Abstract: A bottom plate includes a first deepest portion at which a length from a first reference straight line to the bottom plate is maximum. The first reference straight line passes through a front end portion of a front lip and a position at which a rear end portion of the bottom plate is contiguous to each of side plates. The first deepest portion is located on a second reference straight line orthogonal to the first reference straight line. A side end portion of each of the side plates is provided with a recessed portion. The recessed portion includes a second deepest portion at which a length from the first reference straight line to the recessed portion is maximum. The second deepest portion is located on the second reference straight line or located close to the front lip with respect to the second reference straight line.

Abstract: The bucket includes a bottom plate including a first deepest portion, a bracket provided on a back surface of the bottom plate, and a front lip. The bottom plate includes a first inclined portion on a side where the bracket is attached. A first reference straight line is defined that passes through a pivot axis of a bucket and a tip end of the front lip. A second reference straight line is defined that is orthogonal to the first reference straight line and passes through the first deepest portion. An angle formed between the second reference straight line and the front lip is smaller than an angle formed between the second reference straight line and the first inclined portion. An intersection point between the first reference straight line and the second reference straight line is located close to the front lip on the first reference straight line.

The first reference straight line passes through a front end portion of a front lip and a position at which a rear end portion of the bottom plate is contiguous to each of side plates. The first deepest portion is located on a second reference straight line orthogonal to the first reference straight line.

The recessed portion includes a second deepest portion at which a length from the first reference straight line to the recessed portion is maximum. The second deepest portion is located on the second reference straight line or located close to the front lip with respect to the second reference straight line.

Abstract: A boom includes a body and a base end bracket. The body includes a straight section and a wide section. When viewed from above, a width of the straight section is substantially constant. When viewed from above, a width of the wide section increases toward the base end bracket. The straight section and the wide section are smoothly continuous to each other.

Abstract: The number of steps required for a welding operation of a work implement of a hydraulic excavator is reduced while the welding quality is improved. A boom includes a top plate, a left side plate joined to the top plate, and a boom foot bracket. The boom foot bracket includes an extending portion. The extending portion includes a portion that faces a side surface of the top plate.
