摘要： PROBLEM TO BE SOLVED: To provide a vehicle drive unit capable of outputting sufficient driving force. SOLUTION: A driving high-output generator 44 is driven by an engine 20. A DC electric motor 30 is directly driven by energy from the generator 44. An driving generator output voltage control circuit 60 controls the output voltage of the generator 44 by field current control of the generator to control the electric motor 30. The driving force to be generated in the electric motor 30 is controlled by field current control of the electric motor 30. When an output more than the single output characteristic of the generator is requested, the field current of the electric motor 30 is controlled in addition to the field current control of the generator 44.

摘要： PROBLEM TO BE SOLVED: To prevent rainwater infiltration, and damp casing vibration excitation force by utilizing irregularity which is formed at the mating faces of split cylindrical casings, and inserting an O-ring into a faucet for fixing the split casings with each other. SOLUTION: A tubular casing 7 is formed by a light member such as a resin of non-magnetic material, and is constituted of right and left of cups 7b, 7c which is split into two pieces at a substantially central vertical surface in the axial direction of a rotating machine. By forming a groove part 7f of a ring shape and a protrusion 7g at the split surface which are fitted to each other, the stress generated at the split surface at the time of fixing work by a fitting leg 7d is received by one casing 7b to suppress the opening of the split surface to be minimum. To improve waterproofing, a small-diameter O-ring 9 which is an elastic member is positioned in the faucet part consisting of the annular groove part 7f and the protrusion part 7g with irregularities, which is fitted to each other. It is thus possible to completely seal rainwater infiltration, even under a harsh environmental condition with the strength of the split surface maintained.

摘要： PURPOSE:To reduce noise by disposing a motor, a fan, a scroll and a dust collecting mechanism inside of a door and side panels. CONSTITUTION:Fans 7 are rotated by motors 6 disposed inside of a plurality of doors, and air 10 is sucked up from the passenger compartment by scrolls 8. The sucked up air is led through a filter 4 so that bulky dust is caught thereby, and is then led through an electric dust collecting part 5 where fine dust such as smoke particles are electrically attracted so that the air is turned into purified air which is then discharged from a discharge port 2. With this arrangement, air is efficiently substituted around a passenger, and is divided into several streams, thereby it is possible to divide and reduce the flowing sound of the air, the operating sound of the motor and the like.
