A working machine includes a load transmitting member including: an upper pillar part; an intermediate part extending to circumvent a window from a position above a lower corner of a window edge of the window and outer than the lower corner in a wall width direction to a position below the lower corner and inner than the lower corner in the wall width direction; and a beam part extending so as to be farther away from a wall side edge under the window. 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 a cabin is transmitted to an upper frame. At least the intermediate part of the load transmitting member is made of a single member.

Working machine

Provided is a compact and high-strength cab capable of securing an excellent field of view for work. The cab includes a guard protecting a cab body, and a wiper having a blade to wipe a front window member and a blade actuator for actuating the blade. The guard includes a pair of side pillars and an actuator housing beam interconnecting the side pillars and housing the blade actuator. The actuator housing beam includes a hollow beam body formed with a body opening and a front-rear partition plate partitioning the inside of the beam body into front and rear sections. The body opening allows the blade actuator to be assembled to the front-rear partition plate therethrough.
