PURPOSE: To provide centering installation structure between members in which play and excessive contact stress may not be generated even though members whose amounts in thermal expansion are different are mutually connected, centering between members can be facilitated, and which is simple in its structure and is easily manufactured. CONSTITUTION: This structure is equipped with a first member l having an engagement hole 11 and a second member 2 whose outer circumferential surface is formed in approximately the same as an inner circumferential surface of the engagement hole 11 and whose size is formed a little bit smaller than the engagement hole 11, and which has engagement projected parts 23 whose inner part are caved. Respective four small projections 25 projected toward a radial outside on an outer circumferential surface of the engagement projected parts 23 are circumferentially arranged in two parts at equal intervals. Linear notches 27 are arranged on both axial sides of the parts in which the small projections 25 of the engagement projected parts 23 are arranged so that elasticity can be applied to the parts in which the small projections 25 of the engagement projected parts 23 are arranged. The engagement projected parts 23 are fitted into the engagement hole 11 so that the small projections 25 are elastically brought in contact with the inner circumferential surface of the engagement hole 11. Centering between both members l, 2 can be carried out by this fit so that they are fixed. |
