A variable geometry turbine (1) comprises: a housing (4); a turbine wheel (6); a movable wall member (12); a cavity (25) provided in the housing and an inlet passageway (11) extending radially inwards towards the turbine wheel. The movable wall member comprises a generally annular wall (20) and radially inner and outer flanges (21, 22) extending axially from the generally annular wall, inner surfaces of the generally annular wall and radially inner and outer flanges defining an interior surface of the movable wall member. The cavity is suitable for receipt of the radially inner and outer flanges of the movable member, the movable wall member being axially movable relative to the housing. The cavity is defined by radially inner and outer curved side surfaces (26, 27) and a base surface (28) generally matching a profile shape of the interior surface of the movable wall member.
