Mounting structure for rolling bearing

摘要

A rolling bearing mounting structure for mounting a rolling bearing to an insertion bore (25) formed in a support member, provided with: an anti-slip piece (26) arranged on an axial end portion of the insertion bore formed in the support member, and preventing the rolling bearing from slipping out of the insertion bore toward one of one side and the other side of the insertion bore in a direction of the axial center; a first concave section (27) formed at a position halfway along the insertion bore (25) in the direction of the axial center, in a circumferential direction; a second concave section (28) formed at a position opposed to the first concave section (27) in a diameter direction on an outer peripheral surface of the outer ring member provided at the rolling bearing, in the circumferential direction; and an anti-slip member (30) engaged with engagement surfaces formed on the first concave section and the second concave section, respectively, and preventing the rolling bearing from slipping out of the insertion bore toward the other one of one side and the other side of the support member in the direction of the axial center.
