The present invention relates to a back massager, in particular for a back massage device comprising a plurality of massage members using a solenoid is configured to be wrapped in the outer shell, A buffer base having a predetermined thickness and having a predetermined thickness and having a plurality of coupling holes penetrated therein so as to engage and engage the first massage member which is operated back and forth by a control signal of a controller, and the user is placed on the front of the buffer base. When the user is in close contact with the back of the buffer base is provided with a support surface formed to protrude inclined inwardly on both sides of the buffer base, the user is formed to protrude to the front of the upper end of the buffer base to lean against the buffer base It supports the neck, characterized in that the neck support, which is provided with a second massage member is installed so that both sides of the supported neck can be moved straight back and forth by the control signal of the control unit. According to the present invention, while forming a backrest with a support surface at both ends of the rectangular buffer base in which the massage member is installed to be inclined inward, a massage device is formed to protrude to the front on the upper end of the buffer base. Therefore, the user can close the back and neck to the massage device as much as possible to receive the massage at the same time, so that the user can relax the rigid neck and back in a short time with the comfort while receiving the massage. It is possible to expect an effect that can prevent the decrease in efficiency due to fatigue because it relaxes the rigid back of the office worker or students who sit and work or study for a long time.본 고안은 등받이용 안마기에 관한 것으로, 특히 솔레노이드를 이용한 다수의 안마부재가 외피에 감싸지도록 설치 구성된 것을 포함하는 등받이용 안마기에 있어서,상하로 길게 형성되며 소정의 두께를 가지면서 제어부의 제어 신호에 의해 전후로 작동되는 제1안마부재를 끼워 결합할 수 있도록 다수의 결합홀이 관통 형성된 완충베이스와, 사용자가 상기 완충베이스의 전면에 등을 밀착시키면 그 사용자의 등 양측이 밀
