PURPOSE:To secure safety of an assistant, by making a main step for an operator distinguishable from an auxiliary step for an assistant. CONSTITUTION:When an operator changes direction or temporarily stops operation, the operator steps on running clutch pedals 32 or a main clutch pedal 38. In the operation, since there is fixed distance between auxiliary steps 34 for an assistant and main steps 31 at left and right and difference in level between the auxiliary steps and the main steps so that the auxiliary steps are distinguishable from the main steps, the foot of the assistant is not unexpectedly sandwiched in the gap between the pedals and the steps.
