To provide a simple embodiment of a rotor (2) for a fluid pump which is nevertheless very flexible in handling and compressible, in accordance with the invention a conveying blade is provided having at least two arms (12, 13, 14) and a membrane spanned between them hi the expanded state, wherein the struts each have at least one joint, in particular more than one joint, which enables an angling in a first direction in a first movement and bounds an overelongation beyond an elongation angle of in particular 180 in the opposite second direction. In particular when a plurality of joints (15, 16, 17) are provided at the struts, they, and with them the conveying blades, are particularly flexible for simple compressibility.
