PROBLEM TO BE SOLVED: To provide a reamer bolt connecting structure of a marine propeller shaft, which facilitates a press-fitting operation and a picking-up operation, and prevents the seizure of the surface in order to connect a matter to be connected in a marine propeller shaft etc.SOLUTION: In the reamer bolt connecting structure 1 of the marine propeller shaft, two connecting flanges 102, 106 are connected with each other. The connecting flanges 102, 106 have a bolt hole 10 having a reamer part 22 of the reamer bolt 20 and a predetermined fastening margin. The bolt hole 10 has a hole release part 11 for expanding the diameter so as to have an outer surface of the reamer part 22 of the reamer bolt 20 and a predetermined gap 31 at an insertion starting end of the reamer bolt 20. The reamer bolt 20 has a bolt releasing part 21 contracting in the diameter so as to provide with a predetermined gap 30 with the inner surface of the bolt hole 10 at the insertion terminating end of the reamer part 22. |
