Construction-equipment bucket-tooth assembly and bucket provided to same

A bucket tooth assembly that is interchangeably mounted to an adapter provided to a distal end part of a bucket of a construction equipment, the bucket assembly comprising:

• a bucket tooth having a cavity for inserting the adapter, a contact face inside the cavity that comes into contact with an outer face of the adapter so as to receive a load exerted during work, a side face having a triangular shape on an outer face of the bucket tooth, 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 having a center axis;
• and
• a latching member 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 a side of the adapter in an axial direction, the latching member being rotated around the rotational axis 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 side of the adapter,
• the latching member being arranged such that a length of a side face portion is in left and right asymmetry in a cross sectional view along the rotational axis.
