Abstract

A bottom surface part (32) of a bucket (9) includes a first curved surface part (41) and a second curved surface part (42). The second curved surface part (42) is positioned closer to a back surface part than the first curved surface part (41) and is connected to the first curved surface part (41). A second curvature radius (R2) of the second curved surface part (42) is shorter than a first curvature radius (Rl) of the first curved surface part (41). The center (01) of the curvature radius of the first curved surface part (41) is positioned to the outside of a main bucket body (21) when viewed from the side. In a horizontal state where an imaginary line (S1) is arranged horizontally and the bottom surface part (32) is positioned below the imaginary line (S1), the first curved surface part (41) is arranged along a reference curved surface (S2) or above the reference curved surface (S2) when viewed from the side. A connecting part (P2) between the first curved surface part (41) and the second curved surface part (42) is positioned more towards a lip part (35) than the portion (P3) of the bottom surface part (32) that is positioned lowest in the bottom surface part (32) in the horizontal state when viewed from the side.
