Abstract
A headrest device includes a thinner and improved positioning of the vertical position adjusting device. A geared or threaded drive shaft and a guide are positioned parallel to each other and parallel relative to a backrest. The driving force is directly transmitted from a motor unit positioned at the upper portion of the drive shaft and the guide to the drive shaft without a gear cable. The motor unit is directly assembled between a pair of longitudinal stay shaft portions at the upper portion of a seat backrest frame without a bracket.
