The slide rails 29L and 29R are inclined so that the rear end portion is located below the virtual surface V.

As a result, the cooling air from the front of the vehicle can be introduced into the electrical component 10 from a position higher than the floor panel 2. Further, since the rear ends of the slide rails 29L and 29R are located behind the virtual surface V, the slide rails 29L and 29R can be arranged close to the upper side of the electrical component 10, so that the side collision of the vehicle 1 The external force from the vehicle side (right side) at that time can be received by the slide rails 29L and 29R, and the external force acting on the electrical component 10 can be reduced.
