Abstract
A forward and backward inclination adjustment device for a headrest provided with a headrest body frame section and a generally inverted-U-shaped frame having a horizontal columnar frame section and a pair of headrest stay portions. In the forward and backward inclination adjustment device, a leaf spring element of generally “U” shape is fixed to the headrest body frame, while embarcingly holding the horizontal columnar frame section, and a plurality of discrete flat surfaces are formed in the circumferential surface of the horizontal columnar frame section. Thus, each time a user inclines the headrest body frame section forwardly and backwardly relative to the headrest stay portions, the leaf spring element is contacted with one of the discrete flat surfaces, thereby imparting a clicking stepwise touch to a hand of the user.
