Abstract
Perfected crankshaft for toys tricycles, essentially characterized by having, in the central area of the crankshaft, on which the wheel itself is cast, radial elements with a concave-convex surface, with transverse passages to be occupied by the molding mass of the wheel to which they arm and in solidarity with the crankshaft, preventing this autonomous movement.
