<P>PROBLEM TO BE SOLVED: To provide a load-bearing ring which can be removed and split for releasing a fastening force of a system. <P>SOLUTION: Opposed faces are constituted to be mutually approached toward the inside with an inclination to be in tapered configuration in a cross-sectional view to opposed faces (225, 226) of a load-bearing ring (220) engaged with a complementary face of a receiving component. A taper angle between the opposed faces is selected to be a best angle for holding the load-bearing ring at a fixed position by sticking friction between the load-bearing ring and a contact face of the component in a loaded state, while facilitating removal of the load-bearing ring. The load is applied in parallel with a longitudinal axial line of a shaft mounted with the load-bearing ring. In a disposable load-bearing ring, adjacent segments (221, 222) are mutually connected by a predetermined weak part or a fragile part (228) which is broken when the load is released by shifting the position of the segments to the outside. <P>COPYRIGHT: (C)2013,JPO&INPIT |
