A fuel-saving drive recommendation system is mounted on a vehicle that includes a step-gear automatic transmission of which a gear is shifted in response to a gear instruction signal. The fuel-saving drive recommendation system calculates a required driving force based on an amount by which an output operating component is operated by a driver and a gear of the automatic transmission, makes determination for fuel-saving drive for the vehicle based on the required driving force and notifies the determination result. The fuel-saving drive recommendation system calculates a required driving force for performing output control on an engine and a required driving force for determining whether it is a fuel-saving drive state. A determination gear signal different from the gear instruction signal is used when the determination required driving force is calculated, and is changed to coincide with the gear instruction signal that has been changed.

A diagnostic system for an automatic transmission is provided in which a microcomputer determines that torque that can drive the driving wheels of the vehicle is not transmitted to an output shaft of the automatic transmission when the vehicle is stopped and the ignition key is operated to the OFF position, and performs forced energization of solenoids of solenoid valves associated with respective friction devices of the transmission, while monitoring current passing through the solenoid valves. If the current monitored does not match the current for energizing any of the solenoids, the microcomputer determines that the corresponding solenoid valve is at fault. Thus, the diagnostic system appropriately determines the presence of a fault of each solenoid valve for controlling the hydraulic pressure to each friction device, with increased flexibility and freedom.

An air-conditioning duct is provided inside a car console box that has an ornamental portion. The duct has an air passage for conducting conditioned air from an air conditioner to the passenger compartment. The air passage is defined by a first wall portion formed by the ornamental portion, a second wall portion opposed to the first wall portion, a third wall portion located between the first and the second wall portions, and a fourth wall portion located between the first and the second wall portions. The fourth wall portion is opposed to the third wall portion. Each wall portion has an inner surface exposed to the interior of the air passage. A pair of boundary lines are defined on the inner surface of the first wall portion at boundaries between the first wall portion and the third and fourth wall portions. A dew condensation suppression portion is provided on the inner surface of the first wall portion between the pair of the boundary lines. A space is defined between the dew condensation suppression portion and each boundary line. When the thickness of the dew condensation suppression portion on the first wall portion is expressed by T (mm), and the sum of the widths of the spaces is expressed by D (mm), the thickness T and the sum D of the widths satisfy the following expression (1).+2 mm(&#x3e;0 mm)&#x2003;&#x2003;(1)

A buckle is provided with a female memberhaving first and second engaging portionsand, and a male memberhaving first and second engagement piecesand. By inserting the male memberinto the female member, the first engaging portionengages with the first engaging piece, and the second engaging portionengages with the second engaging piece, thereby, female memberand male memberare connected. The male memberand female memberare not separated, unless engagement between first engaging pieceand first engaging portion, as well as engagement between second engaging pieceand second engaging portion, are released by means of both a first operating portionand a second operating portionwhich are separately provided on the front and rear of female memberbeing pressed inwardly.

A console box of the present invention has a box main body, a pair of sidewalls, and an armrest. The box main body is located between the sidewalls, and the armrest is located above the box main body. Each sidewall has a guide groove extending in the moving direction of the vehicle. The armrest has a pair of engaging pins. Each engaging pin is engaged with and slides along one of the guide grooves. Thus, the armrest smoothly slides along the moving direction of the vehicle.
