A thrust plate assembly for a motor vehicle friction clutch includes a wear adjustment device arranged between the diaphragm spring and a component such as the housing or the pressure plate, and has at least one adjustment element which is displaceable and is pretensioned. At least one play sensor arrangement for detecting wear of the friction linings is clamped between the pressure plate and the flywheel. The play sensor arrangement includes a locking/detection element which is arranged on one component such as the housing or the pressure plate and which is pretensioned against the wear adjustment device with a locking portion and acts upon this wear adjustment device to prevent a movement of the at least one wear adjustment element and which interacts with another component for detection of wear. The latter component is displaceable with respect to the first component when wear occurs. The locking/detection element can be brought into a position for releasing the at least one adjustment element for movement in the wear adjusting direction when wear occurs by means of the interaction with the other component. Further, there is provided a stopping element by which the locking/detection element can be locked against movement of its pretensioning direction when the locking/detection element is brought into its position for releasing the at least one adjustment element.
