A pressure plate assembly for a friction clutch comprises a housing arrangement, a pressure plate connected to the housing arrangement for rotation about an axis (A), a force-exerting arrangement, which is or may be supported relative to the pressure plate and the housing arrangement, and a wear take-up arrangement in the support path between the force-exerting arrangement and the housing arrangement. The wear take-up arrangement includes at least one adjusting element which may be displaced to compensate for wear, by means of which the force-exerting arrangement is or may be supported relative to the housing arrangement, a wear detection arrangement, mounted on the housing arrangement, which co-operates with the force-exerting arrangement in a wear detection area and which may shift, in the case of wear, relative to the housing arrangement, by means of the force-exerting arrangement. The wear detection arrangement has a take-up distance limiting area which co-operates with the at least one adjustable element to limit the take-up distance and further has at least one blocking element, which stops the return movement of the wear detection arrangement after the shift relative to the housing arrangement, as a result of wear-induced displacement of the wear detection arrangement.
