Claims

[Scope of utility model registration request]

A held part of the tilling claw is fitted into a holder hole of a claw holder protruding from the tilling shaft, and the claw holder and the held part are fitted so as to be relatively rotatable within a predetermined range with respect to the rotational direction of the tilling shaft. A narrow part is provided in the middle part in the rotational direction of the fitting part between the claw holder and the held part, and the held part is locally pinched by the claw holder by the relative rotation of the held part when the tilling shaft is rotated. 1. A means for supporting a tiller claw, characterized in that it comprises a supporting part with a clamping pressure.
