Abstract: A bucket tooth adapter for a bucket includes a mounting portion and a nose portion extending from the mounting portion. The mounting portion includes a first body portion and a wide portion. The wide portion is wider than the first body portion and is provided between the first body portion and the nose portion.

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.

Abstract: 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.

Abstract: A tooth attachment structure for a bucket includes a tooth, a pin member, and a lock member. The tooth includes a guide groove provided on an inner surface of the tooth and a pin hole provided in the guide groove. The pin member is disposed in the pin hole. The lock member is disposed in the guide groove. The lock member locks the pin member. The lock member engages the pin member by sliding toward the pin member.

Abstract: A tooth mounting structure for a bucket includes a tooth adapter and a tooth. The tooth adapter includes a mounting portion mounted to the bucket and a nose portion extending from the mounting portion. The tooth includes an internal space for inserting the nose portion. The nose portion includes a rectangular tip portion, a rectangular base end portion and an octagonal connecting portion. An inner surface of the tooth is formed along an outer surface of the nose portion.
