Abstract

A structure includes a sheet metal antenna as a first member, a rear-surface-side housing as a second member including a through hole, and a sealing portion which seals the through hole. The second member includes a space. The sheet metal antenna includes an intermediate portion as a pass-through portion which passes through the space and the through hole. The space includes a first region, a second region located opposite to the first region with the intermediate portion being interposed, and a third region which lies from one main surface of the intermediate portion to the other main surface thereof while it is in contact with both of the first region and the second region, and the second member includes an injection path as a groove continuing to the first region.

First claim

The invention claimed is:

1. A structure comprising:
a first member;
a second member including a first surface and a second surface which face opposite to each other and including a through hole; and
a sealing portion which seals the through hole, with the first member passing through the through hole,
the second member including a space which opens into the second surface adjacently to the through hole on the side of the second surface,
the first member including a pass-through portion which passes through the space and the through hole,
the space including
a first region,
a second region located opposite to the first region with the pass-through portion being interposed, and
a third region which lies from one main surface of the pass-through portion to the other main surface of the pass-through portion while the third region is in contact with both of the first region and the second region, and

the second member including a groove continuing to the first region.

2. The structure according to claim 1 , wherein
the sealing portion includes a sealant in the space and the groove includes a shape for positioning of an instrument for injecting the sealant.

3. The structure according to claim 1 , wherein
a portion of the groove closest to the first region is as deep as the first region and a bottom portion of the groove is inclined to decrease in depth as a distance from the first region is greater.

4. The structure according to claim 1 , wherein
the third region is in a rounded shape when viewed in a direction perpendicular to the second surface.

5. The structure according to claim 1 , wherein
the first member includes a sheet metal antenna.

6. The structure according to claim 1 , wherein
the second member includes a housing.

7. The structure according to claim 1 , wherein
the first member includes an extension portion which extends along the second surface on the side of the second surface of the second member and the first region is covered with the pass-through portion and the extension portion.

8. An electronic device comprising the structure according to claim 1 .

9. A method of manufacturing a structure comprising:
a first step of preparing a first member and a second member, the second member including a first surface and a second surface which face opposite to each other and including a through hole;
a second step of inserting the first member in the through hole;
a third step of injecting a sealant into a portion including the through hole after the second step; and
a fourth step of sealing the through hole while the first member and the second member are fixed relatively to each other by curing the sealant injected in the third step,
the second member including a space which opens into the second surface adjacently to the through hole on the side of the second surface,
the first member including a pass-through portion which passes through the space and the through hole,
the space including
a first region hidden by the pass-through portion and a portion which extends along the second surface on a side of the second surface of the first member,
a second region located opposite to the first region with the pass-through portion being interposed, and
a third region which lies from one main surface of the pass-through portion to the other main surface of the pass-through portion while the third region is in contact with both of the first region and the second region,

the second member including a groove continuing to the first region,
in the third step, the sealant being injected into the first region along the groove by applying a tip end of an instrument for injecting the sealant to the groove, and
in the third step, the sealant injected into the first region being located to surround the pass-through portion as the sealant moves from the first region via the third region to the second region.
