High voltage device mounting structure of vehicle

A high voltage device mounting structure of a vehicle, the high voltage device mounting structure comprising:

• a casing, accommodating a high voltage device driven at a high voltage and disposed in an engine room of the vehicle;
• a cover member, covering an opening of the casing;
• and
• a side frame, extending in a front-rear direction of the vehicle at a side part of the engine room,
• wherein a first inclined part inclined inward in a vehicle width direction toward a rear of the vehicle is provided on a surface facing an outer side in the vehicle width direction in the cover member,
• a second inclined part inclined inward in the vehicle width direction toward the rear of the vehicle is provided on a surface facing an inner side in the vehicle width direction in the side frame,
• the first inclined part and the second inclined part at least partially face each other, and the first inclined part is inclined more than the second inclined part, and
• a rear end of the first inclined part in the cover member extends to a position behind a mating surface with the cover member in the casing.
