Abstract
It is an object of the present invention to provide an improved technique of joining a first body part and a second body part of a sun visor body to manufacture a sun visor for vehicles. The representative A sun visor for vehicles comprises a sun visor body, a first and a second body parts to from the sun visor body, a first weld region, a second weld region. The first weld region includes a first weld formed on the first body part and a first weld formed on the second body part. The second weld region includes a second weld formed on the first body part and a second weld formed on the second body part. The first welds formed respectively on the first and second body parts contact each other and are joined together by vibration before the second welds formed respectively on the first and second body parts contact each other. After that, the second welds contact each other and are welded together by vibration as the first welds are welded together by vibration and at this time, the first welds receive a welding pressure that acts between the first and second body parts, thereby controlling a welding pressure that acts upon the second welds during vibration welding.
