The present invention relates to a motor unit for a sunroof. The motor unit for the sunroof of the present invention comprises: a lower housing; an upper housing; a bush; a worm wheel; a drive shaft; a pinion gear; a washer; and a lower cover. In particular, according to the present invention, abutment between the drive shaft and the lower cover is prevented, and the worm wheel is configured to abut against the washer and the bush. Therefore, it is possible to prevent generation of friction noise between metals. In addition, since there is no separation distance between the pinion gear and the washer, the washer and the bush, and the bush and the worm wheel, it is possible to prevent a change in a contact area due to the separation distance and occurrence of different noises due to the separation distance.

    본 발명의 선루프용 모터 유닛은 하부하우징, 상부하우징, 부시, 웜휠, 구동샤프트, 피니언기어, 와셔 및 하부커버를 포함하여 구성되며, 특히 상기 구동샤프트와 하부커버 간의 맞닿음을 방지함과 더불어 웜휠은 와셔 및 부시에 맞닿을 수 있도록 구성함으로써 금속간 마찰 소음의 발생을 방지할 수 있도록 하고, 피니언기어와 와셔, 와셔와 부시, 부시와 웜휠 간의 이격 거리가 존재하지 않도록 하여 이격 거리로 인한 접촉 부위의 변경 및 이로 인해 서로 다른 소음이 발생되는 현상을 방지할 수 있도록 한 것이다.
