a side member; and

a mechanical-electrical integrated unit attached to the side member through a fastener,

wherein the mechanical-electrical integrated unit is constituted by a drive apparatus and an electric-power control apparatus that are housed in a same casing,

wherein the drive apparatus includes an electric motor functioning as a power source,

wherein the electric-power control apparatus is configured to control an electric power transmitted and received by the electric motor,

wherein the casing has an upper space and a lower space that are vertically separated within the casing,

wherein the electric-power control apparatus is housed in the upper space while the drive apparatus is housed in the lower space,

wherein a plate is provided in the upper space, and

wherein the side member includes a fragile portion that is located in a position overlapping the plate as viewed in a width direction of the electric vehicle.

2 . The electric vehicle according to claim 1 ,

wherein the plate is disposed to be in contact with both inner surfaces of a pair of side walls of the casing which are opposed to each other in the width direction in the upper space.

3 . The electric vehicle according to claim 1 ,

wherein the plate is made of a material having a higher strength than the casing.

4 . The electric vehicle according to claim 1 ,

wherein the side member includes a fastening portion to which the fastener is attached, and

wherein the fragile portion is located in a position outside the fastening portion in a longitudinal direction of the electric vehicle.

5 . The electric vehicle according to claim 4 ,

wherein the side member has a strength that is gradually reduced away from an outer side toward an inner side until the fragile portion in the longitudinal direction.
