The present invention relates to a silicone liner for the will, and specifically, the main body 10 including the upper part 11 and the lower part 12 into which the cut part of the body is inserted, and the outer surface formed on the outer surface of the main body 10. Adapter 20 which is combined with the end portion 30 formed at the lower end of the skin 20, the outer skin portion 20, and one end is coupled to the end portion 30 and the other end is connected to the socket 5 of the will (3) A willing silicone liner comprising 40, wherein the adapter 40 comprises: a connecting shaft 41; A first blade part 42 formed along an upper outer circumferential surface of the connecting shaft 41; And a second blade portion 43 spaced apart from the first blade portion 42 of the connecting shaft 41 by a predetermined distance, and formed along an outer circumferential surface of the connecting shaft 41. The first wing portion 42 is formed with a silicon inlet groove 42a along an outer circumferential surface, the second wing portion 43 has a visible portion 43a formed on an upper surface thereof, and the adapter 40 includes: Structural impact by selecting from a combination of engineering plastics including Thermoplastic Elastomer (TPE), Thermoplastic PolyUrethane (TPU), and ThermoPlastic Vulcanizate (TPV). Absorption function facilitates blood circulation of the body contact surface even when walking for a long time, thereby reducing fatigue, and the life of the silicone liner can be prolonged because the adapter does not fall off from the end even in long-term use. In addition to forming a silicon inlet groove in the wing portion to maintain the flowability of the silicon in the manufacturing of the silicone liner for will, relates to a silicone liner for will to improve its productivity.본 고안은 의지용 실리콘 라이너에 관한 것으로, 구체적으로는 신체의 절단부위가 삽입되는 상부(11) 및 하부(12)로 이루어지는 본체(10)와, 상기 본체(10)의 외표면에 형성되는 외피부(20)와, 상기 외피부(20)의 하단부에 형성되는 끝단부(30)와, 일단이 상기 끝단부(30)와 결합되고 타단이 의지(3)의 소켓(5)과 체결되는 어댑터
