Description

The present disclosure relates to a mounting structure for vehicle-mounted components.

Patent Literature 1 discloses a mounting structure for a vehicle canister that adsorbs and captures fuel vapor. A mounting structure for such a vehicle canister includes a dash panel disposed in the rear of the vehicle in the engine room, a bracket attached to the dash panel, a substrate portion formed on the bracket and fixed to the dash panel, and a portion extending from the substrate portion to the engine room. A pair of left and right protruding plate portions which are formed to protrude to the side and are inclined so that the projecting tip portions approach each other, and a space formed on the outer peripheral surface of the canister and inserted into a space surrounded by the substrate portion and the protruding plate portion. The mounting portion is formed along the respective bases of the pair of projecting plate portions and on the inner portion of the substrate portion between the pair of projecting plate portions, and the length in the vertical direction is longer than the length in the vertical direction of the projecting plate portions. An opening, a fragile portion formed in a connection region between the base portion and the protruding plate portion, and ribs formed in the base portion along the edge of the opening from the upper and lower ends of the fragile portion.

According to such a vehicle canister mounting structure, when the vehicle receives an external force from the front of the vehicle, parts in the engine compartment move toward the dash panel, and when they come into contact with the canister, they become weak due to the difference in strength between the fragile portion and the rib. Stress concentration tends to occur in the part. Then, it becomes possible to break the projecting plate portion from the substrate portion with the fragile portion as a starting point. As a result, when the canister and peripheral parts come into contact with each other, the canister separates from the bracket and can be protected from external forces.
