectively. A plurality of heat-radiating fins is arranged in the air blown area along with a stream of the intake air.
