Abstract
A bucket tooth for a construction vehicle includes a through-hole formed in a side wall part and passing through to a cavity. The through-hole has on a cavity side a rotating body hole having a shape of a truncated and rotated cone that remains after removing a large diameter side portion obtained by cutting diagonally to a rotational axis of the truncated and rotated cone with a large diameter side of the truncated and rotated cone being disposed on the cavity side, and with the rotational axis of the truncated and rotated cone being inclined outwardly toward the distal end portion of the bucket tooth from the cavity along a width direction of the bucket tooth.
