摘要： A motor-driven wheel includes a wheel disc, a wheel hub, a knuckle, a hub bearing, a constant-velocity joint, an in-wheel motor, and a spring. The center of swing of the constant-velocity joint is placed closer to the outside of the vehicle relative to the hub bearing. Since such components of the constant-velocity joint as an inner race, balls and a cage are placed differently in position from the hub bearing, the hub bearing can be reduced in diameter. An outer race of the constant-velocity joint is integrated with the wheel hub into a single part and has an opening facing the outside of the vehicle. Since the opening is large and shallow, the work of installing the cage, balls and inner race and securing them with a snap ring is facilitated.

摘要： A motor-driven wheel includes a wheel disc, a wheel hub, a decelerator, a knuckle, a hub bearing, a constant-velocity joint, an in-wheel motor, and a spring. Since the decelerator is placed closer to the outside of the vehicle relative to the hub bearing, the space where the in-wheel motor is to be mounted can readily be secured. Further, balls are arranged along a spherical external surface of an outer race and the outer race is supported swingably in the axial direction. Thus, even when a great axial force is exerted, the axial force can be endured. The outer race can be supported swingably and rotatably with respect to the wheel hub.

摘要： An image forming apparatus with an image bearing member and a charging member for contactably charging the image bearing member. The charging member is provided within an exchangeable unit. An electric power containing an AC component is applied to the charging member, and adjustments are made to the magnitude of the AC component. When the exchangeable unit is exchanged, the magnitude of the AC component is returned to an initial value thereof, so as to extend the life of the image bearing member in situations where the exchangeable unit is exchanged and the AC component might otherwise have a magnitude inappropriate for the new unit.
