Abstract
A spring for sun visors includes a torque application section that extends from a holding section and applies torque when a main section is rotating. The holding section has a flat section that receives torque from a shaft. The torque application section has a first spring piece extending from one end of the holding section and a second spring piece extending from the other end of the holding section and being bent so as to fold back. The first spring piece has a first tip section that includes overhanging sections that are narrower than the width of the holding section. The second spring piece has a second tip section that is arranged so as to overlap on the outside of the overhanging sections. The overhanging sections are provided in an area extending from the torque receiving section to the first tip section.
