装置。[Claims for Utility Model Registration] (1) In a device in which a stay of a headrest is inserted into an insertion hole of a seat bag and this stay is locked to the seat bag, an elastically expandable C is attached to the upper end of the seat bag. A clamping spring having a letter-shaped clamping part and an operating body for expanding the clamping part of the clamping spring against its elastic force are provided, and a stay of the headrest is inserted into the inside of the clamping spring, and the stay is moved. A locking device for a headrest, characterized in that the headrest is elastically clamped by the clamping part, and the clamping is released by expanding the clamping part based on the operation of the operating body. (2) The locking device for a ret rest as set forth in claim 1, wherein the clamping spring has a friction member at least on the inner peripheral portion of the clamping portion.
