Abstract
A rocking bearing is proposed which is low in cost. A raceway is formed on the inner periphery of an arcuate bearing ring. Rolling elements are received in pockets of a retainer provided opposite to the raceway. The bearing ring is formed by pressing a steel plate to reduce the cost and achieve light weight and compactness.
