1. An excavating bucket for a construction machine comprising:
a bottom plate that curves in a C shape; a pair of left and right side plates that along with the bottom plate form a box structure having a bottom part and an opening, and that are attached so as to spread out toward the opening at a first angle with respect to a center line of the bottom plate in a width direction; a cutting edge that is attached to a distal end portion of the bottom plate on an excavation side, and that has inclined parts at the left and right ends that are inclined toward the bottom part at the first angle; a plurality of adapters that are fixed to a distal end side of the cutting edge, with a plurality of excavating tooth members being respectively attached to distal ends the adapters of; a pair of left and right corner adapters that are fixed to the inclined parts of the cutting edge, with a pair of excavating tooth members being respectively attached to distal ends of the left and right corner adapters, distal end positions of the left and right corner adapters being disposed on the same line as distal end positions of of the plurality of adapters, and each of the left and right corner adapters having a recess into which the side plates are respectively inserted; and joint portions where the left and right corner adapters are joined to only the cutting edge by continuous weld.
