Provided is a headrest locking device capable of appropriately locking the vertical movement of a headrest body. A headrest lock device (3A) is provided with a headrest strut (strut) (20) and a lock mechanism (30) which is provided to a headrest body (10) supported by the strut (20) and locks the vertical movement of the headrest body (10) by engaging with a cutout groove (23) of the strut (20). The lock mechanism (30) has: a lock plate (31) that engages with or disengages from the cutout groove (23) by movement in the width direction; and a lock spring (32) that urges the lock plate (31) in the direction in which the lock plate (31) engages with the cutout groove (23). The lock plate (31) and the cutout groove (23) have mating surfaces (31A, 23A) which are in planar contact with each other at an angle inclined with respect to the urging direction of the lock spring (32).
