Abstract
A bucket tooth assembly is mounted to an adapter provided to a distal end part of a bucket of construction equipment. The bucket assembly includes a bucket tooth and a latching member. The bucket tooth has a cavity for inserting the adapter and a through-hole that is provided to the side face and communicates through to the adapter when the bucket tooth has been mounted to the adapter. The through-hole has a center axis. The latching member is fitted inside the through-hole and having a rotational axis disposed along a direction of the center axis and a bottom part provided to an end on an adapter side in an axial direction. The latching member is rotated to switch between a first state in which the bottom part is held inside the through-hole and a second state in which the bottom part protrudes toward a concave portion on the adapter side.
