摘要：
A valve spring is used in a valve operating mechanism for moving a poppet valve up and down in an internal combustion engine of an automobile. The terminal end of the uppermost portion of the valve spring extends in a tangential direction to go away from an axis of the valve spring, thereby avoiding contact with a retainer to prevent wear.
