Document Type and Number:
WIPO Patent Application WO/2011/049061
Kind Code:
A1
Abstract:
A bottom surface section (32) of the bucket (9) has a first curved surface section (41) and a second curved surface section (42). The second curved surface section (42) is located nearer the back side than is the first curved surface section (41), and is connected to the first curved surface section (41). A second radius of curvature (R2) of the second curved surface section (42) is smaller than a first radius of curvature (R1) of the first curved surface section (41). From a side view, the center of radius of curvature (O1) of the first curved surface section (41) is located outside a bucket body (21). Furthermore, from the side view, the first curved surface section (41) is disposed along a reference curved surface (S2) or above the reference curved surface (S2) in a horizontal state where a phantom line (S1) is disposed horizontally and where the bottom surface section (32) is positioned below the phantom line (S1). Moreover, from the side view, a connection section (P2) between the first curved surface section (41) and the second curved surface section (42) is located, in a horizontal state, nearer a lip section (35) than is that portion (P3) of the bottom surface section (32) which is located at the lowest position.
