A cabin structure for a working machine includes a substantially transparent cabin element equipped with a bottom part having a seat for the operator of the working machine, a display and a controller for controlling the operations of the working machine. The cabin structure also includes a control mechanism for tilting the cabin element in relation to the frame of the working machine in both XZ and YZ directions. The cabin element is arranged to be substantially stationary in relation to the frame of the working machine, and the seat and controller are placed on a working base placed above the bottom part of the cabin element. The control mechanism is pieced positioned between the working base and the bottom part of the cabin element. The control mechanism can also rotate the working base around the Z axis.
