Abstract: PROBLEM TO BE SOLVED: To improve fuel consumption by avoiding frequent operations of an engine for only charging as much as possible, regardless of the stopping of a vehicle or the traveling of the vehicle. SOLUTION: When a charging residual amount of a battery 4 for supplying power to an electrical motor generator 2 and an air conditioning unit 6 becomes equal to or lower than a charging starting target value, the electrical motor generator 2 is driven by the engine 1 for traveling to charge the battery 4. By setting the charging starting target value during the operation of the engine 1 for traveling to be higher than that during the stopping of the engine 1, charging tends to be required during the operation of the engine 1.

Abstract: PROBLEM TO BE SOLVED: To lower an insertion force during connection without impairing sealability. SOLUTION: A female side tapered surface 91b corresponding to a ring outer side tapered surface 10b is formed at the positions of the ring outer side tapered surface 10b and a sealed surface 91a corresponding to a backup ring 10 on the outer peripheral side of the backup ring 10. The inside taper angle α of male side tapered surface 81b/ring inner side tapered surface 10a and the outside taper angle β of ring outer side tapered surface 10b/female side tapered surface 91b are related to be inside taper angle α>(outside taper angle β)>0°. Accordingly, since the outer peripheral side of the backup ring 10 is not so formed that its cylindrical faces are fitted to each other but so formed that the cylindrical faces are brought into contact with each other after being inserted, and also a final compression tolerance can be set with a push-in dimension after the insertion without inserting while reducing the compression tolerance from an initial stage. Thus, the insertion force during connection can be lowered. COPYRIGHT: (C)2007,JPO&INPIT
