The present invention relates to, and more particularly to. Body part； A user input unit provided on the other side of the body unit； An electric motor provided inside the body to generate rotational power； A control unit controlling the electric motor based on an input value received from the user input unit； A body, a one-way open and a through-hole formed in the body, and a right-hand rail groove and a left-hand spiral rail groove are formed on the inner circumferential surface of the body, and the right (右) A mover provided with a two-way spiral rail groove in which a direction changing portion in which a spiral rail groove and a left spiral rail groove are continuously connected is formed； And It includes； a rotor connected to the shaft of the electric motor, and a rotor having an insertion groove formed on one side and a rail groove mover detachably attached to the insertion groove and projecting outward to contact the bidirectional spiral rail groove. When the electric motor rotates in one direction, the rotor rotates, and the rail groove mover is guided to the two-way spiral rail groove, so that the mover slides along the passage, so that the rail groove mover moves in one direction and the other direction. Reciprocating, The body further comprises a vibration motor, A control switch for controlling whether each of the electric motor and the vibration motor is operated is provided in the user input unit, A control switch for controlling the power of each of the electric motor and the vibration motor is provided in the user input unit, A transmission is further disposed between the electric motor and the rotor, Reciprocating drive lead screw device, characterized in that for reducing the number of revolutions of the electric motor, the torque is increased to transmit the rotational force to the rotor.본 발명은 에 관한 것으로, 보다 상세하게는 에 관한 것이다. 몸체부；상기 몸체부 타측에 구비되며 사용자 입력부；상기 몸체부 내부에 구비되어 회전 동력을 발생시키는 전기 모터；상기 사용자 입력부로부터 입력받은 입력값을 기반으로 상기 전기 모터를 제어하는 제어부；몸체와, 일측
