Abstract
A headrest device includes a stay member having a pair of vertical supporting bars adapted to be supported on a seat back of a vehicle seat and a horizontal supporting bar connecting the pair of vertical supporting bars, and a frame member having a connecting portion rotatably mounted on the horizontal supporting bar with a friction force existing between the horizontal supporting bar and the frame member. The frame member is provided with a slit extending along the connecting portion of the frame member and having ends extending towards the connecting portion. The portion of the frame defined by the slit can be resiliently deformed in the peripheral direction of the horizontal supporting bar and serve as a fulcrum point for adjusting the strength of the rotational friction force of the connecting portion.
