To provide a tapered seat integrated bolt easily constructed to less generate stress in the bolt while suppressing a cost increase.
The tapered seat integrated bolt 10 comprises a screw stem portion 32, a bolt head portion 34, and a tapered seat 36. The tapered seat 36 has a slit 38 extending along the screw stem from a tapered small diameter side terminal position to the bolt head portion 34. The existence of the slit 38 in the tapered seat 36 permits a non-fastened portion of the screw stem portion 32 to substantially extend without increasing the total length of the taper seat integrated bolt 10. As a result, the non-fastened porion of the tapered seat integrated bolt 10 can be easily deformed and stress be less generated at the fastened end of the tapered seat integrated bolt 10 during the load of external force.
