The electric auxiliary drive unit includes a crankshaft, a housing, a motor, and a decelerator. The housing is supported by the crankshaft via a first bearing in a radial direction. The motor and the decelerator are disposed in a space between the crankshaft and the housing. The motor has a stator and a rotor. The stator is fixed to the housing. The rotor is supported by the crankshaft in the radial direction via a second bearing. The rotor rotates in accordance with a load applied to the crankshaft. The decelerator decelerates the rotation of the rotor and outputs the rotation to the crankshaft.

    电动辅助驱动单元包括曲柄轴、外壳、电动机和减速器。外壳在径向上经由第一轴承支承于曲柄轴。电动机和减速器配置于曲柄轴与外壳之间的空间。电动机具有定子和转子。定子固定于外壳。转子在径向上经由第二轴承支承于曲柄轴。转子根据施加于曲柄轴的负载旋转。减速器使转子的旋转减速并输出到曲柄轴。
