Abstract: An axle disconnect system is provided whereby axles of a tandem or multi-axle vehicle may be easily and quickly engaged and disengaged as required and whereby the ring gear and differential gears remain stationary when the axle is disengaged.

Abstract: A passenger restraint system actuates a passenger restraint device more appropriately in situations where a vehicle rolls over. When the steering is turned in the same direction as the roll direction before the roll angle of the vehicle exceeds a threshold value, the passenger restraint system assumes the vehicle is headed toward recovery from the rollover behavior and subtracts a predetermined angle successively from the roll angle in accordance with the steering angle. Thus, the passenger restraint device is not actuated when the steering operation will stop the rollover behavior. On the other hand, the passenger restraint device is actuated when the steering is not operated and the vehicle rolls over, and when operation of the steering begins to effect a recovery but ultimately the vehicle rolls over anyway. In this situation, the passenger restraint system bypasses executing subtraction from the roll angle after the roll angular velocity exceeds a prescribed angular velocity.

Abstract: An electrically driven power steering apparatus is structured such that a large impact on a rack shaft (22) occurs upon an impingement of a steering stopper, and, even when an axial force acting on a ball bearing (25) of a presser member (30) becomes zero, a rotation of the presser member (30) is hindered by caulking c at a thin plate member (30b).
