摘要： A gear case of an in-wheel motor drive device houses first and second helical gears, has a first opening in its inner wall through which a motor main shaft passes, and has a second opening in its outer wall through which an axle passes. The in-wheel motor drive device further includes a first thrust bearing attached to the outer wall and supporting the first helical gear, and a second thrust bearing attached to the inner wall and supporting the second helical gear. The directions of helical teeth of the first and second helical gears are set so that when a motor vehicle travels forward, a thrust load directed outward in the vehicle width direction is applied to the first helical gear, and a thrust load directed toward the middle in the vehicle width direction is applied to the second helical gear.

摘要： An electric motor disclosed herein includes a stator core, a coil wound around the stator core, a terminal block, and a bus bar. The terminal block is disposed so as to face a side face of the stator core. The bus bar is connected to a lead wire of the coil, and is also fixed to the terminal block. The bus bar extends along the side face of the stator core in an axial direction of the stator core, and one end portion thereof is fixed to the terminal block by a bolt.
