An outer periphery of a cross section cut out from a joint part 33 in a plane orthogonal to an axis A1 extending in a longitudinal direction of the nose part 22 is formed into an octagonal shape. An outer periphery of a cross section cut out from a base part 32 in a plane is formed into a rectangular shape. An outer periphery of a cross section cut out from a tip part 31 in a plane is formed into a rectangular shape. An inner surface forming the inner space S of the ripper point 12 is formed along an outer surface forming the tip part 31, the joint part 33, and the base end part 32 of the nose part 22.SELECTED DRAWING: Figure 7
