A headrest for a vehicle seat has a base member attached to a seatback of the vehicle seat, a body frame attached to the base member so as to be capable of tilting, a locking device for locking the body frame with the base member so as not to be capable of tilting, and an unlocking device for unlocking the locking device. The unlocking device includes a swinging body attached to the base member so as to be capable of swinging and a moving body attached to the body frame so as to be capable of moving with respect thereto. The moving body moves with respect to the body frame by being pushed by the swinging body to unlock the locking device. The swinging body has a connecting portion to which one end of a cable is connected and an arcuate-shaped outer peripheral surface on which the cable is disposed. And the cable is retracted into a tubular portion provided on the base member from an entrance of the tubular portion when the cable is pulled to unlock the locking device. The entrance of the tubular portion is located substantially on a tangent line of the arc of the outer peripheral surface.
