Abstract
With a ripper point attachment structure, a pin member is inserted into a first pin hole formed in a ripper shank and a second pin hole formed in a ripper point. A locking member is engaged with the pin member to prevent the pin member from coming loose. The ripper point includes an opening, an internal space and a guide groove. The opening is formed at a rear end. The internal space is formed from the opening toward a distal end surface. The guide groove is formed in a predetermined range from the rear end toward the distal end surface in a portion of an inner surface forming the internal space. A second pin hole of the ripper point is disposed on a bottom surface of the guide groove. The locking member is disposed in a space forming the guide groove.
