- outer periphery bead 42 is formed so that it may become convex shape to the food
- an outer periphery bead goes to the food
- a configuration in which all of the plurality of reinforcing beads are connected to the outer peripheral bead can be employed, or a configuration in which none of the plurality of reinforcing beads is connected to the outer peripheral bead can be employed.
- a configuration in which two of the three reinforcing beads are connected to the outer peripheral bead may be employed.
- a configuration in which a terminal portion extending in a direction extending from the stopper abutting portion is continuously provided without any step in the extending direction with respect to the flat portion of the panel is applied to all of the plurality of reinforcing beads. May be.
- step difference with respect to the plane part of a panel among several reinforcement beads can also be taken.
- the “at least one of the plurality of reinforcing beads” described in the third aspect of the present invention means at least one of “the plurality of reinforcing beads” described in the first aspect of the present invention. .
- the skeleton part and any one of the plurality of reinforcing beads may be connected by a connecting bead. Further, the skeleton part and all of the plurality of reinforcing beads may be connected by a connecting bead. Furthermore, the structure which does not have the connection bead which connects a frame
- the “at least one of the plurality of reinforcing beads” described in the fourth aspect of the present invention means at least one of “the plurality of reinforcing beads” described in the first aspect of the present invention. .
- connection beads 56 and 58 are formed so that it may become convex shape to the hood upper side (outer plate side), it is convex shape to the hood lower side (opposite side to the outer plate side). May be formed.
- the concept of “position not on the same line” described in the first aspect of the present invention includes, for example, the second reinforcing bead 52 such as the first reinforcing bead 50 with respect to the second reinforcing bead 52.
- the second reinforcing bead 52 is located at a part of the position close to the stopper contact portion 46 like the third reinforcing bead 54 with respect to the second reinforcing bead 52.
- what is present on the extended line is understood not to be on the extended line of the second reinforcing bead 52, and the same functions and effects as those obtained on the extended line are obtained. Includes a position recognized as “a position not on the same straight line”.

Abstract
Description
本発明の一実施形態に係る車両用開閉体構造について図1~図4Bを用いて説明する。なお、これらの図において適宜示される矢印FRは車両前方側を示しており、矢印UPは車両上方側を示しており、矢印Wは車両幅方向を示している。また、フード閉止状態では、フード前方側は車両前方側と同じ方向であり、フード上方側は車両上方側と同じ方向である。
次に、上記実施形態の作用及び効果について説明する。
なお、上記実施形態では、開閉体がフード30とされているが、開閉体は、例えば、車体後部の開口部を開閉可能に覆うバックドアや車体側部の開口部を開閉可能に覆うサイドドア等のような他の開閉体であってもよい。ちなみに、開閉体がバックドアの場合及び開閉体がサイドドアの場合、開閉体の内面(内板)を構成するパネルは、ドアインナパネルとされる。
