A digging tooth mounting assembly has an adapter, a digging tooth and a retainer assembly. The adapter includes a front surface facing the digging tooth, a recess formed on the front surface, an inserted part projecting from the front surface, and a insertion through hole formed in the inserted part for receiving the retainer assembly. The digging tooth includes a rear surface facing the front surface of the adapter, a projecting part formed on the rear surface for insertion into the recess, an insertion hole formed on the rear surface for receiving the inserted part, and a pair of shaft bores for receiving the retainer assembly. An outer peripheral surface of the projecting part is spaced apart from an inner bottom surface and an inner side surface of the recess. |
