A boom for a working machine, the boom including a main body formed by connecting upper parts of a left and right pair of sidewall parts to each other through a top wall part, and connecting lower parts of the left and right side wall parts to each other through a bottom wall part, the boom being provided with a partition inside the main body and in a longitudinal middle of the main body. A hydraulic hose is inserted in a hole within the partition. The partition includes a lower plate part that is welded to the bottom wall part, as well as a vertical plate part that is raised from the lower plate part and welded to the sidewall parts. The hose hole is formed from the vertical plate part to the lower plate part via a bending part between the vertical plate part and the lower plate part.

A swivel frame for a swivel work machine includes a swivel base plate supported on a traveling machine body to be pivotable about a swivel axis and mounting an engine at a rear portion thereof, a support bracket provided at a front end of the swivel base plate for supporting an excavator, a partition wall provided on the swivel base plate for partitioning space forwardly of the engine in the fore/aft direction, and a pair of right and left vertical ribs provided on the swivel base plate for interconnecting the support bracket and the partition wall. The swivel base plate is divided into a rear plate portion on the rear side thereof and a front plate portion on the front side thereof, the rear plate portion being formed of a plate thinner than the front plate portion. The rear plate portion and the front plate portion are fixedly connected to each other in such in a manner that upper surfaces thereof are flush each other. A rear portion of the front plate portion projects more rearward than the partition wall. A pair of vertical walls are formed on and project from the rear plate portion. Front portions of the pair of vertical walls project more forward than the rear plate portion and are fixedly attached to the rear portion of the front plate portion and the partition wall.
