A spoke structure for a vehicle wheel, of the type having a mutually concentric wheel hub (M) and rim (C), comprises an elongated central portion (2; 2') with longitudinal end portions (3, 4; 3', 4'), first connecting means (5; 5') for the removable fixing of one end portion (3) to the wheel hub (M), second connecting means (6; 6') for the removable fixation of the other end portion (4; 4') to the rim, in which the central portion (2; 2') comprises a reinforcing core (9, 9') of metallic material, with which the first and second connecting means (5, 6; 5', 6') are rigidly associated, and an aerodynamically shaped external lining body (10; 10') of relatively rigid composite material, which is stably secured to the outer surface of the reinforcing core (9; 9'). The reinforcing core (9; 9') is made of a filament-like element (11; 11') with a substantially constant cross-section, which has sufficient mechanical strength to prevent the separation of two or more sections of said elongated central portion (2; 2') in the event of the breakage of the external lining body (10; 10') of composite material.
