Abstract: An electronic device mounting structure for fitting an ECU (electronic device) in an open space formed in a device mounting housing and for holding the ECU fitted in the open space by a holding finger formed on the device mounting housing, includes a stopper formed in the device mounting housing so as to be juxtaposed with the holding finger, the stopper being configured to prevent the ECU from falling out of the device mounting housing.

Abstract: In an attachment structure, a vehicle-mounted electronic device is attached to a receiving box using an adjusting member for adjusting a difference between an external dimension of the electronic device and a dimension of a receiving space of the receiving box for receiving the electronic device. The adjusting member has an insertion-coupling device for insertion-coupling the adjusting member and the electronic device, and a first catch-coupling device for catch-coupling the adjusting member and the receiving box. The first catch-coupling device is an appended claw-receiving part that corresponds to a flexible claw on the receiving box, and the direction of insertion-coupling of the insertion-coupling device and the direction of catch-coupling of the first catch-coupling device are different.

Abstract: A power train arrangement structure for a vehicle, in which an engine and a transaxle for transmitting the drive power outputted from the engine to the axles of front wheels are so arranged in an engine room at the front side of a vehicle body as to have their individual axes in the widthwise direction of the vehicle and in which lower arms for holding the front wheels are supported at two portions in the longitudinal direction of the vehicle. This arrangement structure is characterized in that the foremost end positions of the engine and the transaxle, as taken in the longitudinal direction of the vehicle, are generally aligned with the foremost end positions of the lower arms, as taken in the longitudinal direction of the vehicle, and in that the rearmost end positions of the rigid portions of the engine and the transaxle, as taken in the longitudinal direction of the vehicle, are generally aligned with the rearmost end positions of the lower arms, as taken in the longitudinal direction of the vehicle.
