Claims

[Scope of utility model registration request]

A head rest stay provided upright on the upper end side of the seat bag, a head rest main body having a guide portion into which the head rest stay is fitted and supported so as to be movable up and down on the head rest stay, the head rest main body is supported on the headrest stay in a state in which one side in the width direction serves as a rotation fulcrum and the other side is movable in the longitudinal direction of the seat. A plurality of stopper grooves are cut out in the vertical direction, and an engaging part that selectively engages with each of these stopper grooves is provided in the guide part, and this engaging part is normally connected to any stopper groove. 1. A headrest structure comprising a biasing means for biasing a headrest body so as to engage the headrest body.
