PURPOSE:To hold down the change of the driving position of an operator and consequently improve the operability by a structure wherein holding parts, which restrain the shift of a top panel by abutting the inner surfaces of side walls against spill guards when the top panel vibrates, are formed. CONSTITUTION:A spill guard 20 consists of a main body 22 formed by folding a flat sheet and round bars 26 and 27, which are fixed at the front end 24 and rear end 25 of the main body 22 in the vertical direction of a car body 10 so as to serve as a holding part. When a top panel 30, which is formed out of FRP or the like for saving weight, is employed, even though the panel 30 is given enough strength to the vertical load of an operator, the panel 30 sometimes vibrates sidewise during running. When said vibration occurs, the vibration of the top panel 30 is immediately restricted by the abutment of the round bar 26 against the bead part 38. As a result, the driving position of an operator is controlled at a constant position at all times and favorable operability is obtained. |
