1. A working machine, comprising:
an upper frame supported on a lower traveling body; and
a cabin having a box shape defining an inner space therein, and supported by the upper frame, wherein
the cabin includes:
a plurality of walls enclosing the inner space respectively from front, rear, left, and right thereof;
a load transmitting member disposed along a specific wall which is one of the walls, and
a rear pillar extending downward from an upper end of the specific wall to a lower end of the specific wall,

the specific wall has:
a wall side edge serving as a side edge located at an end thereof in a wall width direction which is a width direction of the specific wall and extending in a lengthwise direction; and
a window edge in the specific wall, the window edge defining a window located at a more inward position than the wall side edge in the wall width direction,

the window edge has:
a lengthwise section extending in a direction along the wall side edge;
a lower section extending in a direction intersecting the direction in which the lengthwise section extends; and
a lower corner connecting the lengthwise section and the lower section with each other, and
the rear pillar extends downward from the upper end of the specific wall to the lower end of the specific wall along the wall side edge,

the load transmitting member includes:
an upper pillar part extending downward from an upper portion of the specific wall along the lengthwise section of the window edge at a more outward position than the lengthwise section in the wall width direction and along the rear pillar adjacent to the rear pillar;
an intermediate part extending to circumvent the window from a position above the lower corner and more outward than the lower corner in the wall width direction to a position spaced at a distance below the lower corner and more inward than the lower corner in the wall width direction; and
a beam part extending from the intermediate part so as to be farther away from the wall side edge under the window, and

the upper pillar part, the intermediate part, and the beam part are continuous in this order so that a load applied to an upper portion of the cabin in a direction along the specific wall is transmitted to the upper frame, and at least the intermediate part of the load transmitting member is made of a single member.
