Claim 0:
1. A bucket for an excavator, the bucket comprising:
a bottom surface portion configured to form a floor of the bucket for the excavator, the bottom surface portion formed to be bent upward while extending in a rearward direction;
a first side surface portion coupled to a first side surface of the bottom surface portion;
a second side surface portion coupled to a second side surface of the bottom surface portion;
a main body rod disposed between the first side surface portion and the second side surface portion, the main body rod coupled to each of the first side surface portion and the second side surface portion;
a cover portion having one area coupled to the main body rod, the cover portion configured to form an upper surface of the bucket for the excavator;
a support portion having one area coupled to the main body rod and the other area coupled to the bottom surface portion;
a first coupling bracket coupled to the main body rod, the cover portion, and the support portion, the first coupling bracket formed to protrude in a direction toward an outside of the bucket for the excavator; and
a second coupling bracket formed at a position symmetrical to that of the first coupling bracket,
wherein each of the first coupling bracket and the second coupling bracket comprises a plurality of rod holes formed laterally therethrough, and each of a first coupling rod and a second coupling rod is coupled to the plurality of rod holes on both the first and second coupling brackets, and the first coupling rod and the second coupling rod are configured to be coupled to a bucket coupler,
wherein the cover portion and the support portion are formed in a shape of being bent at least once, and an inner cavity formed between the cover portion and the support portion is formed as a space having a quadrangular or polygonal shape in a cross-section view,
the cover portion comprises:
an upper extension portion having one side coupled to the main body rod, the upper extension portion formed to extend in the rearward direction and formed in a flat shape without a portion protruding upward extending in response to positions between the first and second coupling rods; and
a first rear surface portion formed in a shape of being bent from the upper extension portion, the first rear surface portion having one side coupled to the support portion,

the support portion comprises:
a rod coupling portion having one side coupled to the main body rod;
a lower extension portion formed in a shape of being bent from the rod coupling portion, the lower extension portion formed to extend in the rearward direction; and
a second rear surface portion formed in a shape of being bent from the lower extension portion, the second rear surface portion having one side coupled to the bottom surface portion, and a distance between the upper extension portion and the lower extension portion being closer toward the rearward direction.
