Abstract: A differential device is provided with: an input case having an axially directed end face; a differential gear set with side gears allowing a differential motion therebetween; dog teeth toothed toward the end face on an output case; a clutch structure engageable with the dog teeth and so structured as to couple the output case or the second side gear with the input case when engaged; an axially movable clutch member including an internal end and an external end exposed to the exterior; an axially movable armature including a magnetic material and in contact with the external end; a solenoid supported away from the end face, the solenoid generating a magnetic flux to attract the armature and, via the clutch member, set the clutch structure in mesh with the dog teeth; and a spring biasing the clutch member in a contrary direction.

Abstract: A flow straightener of a vehicle provided with a bumper and a cab disposed above the bumper includes a first opening section provided in the bumper and/or the cab and opened toward a front of the vehicle, and a second opening section connected to the first opening section via a connecting path and opened toward an outer side in a vehicle width direction from a location further on an inner side in the vehicle width direction than front wheels of the vehicle such that traveling wind led into the first opening section passes through a front wheel forward region defined as being behind the first opening section in a lower region of the cab and in front of the front wheels.
