LIQUID LEVEL DETECTION DEVICE AND MANUFACTURING METHOD OF LIQUID LEVEL DETECTION DEVICE

摘要

A housing of a liquid level detection device includes an inner case, which has a first wall portion, and a terminal, which has a projection that extends through the first wall portion and projects to an outside of the inner case. The first wall portion and the projection are covered with a covering portion. A first seal film, which connects between an outer peripheral surface of the projection and the first wall portion, is formed in an inside of the covering portion. A film thickness of the first seal film along an edge line of the terminal progressively increases toward the first wall portion.

主权项

1. A liquid level detection device for detecting a level of a surface of liquid, comprising:
a wall portion; a terminal that has a projection, which projects through the wall portion in a predetermined projecting direction; a covering portion that covers the wall portion and the projection; and a seal film that covers a corresponding portion of an outer peripheral surface of the projection and connects between the corresponding portion of the outer peripheral surface and the wall portion in an inside of the covering portion, wherein a film thickness of the seal film progressively increases toward the wall portion along the corresponding portion of the outer peripheral surface.
