A component assembly for a motor vehicle includes a housing and an actuating element that is rotatable about an axis. The assembly also includes an actuator which is configured to cause a rotation of the actuating element. The assembly further includes a rotatable shaft which extends along a shaft axis and is disposed between the actuating element and the actuator and which is coupled to the actuating element and the actuator. The shaft is guided through a first through opening in the housing. A sealing system is provided in a radial direction perpendicular to the shaft axis so as to be between the shaft and a first internal wall of the first through opening. The sealing system has a sealing element support having a first side and a second side that faces away from the first side. The sealing element support is fastened in the first through opening. The sealing element support has a second through opening having a second internal wall. The shaft is guided through the second through opening. A first sealing element is fastened in a locationally fixed manner to the sealing element support on the first side of the sealing element support. The first sealing element has a third through opening through which the shaft is guided. The first sealing element by way of a third internal wall of the third through opening bears in an encircling manner on the shaft. And the first sealing element is designed from felt.

An object of the present invention is to hold a holding member appropriately in a casing. A rotary electric machine includes a rotor having a drive shaft, a stator provided on an outer periphery of the rotor, a bearing B2 that rotatably supports the drive shaft, a holding member that contains an aluminum alloy member and holds the bearing, and a casing that houses the rotor, the stator, the bearing, and the holding member. The casing is made of a member that does not grow permanently or an aluminum alloy member that is permanently grown when the holding member is fixed to the casing. The holding member is in a state before permanent growth before being fixed in the casing, and the holding member grows permanently to be fixed more firmly to the casing.

An integrated magnetic shield and bearing holder useable with electric motors includes a shaft portion and a cover portion extending radially outward from the shaft portion. The shaft portion includes an inner wall defining a channel and a ledge extending radially inward from the inner wall. The cover portion includes a first layer, a second layer extending substantially parallel to the first layer, a magnetic shield extending between the first layer and the second layer, and an outer wall extending from the first layer and/or the second layer such that a space is defined between the outer wall and the shaft portion. The cover portion includes one or more retainers coupled to the magnetic shield to restrict movement of the magnetic shield relative to the first layer and/or the second layer.
