Electric motor system

An electric motor system comprising:

• a gear;
• a first surface that receives oil scraped off as the gear rotates;
• a second surface that is located downward in a vertical direction with respect to the first surface, faces the first surface at a position overlapping the first surface in the vertical direction, receives the oil dropped from the first surface, and receives the oil scraped up as the gear rotates;
• and
• a recess located downward in the vertical direction with respect to the second surface and into which the oil collected on the second surface flows,
• wherein the first surface is inclined such that a side closer to the gear is located upward in the vertical direction and a side farther from the gear is located downward in the vertical direction in a horizontal direction perpendicular to the vertical direction and perpendicular to an axial center of the gear,
• the second surface is inclined such that an end closer to the gear is located upward in the vertical direction with respect to an end farther from the gear in the horizontal direction, and
• a flow path communicating with an inside of the recess is formed on a side of the end farther from the gear.
