Abstract: The invention concerns an output element (15; 151) for a motorisation device (1) for driving at least one windscreen wiper arm of a motor vehicle, comprising an output shaft (17; 171) and a toothed wheel (40) integral to and coaxial with the output shaft (17; 171), characterized in that the output shaft (17; 171) is made of plastic material and in that the output element (15; 151) comprises a metallic insert (16; 161; 162; 163), the plastic material of the output shaft (17; 171) being moulded partially over the metallic insert (16; 161; 162; 163), revealing an insert head (25; 251) protruding from the end of the output shaft (17; 171) and intended to connect to a windscreen wiper element in order to drive this in rotation. The invention also concerns a motorisation device (1) and a method for production of an output element (15; 151).

Abstract: The invention relates to a toothed wheel comprising a central bore which defines a central rotation axle and a secondary bore in which a crankpin is fixed. The invention is characterized in that one of the faces thereof is equipped with means for determining the distance between the central axle of the central bore and the axle of the crankpin in the secondary bore, the means taking the form of coding means.
