| description | A drive unit for an electrically assisted bicycle includes a housing, a motor in the housing, a crank shaft extending through the housing along a right-left direction of the bicycle, and a pair of bearings rotatably supporting the crank shaft within the housing, wherein each bearing includes an inner ring and an outer ring. The pair of bearings include a first bearing at one side of a thrust direction and a second bearing at another side along the thrust direction, wherein the thrust direction is an axial direction of the crank shaft. The first bearing does not move along the thrust direction relative to the crank shaft. The drive unit has a movement restricting structure that restricts movement of the first bearing relative to the relative to the housing along the thrust direction. |
