A structure for clamping a built-in component in a hollow container, the container being formed by clamp molding using a pair of a first mold piece and a second mold piece, the first mold piece being for forming a first half of the container, the second mold piece being for forming a second half of the container, the structure comprising:

• a first column-shaped support member welded to an inner wall surface of the first half of the container and having a first connection portion and a first clamp portion;
• and
• a second column-shaped support member welded to an inner wall surface of the second half of the container and having a second connection portion and a second clamp portion,
• wherein the built-in component is clamped between the first clamp portion and the second clamp portion in the state that the first connection portion and the second connection portion are coupled to each other, and
• wherein the first clamp portion and the second clamp portion are formed on top end surfaces of the first and second column-shaped support members.
