ABSTRACT:
The present invention provides a tightening structure with which a reduction in processing steps is achieved without modifying the shape of a partner member an improvements in bolt strength and fatigue strength are achieved, and with which the fitting length of a thread ridge is not altered greatly in comparison with a conventional tightening structure such that a size reduction can be achieved, thereby contributing greatly to a reduction in the weight of a vehicle.
