ABSTRACT:
Interfitting apparatus including a fitting jig formed with a plurality of regulating openings each for receiving therein one of a plurality of shaft members having chamfered forward ends, which are objects of interest, to hold the shaft members by regulating their posture and allow them to move freely within tight tolerances, and a table at least slightly movable in a horizontal direction for supporting, by precision positioning, an object formed with a plurality of holes separated from one another by a spacing substantially the same as the spacing between the regulating openings of the fitting jig. In fitting the shaft members in the respective holes in the object, the fitting jig is moved in a vertical direction toward the table, and guiding members and guided members mounted in the fitting jig and the table respectively are brought into engagement with each other so that the former may guide the latter, to thereby allow the table to move slightly in the horizontal direction to effect positioning of the shaft members and the object horizontally relative to each other within the range of the chamfers. Thereafter the fitting jig is further moved in the vertical direction to interfit the shaft members and the holes in the object with each other by exerting a fitting force on the shaft members from outside a jamming area.
