PROBLEM TO BE SOLVED: To provide a bolt fastening structure for a vehicle that can make compatible a high antitheft effect and sufficient workability at vehicle maintenance or the like.SOLUTION: Since a turning angle of a loosening tool 50 is limited when loosening a fastening bolt 16 by using a loosening tool 50, a high antitheft effect for preventing a bracket 12 from being illegally removed from a transmission case 14 is secured. Since work for loosening the fastening bolt 16 is progressed by making the loosening tool 50 engaged with a polygonal part 22, the sufficient workability at the vehicle maintenance or the like is also secured. The whirl stop of a protector member 38 with respect to the bracket 12 is achieved by inserting a leg 32b of a washer 32 into an insertion hole 47a of the protecting member 38 and an insertion hole 47b of the bracket 12, there is no necessity for welding the protector member 38 to the bracket 12, and manufacturing costs can be reduced. |
