Abstract

PURPOSE: To reduce wear of rolling bodies, by forming the diameter of each edge part of a pocket of each retainer of a bearing into such a shape that when the retainers are moved in the axial direction they can evade the contact with the rolling bodies, and by engaging end surfaces of each retainer with opposite surfaces of track wheels acting as receiving part.
CONSTITUTION: A movable bearing of a movable blade variable type axial flow fan which accommodates the axial force comprises an inner track wheel 7, an outer track wheel 8, ball-shaped rolling bodies and retainers 10. The retainer 10 has a pocket 10a in the shape of a cylindrical bore, and end surfaces 10c of the retainer 10 abut against opposite inner surfaces of respective track wheels 7, 8 that can act as the receiving part when the retainer 10 is moved in the axial direction. The diameter of each edge part 10b of the pocket 10a is formed such that the retainer 10 can evade the contact with the rolling body 9 when the retainer 10 is moved in the axial direction. Thus when the retainers 10 are moved in the axial directions, the edge part 10b wolud not contact the rolling bodies 9 and therefore the wear of the rolling bodies 9 is reduced.
