PROBLEM TO BE SOLVED: To provide a structure for preventing threads from being rolled-in on a shaft of a vehicle such as a fork lift. SOLUTION: The structure 10 is provided with a protector 14 comprising a pair of plate-like semi-circular members 12. In the protector 14, the pair of semi-circular members 12 are abutted on each other in the state that a clearance 18 is provided between respective ends 16 of the pair of semi-circular members 12. The protector 14 blocks arrival of the threads to the shaft. Even if the threads arrive at the shaft, a cutter is intruded into the clearance 18 and the threads can be cut/removed.
