Abstract
In the head rest apparatus, a core member is separately formed from a metal plate and a metal stay, wherein a fixing member is integrally formed on a first divided body of the core member and the fixing member mechanically engages the flat plate portion of the metal plate with the first divided body and fixes the flat plate portion to the first divided body. The flat plate position is tightly fixed to the first divided body. Since the stress can be absorbed only by the first divided body, generation of abnormal noise can be prevented without using any damper member and in addition, rattling in operation can be prevented as well.
