Abstract: A float floats on a liquid inside a container and is movable upward and downward according to a liquid surface level. A cover is located inside the container and houses the float inside the cover. A detector detects the position of the float. The cover includes a support part and a wall part. The support part allows upward and downward displacement of the float and restricts displacement of the float outward from the cover. The wall part is located around the support part. The wall part has an opening that allows communication between the inside of the cover and the outside of the cover. The area of the opening is larger than the surface area of the wall part except the opening.

Abstract: The welding chip heats and melts the first welded part and the second welded part, and includes a projected part, a first extension part, and a second extension part. The projected part has a tubular shape with a bottom. One end of the tubular shape extending in a predetermined direction opens and the other end of the tubular shape is closed. The projected part is pushed into the first welded part and the second welded part in the predetermined direction from the opening one end of the tubular shape. The first extension part has a shape extending from a tube outer surface of the projected part and extending annularly around the predetermined direction. The second extension part has a shape extending from the first extension part to the opening one end of the projected part in the predetermined direction and extending annularly around the predetermined direction.
