The present invention relates to an in-wheel motor. An in-wheel motor according to an embodiment of the present invention comprises: a circular rim to which a tire is coupled by being wrapped around an outer ring thereof and a shaft is connected by passing through a center thereof; a motor assembly which is disposed in an inner portion of the rim and includes a stator connected to the shaft and a rotor disposed to be wrapped around the stator and configured to rotate; a cover coupled to cover one open side surface of the rim and configured to seal the inner portion of the rim; and a lead-out wire entry/exit portion waterproof structure configured to seal an entry/exit portion for a lead-out wire connected to supply power from outside of the in-wheel motor to the inner portion of the rim via a hollow portion of the shaft. The lead-out wire entry/exit portion waterproof structure includes an elastic stopper, to which the lead-out wire is connected to pass through a center thereof and which is configured to be elastically contracted after being inserted into the hollow portion of the shaft in an axial direction and seal between the hollow portion of the shaft and the lead-out wire, and a stopper fixing body fastened to the shaft and configured to press the elastic stopper in the axial direction so that the elastic stopper is inserted and fixed inside the hollow portion of the shaft.

    본 발명은 인휠모터에 관한 것으로서, 본 발명의 실시예에 따른 인휠모터는 타이어가 외륜을 감싸 결합되며 샤프트가 중심을 관통하여 연결되는 원형의 림, 샤프트에 연결되는 고정자와, 고정자를 감싸도록 배치되며 회전하는 회전자를 포함하며, 림의 내부에 위치하는 모터 어셈블리, 림의 개방된 일 측면을 덮어 결합되며 림의 내부를 밀폐시키는 커버, 및 샤프트의 중공부를 통해 인휠모터의 외부로부터 림의 내부로 전원을 공급하도록 연결되는 인출선의 출입부를 밀봉하는 인출선 출입부 방수구조를 포함하고, 인출선 출입부 방수구조는, 인출선이 중심을 관통하여 연결되며, 샤프트의 중공부에 축 방향으로 삽입 후 탄성 수축되어 샤프트의 중공부와 상기 인출선 사이를 밀봉하는 탄성 마개, 및 샤프트에 체결되며, 탄성 마개를 축 방향으로 가압하여 샤프트의 중공부 내부에 삽입 및 고정시키는 마개 고정체를 포함한다.
