Abstract (en)
A slip mechanism for use in a timepiece comprising a shaft member (20, 20-a, 20-b) made of metallic material; a pinion (22) which is fixed to a first portion (20-b) of the shaft member (20, 20-a, 20-b); and a toothed wheel (21) made of synthetic resin material, the toothed wheel (21) being drivingly connected to a second portion (20-a) of the shaft member (20, 20-a, 20-b) so as to permit rotation of the toothed wheel (21) to be transmitted therefrom to the shaft member (20, 20-a, 20-b) and also to permit slip to occur therebetween characterised in that the pinion (22) is made of synthetic resin material and that the second portion (20-a) of the shaft member (20, 20-a, 20-b) is an integral portion thereof which frictionally engages the toothed wheel (21).
