Summary:PROBLEM TO BE SOLVED: To prevent the detachment of adjacent tooth members to enhance soil working efficiency and work safety by fixing a plurality of adaptors in a parallel state to the excavating edge part of a bucket of a shovel type excavator, overlapping a front side stepped recess of the tooth member and a rear side stepped recess of the adjacent tooth member, and mounting each tooth member to each adaptor in the mutually overlapping state of the plurality of tooth members. SOLUTION: The tooth member 3 is detachably and protrusively provided at the excavating edge part 1a of the bucket 1 for the shovel type excavator through the adaptor 2. The front side stepped recess 5 is formed on a laterally one-side part front face of the tooth member, and the rear side stepped recess 6 is formed on the laterally other-side part rear face of the tooth member. The front side stepped recess and rear side stepped recess of the adjacent tooth members are formed to overlap with each other, and a slip-off stop guide mechanism 7 fittable to guide in a lateral direction is provided for preventing the detachment of the tooth member.
