  By the way, in the structure in which the bracket is disposed on the front side of the conventional bore portion, distortion due to stress concentration is likely to occur in the recess center portion 20b 'of the bore portion 20b due to the input a from the container 23 at the time of bound and rebound, which is a rough road. There is a risk of cracking when traveling on the road.

  In order to prevent the occurrence of cracks due to such strain, it is conceivable to reinforce by arranging an L-shaped reinhose 24 on the bore 20b of the outer flange 20a. However, since the reinforcing bead 20c having a U-shaped cross section is formed at the lower edge of the bore portion 20b, it is necessary to arrange the reinhose 24 at a position away from the reinforcing bead 20c, and a sufficient reinforcing effect cannot be obtained. The problem arises. Although it is conceivable to increase the thickness of the loading platform, this causes a problem that the weight and cost of the vehicle body increase.

  The present invention has been made in view of the above-described conventional situation, and it is an object of the present invention to provide an automobile container mounting structure capable of reliably preventing the occurrence of cracks due to distortion without causing problems such as an increase in vehicle weight and cost. It is said.

  The present invention relates to a container mounting structure for an automobile in which a container is mounted on a loading platform and fixed to the loading platform, a concave bore portion is formed in the loading platform, and a fuel injection port is disposed in the bore portion. Brackets are arranged on both sides of the container, and the container is connected and fixed to the loading platform via the brackets.

  According to the container mounting structure according to the present invention, the brackets are arranged on both sides of the loading platform and the containers are connected and fixed to the loading platform via the brackets. Since both sides of the punched portion are connected to the container, distortion due to vehicle body vibration or the like can be suppressed. In other words, the input in the vertical direction is distributed to the brackets on both sides and distributed almost evenly to the carrier, so that both sides of the loading part of the loading platform move up and down so that they are in phase. Compared with the case of moving, stress concentration can be avoided, distortion can be suppressed, and cracks can be prevented from occurring.

Further, in the present invention, since it is a structure in which brackets are simply arranged on both sides of the bore portion, it is possible to reduce the weight as compared with the case where a conventional rein hose is added or the thickness of the loading platform is increased. At the same time, the cost can be reduced.
