摘要： The present disclosure relates to a tooth (1) for attachment to the lip of a bucket of a working machine, such as an excavator or loader, via an adaptor, the tooth (1) comprising a cavity (103) for receiving a portion of said adaptor, the cavity (103) extending between said first and second opposed outer working surfaces (12, 14) from an open end (104), at said attachment end of the tooth, to a bottom end (105); the cavity (103) being delimited by an inner wall (102); said inner wall (102) comprising first and second internally facing inner walls (106, 107), being the internal surfaces associated with said first outer working surface and said second working outer surface (12,14), respectively, and opposing side walls (108), interconnecting said first and second inner walls (106, 107), the cavity defining a back portion (BP) extending along the Y axis, the back portion being at least partially located between the plane spanned by the X and Z axis and the open end (104) of the cavity, a front portion (FP) extending along the Y axis, the front portion being located between the plane spanned by the X and Z axes and the bottom end (105) of the cavity; and a stepped portion (SP), interconnecting the back portion and the front portion; in the back portion, the first and second inner walls (106, 107), each comprises a pair of essentially planar back contact surfaces (130a, b; 140a,b), being separated by a back divider region (132, 142), extending beyond the pair of first contact surfaces. The disclosure also relates to an adaptor, and to the coupling between a tooth and an adaptor.
