ABSTRACT:
A structure for centering and connecting two members includes a first member having an engagement opening, and a second member having an engagement projection which has an outer peripheral surface substantially corresponding to an inner peripheral surface of the engagement opening. Small protrusions extend radially outwardly and are equidistantly disposed along a circumferential direction on the outer peripheral surface of the engagement projection. Straight notches are formed in the outer peripheral surface on both axial sides of each small protrusion to provide elasticity. When the engagement projection is fitted into the engagement opening, the small protrusions are elastically urged against the inner peripheral surface of the engagement opening. In this way, even when the two members have different thermal expansions, no play or no excessive stress is generated between the two members.
