PROBLEM TO BE SOLVED: To make a tooth member movable and adjustable in response to the installing pitch of bucket tooth members inside a socket for inserting tooth member with respect to a packer for bucket in a shovel machine. SOLUTION: A plurality of tooth member sockets (2) are provided in lateral length direction within a main body plate (1), the lateral width (w) in left-to- right direction inside the socket is formed larger than the lateral width (w') of a tooth member (3), the tooth member (3) is inserted in a manner movable along the lateral width direction of the socket; for coupling the socket (2) to the tooth member (3) after moving and adjusting, a laterally long coupling hole (8) suited to the maximum amount of moving of the tooth member is drilled to the socket, moreover, a coupling hole (8') for lock pin is drilled in the tooth member (3), also a vertical dividing body (9) is formed in lateral direction of the inner center of the socket (2), and a recessed striped groove (10) to be inserted to the bottom of tooth member (3) is formed in the configuration of the bucket excavation and leveling device in the shovel machine for civil engineering work.
