ABSTRACT:
A bucket tooth capable of preventing a bolt from being loosened during operation is provided. In order to allow the bucket tooth to generate a resilient return force after attachment, a warp is caused by resilient deformation so that a face on the bucket lip side becomes a concave face. As another means, a spot facing portion is formed around a bolt hole into which a fastening bolt is inserted, on the side facing the bucket lip.
