The adaptor (20) has: a first recess (21T1) which is formed in the front face (21S1) thereof which faces the digging tooth (30); and an insertion section (22) which protrudes from the front face (21S1). The digging tooth (30) has: a first protrusion (31T1) which is formed on the back face (31S5) thereof which faces the front face (21S1) of the adaptor (20); an insertion hole (32) into which the insertion section (22) is inserted; and first and second shaft holes (36, 37) through which the retainer assembly (40) is inserted. The first protrusion (31T1) is inserted into the first recess (21T1). The back face (31S5) has a rectangular outer edge which consists of a pair of long sides and a pair of short sides. The first and second shaft holes (36, 37) are formed along the pair of long sides. The outer peripheral surface (Q1) of the first protrusion (31T1) is separated from the inner bottom surface (R1) and the inner side surfaces (R2) of the recess.
