PROBLEM TO BE SOLVED: To provide a support structure of a propeller shaft capable of preventing decrease of a bolt axial force on fastening a mounting bolt. SOLUTION: A vibration isolation mechanism of the support structure consists of a collar 6 fit to an outer circumference side of the mounting bolt 3 and mounted to a lower surface side of a cross member by the bolt and a nut 4, a pair of upper and lower rubber bushes 7, 8, fit and held by an outer circumference surface of the collar, for supporting an end part of a bracket in a clipping state, a washer 5 provided between a lower end surface of the collar and a seat surface of the bolt and an annular sheet member 9 adhered to an end surface at the seat surface side of the bolt of one of the rubber bushes by vulcanization and fit with an outer circumference surface of an end part of the collar. The lower end surface 6d contacting with the washer is formed to protrude from a lower surface at an opposite side of the rubber bush of the seat member and a fine clearance C is formed between an upper surface of the washer and the lower surface of the seat member when fastening the bolt.
