Abstract: A bucket with a blade-shaped lower front edge includes: a first straight portion horizontally extending from the lower front edge toward an innermost of the bucket; a curve continuous with a rear edge of the first straight portion at a lower edge of the curve, the curve having a predetermined bucket radius; a second straight portion continuous with an upper edge of the curve, the second straight portion being inclined upward toward a bucket opening; a third straight portion bent at a bent portion toward the bucket opening relative to a front edge of the second straight portion, the third straight portion further extending toward the bucket opening; a reinforcing member provided on an exterior surface of the third straight portion to reinforce of the exterior surface; and a connecting portion provided behind the curve.
