Abstract

Official abstract text for this publication.

There is provided a fuel tank including: a tank main body that stores fuel at an interior and has a pair of wall portions that face one another; and a supporting pillar that spans between the pair of wall portions, wherein the supporting pillar includes a shaft portion that is disposed with an axial direction thereof being a direction in which the pair of wall portions face one another, a pair of flange portions that extend-out toward a radial direction outer side of the shaft portion from axial direction both end portions of the shaft portion, and that are joined to the pair of wall portions, and plural ribs that are formed at a periphery of the shaft portion, and that span between the shaft portion and the pair of flange portions, and that have weak portions that are weakened locally.

First claim

Opening claim text (preview).

What is claimed is: 1. A fuel tank comprising: a tank main body that stores fuel at an interior and has a pair of wall portions that face one another; and a supporting pillar that spans between the pair of wall portions, wherein the supporting pillar includes a shaft portion that is disposed with an axial direction thereof being a direction in which the pair of wall portions face one another, a pair of flange portions that extend-out toward a radial direction outer side of the shaft portion from the axial direction on both end portions of the shaft portion, and that are joined to the pair of wall portions, and a plurality of ribs that are formed at a periphery of the shaft portion, and that span between the shaft portion and the pair of flange portions, and that have weak portions that are weakened locally. 2. The fuel tank of claim 1 , wherein the weak portions are cut-out portions that are formed by portions of the ribs being recessed locally toward the shaft portion side. 3. The fuel tank of claim 2 , wherein the cut-out portions extend to an outer peripheral surface of the shaft portion. 4. The fuel tank of claim 2 , wherein a dimension, in the axial direction, of the cut-out portions becomes smaller the further toward a shaft portion side. 5. The fuel tank of claim 2 , wherein the weak portions are thin-walled portions formed in the ribs. 6. The fuel tank of claim 1 , wherein a dimension, in a radial direction of the shaft portion, of the ribs becomes smaller the further toward a weak portion side from the pair of flange portions. 7. The fuel tank of claim 1 , wherein one side of the ribs and another side of the ribs are formed so as to be separate in the axial direction of the shaft portion. 8. The fuel tank of claim 1 , wherein the weak portions are holes that are formed in the ribs.
