Claims

[Scope of utility model registration request]

The stay holder is provided with a stay holder that locks and holds the stay at a predetermined position in the longitudinal direction by inserting a headrest stay having multiple stages of stopper grooves, and this stay holder is attached to a holder bracket fixed to the side to which it is attached. It has a head that is exposed to the outside at one end of the body that is held in a rotatable state by being fitted into the head, and inside this head there is a peripheral edge of a through hole into which the stay is inserted. A cavity is formed in which a locking spring material having one end facing the stopper groove is loaded, and the other end of the locking spring material is held on the stay holder side within this cavity, The stay holder is configured so that by rotating the stay holder using its head as an external operation part, the engaging end of the locking spring material can be selectively exposed to the through hole into which the stay is inserted. Headrest support structure.
