A power control unit is located inside a housing chamber of a driving unit of a vehicle, and the power control unit includes a casing housing a power conversion device. The casing includes casing segments, and fastening parts are located around the casing segments. The casing segments are fastened to each other with bolts at the fastening parts, and the fastening parts include a specific fastening part on which a shear load concentrates when a load is input into the casing, and an ordinary fastening part other than the specific fastening part. The specific fastening part has an induction portion inducing plastic deformation, which is configured to lower an elastic limit of the specific fastening part when the load is input into the casing, such that the specific fastening part undergoes plastic deformation earlier than the ordinary fastening part.
