<p>PROBLEM TO BE SOLVED: To simply and inexpensively obtain a bearing structure of which smooth rotation is not impaired even if a run off to prevent burr generating in the forming process from protruding is formed. SOLUTION: In the bearing structure provided with a turning shaft having a pair of large diametral flanges with different axial directions from each other and a small diametral part positioned between the pair of large diametral flanges, and a bearing member having a turning support groove in which the small diametral part of the turning shaft is retractably fitted from the orthogonally crossing direction with the axial direction and a pair of positional regulation faces in contact with the opposite end face of the pair of large diametral flanges of the turning shaft supported in the turning support groove, a pair of conical taper receiving faces corresponding to the taper outer peripheral face of the pair of large diametral flanges of the turning shaft are provided from the positional regulation face toward the turning support groove. A run off face coming into noncontact with the taper receiving face of the bearing member is formed at a circumferential part of the taper outer peripheral face of the turning shaft.</p> |
