Vehicle on-board device mounting structure

A vehicle on-board device mounting structure for a vehicle, wherein the vehicle includes:

• a differential device that splits drive power transmitted from a propeller shaft between two drive shafts;
• a motor that applies the drive power to the two drive shafts via the differential device;
• and
• an inverter that performs power conversion between a battery cell accommodated in a battery pack and the motor,
• the differential device includes:
• a differential case that accommodates two side gears respectively coupled to the two drive shafts, and a differential pinion that meshes with both of the two side gears;
• and
• a ring gear provided on an outer periphery of the differential case and receiving the drive power transmitted from the propeller shaft and the motor, and
• the vehicle on-board device mounting structure is configured such that
• the inverter and the ring gear overlap with each other when viewed in an axial direction of the drive shaft,
• the inverter and the ring gear do not overlap with each other when viewed in an up-down direction of the vehicle, and
• the inverter and the differential case overlap with each other when viewed in the up-down direction.
