(54) Fan rotor


(57) A fan in plastic material of motor-driven fan for a motor vehicle cockpit comprising: a first cap-shaped portion (10), integral to a rotor (26) of an electric motor and provided with centred holes (8) for the passage of the shaft of the motor around which rotates the cap itself; a second portion in the shape of a fan wheel (11) which is integrally in rotation with the cap (10), and provided with a series of bladings (17) which are equally orientated and angularly distanced from each other on a circumferential extension; the fan is characterised by the fact that the cap (10) and the fan wheel (11) are two distinct elements provided with respective unmatchable snap coupling means (13, 23) to render them integral in rotation as a single body.
