Abstract

A tooth block (2) to be attached to a bucket (1) for a shovel machine, wherein the tooth block (2) is removably attached to the bucket (1) through an adapter member (3) provided at the lip of the bucket and projecting therefrom. The tooth block (2) is provided with a masking portion (4) for masking the gap produced between the lip of the bucket (1) and the base of the tooth block (2) when the tooth block (2) is attached to the lip of the bucket (1). The masking portion (4) is provided outside the base of the tooth block (2) such that the masking portion (4) is overlapped with the outer surface of the lip of the bucket (1), and is connected and fixed to the bucket (1) through a fixing portion (5).
