Claims

[Scope of Claim for Utility Model Registration] A tilling claw attachment device that inserts the attachment base of the tillage claw into a bracket provided on the tillage shaft and has a retaining pin that penetrates through the bracket and the attachment base to prevent both from coming out, and a fitting recess with a V-shaped cross section that fits into each other along the length direction is formed on the side surface of the mounting base, and a pin insertion part for inserting the retaining pin in the middle of the fitting recess. A hole is provided in the pin insertion hole, which is provided on the tip side of the pin, and is elastically deformed in the axial direction of the pin so that it can pass through the pin insertion hole, and has a function to prevent the pin from coming out when it is inserted into the pin insertion hole. A tilling claw attachment device characterized in that a retaining pin having a spring member that can be inserted and removed is provided.
