In the case of a claw toothing for a gearbox or the like, of which the claws are designed with an undercut and, viewed in cross-section with respect to the longitudinal axis of the claws, have a flat or convex roof profile, it is provided to improve the engagement that the plan view of the claws tapers into a wedge shape towards the rotational axis of the claw toothing and that the generatrices (5a, 5b) of the roof profile and/or the sides, in the longitudinal direction of the claw, are straight lines which go through the rotational axis (D).
