RIPPER POINT ATTACHMENT STRUCTURE AND RIPPER POINT
A ripper point attachment structure in a ripper device includes a ripper shank including a main body portion and a nose portion, and a ripper point including an internal space. The nose portion includes a distal end portion, a proximal end portion contiguous with the main body portion, and a linking portion. An outer periphery of a cross section cutting the linking portion along a plane perpendicular to an axis extending in a lengthwise direction of the nose portion is formed in an octagonal shape. An outer periphery of a cross section cutting the proximal end portion along the plane is formed in a rectangular shape. An outer periphery of a cross section cutting the distal end portion along the plane is formed in a rectangular shape. An inner periphery forming the internal space is formed along an outer periphery forming the distal end, linking and proximal end portions.
